Pre-Acting Henan steel refining slag present, most steel mills are commonly used by ladle refining technology to reduce gas inclusions, so just sleep homogenization, in order to achieve high-yield, high-quality, low-cost steel. Therefore, the ladle slag increasingly demanding. Therefore, the Company's technical staff on the production line has been extensive and meticulous research, multi-data collection, active collaboration with the German Metallurgy Association, the American Association of Engineers and other foreign mining and milling relevant academic institutions and relevant domestic institutions, research institutions, so that product quality steadily improved based on user feedback, the company produced the effect of refining agent has reached even better than the level of imported products. Such versatility steelmaking agent has the following characteristics. Pre-Acting refining slag which uses limestone (including CaO), magnesite (including MgO), dolomite (including CaO · MgO), witherite (including BaO) and fluorite (including CaF2) after sintering furnace melting in the sky from the system. This slag melting point is low, with the fastest speed melted shortening the molten steel in the refining package residence time, strengthen the smelting of conduct. This refining agent while liquidity is very good, to optimize the conditions for the desulfurization reaction kinetics, can achieve deep desulfurization. Ladle refining process, only for different types of steel slag system to select a different order to achieve the desired metallurgical results. Various types of slag system currently widely used in the world are for different metallurgical environments, different atmosphere, different kinds of steel to choice. Therefore, the composition range of pre-Acting volatile refining slag, alkalinity change is particularly evident, can vary from about 1.0 to 12; other elements of the changes can be from 0-40. Component of the pre-Acting refining slag are the following. (1) CaO CaO is an essential ingredient in the production of metallurgical slag, dephosphorization, desulfurization, with its vast source (natural limestone as raw materials, smelting significant effect, is blast furnace slag, converter slag, electric furnace slag and various Pre-Acting class refining slag main component. To ensure good desulfurization effect, require pre-Acting refining slag contains high free state CaO. (2) Al2O3 Al2O3 mainly from raw materials and deoxygenated product. It desulfurization affect two aspects: on the one hand, with the increase of the amount of Al2O3, the slag viscosity reduced, to promote the reaction of steel slag, in favor desulfurization; while on the other hand, it reduces the increase in Al2O3 activity, suppression desulfurization (3) SiO2. SiO2 mainly from impurities in raw materials (gangue) and deoxygenated product, with some fluxing action. However, increased content of oxygen, desulfurization were unfavorable (4) CaF2 CaF2 can significantly reduce the viscosity of the pre-Acting refining slag, so improve slag fluidity, increasing mass transfer is conducive to desulfurization, but it is too large, is not conducive to deoxidation, and the erosion of the lining is relatively fast. for foaming properties, its impact is twofold. On the one hand, CaF2 increasing the amount of the surface tension reduction, is conducive to slag foaming, but on the other hand, the viscosity of the slag decrease, not conducive to foaming, tension plays a leading role. (5) MgO pre-melting type refining slag in the slag MgO mainly from materials and refractories, slightly lower than its desulfurization capacity CaO (a) Product features a low melting point melting faster, shortening the refining time, reduce the power consumption of refined; 2, good liquidity, desulfurization and good ability to inclusion; 3 Use no flame, small dust, good security; 4, non-absorbent, dust, storage and transportation process will not degenerate; 5, submerged arc effect, reducing the arc of the lining of the burning erosion, improve package age . factory direct selling price, the price please contact us to welcome new and old customers call to discuss solemn promise:.!. to ensure the best product, best quality, lowest price, best service to thank new and old customers trust business principles: customer first, quality, variety, reasonable prices.
