Description

The Description of Pyrophyllite Brick:

Pyrophyllite brick is a refractory product made of natural pyrophyllite as raw material, through rationalized batching, mixing, high pressure pressing and high temperature sintering. The pyrophyllite brick produced by Rongsheng Refractory not only has the characteristics of low thermal conductivity, but also has good thermal shock stability performance, and also has certain thermal expansion performance under high temperature conditions, which can seal the brick joints and ensure the safe operation of high temperature equipment.


Application:

The thermal expansion performance and excellent thermal shock stability of the pyrophyllite brick produced by Rongsheng Refractory determine that the permanent layer built by this product has good integrity, is not easy to peel off, and has a long service life. And because the thermal conductivity of the wax stone brick is relatively low, it can be used in the permanent layer of high-temperature equipment such as ladle, iron ladle, tundish, torpedo car, etc., to play a good role in thermal insulation. Among them, pyrophyllite brick (RS-PY83) is a fired brick made of selected high-silica pyrophyllite as raw material. In addition to the advantages of ordinary pyrophyllite brick, it also has good slag corrosion resistance, no pollution to molten steel and non-stick properties. Slag and other characteristics, it is an ideal material for masonry ladle and unrefined ladle working layer.
