Wear-resistant Castings life
Wear-resistant Castings in China has more than 100 years of history, and its toughness, good wear resistance, and there are good deformation characteristics, so in the industrial and mechanical industries widely used. But everyone in the use of the process to know the advantages of Wear-resistant Castings there are many, but still worry about the life of Wear-resistant Castings for how long.
Wear-resistant Castings in the production process are used high-tech materials, and in order to improve the wear resistance of Wear-resistant Castings and grinding efficiency, have begun to use high materials, and the introduction of international advanced production technology to improve resistance Wear resistance of castings. In fact, we do not have to worry about the life of Wear-resistant Castings, under normal circumstances Wear-resistant Castings can be used for 20 years, if the work done in the maintenance work, but also extend the life of Wear-resistant Castings.
Wear-resistant cast ball is a Wear-resistant Castings in a part, while casting ball in the machinery industry often used, there is a very important role. The following let the Wear-resistant Castings introduced wear-resistant cast ball characteristics.
1, the ball surface rough, and the surface hardness is high, can support a lot of gravity.
2, the ball inside the loose, the impact of toughness is small, the greater the ball, the greater the mill.
3, wear-resistant cast ball is not suitable for wet grinding: If there is too much wet grinding, will result in increased costs, lower production.
Wear-resistant Castings have a high wear resistance, so they can be widely used in different industrial sectors. Although Wear-resistant Castings have a lot of advantages, but the production of good Wear-resistant Castings or a lot of requirements and standards. Today I mainly introduce the standard of Wear-resistant Castings.
1, Wear-resistant Castings to choose a wear-resistant material, the wear resistance to reach 63HRC level.
2, while Wear-resistant Castings in the production process to talk about a variety of production standards, can not be missing any one of the steps, and in the heat treatment process, very important.
3, after the production of Wear-resistant Castings can not have cracking, fracture, hair and other issues.
4, the hardness of Wear-resistant Castings to meet the relevant national standards, so as to protect the Wear-resistant Castings in the work of security.
Wear-resistant Castings In the production process, heat treatment is very important, if there is a little temperature difference will affect the quality of the product. The following describes the wear-resistant casting heat treatment process.
When the Wear-resistant Castings formed, let the high temperature of the furnace for processing. The principle of Wear-resistant Castings is generally fast and uniform, easy to control and efficient low cost. In the heat after the insulation treatment, mainly to prevent Wear-resistant Castings in a cold and a heat there will be cracks in the emergence of insulation time is generally longer than the heating time to 2 times. The last step is to cool, cooling is Wear-resistant Castings is also very important, if not timely cooling will not affect the toughness of Wear-resistant Castings. Wear-resistant Castings in the cooling process often use oil, water, salt and other materials.
Wear-resistant Castings in the production process, but also rough and rust treatment, to the real sales to the outside world. The following is a detailed description of roughing and rust treatment.
Roughing: that is, in the Wear-resistant Castings before the local rough processing, after roughing in time to find Wear-resistant Castings defects, and be modified to reduce the weight of Wear-resistant Castings.
Anti-rust treatment: In order to prevent Wear-resistant Castings in the transport process has the problem of rust. In general this step is in the test after the product coated with anti-rust material.
