I plant using the latest technology to produce national research institutions DFC? 300 type efficient poly slag agent is melting a new type of chemical additives in the casting process, is the latest generation product in the foundry industry slag process and have a good catch slag, in addition to slag and thermal insulation properties. Spreading on the surface of the molten metal is able to be expanded under high temperature made viscous active material, rapid adsorption of the gold in the molten slag and impurities and plastic crust is formed covering the surface of the molten, play polyethylene slag, Cleaner, purification effect of the melt. Improve the intrinsic quality of the castings to reduce waste, reduce energy consumption, shorten the operating cycle, improve the utilization rate of melting metal. Because of its low thermal conductivity, which can effectively play the insulating effect. The products are mainly used for cast steel, cast iron, ductile steel, alloy steel, stainless steel, special steel and non-ferrous metal melting and casting.
Second, the role and use:
, Slag and slag: Efficient Cleaner agent ladle, crucible furnace, electric furnace, reverberatory furnace. Artificial or gun evenly spreading on the surface of the melt, a little agitation to quickly gathered into the separation of slag and metal solution is easy to shell, stripped off the crust that you can get the pure solution, deducting castings gravel, and improve quality. Low cost, not burst splash, safe, reliable, easy to use. Sporadic slag for slag in the slag after casting ladle or furnace mouth, adding polyethylene slag agent, to form a strip floating dam, sticky block, eliminating the need for artificial slag, reduce labor intensity, improve labor efficiency.
Insulation properties: low thermal conductivity of the efficient polyethylene slag agent, in floating layer formed on the surface of the molten metal may prevent the solution of heat conduction and thermal radiation, and become good insulation layer. This subcontract or the need for intermediate parking longer metal solution is an excellent insulation covering agent.
3, environmental protection: efficient polyethylene slag agent of the molten metal, no pollution, no penetration, does not affect the mechanical properties of its chemical composition and casting. No smoke, dust and harmful gas pollution, cleaning up the environment, civilized production.
Dosage: efficient polyethylene slag agent is generally added amount is 1.5? 2.0kg / T metal solution, specifically based on the size of the melt temperature, where appropriate, increase or decrease the amount of melting metal impurity.
