The hot rolling process the primary function of the hot strip mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
In the second step reaction tank 3, lime is typically used for the precipitation reaction.In this flow diagram, a process known as high density sludge hds is employed to help promote precipitation.The heart of the hds process is the ph in the hds or densification tank which needs to be at a ph of 11.5 or higher.

MoreThe iron, at around 1480c, is transferred to the vanadium recovery unit vru, where vanadium-rich slag is recovered for export and further processing into a steel strengthening additive.The ironmaking plant at glenbrook has the capacity to produce 650,000 tonnes of molten iron.
MoreOre is stockpiled 1 at the processing plant, and the process begins by feeding the ore into a hopper with a loader.The ore is conveyed, and lime is added 2 to raise the ph of the ore.Following crushing through a jaw crusher 3, the ore is fed into the semi autogenous grinding sag mill 4 along with water and steel.
MoreBeneficiation of iron ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation.All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500.
MoreThe process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron.The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel.The electric arc furnace melts recycled steel.
