Ferroalloy industry waste processing

Abstract

In order to develop a technology and equipment for remelting waste from the ferroalloy industry, the Yurga ferroalloy plant gives 1500 kg of ferrosilicon waste to “Sibelektroterm” for experimental smelts and formulation of technical requirements for new remelting equipment. The findings of these operations are presented in this article. The results of experimental ferroalloy waste processing smelts in a direct-current furnace with the power of 140 kW are examined; parameters of three-phase electric furnaces of alternating current with power 0.63-6.3 MV·A and technologies of ferroalloy waste processing are examined. In addition, original characteristics of the waste are considered. Remelting of ferrosilicon waste in three-phase alternating current furnaces is considered.
