| Magnesium Ferrosilican | a ferroalloy used in the production of ductile iron which acts as a nodulariser, changing the metallurgical structure to encourage the required mechanical properties |
| | |
| Metallurgical Chemicals | any of a wide group of chemicals which can be used in any of the metallurgical processes i.e. alloying elements, resin binders, fluxes etc |
| | |
| Microsilica | a fine-structured form of a non-metallic naturally occurring material (oxide of the element silicon), used in combination with other materials in glass, concrete, brick and refractories |
| | |
| Mould Flux | synthetic granular or powder product used to cover the liquid steel surface in the continuous casting mould for the purposes of lubrication, insulation and inclusion (impurity) removal |
| | |
| Nodulariser | an element (often magnesium based) which is introduced into iron to alter its metallurgical properties, promoting discrete nodules to improve the ductility of the metal |
| | |
| Non-Ferrous | Of, or relating to metals other than iron e.g. aluminium, copper, bronze etc. |
| | |
| Organic Resins | chemical binder materials used in the foundry process, which are formed from elements and compounds that contain carbon and hydrogen |
| | |
| Parting Agents | barrier materials, often used during the forming of sand moulds and cores, to allow the pattern to be removed without sticking to the sand |
| | |
| Powder and Granulated Fluxes | a chemical in powder or granule form which is added to liquid metal in a furnace or ladle to promote fusing, cleaning or to prevent the formation of oxides |
| | |
| Refactories | a material for use in the construction of vessels or products, able to maintain its strength and integrity in the presence of high temperatures, mechanical and chemical erosion e.g. in contact with molten iron or steel |
| | |
| Refactory Paints | a refractory coating, often applied to sand moulds and cores, which is capable of withstanding the high temperatures of molten metal e.g. used to improve surface finish of castings |
| | |
| Resin Binders | chemical materials (most often liquid) which are mixed with sands to allow moulds and cores to be formed, into or around which molten metal can be poured |
| | |
| Rolling and Finishing Processes | (in a steelmill): processes for the conversion of semi-finished shapes, such as slabs, blooms and billets, to products, such as steel strip, plates, tubes and reinforcing bars, which are used in customers' industrial processes e.g. for production of automobiles, white goods, etc., and in construction projects |
| | |
| Sand Additives | chemicals which are added to mould and core sand to overcome impurities and differences in physical properties, e.g. to minimise problems where molten metal penetrates between round sand grams |
| | |
| Sand Cores and Moulds | preformed sand shapes which represent the inner and outer dimensions of a casting; when combined, they form a cavity into which molten metal is poured and the casting shape is described |
| | |
| Secondary Steel Making | the refining (adjustment of chemical composition) which is carried out to the steel in the ladle after it leaves the melting furnace and before it is transferred to the tundish |
| | |
| Slab | continuously cast semi-finished steel product, rectangular in section and subsequently rolled into steel strips or other flat product. Though there are no precise dimensions, a slab usually has a section size ranging from 70-300mm thick and 1,000¬-3,000mm wide |
| | |
| Slag Retention Products | products to hold back the 'slag' or impurities on the surface of the |
| | |
| Strip | Flat rolled slab, which is subsequently supplied in coil form to the automobile and white goods industries |
| | |
| Thinner-Walled Castings | cast components with relatively thin walls. Recent advances in metallurgical quality and alloying have enabled such components to be cast in metal (which would previously have been fabricated in other materials and/or by other methods) |
| | |
| Transfer Ladles | (in foundries or steelmills) a vessel used to transfer molten metal between one process or area and another |
| | |
| Tundish | a refractory holding vessel, with one or more nozzles in the base, used to feed molten steel, in a controlled manner, into the mould(s) of the continuous casting process |
| | |
| Tundish Furniture | a range of highly refractory precast shapes (dams/weirs/baffles/ impact pads) used to control the flow of steel through the continuous casting tundish and assist the removal of inclusions (impurities) from the steel, before transfer to the continuous casting mould |
