3、 This product is a patented product for smelting industry, and foundry industry is the basis for developing machinery, national defense, aviation and other industries in various countries. At present, for the products of casting and smelting in our country, the materials used in the purification of steel and molten iron can only remove the scum on the surface of steel and molten iron, while the impurities in the steel and molten iron, such as nitrogen and oxygen produced by waste, furnace body, air and other humid gases, such as phosphorus, oxide, sulfide, pore, pinhole slag and other harmful gases, cannot be removed. This affects the quality of the product. It also causes porosity, pinhole and slag inclusion, which affects the quality of castings. For this reason, based on Harbin Institute of technology, we have developed a new generation of dfc-250 slag removal refining agent. Purification (cast steel, cast iron).

*Dfc-250 type slag remover and refiner mainly involves the purification and refining of molten steel and molten iron. There are many existing metal purifiers, deoxidizers, slag removers and other products with single effect. Therefore, our factory has cooperated with Harbin Institute of technology to develop a kind of natural mineral powder which can be directly used in the smelting, smelting, remelting and casting of liquid metal, so as to realize the goal of "one The multi-purpose "and" one multi effect "of the agent give full play to the multi effect and superposition effect of 17 rare earth elements and dozens of metal or non-metal elements contained in the unique formula of the refining agent. When purifying and refining the liquid metal, it can remove nitrogen and oxygen, remove pores and pinholes, reduce sulfur and phosphorus, remove or disperse inclusions in the liquid metal, and purify the metal matrix and fineness At the same time, all the refined materials or products become "microalloyed" materials or products, which makes the "thin-walled" and "lightweight" mechanism manufacturing revolution possible.

*The addition amount is 0.5% - 1% of the weight of the liquid metal. The traditional "bottom punching method" principle and function is to melt the liquid metal with its own heat to produce chemical and physical reactions. It can remove nitrogen and oxygen, reduce sulfur and phosphorus, remove inclusions, purify the metal matrix, refine the grain, optimize the metallographic structure, increase the metal performance, and improve the product Quality, and make its "microalloying" to maintain the role of water temperature.
