RECYCLING PRACTICES OF SPENT MgO-C REFRACTORIES
The recycling options of spent MgO-C refractories from an electrical arc furnace (EAF) have been evaluated. The economic, quality of spent refractories and products made from it, the ease of implementation of a recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a foaming sla...
متن کاملExpert Systems in the Steel Making Industry
This paper presents three prototypical expert systems that were developed in different fields of the steel making industry. It is described which kind of knowledge has to be represented, what are the techniques required for intelligent reasoning, and why expert systems offer better solutions to the described problems than traditional programming approaches. From the given applications the main ...
متن کاملCenter for Advanced Sustainable Iron & Steel Making
Current blast furnace technology is a two-stage ironmaking process that requires that iron ore concentrate first be formed into pellets, fired at 1260°C, cooled, transported to the blast furnace, and then re-heated to approximately 1500°C to produce pig iron. This heating, cooling, and then reheating wastes a great deal of energy, which would be saved if the ironmaking process had only a single...
متن کاملIN SITU REFRACTORIES USED IN THE CONTAINMENT OF MOLTEN IRON AND STEEL STRATEGIES FOR THEIR DEVELOPMENT
In situ refractories are defined as brick or unshaped products, which react internally or with furnace atmospheres and/or slag components so as to be enhanced in their performance. Examples of such products are discussed with emphasis on those that are currently employed and are being developed for the melting of iron and steel. Some strategies for the development of future in situ products are...
متن کاملTHERMAL SHOCK OF REFRACTORIES
Being brittle and having low thermal conductivity, refractories suffer damage and sometimes fail in service as a result of thermal shock. While the approach of those making fine-grained technical ceramics is to make their products sufficiently strong to withstand thermal stresses the refractory technologist is more cunning. He uses, often little known, devices to provide resistance to thermal s...
