Product Description

Big size alumina cylinder crucible for meltiing steel

1, 99.70% corundum 1800 ° C 1650 ° C -1700 ° C corundum in the oxidation and reduction atmosphere, has good high temperature insulation and mechanical strength. The thermal conductivity is large and the thermal expansion rate is small. It does not react with air, water vapor, hydrogen, carbon monoxide or the like above 1700 °C. The short-term maximum operating temperature is 1800 °C.

2, 90.35% corundum 1750 ° C 1600 ° C - 1650 ° C corundum in the oxidation and reducing atmosphere.

3, 85.00% high aluminum 1350 ° C 1290 ° C high aluminum crucible in the oxidation and reducing atmosphere, has good high temperature insulation and mechanical strength. The thermal conductivity is large and the thermal expansion rate is small. Does not react with air, water vapor, hydrogen, carbon monoxide, etc. It can be used for a long time when the temperature of the temperature field does not change much. The short-term maximum operating temperature is 1400 °C.

application

 

1. Corundum is composed of porous fused alumina, which is firm and refractory.

2. Corundum is suitable for melting samples with some weak alkaline substances such as anhydrous Na2CO3 as a flux. It is not suitable for melting samples with strong alkaline substances such as Na2O2 and NaOH and acidic substances (such as K2S2O7, etc.).

3. Characteristics of corundum: high temperature resistance, acid and alkali resistance, rapid cold resistance, and chemical resistance.

4. The shape of corundum: curved, cylindrical.
