Abstract

The article presents the concept of refining with the use of slag activated with carbide coating. It pointed out the important role of stimulators of ionic reactions. The results of research from the melting of the CuAl10Fe4Ni4 alloy obtained from recycled materials in metallurgical conditions were shown. The changes in the structure of the alloy depending on the nature of the used simulators were indicated. Chemical reagents used and the stimulants in the form of haloids helped to improve the molding sand exchange process. The use of chemical regent in the form of calcium carbide and stimulants has also contributed to the formation of a protective atmosphere in the furnace bottom.
