C-shaped Damper Brick

    In addition to the intrinsic quality of the C-shaped damper brick, the impact of the appearance of crack defects on the service life can not be ignored. V-method of casting, the melt by the role of negative pressure, the temperature gradient above and below the brick and around the brick material is very uniform, the thermal stress of the brick material becomes smaller, reducing the thermal cracking of the brick material products. Negative pressure molding brick casting after holding pressure process to be unpressurized sand collapse, almost no obstruction to the formation of brick cooling contraction, which is also negative pressure molding products crack tendency to reduce one of the reasons.
