Nitrided Ferro Chrome
The sulfur in high-carbon ferrochrome comes from raw materials, of which coke and chromium ore bring in the majority of the sulfur. The sulfur in coke exists in the form of sulfide (FeS, CaS) or organic sulfur. In the actual production process, the raw materials 8%~15% of the sulfur in the alloy enters the alloy, 20%~30% volatilizes, and 60%~70% enters the slag. The sulfur entering the alloy will form a series of sulfides with chromium, such as: CrS, Cr2S3, etc. CrS melts without decomposing at 1565C, and decomposes to form Cr15S6 below 800C. Since the melting point of sulfides is lower than that of ferrochrome, these sulfides are distributed on the surface of high carbon ferrochrome.
