The quartz ceramic roller can be divided into two kinds of hollow roll and solid roller, also known as the bottom roller. More than 120mm in diameter is hollow roller, and more than 120mm is solid roller. High purity fused silica was used as raw material, near net size and fine cold processing after high temperature sintering.
The hollow roller is mainly used in the production line of non oriented silicon steel, the bottom roller of supporting and transporting silicon steel plate in the annealing furnace of galvanizing line, the transition roller table, the annealing furnace roller in the float glass production line, the roller table of other kinds of heat treatment furnace, sintering furnace and precipitating furnace.
The solid roller is mostly used in the high grade glass annealing furnace, such as glass horizontal steel furnace, electronic glass and other kinds of heat treatment furnace, sintering furnace and precipitation furnace.
●The material has good thermal stability, high temperature and no deformation, and the maximum use temperature can reach 1100.
●It can be replaced in a hot state.
●The machining precision is high, and it can ensure the precise installation of the ceramic roller in the equipment to ensure the stable operation of the equipment.
●The chemical properties are very stable, and the surface of the roller is hardly attached to the oxide.
●Compared with other materials, it has the advantages of good wear resistance, long service life and high quality of the product.
The company can produce various specifications of quartz ceramic hollow rolls and solid rolls below 400 x 5000mm according to customer's requirements.
We produce high-grade specific form and low expansion ceramicgoods. Size: tile(max 3500*1000*5mm) , pipe(max Φ500×5000mm, min Φ1×50mm), kettle(max Φ1000×1000mm). The ceramic products can be used in nonferrous metallurgy and precious metals smelting casting, can be used as lining and pad (retainer plate), and transmission components. Also can be used as heat insulation porcelain in power industry and heat-resistant and corrosion-resistant components in chemical industry.
According to customers` requirements, in view of the actual working environment, we make material design. Using high quality imported purity raw materials, and applying sophisticated molding process according to the product performance, we fire the products in high temperature furnace. According to our experience, we do cold-work on ceramic products to meet customers` requirements.
Our company has the research and production experience on quartz ceramic, alumina ceramic products and zirconium oxide products. Company has strong technical foundation, powerful capacity for independent innovation and achievements transformation of engineering ability.
Use
Ideal substitute for graphite rolls and ceramic coating rolls, prevent oxidation and dross build-up, prolong service life with improved quality of metal belt.
