Effect of reactant treatment of rolling slime sewage on slime quality

[摘要] This article considers the way to improve the quality of slime obtained from rolling based on the example of the slimes of the hot rolling mill 2500, Sheet Rolling Shop of the Open Joint-Stock Company "Magnitogorsk Iron and Steel Works" (MMK, OJSC). Hot rolling mill slimes can be used as secondary raw materials for metallurgical (blast-furnace and open- hearth steelmaking) and related manufacturing processes. At elevated slime humidity and high oil concentration its processing becomes rather difficult. Due to the improper slime quality, it is seldom applied for further production and is just accumulated in piles. Such piles pose a serious environmental threat polluting the atmosphere, groundwater, and soil. To resolve this problem, the authors studied the influence of slime sewage reactant treatment on slime quality.
