Silicon aluminum barium calcium

Weden Metal Co.,Limited | Updated: Jan 25, 2018


Calcium barium aluminum barium alloy barium alloy is the best deoxidizer, desulfurization agent, the oxygen in the steel to a minimum, while the formation of calcium, barium, silicon, aluminum complex oxide easily float from the molten steel, Pure molten steel to improve the impact resistance of steel and processing performance.

Production methods: 

First, silica, bauxite, coke mixed evenly, adding heat smelting furnace to produce silicon-aluminum alloy. Then add CaO and coke in batches to promote the formation of Si-Ca-Al. Then add barium ore and coke in batches to promote its formation of barium calcium aluminum alloy. General silicon calcium barium aluminum alloy composition: Si> 30%, Ca> 6%, Ba> 9%. Al> 8%.

Production to control Al2O3 / SiO2, CaO / BaO, (CaO ten BaO) / Sio2 ratio, and control the amount of coke addition.

Equipment parameters to choose a higher current and lower operating voltage, to have a very high circular power and high furnace power. Maintain the furnace reaction zone has a higher temperature. Always use the method of burning stew operation, and use plus CaO and BaO slag treatment, so that the exclusion of the furnace.

Such as large electric furnace in the production of calcium silicon barium, aluminum ingots can be hot-rolled production of calcium-aluminum barium aluminum alloy. However, this method does not produce calcium silicate barium aluminum ore with good economic effect.

Uses: Highly efficient deoxidizer is steel auxiliary material. It is suitable for a variety of steelmaking deoxidation, especially for converter steelmaking deoxygenation. Has a strong deoxy, desulfurization effect, can well improve the flow of molten steel to solve the nozzle junction problems. Reduce the gas in the steel and reduce the inclusion of molten steel.


The main producing areas are Inner Mongolia, Shaanxi, Shanxi and other provinces.
