Calcium Aluminate Refining Slag

【Product Introduction】

Calcium aluminate refining slag is an efficient steelmaking impurity removal material with high-purity calcium oxide and aluminum oxide as the main components. It is widely used in the molten steel refining process to improve the purity and yield of steel.

【Physical and Chemical Indicators】

【Product Features】

High Desulfurization Efficiency
The CaO content in the refined slag is as high as 54%, which reacts quickly with S in the molten steel, has higher desulfurization efficiency, and less reaction residue.

Dense And Durable Structure
Calcium aluminate refining slag forms a dense glass phase structure through high-temperature sintering + melt cooling process, with good thermal shock resistance and not easy to break. It has strong cycle stability in the refining furnace, and the average service life is more than 30% higher than that of ordinary calcium aluminate slag.

【Frequently Asked Questions】

Q: What is the working principle of calcium aluminate refining slag?
A: Calcium aluminate refining slag reacts with impurities such as sulfur and oxygen in molten steel to generate a slag phase that is easy to float, thereby reducing the content of harmful elements in steel.

Q: In which steelmaking links is it mainly used?
A: It is mainly used in the post-furnace refining link of converter steelmaking and electric arc furnace steelmaking, as well as molten steel purification during continuous casting.

Q: What are the advantages of calcium aluminate refining slag compared with other refined slags?
A: Compared with other refined slags, it has high desulfurization efficiency, fast reaction speed, low melting point, and is easy to mix and react with molten steel.

Q: What issues should be paid attention to when storing this product?
A: When storing, it should be placed in a dry and ventilated warehouse to avoid moisture and agglomeration, and away from fire and corrosive substances.

Q: Are there any special requirements during transportation?
A: During transportation, the products must be packed in sealed bags or sealed containers to prevent them from getting wet and rainy. During loading and unloading, avoid severe impact that may cause damage to the packaging.
