SECONDARY ELECTRO-THERMAL ALLOYING AND AFFINAGE OF METAL
WITH PARTICIPATION GAS PHASE
Zaporozhe state engineering academy
There is presented the study of the influence of the specific charge for slag on the
pressure of the gas phase, the content of impurities and alloying elements in the process
of secondary electro-thermal alloying and refining (SEAR). It was established that the
increase in external pressure can significantly increase the efficiency of doping-steel
alkaline earth metals due to reduced their loss in the gas phase. The main SEAR
parameters for low-alloy steels have been determined.
Keywords: steel, alloying, refining, gas phase, thermodynamics, calcium, magnesium.
