Tube Mills Auxiliary Equipment Wear-resistant materials in different stages of development to reduce the unit material consumption has played a very big role, but the material performance there are some problems, such as ordinary white cast iron toughness is low, high manganese steel under low impact load hardening ability, High chromium cast iron in the corrosive medium under the wet grinding conditions have little advantage of wear resistance, while toughness is also insufficient. Due to the lack of toughness, the abrasive media is often broken and peeled off, which reduces the productivity of the grinding mill, reduces the grinding efficiency, increases the energy consumption, and wears the auxiliary equipment of the grinding closed loop. The project uses a small amount of alloying and isothermal quenching heat treatment of technical measures to develop a carbide containing isothermal quenching ductile iron (CADI) toughness wear-resistant materials for metallurgy, mining, cement, power generation,Tube Mills Auxiliary Equipment modern agriculture and other industries to provide a quality Of the anti-wear materials.

Adjust the alloy composition, can easily control the CADI matrix carbide content, thus regulating the toughness and hardness of the alloy, for different application environments, the development of different toughness of the components

The performance of CADI material is mainly determined by isothermal quenching process, which is determined by the austenitizing temperature and holding time,Tube Mills Auxiliary Equipment isothermal quenching temperature and holding time;

CADI ductile iron preparation process is simple and easy to implement, low cost, in the existing ductile iron production equipment can be directly produced.

 In order to improve the wear resistance of anti-wear materials, scientists have done a lot of research on abrasive materials. Wear-resistant materials can be divided into three stages: the first ordinary white cast iron and high manganese steel, the second is nickel hard cast iron, the third is high chromium white cast iron. The wear-resistant materials in the different stages of development to reduce the unit material consumption has played a very big role, but the material performance there are some problems,Tube Mills Auxiliary Equipment such as ordinary white cast iron toughness is low, high manganese steel work under low impact load hardening , High chromium cast iron in the corrosive medium under the wet grinding conditions, little advantage of wear resistance, while toughness is also insufficient. Due to the lack of toughness, the abrasive media is often broken and peeled off, which reduces the productivity of the grinding mill, reduces the grinding efficiency, increases the energy consumption, and wears the auxiliary equipment of the grinding closed loop. Therefore, people want to develop more tough anti-wear materials.

Under normal circumstances, to improve the performance of wear-resistant alloy is based on the increase in alloying elements on the basis of the current worldwide, a variety of ferroalloy prices soared, leading to wear-resistant materials manufacturing costs rising. At present, China's use of anti-wear materials are mainly chrome-based anti-wear materials, such as low-chromium cast iron, high-chromium cast iron. And China is a chromium resource poor countries, 90% of the ferrochrome need to import, nearly 10 years,Tube Mills Auxiliary Equipment high carbon ferrochrome prices turned 4 to 5 times. According to this reality, the development of wear-resistant materials suitable for China's national conditions, so that scientific and rational use of existing resources, in order to sustainable development of the national economy, for future generations, should cherish the valuable strategic resources, the development of less with chromium or not Chromium material, instead of chrome-based wear-resistant materials.

Therefore, the project intends to adopt a small amount of alloying and heat treatment to strengthen the technical measures to strengthen the development of carbothermal isothermal quenched ductile iron (CADI) toughness and wear-resistant materials for metallurgy, mining, cement,Tube Mills Auxiliary Equipment power generation and other industries to provide a quality Of the anti-wear materials.
