Process Of Production:
High Alumina Raw Materials
OAL is India’s largest manufacturer of Calcined and Fused Alumina products. We manufacture a wide range of Aluminous raw materials including Brown Fused Alumina, White Fused Alumina, Pink Fused Alumina, White Fused Mullite, Fused Zirconia Mullite (ZIRMUL), Fused Alumina-Magnesia Spinnel, Calcined Bauxite and High Alumina Refractory Cement. All these products cater to the needs of grinding wheel and refractory manufacturers. Fused Alumina is also used for shot blasting and cleaning purposes. This range of products is being manufactured at the Company’s facility in Porbandar (Gujarat).
The key raw materials for these products are Bauxite and Calcined Alumina. Bauxite is sourced primarily from the Company’s own mines located in the Jamnagar and Bhuj districts of Gujarat. Calcined Alumina is sourced from aluminium manufacturing companies.
Application:
Lightweight insulating castable is made by light weight refractory aggregate powder,binder and admixture
1. Binder- high purity calcium aluminate cement or aluminium dihydrogen phosphate
2. Refractory aggregate and power
3. fire clay (chamotte) based
4. high alumina based
5. mullite corundum based
6. silica based etc
Feature
1. Low bulk density and low thermal conductivity.
2. High mechanical strength.
