The economical, safe and environmentally responsible operations of EAF's are key elements of modern steel melting technology. SMS Group has developed various technologies for increasing and optimizing the performance of EAF's for scrap, DRI and hot metal based operations. These technologies can be applied to new plants as well as revamps and modernization projects of existing furnaces and often unite profitability with safety, such as for the automatic slag door Condoor® , the anthropomorphic robot for temperature and sampling or the automatic cleaning and opening of the EBT tap hole. In other cases they unite profitability with eco-sustainability such as, for example, with efficient fume treatment plants and off-gas energy recovery, dynamic furnace control via FEOS (Furnace Energy Optimization System) linked with off-gas analysing and burner control of chemical packages optimized for both scrap or DRI based furnaces.

A great deal of effort is being taken to make the electric arc furnace as safe as possible with the least possible need for operator intervention. The main cause of accidents for electric arc furnace (EAF) operators during production is the splashing of hot material caused by violent reactions, or explosions, mainly due to water leaks. Besides this kind of casualty, which is closely related to the melting process, many other types of accidents are common in other manufacturing industries and are related to falling loads, collisions with traveling cranes, transfer cars or forklifts, and falls from buildings. Costs for achieving safety have been an obstacle because they are not compared to costs of accidents once they occur. Little regard for the safety of workers has been 'justified' from the economic point of view, and thus there has been little protection from the law, a low level of welfare and the availability of a high number of low-skilled operators.

The basic idea of a minimill is the production and processing of steel for long products in an integrated factory. The hot billets from the caster are fed through an induction heating system directly into the rolling mill. The induction system detects the billet's incoming temperature and equalizes the surface and core temperatures on demand, in order to provide an optimum rolling temperature. Important to notice with regard to the sustainability is the fact, that no fossil fuel combustion furnace is needed. This setup allows for significant energy and cost savings and causes less emission. The article describes the energetic and economic advantages of induction systems integrated in minimills and, as an example, refers to a proven solution at Tung Ho Steel in Taiwan. Source

The invention relates to a furnace slag door, comprising at least one panel which is moveable, in a mounted state of the slag door, from an opened position, in which the panel is remote from a corresponding slag discharge opening within the furnace wall to a closed position, in which the panel covers at least part of said slag discharge opening. The invention further comprises a corresponding furnace equipped with such slag door. The furnace is, in particular, an electric arc furnace (EAF) but may be as well of another type.


A building is provided with a hood for drawing fumes produced in a metallurgical environment, comprising: a main hood body defining a hood conduit having a decreasing cross-section between an inlet and an outlet openings for the fumes coming from the metallurgical environment; a header for collecting fumes coming from the outlet opening of the main hood body; one or more pipes for conveying fumes outside said header. Portions of said main hood body form walls of said one or more pipes.
