Possibilities of Controlled Reduction of Chromium from the High-chromium Slag in Production of Steels

Original language description

This text presents possibilities of controlled reduction from high-chromium slag under operating conditions in EAF in the production of high-chromium steels. A proper proposal of the operational technology results from theoretical knowledge of reduction of chromium oxides from slag using different reduction agents, and from the method of application and modification of the melting technology in the production of high-chromium steels in EAF. The above mentioned theoretical knowledge was completed by the results of the study of Cr2O3 reduction from slag into steel under laboratory conditions using different reduction agents and methods of application. On the basis of theoretical knowledge and results of the laboratory experiments the technology for conditions of the EAF No. 5 of VÍTKOVICE HEAVY MACHINERY a.s. was proposed. Within the above-mentioned technology, a prototype of the slag controlled reduction device will be used that enables dosing of the reduction agent onto the slag surface in order to reach high-chromium slag controlled reduction.
