Product Description

Product Description

 

 

Product Introduction

Production granularity:8#-600#.
there are two series of F series and P series.

Production process:First of all high-quality brown fused alumina must be selected.After strict inspection,they are put into saggars and entered into the tunnel kin for high-temperature calcination,heat preservation and cooling processes to ensure the toughness and appearance of the calcined abrasives.

Product features:Smallexpansion coefficient,
cleanliness increased by more than 50%thanbefore calcination,toughness increased by more than 15%than before calcination,thus improving the grinding efficiency of abrasive tools.

Product use:Mainly used for high-grade resin abrasives and coated abrasives.

High temperature calcination Brown Corundum Besides being used in refractory materials, grinding wheel and grinding tool manufacturing, precision casting and other fields, it is also widely used in the following fields:

1. Sandblasting
2. Free grinding
3. Resin abrasives
4. Coated abrasives
5. Functional filler
6. Filter media
7. Hydraulic cutting
