The Company adopts the aluminum ash multi-stage screening and efficient aluminum extraction technology to fully recover the metal aluminum in the aluminum alloy oxide slag waste resources generated in the production process of the aluminum alloy casting industry. The proposed metal aluminum can be returned to the aluminum alloy casting industry for direct use as raw materials, realizing the original recycling of aluminum alloy resources, saving mineral resources and reducing environmental pollution caused by mineral development.

Calcium aluminate refining slag is mainly composed of CaO-Al2O3. Calcium aluminate sintering refining slag is added to ladle refining processes such as converter and electric furnace, which can melt rapidly and increase the fluidity of molten steel. There is little dust in the process of putting, and F ions are not produced. Proper CaO-Al2O3 composition ratio can reasonably deoxidize, desulfurize and remove impurities from molten steel. In use, the submerged arc has a good effect, reducing the burning of the arc on the stove, and increasing the ladle age can realize the functions of fluorine free steelmaking, reducing the erosion of the furnace lining, improving the product yield, reducing the production cost, and reducing the environmental pollution. This product is widely used in large and medium-sized steel plants in Hebei, Shandong, Jiangsu, Hubei, etc.

Proppant refers to natural sand or artificial high-strength ceramic particles with a certain size and grading. Ceramsite proppant is made from bauxite by powder granulation and sintering. It is characterized by high temperature resistance, high pressure resistance, corrosion resistance, high strength, high conductivity, low density and low crushing rate, and is most widely used. Coating resin on the surface of sand or ceramsite can further improve the strength and conductivity of proppant. Proppant is the key material for fracturing construction.

It has good water purification effect, fast water purification speed, weak acid pH, inorganic, high safety, no secondary pollution, and is a green environmental protection product. With natural materials with adsorption capacity as raw materials, it has a strong purification effect and can remove heavy metals from water. The treated raw water is not affected by water temperature and pH value, and has a wide range of uses. The treated water has high transparency and can be reused.
