Product Description

Years the company has committed to a variety of industrial ceramics production use, especially for R & D and production of fused silica ceramics forefront of the industry. We produce glass tempering furnace with a quartz ceramic rollers, metal with the heat treatment of quartz ceramic tube, high alumina corundum ceramic tube for glass furnace quartz ceiling brick gate tiles and fine quartz ceramic refractory, quality and performance of a number of indicators have reached international advanced level, the majority of users praise and recognition.
Fused silica ceramic rollers
● net size proprietary molding process to prevent over-burning, has a higher strength and stiffness, high hardness and good wear resistance, to ensure good machining accuracy
● very low coefficient of thermal expansion, a strong thermal shock resistance, temperature range, no bending deformation, long life
● perfect and reliable shaft-head connection technology, easy to use, reliable, precise and stable transmission
Fine cold working process, the surface smooth and delicate, to avoid scratches on products
