Analyzing the working conditions of the crusher parts, the wear-resistant parts are required to have high wear resistance. The wear resistance of crusher accessories depends on wear-resistant materials. Wear-resistant materials have undergone several important changes since their birth. The wear resistance of crusher accessories is closely related to wear-resistant materials, and the research and development of wear-resistant materials in China has never been interrupted. Let's take a look at the development history of wear-resistant materials for crusher accessories.
The first generation of wear-resistant materials: high manganese steel. After water toughening treatment, the surface of high manganese steel, which was first proposed in 1882, was work-hardened due to structural changes such as twin deformation under high impact load and high extrusion stress, but the core still maintained good impact toughness. It is widely used in crusher parts industry.
The second generation of wear-resistant material: hard nickel cast iron. With the development of the crushing machinery industry, more and more problems have emerged, such as the expansion of the crushing field and the requirements of equipment durability, and the continuous development of the industry has put forward higher requirements for wear-resistant materials. The hard nickel cast iron that appeared around 1930, with hardness up to HRC55-60, was used in some small parts.
Third generation wear-resistant material: high chromium cast iron. It has the characteristics of high alloy content, good fluidity, large shrinkage and poor thermal conductivity. The deficiency of high chromium cast iron is hard brittleness and high price.
The working efficiency of crusher parts is closely related to wear-resistant materials, and the new wear-resistant materials are still in continuous research and development, which leads to the crusher industry in China to better serve the modernization construction. Users can choose and wear resistant materials for crusher accessories according to working conditions and processing materials.以上翻译结果来自有道神经网络翻译（YNMT）· 通用场景
