Effect of Stabilizing Steel Temperature in a Continuous-Caster Tundish by the Plasma Method on the Uniformity of the Mechanical Properties of Plates After Rolling

method is described for the plasma heating of steel in the tundish of a continuous caster. Results are presented from studies of the mechanical properties of rolled products made of steel that was cast after being heated above the liquidus temperature by different amounts. The degree of superheating of the steel was stabilized by having it undergo plasma heating in the tundish. Tests of rolled products of continuouscast steel showed the positive effect of its plasma heating.
