Abstract

The invention provides a preparation method for high-wear-resistant steel. The preparation method comprises the steps that high-chromium cast iron is taken as a base material, an alloy is added into the base material for smelting to obtain a blank, a workpiece obtains high wear resistance, toughness and strength, the blank is finely rolled into a wear-resistant plate with a preset size, a grouting bag filled with a bonding solution is stuffed into each T-shaped groove, T-shaped strips on the wear-resistant plate are inserted from the open ends of the T-shaped grooves to extrude the grouting bags inwards till the T-shaped strips are inserted into the innermost part of the T-shaped grooves, coatings of the grouting bags are extruded to be broken, the bonding solutions inside the grouting bags flow out and fill a gap between the wear-resistant plate and a base plate to form a bonding layer, and countersunk bolts on the two sides of the base plate sequentially penetrate through countersunk holes and threaded holes so as to tighten the base plate and the T-shaped strips. The wear-resistant plate and the base plate are combined together through the T-shaped strips and the T-shaped grooves, are bonded through the bonding solutions, and the wear-resistant plate and the base plate are firmly bonded, and then are tightened and locked through the bolts, so that the firmness of the wear-resistant plate and the base plate is further guaranteed.

Description

technical field [0001] The invention relates to the field of high wear-resistant steel production, in particular to a preparation method of high wear-resistant steel. Background technique [0002] Wear, corrosion, and fracture are listed as the three major failure modes of metal mechanical parts. The annual consumption of metal materials due to wear in my country has reached more than 3 million tons; modern industry urgently needs workpieces that can work effectively under harsh wear conditions. On the premise of ensuring the strength, stiffness and fatigue resistance of mechanical parts, how to improve the wear resistance of the material surface has become a hot spot in research and development. [0003] Wear-resistant composite steel plate is a kind of wear-resistant composite material produced by composite technology. It combines the advantages of wear-resistant alloy and matrix material in design, and makes up for their respective shortcomings. It has excellent comprehen...
