A Method to Solve the Defects of Wear-resistant Castings
Wear-resistant Castings are a common part, but Wear-resistant Castings still have a lot of defects. But we do not know how to solve, the following to introduce the way to solve the defects of Wear-resistant Castings.
1, a reasonable design, first into the thick layer of metal into the first solidification, so that the thin wall at the solidification, so that the same thickness of the same casting.
2, change the position of the runner.
3, low temperature fast burning, the metal liquid fast, smooth, balanced full of molding.
This is the way to improve the overall defect of Wear-resistant Castings, and there are many manufacturers through the above described method to change the Wear-resistant Castings production defects.
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 like its name as a great wear resistance, so in the choice of materials should choose high wear resistance materials. Today introduced the types of Wear-resistant Castings.
There are two kinds of materials that can be used as Wear-resistant Castings, one is GB / T12229-2005 WCB, and the other is ASTM A351 CF8M. This kind of material is the most important material of wear-resistant casting. After the material is selected, after the normalizing or normalizing, tempering treatment, in the acid cleaning surface debris, so that Wear-resistant Castings more smooth, in the entire production is completed, but also in the intensity of inspection, So that Wear-resistant Castings official factory sales.
Wear-resistant Castings in China has been 100 years of history, and its toughness, good wear resistance, and there are good deformation characteristics, so in the industrial and machinery industry 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 wear-resistant casting life for how long.
Wear-resistant Castings in the production process are using high-tech materials, and in order to improve the Wear-resistant Castings wear 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 in the maintenance work, but also extend the life of Wear-resistant Castings.
Wear-resistant Castings In the production process, heat treatment is very important, if there is a little difference in temperature 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 the 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.
