Multiobjective optimization of the production process for ...
· The production process of ground granulated blast furnace slag (GGBS) aims to produce products of the best grade and the highest yields. However, grade and yields are two competing objectives which can not be optimized at the same time by one single solution. Meanwhile, the production process is a multivariable strong coupling complied nonlinear system. It is hard to establish the .

Slag
Slag is drawn off the furnace just before the molten steel is poured into ladles for ingotting. Ferrous and nonferrous smelting processes produce different slags. The smelting of copper, lead and bauxite in nonferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as ironsiliebased slags.

Coal Bottom Ash/Boiler Slag
· Wetbottom boiler slag is a term that describes the molten condition of the ash as it is drawn from the bottom of the slagtap or cyclone furnaces. At intervals, highpressure water jets wash the boiler slag from the hopper pit into a sluiceway which is then conveys it to a collection basin for dewatering, possible crushing or screening, and either disposal or reuse.
