China 8 Year Exporter Magnesite Refractory Bricks - High quality sintered refractory corundum mullite brick – Rongsheng factory and manufacturers | Rongsheng Detail:

Corundum mullite brick is a kind of refractory brick made from high purity or purer raw materials, also corundum mullite block is a high alumina fire brick which made of corundum and mullite main crystalline phase. main material of corundum mullite brick is imported plate corundum, high pure fused corundum, adopt advanced superfine powder adding technology, it is made by the mixing material, drying, molding and burned in high temperature shuttle kiln.

Corundum Mullite Brick Features

  • High quality raw material,
  • High purity corundum,
  • Strong volume stability at high temperatures,
  • Molded with high pressure and high temperature,
  • Good thermal shock resistant,
  • Wear resistance,
  • Chemical attack resistance.

Corundum Mullite Brick Manufacturing Process

Corundum mullite brick is made of synthetic mullite brickand mullite particles to aggregate material are available, and alpha Al2O3 powder for powder, can also be fused or sintered corundum particles to aggregate material, synthetic mullite powder for powder. The aggregate and powder are mixed according to a certain proportion and grain size. The waste liquor of paper pulp with sulfite is used as the binding agent, and the materials are added in a certain order.Fully mixed and even, with friction press or hydraulic press brick molding machine.Adobe after drying, burn into in 1650 ~ 1750 ℃.

Corundum Mullite Brick Price

Generally, cordundum mullite brick is divided into sintering and fused bricks, the price of two kinds of corundum mullite refractory bricks are very different in the market, the price is in the range of thousands to 10,000. We suggest different corundum mullite fire brick should be selected according to different parts of kiln, not only improve the life of furnace, but also reduce the cost.

Use of Corundum Mullite Brick for Furnace

Cordundum mullite brick can direct contact with flame, spalling resistance, high temperature resistant, can be used as heat insulation of high temperature industrial furnace lining. also corundum mullite fire brick can be used as other industrial furnace work layer, mainly used in the petrochemical industry, large and medium-sized ammonia gasifier and magnetic material of gas furnace with material, high temperature industrial kiln facilities material, etc.
