Abstract

The invention discloses a method for preparing silicon-calcium-barium-aluminum alloys from ore raw materials, and relates to the technical field of multi-element alloy preparation, including: S1: silica, lime, barium ore, bauxite, semi-coke, fluorite, stibnite, stibnite The bismuth ore and lead-zinc slag are cleaned and crushed; S2: Mix the crushed silica, lime, barium ore, bauxite, semi-coke, stibnite, and bismuthite in proportion, and add the mixture to the pre- Smelting in a hot submerged arc furnace, feeding once every 25 to 40 minutes; S3: adding fluorite to the furnace 20 to 30 minutes before the smelted alloy is released; when the furnace temperature is higher than 1780°C, add lead and zinc slag to reduce the furnace temperature, The silicon-calcium-barium-aluminum alloy can be obtained after 2.5-4 hours of normal circulation smelting. The silicon-calcium-barium-aluminum alloy prepared by the invention has excellent mechanical properties, high hardness, and good wear resistance; good deoxidation and desulfurization capabilities, and can be used as a deoxidizer and desulfurizer for steelmaking processes, effectively improving the quality of steel .

Description

technical field

[0001] The invention belongs to the technical field of multi-element alloy preparation, and in particular relates to a method for preparing silicon-calcium-barium-aluminum alloy with ore raw materials. Background technique

[0002] With the continuous advancement of metallurgical technology and the increasing requirements of the market for the quality of steel products, some special steel grades have very strict requirements on the quantity and form of non-metallic inclusions in steel. Experiments show that when the mass fraction of oxygen in steel is changed from 30×10 -6 Reduced to 10×10 -6 When it is less than 30 times, its contact fatigue life can be increased by nearly 30 times, which greatly improves the performance of steel. Therefore, how to reduce the oxygen content in steel and improve the purity of steel is particularly important.

[0003] At present, the deoxidation methods used in industrial production mainly include precipitation deoxidation,...
