Metallurgical crucible
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.
