Aluminium scrap foil melting crucible copper melting

Type: Refractory, refractory crucible Application: Melting Metal Height: Customized Composition: Clay Top Diameter: 50-950mm Bottom Diameter: 40-460mm Name: graphite crucible Material: sic,graphite Working Temperature: above 1850 degree Shape: A-shaped,U-shaped, cylinder-shaped Apparent Porosity: under 24% application: melting non-ferrous metal size: all size 1-graphite crucible 2-choosing graphite and clay material, plastic into U-shaped crucible 3-main melting non-ferrous metal, like copper, aluminum, brass and iron, etc. Silicon carbide graphite crucible Brief Mainly used in the melting of non-ferrous metals, such as copper, aluminum, etc.It has the advantages of fast heat conduction, high temperature resistance, good thermal stability and no reaction with melting. Features Use high thermal conductivity of graphite and other raw materials, shorten the melting time. Heat shock resistance: high heat shock resistance, not easy to crack when cold or hot. High heat resistance: high temperature resistance, can withstand 1200~1650 high temperature.
