Product Description

Product DescriptionRefining slag refers to the technology used after mixing raw materials in a certain proportion and particle size, heating them below the melting point of the raw materials, sintering the raw materials together, and then crushing them into particle sizes. The main components are CaO-CaF2 base, CaO-Al2O3 base, and CaO-Al2O3-SiO2 base. The form of refining slag mainly includes sintered type, pre-melted type and mixed type.Pre-melted refining slag refers to the refining slag used for steelmaking after mixing the raw materials in a certain proportion, using high temperature in a special equipment to melt the raw materials into a liquid state at a temperature higher than the melting point of the slag system, and then cooling and crushing. The pre-melted refining slag has high purity, uniform chemical composition, stable phase, low melting point and fast slag formation speed, which can greatly shorten the refining time and can be directly used for slag washing in the converter ladle tapping process to improve the cleanliness of molten steel . And it does not contain fluorine or a small amount of fluorine, which reduces the corrosion of the furnace lining and effectively reduces the pollution of fluorine to the environment. Due to the compact structure of the pre-melted refining slag, it does not absorb water, is convenient for storage, transportation and storage, does not pulverize, and is not volatile, which can significantly reduce dust pollution in steel plants, but the production cost is high.Product Parameters
