Embodiment 1

[0014] The H08A cold-rolled steel strip with a width of 15mm and a thickness of 0.4mm enters the tube wire rolling mill and then passes through 2-3 rolls to form a U-shaped section.

[0015] Take the mass percentage as C5.65; Cr22.20; Mn0.72; Si0.36; Co0.79; Mo2.57; B0.12; , to obtain the drug core powder for subsequent use.

[0016] The drug core powder mixed uniformly by the V-shaped mixer is directly injected into the U-shaped H08A cold-rolled steel belt groove, the filling rate is 47wt%, and the U-shaped groove is mechanically occluded according to the seam in the length direction of the steel belt, so that the drug powder is wrapped in it; The powdered welding wire is rolled through 7 passes to form a closed tubular welding wire, and then passed through a wire drawing die with a drawing amount of 0.2 to 0.3 per pass, drawn and reduced one by one, and finally a surfacing flux with a diameter of 2.8mm is obtained cored wire.

Abstract

An amorphous structured surfacing flux-cored welding wire, which is made of cold-rolled strip wrapped alloy powder through a wire drawing die, drawn one by one, and reduced in diameter. It is characterized in that it is prepared from the following raw materials in mass percentage: C5.41 -6.10, Cr21.38-24.90 Mn0.64-1.44, Si0.32-0.90Co0.80-1.58, Mo2.58-5.13 B0.12-0.25, Y0.26-0.51Fe balance. Compared with the prior art, the present invention has the following outstanding advantages: 1. Compared with the amorphous coating made by thermal spraying, the layer of amorphous structured material made by surfacing welding is thick, and can be superimposed and welded to several millimeters, and the coating and the base material The metallurgical combination further broadens the application of amorphous materials; 2. Compared with ordinary surfacing layers, it improves its amorphous structure and endows the surfacing layer with the characteristics of amorphous alloy materials.

Description

technical field [0001] The invention belongs to the field of surfacing welding in material processing engineering, and in particular relates to an amorphous structured surfacing welding flux-cored welding wire. Background technique [0002] Amorphous alloy material is a new type of advanced metal material with special properties synthesized by metallurgical technology that has emerged in recent years. Compared with static alloys, it not only has extremely high strength, hardness, toughness, wear resistance, corrosion resistance and High resistivity, but also exhibits excellent soft magnetism, superconductivity, low magnetic loss and other characteristics, it is these special physical, chemical and mechanical properties that endow amorphous materials with potential applications in various industries. [0003] The formation theory and preparation process of bulk amorphous alloy materials are not yet mature, and the size of bulk amorphous alloys is difficult to meet the size re...
