Overview

      Haite company 's metallurgical grade silicon carbide materials are mainly used in the foundry industry. Because of its chemical inertness at any temperature, thermal shock resistance, abrasion resistance, and sinterability. Its characteristics combine the high-purity material characteristics of silicon and carbon. Metallurgical grade silicon carbide is not only an additive for special alloys, it is also used as an inoculant for iron-based alloys.

Functions

The main functions of metallurgical silicon carbide in cast iron are:

(1) Silicon carbide can prevent the precipitation of carbides. And it can increase the amount of ferrite and reduce white cast.

(2) Silicon carbide significantly improves impact resistance performance, and improves tensile strength and yield strength performance.

(3) Silicon carbide increases fluidity. It stabilizes the composition of molten iron and prevents segregation.

(4) Silicon carbide reduces wall thickness sensitivity. It can make the organization dense and the cutting surface smooth.

(5) Silicon carbide enhances the graphite nucleation ability and increases the graphite core.

(6) For ductile iron, silicon carbide is a powerful deoxidizer. It can reduce the amount of spheroidizing agent added and increase the spheroidizing rate.

(7) Silicon carbide can reduce rusty waste and alloys, which will reduce the cost of molten iron.

(8) Silicon carbide can eliminate the oxidation factor of molten iron and reduce the oxidation of the furnace wall, which can extend the lifetime of the furnace wall by 30%.

(9) Silicon carbide has a strong deoxidation effect, which can purify molten iron.
