Synthetic refining slag prices - Multifunction REFINING common types of refining slag refining slag from the chemical composition of view, based mainly CaO-CaF2, CaO-Al2O3-based, CaO-Al2O3-SiO2-based; refining slag from the main form of sintered type, pre-melt and mixed. Sintered refining slag refers to the particle size of the raw material by a certain percentage, and mixed, heated at less than the melting point of the raw material, the raw material sintered together and then crushed to a particle size after refining slag needed to use. Sintered refining slag composition is more uniform, stable, melting faster, but the cost is relatively increased, and as a result of sintering slag density, porosity and more easily lead to the refining process inhale. Pre-Acting refining slag after the raw material mixing means by a certain percentage, the use of high temperature in special equipment in case of a temperature above the melting point of the slag system of the raw material is melted into a liquid, then cooled broken for steelmaking slag refining. Pre-Acting purity high refining slag, uniform chemical composition, phase stability, low melting point, into slag speed, can significantly reduce the time and can be used directly in the refining ladle out the steel converter slag cleaning process, improve the cleanliness of molten steel . And not a small amount of fluorine-containing fluorine or reduce lining erosion, effectively reducing the fluorine pollution on the environment. Due to the structure of the pre-Acting refining slag dense, non-absorbent, easy storage and transportation, warehousing, not powder, non-volatile, can significantly reduce the steel plant dust pollution, but higher production costs. Refining slag characteristics: refining slag has a chemical composition uniformity, low melting point, melting speed, lower power consumption of refined shorten refining time, etc., more and more emphasis on iron and steel enterprises, is currently one of 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 happen and ladle lining erosion; compact structure, easy to transport, storage; the product itself matter phase stability, into slag fast, and significantly reduce dust pollution mills. Refining slag makes extensive use of steel companies currently rely on a change in the past refining high alkaline materials, steel slag mix out of the furnace desulfurization production process, greatly improve the efficiency of steel production, improve the quality and performance of finished steel . Refining slag use: Before tapping into the ladle refining slag, because between the molten steel and molten slag refining vigorous stirring into ladle from the top, is rapidly melting and refining slag in the molten steel, then gather float. Because of the strong reduction refining slag, it has a strong deoxy desulfurization capacity, can play off the oxygen function molten sulfur impurities in the molten steel mixing process. Currently refining slag desulfurization capacity can reach more than 85%, which is very good steel additives. Factory direct selling price, the price please contact us.
