我国铸造行业用焦量较大,焦炭主要是作为化铁炉的燃料。铸造化铁对焦炭的要求是:块度大,可燃性、反应性和气孔率小,灰分、硫分低并有一定的强度。现用焦炭有铸造焦、冶金焦、煤气焦和土焦等四种。其中冶金焦和土焦的用量较大。随着我国钢铁工业的发展,冶金焦的供应将日趋紧张。目前由于铸造用焦质
China’s foundry industry with a large amount of coke, coke is mainly used as fuel iron furnace. Forged iron requirements of coke: large block size, flammability, reactivity and porosity, ash, low sulfur and have a certain intensity. Existing coke casting coke, metallurgical coke, gas coke and coke and other four. Metallurgical coke and earth coke in which a larger amount. With the development of China’s steel industry, the supply of metallurgical coke will become increasingly tense. At present, due to casting coke quality
