Synthetic refining slag manufacturers _ kind commonly used calcium REFINING suppliers from the chemical composition of refining slag refining slag of view, mainly CaO-CaF2-based, CaO-Al2O3-based, CaO-Al2O3-SiO2-based; from the shape of the main refinery slag There sintered pre-melt and mixed. Sintered refining slag refers to the raw materials and particle size by a certain percentage mixture was heated at less than the melting point of the material, the raw material sintered together and then broken up into refining slag after the particle size required for use. Sintered refining slag composition is more uniform and stable, melting faster, but the cost is relatively increased, and since the sintering slag density, porosity more easily lead refining process inhale. Pre-Acting means after refining slag by mixing raw materials, high temperature in special equipment at temperatures above the melting temperature of the slag-based raw materials melt into liquid, then cooled broken for steelmaking slag refining. Pre-Acting purity refining slag is high, even the chemical composition, phase stability, low melting point, slagging speed, can significantly reduce refining time and can be used directly in the process of converter steel slag ladle out the wash, improve the cleanliness of molten steel . And not a small amount of fluorine or fluorine, reducing lining erosion, effectively reducing the fluorine pollution of the environment. Because of the structure of the pre-melt type refining slag dense, non-absorbent, easy storage and transportation, warehousing, not powder, non-volatile, can significantly reduce the steel mill dust pollution, but higher production costs. REFINING Features: refining slag has a chemical composition uniformity, low melting point, melting speed, lower power consumption of refined, shorten the refining time, etc., more and more attention steel companies, is the most important steel-making additives. I plant the refining slag has no fluorine, hydrogen, nitrogen, carbon and other impurities, will help improve the quality of the production of steel; non-absorbent, will not occur on the lining and ladle erosion; compact structure, easy to transport, storage; product itself was phase stability, into slag fast, significantly reducing mill dust pollution. Refining slag makes extensive use of steel-making enterprises changed in the past now rely on high refining base material, mixed with a steel slag, furnace desulfurization production process, greatly improve the efficiency of steel production, improve the quality and performance of finished steel . REFINING use: Before tapping into the ladle refining slag, because between the molten steel and molten slag refining vigorous stirring from the top into ladle, is, and the rapid melting refining slag in molten steel, then gather float. Because of the strong reduction refining slag, it has a strong deoxy desulfurization capability, can play off function molten steel oxygen sulfur impurities in the molten steel mixing process. Currently refining slag desulfurization capacity can reach more than 85%, it is a very good steel additive. Factory direct selling price, the price please contact us.
