Two basic specialties of stainless steel casting process


Because the shortening of fine casting of stainless steel is much greater than that of cast iron, in order to avoid the defects of shrinkage and porosity, riser, chill and subsidy are mostly used in casting technology to complete sequential condensation.
In order to avoid shrinkage, porosity, porosity and cracks in stainless steel casting, uniform wall thickness, sharp and right angle structure, sawdust addition in moulding sand, coke addition in moulding core, and hollow core and oil sand core selection should be made to improve the concession and permeability of sand moulds or cores.
Due to the poor fluidity of molten steel, in order to avoid cold insulation and lack of pouring, the wall thickness of steel castings should not be less than 8 mm; dry or hot casting models should be selected; proper pouring temperature should be improved, generally from 1520 to 1600 C. Due to the high pouring temperature, the superheat of molten steel is high, and the time to keep liquid is long, so the fluidity can be improved. However, too high pouring temperature can cause coarse grain, hot cracking, porosity and sand sticking.
Therefore, the pouring temperature of fine castings with small size, thin wall and disorderly shape is about steel melting point temperature + 150 C; the structure of the pouring system is simple and the cross-section size is larger than that of cast iron; and the pouring temperature of large and thick-wall castings is about 100 C higher than that of cast iron.

Analysis of various types of precision casting materials


Castings have a great influence on mechanical products. Mechanical properties depend to a large extent on the quality and performance of castings. Therefore, mechanical products have high requirements for castings. Mechanical products require that castings have working durability under different conditions, including Wear resistance, corrosion resistance, chilling heat, fatigue, shock absorption and other properties as well as machinability, weldability and other process properties. These quality properties have a direct impact on the working efficiency and service life of mechanical products. Different casting materials make the performance characteristics of the stainless steel casting itself different.
Cast steel production is relatively stable, while the quality, variety, performance of steel castings and the proportion of alloy steel and special steel continue to increase. The use of various refining processes and technologies to develop new cast steel materials can improve the toughness and special properties of materials.
Casting light alloys will be widely used in aerospace, aerospace, automotive, machinery and other industries due to their excellent density, high specific strength and corrosion resistance. In the automotive industry, in order to reduce fuel consumption and improve energy efficiency, the replacement of steel and iron castings with aluminum and nickel alloy castings is a long-term development trend. It focuses on solving pollution-free, high-efficiency, easy-to-use refining technology, metamorphism technology, grain refining technology and rapid pre-furnace detection technology. In order to further improve the material properties and maximize the potential of materials, high-quality aluminum alloy materials, especially aluminum-based composite materials, can be developed to meet the performance requirements of different working conditions, strengthen the research of cluster alloy technology, and continue the alloy die-casting and extrusion casting process. And research and development of related technologies; Improve the research and development of ferroalloy smelting equipment and related technologies and processes.
Composite materials will become a new type of engineering materials for the 21st century. Casting composite materials will focus on the development of metal matrix composite base materials and reinforcing and strengthening component materials, and accelerate the development of their applications.
Iron is our most common casting material. The low cost, high processability and remelting regeneration of cast iron parts save resources and energy, so the application and development of this material is enduring. Widely used advanced iron liquid desulfurization and filtration technology; Thin wall high strength cast iron parts manufacturing technology; Cast iron composite material manufacturing technology; Surface or local strengthening technology of cast iron parts; Isothermal fire ductile iron complete set technology; Metal casting and metal type Special techniques and equipment such as sand casting and continuous casting.
With the continuous development of the national economy, the performance requirements of mechanical equipment are getting higher and higher. Therefore, castings of important components that make up mechanical products also need to be improved and improved in terms of quality and performance, and the entire mechanical quality is improved from local quality. Product performance.

What is the price of the ultrafine mill that the customer wants?


