Fireclay blocks for bottom of glass tank furnace

    The fireclay blocks are made by using vibration-casting technology and sintered at high temperature,so,

the blocks are with uniform inner structure.

            Molke Bricks for Tin-bath and Low porosity fireclay bricks

                                                             Molke Sn trough bricks

Molke bricks for Sn trough are made from high temperature synthesized materials. They are mainly used as tin-bath bottom bricks of float glass furnace due to their good thermal shock resistance and good corrosion resistance to alkali and Sn. According to application at high, middle, low temperature of the tin-bath of float glass furnace, we developed three series of Molke bricks i.e. A, B, C, for the application at different temperature areas so that zone lining can be realized.
