A | B | C | D | E | F | I | G | L | P | R | S | T Alloy Steel steel with one or more specific elements added to create special properties Annealing the controlled heating and cooling to soften steel Bar steel shapes up to 75mm in diameter produced in straight lengths, such as rounds, squares, hexagons, angles, channels, flats, T-bar or reinforcing bar Billet a 12 metre long semi-finished steel shape, produced from a caster or rolled from a bloom Blast Furnace a huge oven or furnace (up to 100 metres tall) which operates continuously to produce iron. It is socalled because of the air blasts which are part of the iron making process. Bloom a steel shape, the product of continuous casting, varying in dimension. Usually about 630mm by 400mm and 5-6m in length. BOS Vessel a furnace where blasts of oxygen are used to transform iron into steel Carbon Steel iron with less than 1% carbon content making the metal hard but not brittle. Casting the process of pouring molten metal into a mould, so that the cooled solid metal retains the shape of the mould Charging feeding the furnace with raw materials Coke Ovens a series of tall, gas fired, air-fight brick ovens (called a battery) in which coal is baked, leaving metallurgical coke Continuous Casting continuous forming of semi-finished steel into sections, e.g. slabs, blooms and billets, direct from molten steel Drawing pulling steel shapes through tapered dies to produce wire Dummy Bar a metal bar used to close the bottom of the mould in the casting machine Electric Arc Furnace a furnace that uses electric power to melt scrap steel to produce new steel Flux limestone or other materials used to collect impurities in the iron and steelmaking processes Integrated Steelworks works including all major production phases from raw materials (iron ore and coke) to rolled steel Galvanise the coating of iron or steel with zinc to protect it from corrosion Ladle a 'bucket' lined with refractory (heat resistant) bricks used to transport molten steel from process to process in a steel plant. Lance a long metallic tube through which oxygen is blown into the BOS vessel under high pressure Pellets fine particles of iron ore n-dxed with bonding clay and roasted into hard round balls for blast furnace feed Pickling use of hot acid solution to remove oxides and scale from steel to ensure good surface quality in cold rolling Plate flat rolled steel product more than 3mm thick Refractories heat resistant materials, often bricks which coat linings of furnaces and ladles Rod round steel bar, ranging from 5.5mm to 12.7mm diameter, produced in coils. Used as feed for wire mills Roll Forming rolling coated steel into different profiles for roofing, fences and garage doors Scrap Steel good quality steel such as cropped ends of semi-finished steel products, steel damaged in production, and old steel goods such as cars, refrigerators, etc. Slab a semi-finished steel shape measuring around 1m by 230mm by 12m long produced in a continuous caster Slag a by-product of iron and steelmaking largely composed of limestone. It is solidified and used in soil mix, road surfaces and cement Sheet and Strip flat rolled steel product less than 3mm thick Sinter fine particles of iron ore, coke and limestone, fused into lumps for use as blast furnace feed Stainless Steel an alloy steel containing chromium, nickel and molybdenum, It is corrosion resistant, so is used in kitchens and laundries Stand an arrangement of rolls through which steel is passed to alter its shape. A mill may consist of one or more stands Tapping running off molten steel from the taphole in a furnace or vessel Terne Steel sheet steel coated in a lead/tin alloy coating Torpedo Ladles huge torpedo shaped vessels which transport molten iron to the steelmaking area Tinplate sheet steel coated with a thin layer of tin, used for food cans, paint tins, etc. Tuyeres nozzles arranged in a ring around the base of the blast furnace, through which air blasts are injected
