1.Cold rolling
Passing a sheet or strip that has previously been hot rolled and picked through cold rolls (below the softening temperature of the metal). Cold rolling makes a product that is thinner, smoother and stronger than can be made by hot rolling alone.
2.Continuous casting
A process for solidifying steel in the form of a continuous strand rather than individual ingots. Molten steel is poured into open-bottomed, water-cooled moulds. As the molten steel passes through the mould, the outer shell solidifies.
3.CRC
Cold rolled coil (see cold rolling)
4.Crude steel
Steel in the first solid state after melting, suitable for further processing or for sale. Synonymous with raw steel.
5.Direct reduction
A group of processes for making iron from ore without exceeding the melting temperature. No blast furnace is needed.
6.Electric arc furnace
A furnace that melts steel scrap using the heat generated by a high power electric arc. During the melting process, elements are added to achieve the correct chemistry and oxygen is blown into the furnace to purify the steel.
7.Electrical steels
Specially manufactured cold-rolled sheet and strip containing silicon, processed to develop definite magnetic characteristics for use by the electrical industry.
8.Green steel
Green steel is being used and interpreted by many different parties to mean different things, often in the context of marketing new more environmentally conscious products. It has been used to refer to steel manufactured using breakthrough technology, steel produced from scrap, reused and remanufactured steel, and conventional steel with emissions offset through the retirement of carbon units or allowances.
9.Fossil-free steel
Fossil-free steel is steel manufactured without using any fossil fuels such as coal or natural gas, nor any fossil fuel-derived energy.
10.Flat products
A type of finished rolled steel product like steel strip and plate.
