• Product name: Tap hole clay



    Due to good ductility and adhesion of tap hole clay, The tap hole is compacted and easy to form clay pack. The stable length of tap hole is beneficial to the maintenance of furnace wall in tap hole area,

    After the clay into the tap hole, it can be quickly sintering and obtain the strength, so the erosion resistance and corrosion resistance of the tap hole are good. Flow rate of hot metal and slag is stable in the process of tapping, which can ensure the furnace tapping all the hot metal and slag, so the furnace space is large, active and the furnace condition is improved, which is beneficial to strengthening smelting to improve the pig iron production.

    it has the appropriate strength under each temperature gradient , the tap hole is easy to open, the open rate of drilling is high, and the labor intensity is low.

    Due to the use of environmental protection binder, less black smoke, more environmental protection.
