Production process of brown corundum

    1. Technical conditions for smelting brown corundum raw materials

     

    For ordinary production of brown corundum, the chemical composition, iron filings and anthracite, the main raw material for the production of brown corundum, have certain quality indicators.

     

    1. The cause of smelting brown corundum raw materials

     

    The bauxite clinker used for smelting brown corundum is different from the bauxite clinker used for producing metal aluminum. brown fused alumina vietnam The bauxite clinker used for smelting brown corundum is bauxite with high AL2O3, TiO2, low SiO2, and CaO, but the relative index of bauxite for producing metal aluminum is not so high.

     

    1. Design of smelting brown corundum process

     

    An important process in the production of brown corundum is smelting. Through smelting, the smelting atmosphere is appropriately controlled to make bauxite, reducing agent and clarifying agent undergo oxidation-reduction reaction at high temperature to remove impurities, so as to obtain corundum that meets quality requirements.

     

    Targeted design of furnace charge, reasonable control of furnace materials. To achieve a good smelting index by optimizing the design of the furnace charge, it is necessary to properly adjust the PH value of the melt in the furnace. According to the capacity of the smelting equipment, design the batch preparation system of the charge. The optimal process design to solve the reasonable charge difference is to divide the smelting charge into the first, middle and later stages, which is very beneficial to the economic effect.www.hslabrasive.com
