Abstract

The invention provides a large crusher abrasion-resistant hammer and a preparation method thereof. Elements in raw materials include, by weight, 1.9-2.7% of C, 7-9% of Cr, 0.7-1.1% of Mn, 0.4-0.7% of Mu, 0.3-0.5% of Cu, 0.9-1.3% of Ni, 0.2-0.4% of Si, 0.1-0.3% of Ti, 0.2-0.4% of Be, 0.4-0.7% of rare earth and the balance Fe and impurity components not capable of being removed. The abrasion resistance of the large crusher abrasion-resistant hammer can be further improved through alloy smelting, modification treatment, casting, quenching and tempering, the improvement of the ductility of the hammer is increased, and production and processing treatment and industrialized production and processing are convenient.

Description

technical field [0001] The invention relates to the field of wear-resistant materials, in particular to a wear-resistant hammer head of a large crusher and a preparation method thereof. Background technique [0002] With the current industrialization, the application of wear-resistant materials in the industry is becoming more and more extensive, especially for the current wear-resistant process parts, which require a large amount of practical production while producing and processing, the requirements for wear-resistant equipment and structural strength The indicators of traditional Chinese medicine are proposed. [0003] The hammer head of the crusher is one of the core components of the crusher. The hammer head strikes the material in the high-speed operation of the crusher, and finally crushes it into a suitable particle size. Crusher hammers on the market can be divided into two types according to the manufacturing process: casting and forging, but their wear resistanc...
