As a product with a large procurement volume, it is very important to distinguish the quality of high carbon ferrochromium. So how to evaluate the quality of high carbon ferrochromium? The production of high carbon ferrochrome requires iron alloy raw materials such as chrome ore, coke, and silica. Sometimes, in order to adjust the slag type, a certain amount of white ash or dolomite needs to be added. High carbon ferrochrome manufacturers have high requirements for raw materials, such as high content of useful elements, good performance, good particle size, and significant energy conservation and consumption reduction. To evaluate the quality of high carbon ferrochrome, we can start with raw materials.

The requirements for good high carbon ferrochromium ore include chemical composition, Cr2O3 ≥ 38, Cr/Fe>2.2, P<0.8, C content not exceeding 0.2, and moisture content not exceeding 18-22%; The physical state requires that the ore should not be mixed with miscellaneous stones, soil, and other impurities. The particle size of a piece of chromium ore entering the furnace is 5-60mm, and the amount below 5mm should not exceed 20% of the total amount.

Good high carbon ferrochrome requires coke with chemical composition requirements: fixed carbon>83%, ash<16%, volatile content between 1.5 and 2.5%, total sulfur not more than 0.6%, moisture not more than 10%, and P2O6 content not more than 0.04%; The physical state requires the addition of coke with a particle size of 20-40mm. Metallurgical materials should not be too large or too crushed, and should not be mixed with soil, impurities, or powder.
