Abstract
The stabilization of introduction of oxygen into a furnace during the oxidation period in all heats of 08Kh18N10T steel by automatic maintaining the gas pressure in an oxygen line at a level of 14 atm and the use of an oxygen meter make it possible to determine the actual oxygen flow rate; to calculate this flow rate for each experimental heat; to estimate the degree of oxygen assimilation for oxidation reactions as a function of the carbon concentration in a metal at the end of the oxidation period of heat; and to calculate oxygen distribution for the oxidation of C, Si, Mn, and Cr in a metallic solution. The results of measuring emf with oxygen sensors at the beginning, middle, and end of the oxidation period for experimental heats are used to calculate the actual oxygen activities in the metal. In all experimental heats, the oxygen activity increases with decreasing carbon concentration.
