The product characteristic does not burn
the magnesium chromium brick to use the high quality magnetite and the chrome
ore is a raw material, Take gathers the phosphate as the cement, Takes shape,
the low temperature heat treatment after the high pressure makes. The product
with fires the product to compare, The manufacture working procedure
simplifies, the cost is low, Moreover the normal temperature pressure
resistance intensity high, the porosity low, the heat shock stability is good.
But will gather the phosphate
chemistry cement about 100 completely to decompose,Does not burn the magnesium chromium brick under this
temperature the center high temperature structural strength to be low. Is
stopping the kiln frequently, the revolution rate low aqueous method rotary
kiln fires the belt use effect to be good.
