Abstract

The invention discloses an abrasion-resistant lining plate for a cone crusher and relates to the technical field of crusher lining plates. Alloy elements in the lining plate include 2.30-2.80% of C, 22.0-24.0% of Cr, 1.32-1.85% of Si, 0.15-0.23% of Mn, 0.17-0.32% of B, 0.25-0.40% of V, 0.15-0.28% of N, 0.15-0.26% of W, 0.54-0.82% of Cu, 0.02-0.06% of Ce, 0.15-0.22% of Al, 0.07-0.12% of Co, 0.22-0.35% of Ti and the balance Fe and unavoidable impurities. The ratio of the optimized elements is more reasonable and all the elements achieve the synergistic effect, so that the lining plate is high in hardness, good in tenacity and resistant to impact and abrasion; the service life of the lining plate is two to three times longer than that of a common steel abrasion-resistant material; the lining plate meets the work demands of medium and large cone crushers; besides, the raw material sources are rich, precious metal such as Mo and Ni are not contained, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of crusher liners, in particular to a wear-resistant liner for a cone crusher. Background technique [0002] Cone crusher is a material crushing machine, mainly used for crushing ores and rocks with medium or higher hardness, and widely used in crushing raw materials in metallurgy, construction, road construction, chemical and silicate industries. Compared with other crushing machines, cone crusher crushing has the advantages of high crushing efficiency, low energy consumption, and uniform product particle size. The lining plate of the cone crusher is the mortar wall and the crushing wall. It is the main component of the cone crusher and has the functions of lifting the grinding medium, grinding the ore, and protecting the grinding cylinder. Due to frequent strong impacts during use, its liner is prone to serious wear, which will lead to problems such as uneven product particle size, decreased production ef...
