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 invention belongs to the field of metal materials, and relates to a wear-resistant malleable cast iron material and a preparation method thereof. Background technique [0002] In the field of metal materials, wear-resistant cast iron has been widely valued as a low-cost wear-resistant material. [0003] CN87105171 A new process for producing malleable cast iron with a bismuth-substituting alloy, which uses a new type of alloy as an inoculant, which can promote the formation of white spots in malleable cast iron bad parts, instead of traditional metal pure bismuth. The alloy is extracted from the fume or electrolytic anode slime produced during metallurgical refining of copper, lead, and tin. During the metallurgical refining process, it is enriched into an alloy containing 15-30% bismuth, 60-70% lead and a small amount of other elements. Ferrosilicon, aluminum and this alloy are used for compound inoculation in front of the furnace, which can real...
