Preparation method of high-strength stainless steel flux-cored wire

Abstract

The invention relates to a preparation method of a high-strength stainless steel flux-cored wire. The preparation method mainly comprises the following steps of raw material preparation, wire forming, drawing operation, straightening and dry wiping, oil coating and packaging and the like, and used flux-cored wire dry wiping equipment comprises an operation table, a dry wiping unit, a straightening unit, a water washing unit and a drying unit. The method can solve the following problems existing during dust removal treatment of an existing high-strength stainless steel flux-cored wire: a, the dust removal efficiency of the flux-cored wire is affected due to the fact that the time for replacing dry wiping cloth of existing dust removal equipment for the flux-cored wire is long, and wire drawing powder on the surface of the flux-cored wire is not completely wiped and needs to be wiped again, so that the dust removal efficiency of the flux-cored wire is affected; and b, after the flux-cored wire is subjected to water washing by the existing dust removal equipment for the flux-cored wire, residual water on the surface of the flux-cored wire cannot be completely cleaned, so that the oiling quality of the flux-cored wire is influenced, and the production quality of the flux-cored wire is reduced.

Description

technical field [0001] The invention relates to the technical field of welding material production and manufacturing, in particular to a preparation method of high-strength stainless steel flux-cored welding wire. Background technique [0002] High-strength stainless steel flux-cored wire is made of low-carbon steel or low-alloy steel with good plasticity. The manufacturing method is to first roll the steel strip into a U-shaped section shape, then add the solder powder prepared according to the dosage to the U-shaped steel strip, roll it tightly with a rolling mill, and finally make flux cores of different specifications by drawing. Welding wire, after drawing the flux-cored wire, it is difficult to remove the wire-drawing powder on the surface of the flux-cored wire. The appearance of the dirty flux-cored wire is not only poor, but also the quality of the flux-cored wire will be affected, so it is necessary to clean the flux-cored wire The surface of the welding wire is d...

Problems solved by technology

The manufacturing method is to first roll the steel strip into a U-shaped section shape, then add the solder powder prepared according to the dosage to the U-shaped steel strip, roll it tightly with a rolling mill, and finally make flux cores of different specifications by drawing. Welding wire, after drawing the flux-cored wire, it is difficult to remove the wire-drawing powder on the surface of the flux-cored wire. The appearance of the dirty flux-cored wire is not only poor, but also the quality of the flux-cored wire will be affected, so it is necessary to clean the flux-cored wire Dust removal treatment on the surface of welding wire

[0003] Yet the existing high-strength stainless steel flux-cored wire has the following problems in the dust removal process, a, the existing flux-cored wire dust removal equipment takes a long time to replace the dry wipe, which affects the dust removal efficiency of the flux-cored wire, and is harmful to the flux core The wire drawing powder on the surface of the welding wire is not completely wiped, and it needs to be wiped again, which reduces the dust removal efficiency of the flux cored wire; b. The existing flux cored wire dust removal equipment cannot wash the flux cored wire after washing. The water is completely cleaned, which affects the oiling quality of the flux-cored welding wire and reduces the production quality of the flux-cored welding wire
