What is a wear-resistant material?

Wear-resistant materials are a large class of new materials with special electrical, magnetic, optical, acoustic, thermal, mechanical, chemical and biological functions. They are important basic materials in high-tech fields such as information technology, biotechnology, energy technology, and national defense construction. It also plays a very important role in transforming some traditional industries.

Wear-resistant materials are the core of the field of new materials, and play an important role in promoting and supporting the development of high-tech. In the field of global new materials research, wear-resistant materials 

account for about 85%. With the advent of the information society, special wear-resistant materials play an important role in promoting and supporting the development of high-tech. They are key materials in high-tech fields such as information, biology, energy, environmental protection, and space in the 21st century. They have become countries all over the world. The focus of research and development in the field of new materials is also a hotspot of strategic competition in the development of high technology in various countries around the world.

Classification

At present, wear-resistant materials mainly include the following categories: wear-resistant balls, wear-resistant steel plates, wear-resistant electrodes, wear-resistant ceramics, wear-resistant floors, wear-resistant rubbers, wear-resistant pipes, wear-resistant bearings, wear-resistant welding materials, resistant Grinding castings, cast stones, polymers, composite wear-resistant materials and other wear-resistant materials.

Wear-resistant ball is a new type of abrasive material. It plays an increasingly important role in building materials and mining industries. China's cement building materials and mining industries have a huge demand. In the early days, imported foreign wear-resistant products were used to solve domestic demand, but it was not a long-term solution. Therefore, since the 1980s, China's wear-resistant ball industry has formed a complete industrial chain and industrial foundation from raw materials, production equipment, product research and development.
In the short term, the domestic market demand will be resolved. Due to the lack of core technical personnel, the lack of advanced production equipment, and the lack of national policy support, the domestic wear-resistant R&D and production technology has always been behind the international level, and the export volume is limited. Most of the products are mainly for solving domestic demand. The industry requirements are getting higher and higher, and the quality demand has gradually evolved from the previous quantity demand to the present. According to statistics, the demand for wear-resistant balls increased from 850,000 tons to 1.5 million tons from 2006 to 2010.
Take the cement industry as an example. In recent years, the domestic economy has developed rapidly, and the demand for highways and the construction industry is large. The cement production volume has increased year by year. The cement industry has increased the output, and the attribute requirements of wear-resistant balls have also been correspondingly improved. The development from low chromium content Wear-resistant balls with high chromium content and even higher grinding efficiency are in urgent need of research and development. However, most domestic manufacturers of wear-resistant balls are private enterprises, with limited funds and insufficient technical research and innovation capabilities. The gap in level is gradually widening.
