Quartz ceramic guide tube and rollers
Main characteristics
►Low thermal conductivity
It can reduce the supercooling of the edge and bottom surface of the glass ribbon and eliminate stress cracks.
►High surface finish
Fused silica ceramic roller has high surface finish which does not adhere to tin ash. It effectively reduces defects, such as nodulation on the glass surface and so on.
►No deformation at high temperature
Fused silica ceramic roller does not deform at high temperature, which greatly improves the glass products’ quality.
►Excellent wear resistance and limited defects
Fused silica ceramic roller has excellent wear resistance and limited defects, which reduces the change times of rollers and cost and improves the production efficiency.
►Special connection structure between steel head and roller body
Fused silica ceramic roller has special connection structure between steel head and roller body, which will never loosen.
Fused silica ceramic crucibles
Fused silica ceramic crucibles can be used for melting special glass, non-ferrous metallurgy and calcination of rare earth, high-purity alumina (gem grade), battery materials, etc.
Fused silica ceramic crucibles play the key role in polysilicon ingot furnace for solar cells. They can be used as the containers for polysilicon raw materials. Such kind of crucibles work continuously at a high temperature of 1550 ℃ to melt it. Its use conditions are extremely harsh, which leads extremely strict requirements on the purity, strength, microstructure, high-temperature performance, thermal shock stability and dimensional accuracy of the crucible. KSINO adopts the gelation technique to ensure high product yield rate and stable product quality.
Advantage:
►Limited appearance defects
►Excellent high temperature performance and thermal shock stability
►Advanced production technique
Float glass production
Quartz ceramic cover brick
Depending on mature technique, KSINO can produce a whole cover plate with a length of 3000mm and a width of 600mm. It will also decrease the joints and improve the sealing performance.
Advantages:
The product has excellent thermal shock stability. Under the normal working temperature of the flow channel, this product can enable the staff to replace the cover plate in the least time, which is conducive to reducing the downtime and improving the production efficiency.
Quartz ceramic shutter
Advantages:
By changing the flow rate of glass in the center of flow channel, the inclusions and defects are pushed to both sides of the glass plate. Based on corrosion of refractory materials in the flow channel, KSINO can design a shutter to change the flow of liquid glass and the atmosphere of the flow channel. KSINO can customize shutters with special shapes and sizes according to our techniques.
Electric silicon steel industry
Quartz ceramic roller is used in glass horizontal tempering furnace and metallurgical strip heat treatment furnace, which can be used to support and transport glass or metal strips.
Quartz ceramic rollers have high strength, excellent thermal shock stability and high technique accuracy. They will not deformed at high temperature. Especially, the products have long service life.
Quartz ceramic rollers have stable and reliable product quality, which can replace imported products.
KSINO can produce Quartz ceramic rollers with size of 300*3800mm based on customer drawings.
