Abstract

The invention discloses a wear-resistant lining plate of a bucket wheel machine hopper and a manufacturing method thereof. The lining plate comprises the following components in percentage by weight:0.5-0.8% of C, 0.1-0.3% of Ge, 1.5%-2.0% of Mn, 0.05%-0.1% of Tc, 0.2%-0.5% of Cu, 0.4%-0.8% of Zr, 0.05%-0.08% of Ta, 0.01%-0.03% of Y, 0.02%-0.04% of Ho, 0.05%-0.1% of silicon boride, less than or equal to 0.03% of S, less than or equal to 0.03% of P, and the balance Fe. The manufactured wear-resistant lining plate has the advantages of higher hardness, wear resistance, impact toughness and fatigue strength, and can effectively improve the ball milling efficiency.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a wear-resistant liner for a bucket wheel hopper and a preparation method thereof. Background technique [0002] Bucket wheel stacker and reclaimer and mixing reclaimer are efficient equipment for continuous loading and unloading of bulk bulk materials in modern industry. Because they have dual functions of reclaiming and stacking, they are widely used in ports, wharves, metallurgy, cement, steel Plants, coking plants, coal storage plants, power plants and other bulk material storage yards can greatly improve production efficiency, such as stacking ore, coal, coke, sand and gravel. [0003] When the bucket wheel stacker reclaimer and the mixing reclaimer work, they rely on the bucket on the wheel body to directly act on the material for excavation and reclaiming. When the bucket excavates the material, the material is cut into the material by the bucket edge fight. Ther...
