This information will be carefully reviewed and used to determine the appropriate grade of electrode for the particular application. Our goal is to supply the most cost effective electrode for your operation, an electrode that will run without breakage and offer efficiency in production.
We focus on continual product development, improvement, thoughtful services and technical support. Professional technicians will visit customers regularly; Providing after-sales support; Rongxing has proven to be a reliable and qualified supplier of superior graphite and carbon products to various international operations.
premelted refining slag steel slag
Premelted refining slag is a necessary additive to form basic refining slag used in secondary metallurgy to desulphurise and refine steel.
Refining slag series are important material that is applied in the ladle furnace refining process, to purify the molten iron by deep desulfuration and deoxygenation. The refining slag series include pre-melted refining slag, sintered refining slag and synthetic refining slag, its main content is CaO and Al2O3.

Product advantages
1,Pre-melted refining slag has sufficient conditions for metallurgical requirements such as stable physical and chemical properties, low melting point and low viscosity.
2,The pre-melted refining slag does not contain F, H, N, C and other impurities, which can effectively improve the quality of refined steel;
3,the content of MgO is reasonable and stable, and will not corrode the furnace lining and ladle;
4,the structure of the refined slag is dense and can be stored or stored Transportation is very convenient;
5,the cost is stable and the slag formation speed is fast, which can reduce dust pollution during the refining process of the steel plant.
In addition, practice has proved that the deoxidation, desulfurization and impurity adsorption functions of the pre-melted refining slag produced by our plant are relatively better than those of its counterparts, and the unit consumption is reduced by 20%.
