Audited Supplier Introduction:
Calcined bauxite is produced by sintering/calcining with natural bauxite ore of low iron, low alkali at temperatures of 1600-1800ºC in the rotary kiln or round kiln through pre-heationg, calcination, cooling and other processes. During Calcining, it can be removed impurities and improving the content of alumina. Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Therefore calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants.
Application:
1.Aluminum industry.
2.Precision casting.
3.Refractory industry.
4.Silicic acid aluminum fire fiber.
5.Mixed with magnesium oxide,it can be an nice bonding agent,especially for pouring entire steel teeming ladle lining.
6.Manufacture bauxite cement,grinding abrasives,ceramic industry,and chemical industry for making aluminum
