STEEL ROLLING MILLS . INTRODUCTION . Molten steel is either poured into large ingots or continuously cast to produce slabs, billets or blooms. Rolling mills reduce the ingots or other cast material in size, and shape them into usable products. The rolling process requires considerable amounts of energy. High horsepower motors turn the rolls,

As steel is not ductile at room temperature, heavier reductions require it to be heated to temperatures of 150012 00 . 0. C to make it ductile by converting its crystal structure from BCC to FCC.

As minimills expand their product abilities to sheet steel, they require much higher grades of scrap to approach integrated mill quality. Enabling the minimills to use iron ore without the blast furnace, DRI can serve as a low residual raw material and alleviate the minimills' dependence on cleaner, higher priced scrap.

Fortunately, only 70% of steel is made with coal today. The other 30% of the world's steel production uses electric arc furnaces, fed with recycled steel or iron smelted with natural gas and hydrogen. Recycling is obviously a priority to reduce demand for new steel, but steel is already mostly recycled, so we'll still need some new steel.
