1. Product introduction:

 

DFC-300 high-efficiency slag agglomerating agent produced by the latest technology of national scientific research institutes is a new chemical additive in smelting and casting process. It is the latest substitute product in slag removal process of foundry industry. It has good slag removal, slag removal and heat preservation performance. Spreading on the surface of molten metal is a kind of viscous active material which can expand and become viscous under the action of high temperature. It can quickly absorb the slag and impurities in the molten gold, and form a plastic slag shell covering the surface of molten metal. It has the effect of slag agglomeration, slag removal and liquid purification. Improve the internal quality of castings, reduce waste products, reduce energy consumption, shorten the operation cycle, and improve the utilization rate of smelting metal. Because of its low thermal conductivity, it can effectively play the role of thermal insulation. This product is mainly used for smelting and casting of cast steel, cast iron, spherical steel, alloy steel, stainless steel, special steel and non-ferrous metals.

 

2. Functions and methods of use:

 

1. Slag removal and slag retaining: High efficient slag removal agent can be used in pouring ladle, crucible boiler, electric furnace and reverberatory furnace. After being dispersed on the surface of molten liquid artificially and evenly, the slag shell which can be easily separated from the metal solution can be quickly assembled with a little agitation, and the pure solution can be obtained by removing the slag shell, which can reduce the sand inclusion in the castings and improve the quality of the castings. The utility model has the advantages of low cost, no explosion, no splash, safety and reliability, and is easy to use. If slag retaining is needed, slag agglomerating agent can be added at the pouring ladle or furnace mouth before slag removal and casting, forming strip floating dam, sticking sporadic slag, eliminating manual slag retaining, reducing labor intensity and improving labor efficiency. Adding this product to the surface of molten steel can not only adsorb impurities and purify molten steel, but also ensure that there are no impurities in molten steel, so as to prevent the inclusion of slag in sand mold with molten steel. This product is made of environment-friendly high-quality raw materials, granular, non-toxic, tasteless, strong adsorption, good laying, suitable viscosity, heat preservation and slagging ability.

 

2. Heat preservation performance: high-efficiency slag agglomerate has low thermal conductivity. Floating layer formed on the surface of molten metal can prevent heat conduction and radiation of solution and become a good heat preservation layer. This is an excellent thermal insulation covering agent for intermediate subcontracting or metal solution which needs to be parked for a long time.

 

3. Environmental protection: High-efficient slagging agent has no pollution and penetration to molten metal, and does not affect its chemical composition and mechanical properties of castings. Smoke-free, dust-free and harmful gas pollution, can purify the environment, civilized production.

 

4. Dosage: The general dosage of high-efficiency slagging agent is 15-20kg/T metal solution, which can be increased or decreased according to the size of molten area, temperature and impurity content of smelting metal.

 

5. Keeping: Keeping from dampness
