Economical welding wire steel bzj60-ti and its production and preparation method

Abstract

The invention relates to welding wire steel BZJ60-Ti and its production and preparation method, which relate to the field of metallurgical manufacturing technology, and in particular to BZJ60-Ti steel for manufacturing economical welding wire and the preparation method of the BZJ60-Ti steel. The welding wire steel BZJ60‑Ti of the present invention includes the following chemical components: C: 0.50% to 0.80%; Si: 0.42% to 0.60%; Mn: 1.42% to 1.60%; Cr: 0.35% to 0.45%; P: ≤0.015%; S: 0.008% to 0.015%; V: 0.03% to 0.05%; Ti: 0.080% to 0.11%; B: 0.0030 to 0.005%. The production and preparation method includes the following steps: converter smelting, ladle alloying, static argon blowing, LF furnace refining, continuous casting, heating process, and rolling process. The technical solution of the present invention solves the problem of the existing BZJ60‑Ti welding wire steel in the prior art with high titanium content, poor castability, large fluctuations in the liquid level during the casting process, and poor quality of the slab resulting in rolling scabs and user pulling. In the case of broken wire, the produced welding wire will spatter during welding, which will seriously affect the welding quality and effect.

Description

technical field [0001] The welding wire steel BZJ60-Ti and the production and preparation method thereof of the invention relate to the technical field of metallurgical manufacturing, in particular to the BZJ60-Ti steel for manufacturing economical welding wire and the preparation method of the BZJ60-Ti steel. Background technique [0002] At present, there are many kinds of welding wire steel on the market. Some varieties of welding wire (such as BZJ60-Ti) have high titanium content, poor pourability of molten steel, large fluctuation of liquid level during pouring, and poor quality of casting billet, which leads to rolling scarring and users. In addition, the phenomenon of welding splashes often occurs during welding, which seriously affects the welding quality and efficiency. [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 production efficiency and energy sav...
