Реферат | Iron and steel industry production is accompanied by generation of large amount of solid industrial residuals. Thus, annual reproduction of solid industrial residuals at the iron and steel enterprises of the Ural region comprises over 120 million tons. The basic processes for industrial residuals disposal and recycling have been considered and the simplest and most promising process, such as briquetting, has been emphasized. Recycling of iron and zinc containing dust and sludge from EAF gas cleaning systems into steelmaking processes is the most perspective solution to the problem of their disposal up to date; furthermore, it does not require a high capital expenditure and processing costs. Preference should be given to a common and reliable option for recycling of iron and zinc containing dust and sludge into the steelmaking processes in the form of slag-forming and metal charge (oxide and carbon) briquettes. |
