Refractories for Electric Arc Furnace

Ghosh, B N (1994) Refractories for Electric Arc Furnace. In: UNSPECIFIED.



Since the first commercial application for steelmaking in 1903, Electric Arc Furnace has been considered as a versatile equipment for production of Steel. It was initially caused for making high quality steels e.g. Stainless steel etc. with high cost of production. However, with the development in the engineering and technology after World War-II, cost of production through this route has become very competitive and production through this route started growing constantly. The annual growth rate has been indicated as 2.5 - 3% currently and a world production level of around a billion tone is expected by the turn of the century. The increase in the share of EAF steelmaking process has been made possible because of introduction of furnaces with large capacity, availability of power at a comparatively lower rate and also the change in process technology which has allowed to use various types of input material. However, with high power rating in the furnaces, the conditions towards the refractory became very severe. Continuous development in Refractories technology as well as in the process engineering, specific consumption of refractories gradually came down. Further in many areas, use of refractories materials have been replaced or minimised with the introduction of water cooled panels.
