In a substrate pre-baking device, a baking box housing includes a baking chamber in an interior space of the baking box housing, wherein an opening corresponding to a side door is arranged on a lateral side of the baking box housing. The side door is arranged at the opening of the baking box housing. A heating structure is arranged in the baking chamber. A hot air curtain device is arranged at the side door of the baking box housing. When the side door is opened, the hot air curtain device is configured to form a hot air curtain for isolating the baking chamber from outside environment at the opening of the side door.

The invention relates to a chamber (1) for the controlled oxidation of metal strips in a furnace for annealing a continuous production line of strips which are hot-coated, for example by galvanisation, the oxidation chamber allowing the oxidation of the metal strips by means of an oxidising gas injected on at least one of the faces of a strip (15), the oxidation chamber comprising oxidation portions (17) extending over the width and/or length thereof, each portion comprising at least one blow opening (4) and at least one suction opening (5) between which an oxidising gas circulates, each portion being controllable in a different way so as to adjust the oxidation induced on the strip over the width and length of the oxidation chamber.

The present invention relates to improvements to an induction smelting process. It relates to a hybrid combination of plasma over induction for a superefficient continuous smelting process; and real-time monitoring and adjustment of the smelting process. Disclosed is a hybrid smelting system comprising a real-time controller and a reduction zone in which plasma over induction heating continuously smelt feed material(s) fed into the reduction zone. Slag and reduced metals (alloy) are discharged under supervision of the real-time controller.
