corundum mullite cruicible

Introduction & Application

Corundum/alumina mullite crucible choose high purity corundum , mullite and other refractory materials as the main substrate. We use casting mold and sintering furnace to achieve production in quantity.The product not only has the high temperature performance of corundum material, but also combines the thermal shock stability of mullite (temperature toughness). It has good resistance to high temperature creep and high mechanical strength at high temperature

Strict inspection and unique technology make our quality as good as imported products.It is widely applied to black, gray casting, casting all kinds of alloys and gold and silver jewelry, metal jewelry casting industry.

high-temperature crucible; high temperature resistant materials.refractory ceramics;
custom-made item:can be made according to customer’s requiring sizes.
applied range: metal melting, such as gold, silver, copper, steel, iron etc.

Production Process

High-purity corundum and mullite sand → high-purity graphite mold → vacuum charge molding → vacuum arc melting → natural cooling stripping → quartz crucible preliminary testing → cold processing sandblasting, cutting, chamfering → secondary detection → ultra-clean cleaning, ultrasonic , High-pressure spray, automatic drying. Heating baking, spraying → three times → packaging → finished product and storage

Application

It is widely used in high temperature furnace , like magnetic material and electronic ceramic and so on.
