Description of Crucible:
Crucibles mainly include silicon carbide crucible and graphite
crucible, which are mainly made of flake graphite and silicon
carbide. They have the characteristics of good thermal
conductivity, high density, corrosion resistance, less slag
adhesion, high mechanical strength, oxidation resistance, thermal
shock resistance, etc. They do not react with molten metals in the
smelting process, and are not easy to leak and adhere.
The high temperature smelting silicon carbide graphite grucible
produced by Rongsheng Group have the characteristics of good
flexibility, not easy to crack, and long service life, and also the
large capacity of the crucible increases the output, guarantees the
quality, saves labor and lots of costs. The company has
successively supplied customers in more than 60 countries. Through
our company’s continuous improvement of products and strict control
of the production process, the stability of product quality has
been improved, so that customers can get real benefits and have won
unanimous praise from users.
Our Service and Advantage
1.Professional manufacturer and supplier in China.
2.Offer quality products with good price.
3.Can do customized design.
4.Samples test and customized service available.
Applications of Silicon Carbide Graphite Crucibles:
The series of crucibles have been widely used in the smelting of
alloy tool steel and the smelting of non-ferrous metals such as
copper, aluminum and their alloys.
