Corundum not comes stone brick is monovalent

      The unit price of corundum Mo Laishi asks to wait according to technology of raw material, production, client change and change. Mo Laishi brick uses corundum high quality synthesis is Molaishi, high pure corundum is main raw material, add special type additive, classics high pressure shapes, high temperature fire and into.

      Corundum not comes the firebrick that stone brick department points to to high pure or purer raw material is made. Aluminous content of Mo Laishi brick is in common corundum 90% above, among them the existence of impurity of oxide of low melting point, can reduce its high temperature capability. Because this corundum not comes,stone brick unit price should be compared common price of tall aluminous brick is a lot of higher.

      The manage of Mo Laishi brick changes typical corundum function is: Al2O3 ≥ 85% , fe2O3 0.45% , apparent pore is led 19% , intensity of normal temperature compression is more than temperature of 55MPa loading bate to be more than 1700 ℃ , add a hot line to change (1600 ℃ , 3h) ﹣ 0.1% , heatproof shake sex (1100 ℃ water-cooling) be more than 30 times.

      Mo Laishi brick uses corundum normally synthesize Molaishi to make corundum Mo Laishi brick, makings of grain of usable Mo Laishi is aggregate, α - Al2O3 pink expects for pink, frit of usable also report or agglomeration corundum grain expect for aggregate, synthesis Mo Laishi pink is pink to expect. Aggregate and powdery makings deserve to have burden by certain proportion and fraction, it is bond with waste liquid of sulphurous acid pulp, press one methodize feed in raw material. Mix practice adequately even, with attrition the machine that press a brick or hydraulic pressure press bricky machine to shape. After adobe is dry, at 1650 ~1750 ℃ firing.

      Mo Laishi brick can contact corundum directly blaze, fight flake, high temperature resistant, can regard high temperature industry as the adiabatic line of furnace already, also can regard the job of furnace of kiln of other industry high temperature as the layer, basically apply at petrifaction industry, large and medium-sized furnace of synthetic ammonia aerification and stove of magnetic material gas use data, material of establishment of form a complete set of furnace of kiln of high temperature industry.
