Deslagging refining agent dfc-250

1、 Model: deslagging refining agent dfc-250.

2、 Specification: Powder

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).

4、 Dfc-250 type slag remover and refining agent is particle, green, environmental friendly and easy to operate. It is the only new generation product that can replace or even exceed several times the slag remover at present.  Slag removal, oxygen removal, nitrogen and oxygen removal, sulfur and phosphorus reduction, inclusion, oxide and sulfide removal, metal matrix purification, grain refinement, optimization of metallographic structure, rapid inoculation, stable reaction, no pollution of the refining agent on the metal penetration, avoid the formation of hard spots on the surface of the casting, prevent cutting during cutting, improve machinability, and maintain the temperature of the steel water Effect.

5、 Dfc-250 deslagging refining agent purpose:

*、 DFC-250
*Dfc-250 deslagging refining agent is widely used in smelting, smelting, remelting and casting of cast steel and iron-based metal: it is used for smelting of various cast steel and ferroalloy products.

*The refining agent is mainly used for slag removal, purification and refining of molten steel, molten iron and ferroalloy. The refining agent has the functions of degassing, nitrogen removal, oxygen removal, sulfur and phosphorus reduction, removal or dispersion of metal slag inclusions, metal matrix purification, grain refinement, metallographic structure optimization, metal performance improvement, temperature maintenance of molten steel, product quality improvement and "microalloying" Effect.

*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.

*Dfc-250 slag removal refining agent has the characteristics of "one agent and multiple effects". When purifying and refining liquid metal, it can remove nitrogen, oxygen, pores and pinholes, reduce sulfur and phosphorus, remove or disperse inclusions in liquid metal, purify metal matrix, refine grains, optimize metallographic structure, increase metal performance and improve product quality.

*/While refining molten steel and molten iron, the refining agent contains 17 rare earth elements and dozens of metal or non-metal elements in the formula, which can play the role of "microalloying" to maintain the temperature of molten steel, making it possible to realize "alloying" or "microalloying" of iron-based metals at low cost.

*The elongation of the grey cast iron test bar purified and refined by dfc-250 slag removal refining agent is 0.28%. It can be welded with low carbon steel electrode. After welding, the test bar has good cutting performance and welding strength, which breaks the two conclusions that "the extension of grey cast iron is zero" and "grey cast iron can only be welded with pure nickel or nickel base cast iron electrode" which are universally recognized by the global cast iron and casting industry.

6、 Application method of dfc-250 slag removal refining agent

*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 grains, optimize metallographic structure, increase metal performance and increase production Quality of products and the role of "microalloying" to maintain the temperature of molten steel
