Abstract

Laboratory experiments were carried out to test the electroslag remelting of corrosion-resistant titaniumalloyed steel using AKF235 low-silicon flux. The titanium loss in these experiments was compared with the available literature data on titanium loss in similar steels during electroslag remelting using ANF-29 high-silicon flux. It is shown that the use of AKF235 flux reduces the titanium loss if all the other conditions (content of titanium dioxide in slag and slag deoxidation conditions) are equal. If the content of titanium dioxide in the starting flux is 2.5%, the titanium loss is practically suppressed by a sufficient amount of deoxidizers added to the slag: 6 g Al and 1.5 g Ti per 1 kg of melted metal. Reducing the weights of added deoxidants to 3 g Al and 0.5 g Ti per 1 kg of melted metal, as well as reducing the content of titanium dioxide in the slag increase the titanium loss.
