Silicon Carbide Refractory Nozzle For Roller Kiln

Product Overviews

Product Overviews of Sic Refractory Nozzle

1. Characteristics of SiC Nozzle

It is a kind of product with high strength, high hardness, high wear resistance,and good oxidation resistance, thermal shock resistance and other properties.

RSIC has more excellent long-term performance ( Compared with RSIC and N-SiC) the bending strength is more than

twice than RSIC,50% high than N-SiC.

2. Applications of Sic Nozzle

The various industrial furnaces, the desulphurization equipment, the large boiers and other machinery , and the ceramics, the machinery ,the metallurgy, the electronics,the chemicals, the petroteum , the iron and steel industry and other fields.

The series of beams are ideal kiln furnitures for sanitary ceramics, household porcelain, building

ceramics, electric porcelain, refractories, etc. They are specially used for load-bearing beams in shuttle kilns, tunnel kilns, roller hearth kilns and other industrial kilns.
