Nonferrous Metals Melting Industry

With the rapid development of science and technology, the nonferrous metal industry is becoming a basic industry to progress agriculture, industrial, and modernizing defense. From exploring space to watching TV, nonferrous affect our lives in every aspect. As a supplier of refractory materials, Kerui will find more green refractory materials for the nonferrous metals industry.

Introduction of the Nonferrous Metals Melting Industry

High-temperature equipment in the nonferrous metals industry mainly melts copper, nickel, lead, and other metals. The nonferrous metals industry uses lots of high-temperature equipment, including blast furnaces, flash furnaces, reflection furnaces, Nolanda furnaces, converters, anode furnaces, lead zinc enclosed blast furnaces, and vertical thank lead zinc distillation furnaces.

Blast furnace and flash furnace add powdery sulfide to melt copper and nickel. In the production process, these substances will release abounds of heat and chemical gas. In this situation, the dense refractory bricks usually choose high refractoriness and good chemical resistance. They use magnesia chrome bricks and high alumina bricks as the linings.

Refection furnaces mainly process fine materials. In the reaction process, these materials will release SO2 gas. So they use silica bricks, magnesia bricks, magnesia chrome bricks, and magnesia alumina bricks.

Nolanda furnaces have a cooling zone, so they use refractory brick with good thermal shock resistance. Like the other furnaces, there is SO2 gas in the Nolanda furnaces. So they can also use magnesia chrome bricks.

Converter furnaces need the brick with wear resistance, good thermal shock resistance, and high refractoriness. The magnesia chrome bricks will form a protective film that does not peel off. It is an ideal material.

Anode furnaces use the fuse rebound magnesia chrome bricks and clay bricks as the linings. They can greatly improve the high-temperature equipment life cycle.

Lead zinc enclosed blast furnaces and vertical thank lead zinc distillation furnaces use coke to melt the zinc. So they use high alumina bricks as the body linings, and magnesia chrome bricks as the hearth lining. In the cooling zone, they use silicon carbide bricks.


As we discussed above, we know magnesia chrome brick is an ideal refractory material that can widely be used for much nonferrous metal melting equipment. Kerui Refractory produces high-quality magnesia chrome bricks for customers. Our product has passed the international institution inspection. You can check the certificates on our page.
