New Electroslag Furnaces Abroad

Abstract

The achievements of the modern steelmaking industry are largely due to the development of highly efficient methods of so-called secondary metallurgy, such as ladle (furnaceless) metallurgy, which have improved the quality of a large variety of steels. At present, the degree of molten steel purity is comparable to or even higher than that which earlier could be achieved only by remelting pro­cesses. Nevertheless, electroslag remelting (ESR) is still of great importance, as are other remelting processes. These technologies are used to produce high-quality steels having a high purity, density, and homogeneity. Increases in the purity of the initial alloy have yielded further improvements in the quality of ESR steel. This is currently the main development direction in world metallurgy.
