Abstract
The present invention belongs to the field of refractory material and grinding tool. The present invention features that the refractory product may be produced through low-temp sintering at 1,100 deg. c or even without firing, and it can raise the strength of silicon carbide product, prolong its service life and simplify its production process. When the silicon carbide is produced into grinding tool, the present invention can prolong the service life of grinding tool, reduce its firing temperature and production cost, and raise its performance.
Description
The invention belongs to refractory materials and grinding tool field.
The invention has the advantages that and in fire resisting material field, use the intensity that can improve silicon carbide articles that partially carbonized silicon goods can be burnt till, and fire performance is constant, also can make burnt brick in 1100 ℃ of sintering temperatures.Simplified production technique.Be used in the grinding tool field, can make the silicon carbide grinding tool that higher intensity is arranged, reduce firing temperature, simplified production technique greatly.
The objective of the invention is to simplify production technique, reduce the production difficulty, reduce production costs, improve goods work-ing life.
The present invention is achieved in that example 1: the refractory product ratio of components: silicon carbide grain 10～60%
High aluminum shot 0～50%
Lapis amiridis 30～40%
White carbon black 1～2%
Add wedding agent aluminium dihydrogen phosphate 3～5%
At first mix, depressing moulding then,, be finished product after the drying in 100 ℃ of dryings.Can make the refractory brick of required different carborundum contents.The flue dust powder that the also available production ferro-silicon of white carbon black reclaims replaces.Example 2: grinding tool
Adopt the silicon carbide material, adds an amount of white fused alumina fine powder, the flue dust powder that adds 1～2% white carbon black again or produce the ferro-silicon recovery is made grinding tool, burns till to get final product under 1100 ℃ of temperature.
Claims (1)
1, the white carbon black of every utilization (perhaps ferro-silicon production reclaim flue dust) combines with aluminium sesquioxide and the silicon carbide-containing goods made all are this protection domain.
