摘要：

Crusher is widely used in electricity, building materials, metallurgy and mining industry. Crusher liner is the key component of crusher for bearing load. The operations efficiency and production cost of crusher are directly affected by the performance and service life of crusher liner. Therefore, crusher liner is required to have good mechanical properties, impact toughness and abrasive resistance. Aiming at the low wear resistance and short service life of commonly used crusher liner, a new type complex low-alloyed wear-resisting crusher liner is researched. According to the production process of crusher and the performance requirement of crusher liner, the chemical composition is devised. The casting process and heat treatment process are researched. Field trial manufacture and corresponding performance experimental investigation are performed. It is shown from the result of experiment that the Rockwell hardness of this complex low-alloyed wear-resisting steel is above 50 HRC and the impact toughness is above 18 J/cm2. So the liners have better mechanical performance and wear resistance. Production and industrial test shows that the service life of this new liner is much longer and the economic and social benefit is significant. © 2013 Journal of Mechanical Engineering.
