Wear-resisting plate surfacing manufacturing method

Abstract

The invention relates to the technical field of surfacing, in particular to a surfacing manufacturing method for a wear-resisting plate. The method comprises a transmission mechanism used for driving transmission and an electric arc welding surfacing device arranged on the transmission mechanism, and specifically comprises the following steps that S1, paint is mixed, graphite powder and a water glass solution are mixed, the content of the water glass solution is about 0.1%-10% of the weight of the graphite powder, and carbonate is added for mixing; s2, coating is conducted, specifically, a steel plate base material is coated with the mixed graphite mixed liquid, and a graphite coating is formed; s3, drying: drying the coated graphite mixed solution to remove moisture of water glass in the graphite coating; s4, material distribution is conducted, specifically, the dried steel plate base material is placed on a conveying mechanism and conveyed through cooperation of the conveying mechanism; and S5, surfacing is conducted, specifically, surfacing is conducted through a flux-cored wire, and the wear-resisting plate is manufactured. The method has the beneficial effects that excessive oxidation at high temperature is avoided, the burning loss of alloy elements is reduced, and the space for adding and adjusting other alloy elements is increased.

Description

technical field [0001] The invention relates to the technical field of surfacing welding, in particular to a method for manufacturing wear-resistant plate surfacing welding. Background technique [0002] The use of arc welding surfacing welding methods, including open arc welding and submerged arc welding, is the main production method of surfacing welding composite wear-resistant plates that are common in industry at present. The production method is to combine high carbon and high chromium through the arc welding surfacing process The alloy material is surfacing on the surface of the steel plate to improve its wear resistance. [0003] During the welding process, the high temperature of the arc can cause the welding wire to melt to produce a metallurgical process. For high-carbon and high-chromium alloy welding wire, the carbon in it will be oxidized into carbon dioxide to generate a protective atmosphere to avoid excessive oxidation of the molten pool and affect the surfa...

Problems solved by technology

[0005] However, due to the limited powder filling ratio of the flux-cored wire and the low density of the graphite powder that must be added, it will occupy the powder filling space of the flux-cored wire and reduce the amount of other metal powders that can be added, making the range of alloys that can be designed for the flux-cored wire The production is limited, so it is necessary to design a wear-resistant plate surfacing manufacturing method to solve the above problems
