Abstract

The invention provides an abrasion resistant malleable cast iron material and a preparation method thereof. The material has good performance, and the preparation method for the material is simple in process and low in production cost, and is suitable for industrial production. The abrasion resistant malleable cast-iron material takes malleable cast iron as a matrix; a metal wire group formed by high carbon steel wires and iron wires is distributed in the matrix; both the diameter of the used high carbon steel wires and the diameter of the used iron wires are 1 to 2 millimeters; the material contains 5 to 40 volume percent of the high carbon steel wires and the iron wires; and the diameter of the metal wire group is 10 to 15 centimeters.

Description

Technical field [0001] The present invention is a metal material field, involving a wear -resistant forged cast iron material and its preparation methods. Background technique [0002] In the field of metal materials, wear -resistant cast iron has been widely valued as low -cost wear -resistant materials. [0003] CN87105171 A new process of forging cast iron with alloy alloys is used. It is added with a new alloy as a breeding agent, which can promote the forged cast iron bad items into white mouths, instead of traditional metal pure pupa.This alloy is proposed in the dust or electrolytic anodonal mud generated by copper, lead, and tin metallurgy. In the process of metallurgy refining, it is enriched to 15-30 %, lead 60-70 % of the lead and contains a small amount of other elements.In front of the furnace, silicon iron, aluminum, and the alloy compound are bred, which can achieve low temperature annealing at a low temperature of 720 to 750 ° C.The price of the alloy is only 1 / 2 ...
