Claims9
An apparatus for the off-line drying treatment, or dry out, of an inductor for billets, comprising:
- a coil and a protection body made of refractory material and defining a transit channel for the billets, wherein said apparatus comprises a heating device comprising at least one electric resistance configured to transform the electrical energy received into radiant heat and to act as a false billet, wherein said electric resistance has size and characteristics correlated to the sizes and characteristics of a real billet the inductor be made to pass in the transit channel of the inductor, with an oblong development along a longitudinal axis and located, during use, inside the transit channel of the inductor, a support structure configured to support said resistance cantilevered in such a way that its axis of longitudinal development is oriented substantially horizontally, power supply devices configured to supply electrical energy to said resistance, and a control and command unit configured to command said power supply devices and regulate the functioning of said resistance according to a predefined program.
A method for the off-line drying treatment, or dry out, of an inductor for billets comprising a coil and a protection body made of refractory material defining a transit channel for the billets and arranged to perform said drying treatment outside the rolling line, wherein said method comprises:
- positioning said inductor with said transit channel around a heating device comprising at least one electric resistance configured to transform the electrical energy received into radiant heat and to act as a false billet having sizes and characteristics correlated to the sizes and characteristics of a real billet intended to be made to pass in the transit channel, with an oblong development along a longitudinal axis, and wherein said inductor with its transit channel is positioned coaxial to said resistance which is located cantilevered with respect to a wall of a support structure in such a way that its axis of longitudinal development is oriented substantially horizontally;
- supplying electrical energy to said resistance by means of power supply devices;
- commanding said power supply devices and regulating the electric voltage supply to said resistance according to a predefined program by means of a control and command unit in order to suitably heat said resistance and performing a desired cycle of drying treatment on said inductor comprising successive steps of heating and stabilizing the temperature of said refractory material.
