The main raw material of ferroalloy briquettes is silicon slag, which is pressed into a flat sphere by grinding silicon slag into powder form and adding alloy powders, using professional briquetting equipment. Ferroalloy briquettes are rich in Si elements. Usually, manufacturers will grade ferroalloy briquettes according to their Si element content, and the common grades of ferroalloy briquettes are 45#, 50#, 65# and 70#, etc. According to the different raw materials and processing process, ferroalloy briquettes can be divided into silicon metal briquettes, ferrosilicon briquettes, high carbon silicon briquettes, etc.
Ferroalloy Briquettes Grades | Si | C | P | S |
Ferroalloy Briquette 45# | 45%min | 2.0%max | 0.05%max | 0.05%max |
Ferroalloy Briquette 50# | 50%min | 1.5%max | 0.05%max | 0.05%max |
Ferroalloy Briquette 65# | 65%min | 1.0%max | 0.05%max | 0.05%max |
Ferroalloy Briquette 70# | 70%min | 0.5%max | 0.05%max | 0.05%max |
high carbon silicon briquettes Grades | Si | C | P | S | Sio2 |
high carbon silicon briquette 45/15 | 45%min | 15%max | 0.05%max | 0.05%max | 8%max |
high carbon silicon briquette 50/15 | 50%min | 15%max | 0.05%max | 0.05%max | 5%max |
high carbon silicon briquette 65/15 | 65%min | 15%max | 0.05%max | 0.05%max | 2.5%max |
high carbon silicon briquette 67/18 | 67%min | 18%max | 0.05%max | 0.05%max | 2.5%max |
