Laser cladding process and auxiliary equipment thereof for wear-resistant plate

Abstract

The invention relates to the technical field of wear-resistant plate production and processing and particularly discloses a laser cladding process and auxiliary equipment thereof for a wear-resistant plate. The laser cladding process comprises the following step that step1, the cladding surface of a base material plate is polished, after redundant scrap iron is removed, the surface of the base material plate is washed, industrial alcohol wiping is performed, and dust on the surface is fully removed. By means of the laser cladding process and the auxiliary equipment thereof for the wear-resistant plate, iron, cobalt and nickel alloy powder covering the base material plate can be extruded and compacted, the situation that a large number of gaps exist among the iron, cobalt and nickel alloy powder, consequently, a large number of bubbles are generated in a wear-resisting layer during follow-up laser cladding, and the wear-resisting effect of the wear-resisting plate is affected is avoided, meanwhile, the gaps among the iron, cobalt and nickel alloy powder are removed, the iron, cobalt and nickel alloy powder is not prone to generating bubbles when being cladded on the base material plate, so that the surface of the wear-resisting plate is smooth after cladding processing is finished, the quality of the wear-resisting plate is not prone to being influenced by uneven recesses, and the production quality of the wear-resisting plate during cladding production is improved.

Description

technical field [0001] The invention relates to the technical field of production and processing of wear-resistant plates, in particular to a laser cladding process for wear-resistant plates and its auxiliary equipment. Background technique [0002] Double-metal clad wear-resistant steel plate is a plate product specially used for large-area wear conditions. It is made of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity. A plate product made of a wear-resistant layer with excellent abrasiveness. [0003] Because the bottom plate of the pusher in the coal yard often rubs against the material, the bottom plate is mostly made of wear-resistant plates. The wear-resistant plates for the bottom plate of the pusher in the coal yard are mostly made of laser cladding technology during production, but The existing wear-resistant plate for the bottom plate of the pusher adopts a pre-set laser cladding cladding process during laser cladding. When the iron...

[0003] Because the bottom plate of the pusher in the coal yard often rubs against the material, the bottom plate is mostly made of wear-resistant plates. The wear-resistant plates for the bottom plate of the pusher in the coal yard are mostly made of laser cladding technology during production, but The existing wear-resistant plate for the bottom plate of the pusher adopts a pre-set laser cladding cladding process during laser cladding. When the iron, cobalt, and nickel alloy powders are covered on the base plate There is a certain gap between the alloy powders, and a certain amount of air bubbles will be generated in the wear-resistant layer during laser cladding due to the gap, resulting in a certain amount of air bubbles in the wear-resistant layer of the wear-resistant plate produced by laser cladding, which affects The wear-resistant effect of the wear-resistant layer, and a certain amount of bubbles discharged during laser cladding will cause the upper surface of the wear-resistant layer to be uneven due to the lack of a certain amount of iron, cobalt, and nickel alloy powder with the size of the bubbles, affecting The quality of wear plate, therefore, in order to solve such problems, we propose a laser cladding process for wear plate and its auxiliary equipment
