High quality fused magnesia and high purity Magnesite refractory bricks for RH furnace lining
RH furnace refractory configuration - Middle and upper troughs
The middle and upper troughs are mainly located in the impact position of the top lance for oxygen blowing and the alloy chute feeding, and the splash of molten steel and slag on the working lining is serious. The temperature fluctuates greatly, and the oxidation of iron, silicon, manganese, aluminum and other elements in the alloy and molten steel together with the slag in the molten steel causes the erosion of the working lining of the refactory material. The damage is more serious.
Semi-rebonded magnesia-chrome brick XBMGe-20 for working lining, high-alumina brick XLZ-55 or direct-bonding magnesia-chrome brick XZMGe-12 for secondary working lining, lightweight high-alumina brick XLG-1.0 for thermal insulation lining, thermal insulation lining Use calcium silicate board.
An expansion joint is left at the contact part of the upper groove and the hot bending pipe, which is filled with aluminum silicate fiber cotton.
