Embodiment 1

[0021] (1) Smelting: Add clean and dry ordinary steel scrap, pig iron, stainless steel scrap, ferromolybdenum, nickel plate, and carbon-increasing waste electrodes into the smelting furnace, heat and melt, raise the temperature to 1550°C, and add them 10 minutes before tapping The preheated ferromanganese and ferrosilicon are subjected to precipitation deoxidation, the composition is adjusted, and then the preheated cobalt plate is added. When the temperature of the molten iron reaches 1550°C, the method of deep insertion of aluminum wire is used for diffusion deoxidation;

[0022] (2) Pouring: Break the high-efficiency composite modifier into small pieces with a particle size of less than 45mm. After drying at 250°C, wrap it with iron sheet or tin foil paper and place it at the bottom of the ladle, and use the method of pouring into the ladle to modify the molten iron. , and then pour the molten steel into the steel ingot mould, the pouring temperature of the molten steel is 1...

Abstract

The invention relates to the technical field of wear resistant metal materials, and discloses a large crusher hammerhead and a making method thereof. The large crusher hammerhead comprises 2.2-3.2wt% of C, 15-20wt% of Cr, 0.3-0.7wt% of Si, 0.3-1.0wt% of Mn, 1.3-2.0wt% of Mo, 0.3-1.0wt% of Ni, 0.3-1.0wt% of Co, 0-0.3wt% of V, 0-0.2wt% of Ti, 0.1-0.5wt% of W, 0.005-0.025wt% of S, 0.005-0.025wt% of P, 0.05-0.2wt% of RE, and the balance Fe. The large crusher hammerhead has the advantages of reasonable formula, simple making, long service life, very high strength, toughness, wear resistance and impact resistance, reduction of the hammerhead replacement frequency of a factory, labor intensity reduction, easily available raw materials, simple making method and effective energy saving.

Description

technical field [0001] The invention relates to the technical field of wear-resistant metal materials, in particular to a hammer head of a large crusher and a preparation method thereof. Background technique [0002] With the rapid development of new dry-process cement large-scale equipment technology, domestic 5000t / d and 10000t / d large-scale dry-process cement production lines are increasing day by day. Limestone is the main raw material for cement production. In order to ensure sufficient supply, most cement production plants use large single-stage rotor hammer crushers for crushing. As a key wearable part of a large limestone crusher, the hammer head needs to withstand the strong impact of large materials during operation, and requires good impact toughness and high hardness. Due to the large differences in limestone quality, rotational speed, feed particle size, and comprehensive moisture of materials among cement manufacturers, the service life of hammers made of the ...
