Refractory spinel products used for proportioning material

Product: Sintered spinel

Color : Grey/ blue etc.

Usage: Refractory material

Common size: 1-2 2-4 4-6 mm etc.

Packing: 25/50 kg/ bag

Description

The two main methods for synthesizing spinel are sintering and electrofusion. Most spinel materials are made of high-purity synthetic alumina and chemical-grade magnesium oxide, which are sintered in a shaft kiln and fused in an electric arc furnace.

Advantages of Spinel

  • Wear resistance
  • High temperature resistance
  • Erosion resistance
  • Small thermal expansion coefficient
  • Good thermal stability

Application of Spinel

  • Proportioning material
  • Glass industry kiln
  • Castable
  • Cement rotary kiln
  • Steel making
  • Iron manufacturing
  • Refractory material
