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.
