Advanced automated complex using induction and resistance furnaces for precise heating of the titanium billets

Abstract

The automated complex is developed for precise heating of cylindrical titanium billets with various length and diameter. The high homogeneity temperature field of the billet is reached during the heating process. Achievement accuracy of the final temperature is $5\div 10\ {}^{\circ}\mathbf{C}$. Billets of $400\div 750$ mm length and 165-275 mm diameter are exposed to heating. The heating cycle of billet in the inductor and the resistance furnace includes high-speed heating in induction heater and endurance of billet in the resistance furnace. Temperature control of a billet surface is made by means of a pyrometer located over a surface of billet in the middle of the inductor. Billet transportation from the induction heaters store and then into the resistance furnace is made by means of carts in automatic and manual modes.
