Problems solved by technology

It has gradually developed from single deoxidation with aluminum to binary, ternary and multi-component composite deoxidized alloys, but these products can only play a role in deoxidation, and the price is relatively high. Phosphorus, which affects the quality of steel
[0003] Silicon-barium alloy is well known as a deoxidizer, although it has a fairly good deoxidation ability, it still cannot meet the further requirements for the oxygen content of molten steel
In addition, the desulfurization ability of existing silicon-barium alloys is obviously insufficient
At present, the published Chinese invention patent application No. 99109706.8 provides that the silicon-barium-magnesium-iron alloy used as a deoxidizer for steelmaking contains 2 to 8% aluminum, which requires aluminum-free steel types and acid-melted aluminum in steel for smelting. It is unfavorable for steel grades with very low content and strict

Abstract

A SiBaSrCaMgFe alloy used as deoxidant in smelting steel contains Si (40-60 wt.%), Ba (10-28), Sr (1-8), Ca (1-15), Mg (5-20) and Fe (rest). Its advantages are high deoxidizing power, sure desulfurizing effect and low cost.

Description

technical field [0001] The invention relates to a ferroalloy used as a steelmaking deoxidizer, in particular to a silicon-barium-strontium-calcium-magnesium-iron alloy used as a steelmaking deoxidizer, which is a supplement to existing ferroalloy varieties and belongs to the technical field of steelmaking. Background technique [0002] In recent years, the deoxidizers used for making killed steel have developed rapidly and have good effects. It has gradually developed from single deoxidation with aluminum to binary, ternary and multi-component composite deoxidized alloys, but these products can only play a role in deoxidation, and the price is high. In addition, although the molten steel for steelmaking still has a certain amount of sulfur, Phosphorus, thus affecting the quality of steel. [0003] Silicon-barium alloy is known as a deoxidizer, although it has a fairly good deoxidation ability, it still cannot meet the further requirements for the oxygen content of molten st...
