Economical welding wire steel BZJ60-Ti and production and preparation method thereof

Abstract

The invention discloses economical welding wire steel BZJ60-Ti and a production and preparation method thereof, and relates to the technical field of metallurgical manufacturing, in particular to BZJ60-Ti steel for manufacturing economical welding wires and a preparation method of the BZJ60-Ti steel. The economical welding wire steel BZJ60-Ti disclosed by the invention comprises the following chemical components: 0.50-0.80% of C; si: 0.42% to 0.60%; mn: 1.42% to 1.60%; 0.35% to 0.45% of Cr; less than or equal to 0.015% of P; s: 0.008% to 0.015%; 0.03% to 0.05% of V; 0.080% to 0.11% of Ti; and B: 0.0030% to 0.005%. The production and preparation method comprises the following steps of converter smelting, steel ladle alloying, static argon blowing, LF furnace refining, continuous casting, a heating process and a rolling process. According to the technical scheme, the problems that in the prior art, existing BZJ60-Ti welding wire steel is high in titanium content, poor in castability, large in liquid level fluctuation in the casting process and poor in casting blank quality, consequently, rolling scabbing and user drawing wire breakage are caused, the produced welding wire is splashed in the welding process, and the welding quality and effect are seriously affected are solved.

Description

technical field [0001] The invention relates to economical welding wire steel BZJ60-Ti and a production and preparation method thereof, and relates to the technical field of metallurgical manufacturing, in particular to BZJ60-Ti steel for manufacturing economical welding wire and a preparation method of the BZJ60-Ti steel. Background technique [0002] At present, there are many kinds of welding wire steels on the market. Some welding wire varieties (such as BZJ60-Ti) have high titanium content, poor castability of molten steel, large fluctuations in the liquid level during the pouring process, and poor quality of the billet, resulting in rolling scarring and user failure. In addition, the phenomenon of welding spatter often occurs during welding, which seriously affects the quality and efficiency of welding. [0003] BZJ60-Ti welding wire steel is used for drawing CO 2 Gas shielded welding wire. CO 2 Gas shielded welding has the advantages of low welding cost, high produ...

AI Technical Summary

Problems solved by technology

[0005] According to the above prior art, the existing BZJ60-Ti welding wire steel has high titanium content, poor castability, large fluctuations in the liquid level during the casting process, and poor quality of the billet, resulting in rolling scabs and broken wires when the user draws. Spatter phenomenon occurs during welding of the out-flowing welding wire, which seriously affects technical problems such as welding quality and effect, and an economical welding wire steel BZJ60-Ti and its production and preparation method are provided
