· Example: A mill in closed circuit with a classifier receives 300 dry tons of crude ore per day, and the percentages of solid are respectively 25, 50, and 84% in the classifier overflow, feed to classifier, and sand, equivalent to L: S ratios of,, and
Most steel mills use a blend of different grades of ore, and a mix of sinter, lumps and fines, but the quality requirements depend on the circumstances and availability. For example, ore used in the directreduction process to make directreduced iron (DRI) or hotbriquetted iron (HBI) destined for melting in an electricarc furnace (EAF) needs to be of much higher grade than that fed into a ...
Blooming mills can be classified as either twohigh or threehigh, depending on the number of rolls used. The two rolls of the twohigh mill can be reversed so that the ingot is flattened and lengthened as it passes back and forth between the rolls. The top and bottom rolls of the threehigh mill turn in one direction while the middle roll turns in the opposite direction. The ingot is ...
Mill scale, a form of iron oxide (Fe 3 O 4), is used to reduce carbon content. Aluminum ferrosilicon is added if the steel is to be "killed." A killed steel is one that has been deoxidized to prevent gas evolution in the ingot mold, making a more uniform steel. "Rimmed" steel is steel that has not been deoxidized and gas pockets and holes from ...
