refractory refractory brick High-Alumina Brick High temperature high refractoriness refractory materials Corundum

Product Description

Corundum products and synthetic corundum products are characterized by excellent thermal shock resistance, resistance to corrosion, erosion, and spalling. As a result, they are high-performance refractory materials widely used in glass furnaces, cement kilns, heaters, molten steel ladles, non-ferrous metallurgical furnaces, and furnaces in the chemical engineering industry.

Titanium corundum orifice rings and titanium rings are used as complete sets with spout feeders in glass furnaces. They are characterized by excellent resistance to corrosion and erosion by molten glass.

Specifications ：Zero expansion silica brick(fused silica brick)

Size:230*114*65/75mm
