Rebonded Magnesia refractory refractory brick High temperature high refractoriness refractory materials Magnesia

Product Description

Rebonded magnesia brick is a type of magnesia-chrome refractory brick mainly produced from fused magnesia-chrome clinker as the primary raw material. It is manufactured through crushing, proportioning, mixing, forming, and high-temperature firing.

This material belongs to the rebonded direct-bonded refractory category, characterized by a dense microstructure, high high-temperature strength, and excellent resistance to slag corrosion.

Feature

• Dense and compact structure

• High high-temperature strength and good structural stability

• Excellent resistance to slag corrosion and penetration

• Long service life under severe high-temperature conditions

Typical Application

Glass Industry: Key parts of glass melting furnaces, horseshoe flame furnaces, regenerators, melting tanks, throat passages, and furnace bottoms.
Non-ferrous Metallurgy: High-temperature and severe corrosion zones of copper smelting flash furnaces, converters, reverberatory furnaces, and nickel smelting furnaces.
Other High-Temperature Furnaces: Various smelting furnaces and chemical kilns operating under severe erosion and high-temperature load conditions.
