Product Description

`

 

During the production and processing of black silicon carbide, a large amount of silicon carbide with a content of less than 90% is formed and produced, commonly known as low silicon. The main uses of low-content black silicon carbide are deoxidizers, gun mud, castables, and trench materials in the refractory industry and steel making industry.
Our company supplies silicon carbide in various specifications. The product content distribution is: 98%, 95%, 90%, 88%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50% ,45%,40%. The particle size can be customized according to customer needs, usually 0-1mm, 0-50mm, 1-10mm, 100- 400 mesh, etc.

Product performance
1. High chemical stability, low thermal expansion coefficient, high thermal conductivity, and resistance temperature characteristics are opposite to those of metals;
2. High hardness, with Mohs hardness reaching 9.5, it is the first wear-resistant additive for materials;
3. Wear-resistant, high temperature resistant, corrosion resistant, acid and alkali solvent resistant, widely used in coatings and paints to increase wear resistance;
4. It has good toughness, excellent grinding performance, and excellent electrical dissipation and thermal conductivity.

In the process of smelting cast iron with intermediate frequency furnace, the accompanying problems such as poor nodularization, less graphite balls, large use of nodularizing agent, more supercooled graphite in gray iron castings, A-type graphite can not meet customer requirements, and processing difficulties follow. This product can effectively improve the metallurgical quality of molten iron, thereby reducing the above problems.
Features:
1. Increase the graphite nucleation core and enhance the graphite nucleation ability. Reduce the subcooling degree of molten iron and reduce the tendency of castings to white.
2. Good deoxidation effect, purify molten iron.
3. Extend the service life of the furnace lining.
4. Reduce the supercooled graphite in gray cast iron and promote the generation of A-type graphite.
5. Adding to ductile iron production can increase the number of graphite balls, improve the nodularization rate, make the graphite balls more round and small, and reduce the amount of nodularizing agent.
