Abstract

The invention is specifically a high-toughness and wear-resistant hammer head and a preparation method thereof, which solves the problem that the existing hammer head has severe eccentric wear and easily causes production accidents when crushing scrap steel. The body of the hammer head is integrally cast from the tail of the hammer head and the crushing part of the hammer head. There are symmetrical groove-shaped crushing blades on the left and right sides of the hammer head crushing part. Arc-shaped structure; hammer head body is composed of the following mass percentages of raw materials: carbon 0.95-1.05, silicon 0.3-0.8, manganese 12.4-14, phosphorus ≤ 0.07, sulfur ≤ 0.05, chromium 0.7-1, molybdenum 0.3-0.6, vanadium ≤ 0.3, titanium ≤ 0.3, rare earth ≤ 0.03, the balance is iron. The invention reduces the cracking phenomenon of the hammer head, improves the crushing efficiency, eliminates the occurrence of casting defects, and improves the mechanical properties at the same time.

Description

technical field [0001] The invention relates to a hammerhead of a scrap steel crusher for recycling scrap steel, in particular to a hammerhead with high toughness and wear resistance and a preparation method thereof. Background technique [0002] The scrap steel crusher uses a high-speed rotating hammer head to impact and crush the scrap steel and other materials entering the machine, and impacts the material toward the chopping board at high speed, and after falling into the lower body, it is sheared and squeezed by the hammer head and the grate plate. When the block degree meets the requirements, it is discharged from the grid of the grate plate. [0003] When steel scrap collides with a high-speed rotating hammer head, such as a frontal impact, the impact force of the material is completely converted into a compressive stress on the hammer surface. When the material is long or hits the hammer head at a certain angle, the impact force is decomposed into vertical hammer sur...