Ultra-fine mill is a popular word in the powder industry machinery, whether it is food or medicine, or ultrafine mill equipment such as Shanghai SBM processing ore, customers are very diverse in terms of grinding requirements, but The customer’s demand is based on the market demand of the powder products, so the ultrafine mill technology will not be too difficult, so for the price, the customer has something to say, the price of the ultrafine mill that the customer wants. What is it?
For mining machinery manufacturers, the cost price of sales is too large for sales and construction, because for large machinery such as ultrafine mills, he is not a fast-moving consumer. For enterprises, work and production personnel have strict requirements, in the production and sales of products is even more difficult. With the development of science and technology, the survival of ultrafine mill manufacturers is even thinner.
However, the industry has industry rules, and the price of ultrafine mills is based on how companies invest in products. The size of the investment largely determines the price of the product. Some customers often miss out on the quality equipment when they purchase ultrafine mill equipment. We can’t help wondering, what is the price of the ultrafine mill that the customer wants?
For the customer, as long as the production of ultrafine mill can meet the required production and fineness of production technology requirements, the after-sales service of the manufacturer is comprehensive and the price is acceptable. I believe it will be a good cooperation. For the manufacturer, consider the degree of the customer’s investment in the follow-up, the price should not be too preoccupied, because in the future everyone will have the opportunity to cooperate; for the customer, we must consider the manufacturer to invest in each ultrafine mill Painful
In short, the question of how much the price of the ultrafine mill that the customer wants is, the answer is, empathy, so good to discuss. The price level is not the deciding factor in the production of ultrafine mill. A high-quality processing equipment should have its worth price.

How to deal with accidents in the production of sand making machine


How to deal with the accident situation of the sand making machine production? The office of the Shanghai SBM Heavy Industry Sand Making Machine has summed up the problems arising from the production of the sand making machine in the past year. Today, how to deal with the unexpected situation: 1. Installation position of the sand making machine: cavity The pressure and flow inside the body can improve the production efficiency, but in the case of the two premise, the sand making machine parts should be installed in place as much as possible. For example, the height of the grinding roller and the grinding ring should be kept horizontal, and the eccentric rubber sleeve can be used to adjust the level; the blade between the blade and the grinding roller should maintain a gap of about 10 cm and maintain an angle of 23 degrees with the grinding bottom.
2. Evenly feeding: the speed of feeding will often enter a misunderstanding. The larger the quantity, the better, the output will increase. This is not the case. If the amount is too large, it will cause poor mechanical operation. As the saying goes, even sand is made. sand making machine; therefore, the feeding should follow the principle of uniform feeding, not too large or too small.
3. The influence of the humidity of the material: Most of the mills on the market are dry and brittle, and the materials with low water content have good milling effect, high speed and high efficiency; on the contrary, they are sticky and soft, sticky and hard, including The material with large amount of water is easy to stick to the blade of the blade, resulting in poor mechanical operation and low production efficiency.
4. Lower pressure valve: can only be pressed down, never lift up, otherwise it will cause the mill to leak, it takes about five minutes, the pressure inside the cavity is enough, can continue to discharge.
In the actual operation process, if the accident situation is often encountered, resulting in the equipment can not be produced normally, it is because of lack of experience, not good at summing up in the usual work. I hope that everyone can do a good job of the above four points in the future production, pay attention to the details, and ensure the smooth progress of production. As long as we do this, we can quickly increase the productivity of our equipment.

7 questions to be aware of when using the mill


The milling machine is the earliest grinding equipment used in China. It is mainly used for grinding of materials in mining, metallurgy, chemical industry and building materials industries. When using the Trapezium mill, we are thinking, how to make the mill high output, good quality, long use time, in fact, very simple, as long as you pay attention to several aspects when using, you can achieve this effect.
The problems that need to be paid attention to during the use of the mill are mainly reflected in the following seven aspects:
1. During the use of the mill, there should be a fixed person responsible for the care, the operator must have a certain level of technology. Before the installation, the operator must carry out the necessary technical training to understand the principle performance of the mill and familiar with the operating procedures.
2. Since the mill is generally working outdoors, the broken material is some large ore. Therefore, the operator of the mill must always pay attention to it. It is strictly forbidden to enter the machine and find that it will be stopped immediately, otherwise it will be damaged. Grinding roller and grinding ring;
3. In the use of the mill, it is necessary to strictly control the moisture of the material. Materials with too high water content can easily cause the fine powder in the mill to be too viscous and occupy the abrasive body, which seriously affects the quality and yield of the product.
4, must be in accordance with the prescribed standards to do the feeding, otherwise it will cause the final particle size is uneven, thick, fine, affecting the grinding effect.
5, to grasp the adjustment of the air volume, according to the fineness, production requirements to adjust properly; whether the air volume is too large or the air volume is too small will have a bad impact on the final effect of the mill’s raymond mill.
6. After the grinding machine is used for a period of time, it should be repaired. At the same time, the wearing parts such as the grinding roller and the blade should be repaired and replaced. The grinding roller device should be carefully checked before and after use to see if there is looseness. Phenomenon, whether the grease is added.
7. Master the correct method of stopping the machine. Stop the feeding before stopping the machine. After a while, wait until the material in the machine room has no remaining material. Then the power can be cut off. After stopping the grinding work, stop the fan motor. In order to blow off the residual powder.
