    Jan 20, 2017 Guided rollers are used to pull it out and then the steel is cut into the desired lengths. It may be used for beams, billets, slabs or other items, and when the parts are fully cooled they are sent elsewhere for primary forging. Primary Forging. In this step, the rough cast items are formed into shapes through a process called hot rolling

    This is described as semi-finished steel and is the end result of rolling ingots on a rolling mill or by processing them through a continuous casting process. Slabs will have rectangular cross sections and are used as the “starter” metals in the making of flat products such as steel plates or hot rolled coils. Slabs are always flat and rectangular and will typically range from 160mm thicknesses and more

    The molten metal is then allowed to solidify until it becomes a semi-finished slab that is later rolled in the finishing mill. It is used to cast metals of uninterrupted lengths. In this process, the molten metal is continuously supplied to the mold. The mold has an indeterminate length

    Continuous casting of steel produces an endless length of steel which is cut into long slabs or blooms that are ready for shaping in rolling mills. Molten steel is poured into the top of a continuous casting machine and is cooled by passing through a water-cooled mold. Pinch rolls draw the steel downward as it

    steel - Electric-arc steelmaking | Britannica

    Electric-arc steelmaking. About one-quarter of the world’s steel is produced by the electric-arc method, which uses high-current electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. External arc heating permits better thermal control than does the basic oxygen process, in which heating is accomplished by the exothermic oxidation of elements

    Making steel. At Scunthorpe, we use the Basic Oxygen Steelmaking (BOS) process – our modern convertors (or vessels) take a combined charge of scrap and liquid iron of up to 330 tonnes and convert this into steel in just 25 minutes. When the liquid iron arrives at the BOS Plant, it’s poured from the torpedoes into refractory-lined charging
