99% Al2O3 0.5-1mm refractory abrasive tabular alumina
Description:
Tabular alumina is made of Al2O3, after ingredients, grinding and forming, smelting in high temperature furnace turned to α- Al2O3.
Production feature:
Tabular alumina has good heat resistance and good bulk temperature thermal shock capabilities. The crystal staggered plate shape, to increasing the mechanical strength of the particles; interior structure full of closed pores, high bulk density, low apparent porosity and water absorption, to reducing the amount of fluid re-use productions; With good physical properties like: high refractoriness, excellent thermal shock resistance, low shrinkage and good thermal load strength etc. Meanwhile, high-purity avoiding damage to machines.
Production process
1.imported Australian alumina powder 2. Fine grinding
3. Ball forming machine 4. Testing of raw balls
5.High temperature calcine 6. Extreme cooling
7.Cooked ball detection 8. Granulator
9.Sub-assembly Line 10. Determination of chemical constituents
11.physical property testing 12. Storage of qualified products
Application:
Tabular alumina is an ideal refractory material, either can be used in various refractory alumina, or can be add in other unshaped refractories
