8.2 Metallurgical Coke. Metallurgical coke is used in blast furnaces. Its role there is threefold: to support the iron ore burden (high strength); to act as the carbon source for the reduction of iron oxide ores (suitably low reactivity); and to provide thermal energy. Metallurgical coke must have an optical texture of fine-grained mosaics (1.5 ...
WhatsApp: +86 18221755073It is believed that a good quality metallurgical coke should have low CRI and high CSR. If the CRI is too high, the starting temperature of the reaction between the coke and CO 2 will decrease.
