The 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 ...

The process always starts with hot rolling. Hot rolling refers to the process of rolling steel at a temperature typically above 900 °C, greater than its recrystallisation temperature. This allows steel sheets to be made in larger, thicker sizes, ideal for the manufacture of railway rails, large beams, or girders. Hot rolling vs. cold rolling

Grinding. This is the second size reduction process in a pellet plant. In order to improve the wood pellet quality and output and lower the energy consumption of the pellet mill, we use a hammer mill to grind the raw materials into small particles with a diameter less than 5mm. The smaller the raw materials are, the better wood pellet we make.

Steel mills ' primary feature is rolling steel, a procedure that reduces the cross section of the metal while increasing its length proportionately. Generally, rolling mills are graded according to the content they produce. Direct drive is chosen if the mill's speed allows. In general, direct drive (directconnected motor) is not desirable for speeds less than 150 rpm and outputs less than 750 kW.
