Refining molten slag synthetic premelted sintering refining slag steel copper slagProduct DescriptionDescription of Refining Slag:The main components of the refining slag are CaAl2O4, Al2O3, SiO2, CaF2, MgO, etc. These metal ions are combined into CaO-CaF2 groups, CaO-Al2O3 groups, and CaO-Al2O3-SiO2 groups to form a composite material which is called refining slag.Based on different forms of refining slag, there are sintered refining slag, premelted refining slag and mixed refining slag.(1) Mixed / synthetic refining slagMixed refining slag is a kind of refining slag that directly mixes raw materials with a certain proportion and particle size manually or mechanically, Or added to the steel-making furnace directly according to the proportion of raw materials, It has the characteristics of simple method and flexible operation, but has slow melting speed and uneven composition.(2) Sintered refining slagCompared with the mixed type, the sintered refining slag is more uniform and stable, and the melting speed is faster, but the cost is relatively increased, and due to the smaller density of the sinter and the larger number of pores, it is easy to cause suction in the refining process.(3) Premelted refining slagPremelted refining slag is the refining slag used for steel-making. After mixing raw materials in proportion, and then melt the raw materials at higher temperature than the melting point of the slag system, crush the slag after cooling, we can finally get the premelted refining slag..Its purity is high, the chemical composition is uniform, the phase is stable, the melting point is low, and the speed of slag formation is fast. It can greatly shorten the refining time and can be directly used in the slag washing process of the converter ladle tapping process to improve the cleanliness of the molten steel.And what is more, no fluorine or a small amount of fluorine can reduce lining erosion, effectively reduce the pollution of fluorine to the environment.Due to the compact structure of the premelted refining slag, it does not absorb water, which is convenient for storage,transportation and storage, and also not powdered or volatile. It can significantly reduce dust pollution in iron and steel plants, but the production cost is higher.Characteristics of Refining Slag:(1) Rapid slag formation greatly improves the kinetic conditions of the chemical reaction in the molten pool during refining,accelerates the reduction reaction, and thus shortens the refining time.(2) It has strong reducibility, deoxidation and desulfurization to remove harmful components in the molten steel, and has the ability to trap non-metallic inclusions in the steel, so as to achieve the purpose of smelting clean steel.(3) It can significantly reduce power consumption, electrode consumption, refractory consumption, and the consumption of some expensive reducing agents such as aluminum, silicon-calcium alloy, etc., and can also reduce the overall production cost in the refining process to a certain extent.Specification

Application of Refined Slag:Put the refining slag into the ladle before tapping, because the molten steel flows into the ladle from the upper layer, it is the vigorous stirring between the molten steel and the refining slag, and the refining slag quickly melts in the molten steel, and then gathers and floats. Because of the strong reducibility of refining slag, it has a strong deoxidation and desulfurization ability, which can play the role of removing oxygen and sulfur impurities in molten steel during the mixing process of molten steel.
Packaging :1. Packing material and unit weight can be customized according to user's needs.2. Waterproof, rain-proof and moisture-proof measures should be taken during storage and transportation.
