The molten steel protective slag must have the following functions: 1. thermal insulation; 2. air isolation to prevent secondary oxidation of the molten steel; 3. purification of the molten steel; 4. adsorption of inclusions in the molten steel; 4. lubrication of the billet shell and improvement of solidification heat transfer. The performance of protective slag directly affects the surface quality and internal quality of steel billets, that is, the qualification rate of steel billets
According to the type of steel cast, the cross-section of the billet, and the casting speed, the corresponding protective slag is selected. The composition of the protective slag is reasonable and stable to meet the quality requirements of the billet
The types of steel billets include square billets, thin slabs, conventional slabs, etc. Our company produces and supplies multiple grades of protective slag, which meet the requirements of different types of steel billets and meet the requirements of low-carbon and medium carbon steel billets. The selection and proportion of raw materials are scientific and reasonable, achieving the functions that protective slag should have, and the use effect is good.
