Problems solved by technology

[0004] During the use of the vertical mill roller body and the wear-resistant liner, once there is a fit gap, the wear between the body and the liner will be aggravated, and the hot air and cement particles will continuously scour the mating surface, resulting in grooves. Causes impact and collision between the body and the liner. In severe cases, the liner cracks or even breaks, and the machine is damaged, especially the damage of the reducer, resulting in a vicious incident.

Abstract

The invention belongs to the technical field of wear-resistant materials, and particularly relates to a wear-resistant and corrosion-resistant liner plate and a preparation method thereof. The wear-resistant and corrosion-resistant liner plate is prepared from the following components in percentage by weight: 0.6-1% of carbon, 0.4-0.8% of silicon, 0.4-0.85% of magnesium, 0.4-1.0% of manganese, 9-13% of chromium, 1.5-1.9% of molybdenum, 0.1-0.22% of nickel, 0.05-0.20% of titanium, 0.005-0.04% of phosphorus, 0.005-0.04% of sulfur, and the balance of iron. A formula is reasonable, manufacturing is easy, the service life is long, quite high strength, toughness, wear resistance and impact resistance are achieved, the frequency of replacing the wear-resistant and corrosion-resistant liner platein a factory is reduced, the labor intensity is lowered, raw materials are easy to obtain, a manufacturing method is simple, and energy is effectively saved.
