In electric arc furnace steelmaking units, the essential parameters are reducing price, increasing production and decreasing environmental pollution. Electric arc furnaces are the largest users of electric energy in industry. The most important techniques that can be used to reduce the electric energy consumption in electric arc furnaces are scrap preheating, stirring, use of burners and hot ch...

Due to increased competition in a world economy, steel companies are currently interested in developing techniques that will allow for the improvement of the steelmaking process, either by increasing output efficiency or by improving the quality of their product, or both. Slag foaming is one practice that has been shown to contribute to both these goals. This paper describes an effort in progre...

Issue: Processed recycled glass has been sold as an abrasive blasting medium under several brand names in different parts of the United States. However, limited public information is available regarding the performance of finely sized crushed glass in abrasive applications because manufacturers have developed their own proprietary data. Historically, the predominant material used for abrasive b...

For the measurements 19 samples of building materias used in construction activities in this region of India were collected from various sites. In the present investigations radon exhalation rates from some building materials like fly ash, cement, slag, Bottom ash, Sand, Bazari, Badarpur and flooring tiles have been estimated using sealed can technique. It can be observed that Radon activity, R...

The most important component of steelmaking slags is the iron oxide since it serves as the oxidizing agent in refining reactions. The measurement of the iron oxide content is performed in the steelworks by taking a sample out of the liquid slag, cooling it and subsequently analysing it. The procedure takes some time. It would be highly desirable, therefore, to develop methods for rapid in situ ...

This paper studies the influence of assembly unit expansive agents (CaO and calcium sulphoaluminate) on limited free compressive strengths, expansion rate, carbonation resistance, chloride ion penetration resistance corrosion reinforcement concrete. The dosages agent were 0%, 3%, 6%, 9%, 12% by total amount cementitious materials. Two kinds mineral admixture (blast furnace slag fly ash) applied...
