Product Description

$m density heat insulation refractory plate vermiculite board used for metal steel ladle-1$

the Millegap vermiculite boards are made of inorganic mineral expanded vermiculite, combined with inorganic binder and pressed by special technology. It is characterized by high temperature resistance of 1,200℃, thermal conductivity lower than 0.28W/m.K, non-combustibility, non-pollution, and no emission of harmful substances. Widely used in heat treatment equipment refractory heat insulation applications. According to the user needs according to the sample or drawing mold production. Thickness 8-80mm.

Compared with the traditional insulation layer, the heat preservation effect is good, can make the thickness of the insulation layer reduced to 10~18mm, at the same time can be refractory temperature up to 1200℃. The wall temperature of the middle ladle and the temperature drop of molten steel drop significantly, which can make the temperature drop of the ladle less than 50℃, which is conducive to the stable control of molten steel temperature and can effectively achieve the purpose of energy saving.
