A method of using an oven includes supporting a substrate on a rotatable spindle in a processing chamber of the oven and rotating the substrate. The method may also include raising the spindle with the substrate to a heating zone and activating a lamp assembly to heat a top surface of the substrate. The substrate may then be lowered to a dosing zone and a chemical vapor directed into the processing chamber above the substrate. The substrate may then be further heated using the lamp assembly and cooled.

A furnace for producing a secondary battery cathode material according to an exemplary embodiment of the present invention includes; a chamber of which the internal space is heated by a heater; a conveyer installed in the chamber and conveying a sagger containing raw material power of a cathode material of a secondary battery in one direction; and a gas supply nozzle and an exhaust port installed in the chamber.

The chamber is divided into a front chamber, an intermediate chamber, and a rear chamber. The intermediate chamber has an inlet shutter and an outlet shutter for sealing the internal space thereof, and an exhaust port of the intermediate chamber is connected to an exhaust device for discharging gas.

A method and plant for thermally treating braking elements after a forming step, including a convective heating step at 150-300 C. and a infrared irradiation heating step, immediately in succession one relative to the other. A tunnel convection furnace is crossed by at least a first conveyor belt which translates along a first direction and on an upper face of which the braking elements are placed, is arranged laterally adjacent, with respect to the first direction, to an infrared heating tunnel furnace crossed by a second conveyor belt which translates along a second direction, parallel and opposite to the first one, and on an upper face of which the braking elements are placed. The first conveyor belt is larger than the second conveyor belt, and the braking elements appear in multiple side-by-side rows in a transverse and oblique direction with respect to the first and second directions. Robots placed at the opposite ends of the furnaces transfer the braking elements from the first conveyor belt to the second one or vice versa to a first end of the furnaces and place them on the first conveyor belt or second one to a second end of the furnaces being opposite to the first one, so as to change at will the sequence in which the infrared and convective heating steps are performed.

A reflow oven includes a chamber housing including surfaces that are in contact with heated air mixed with contaminants, including flux, and a water-soluble layer selectively applied to the surfaces of the chamber housing. Embodiments of the reflow oven include an acrylic-based layer, such as an acrylic paint. In one embodiment, the acrylic paint includes a water-soluble polymer, a polymer emulsion, and water. The water-soluble polymer includes butyl benzyl phthalate. In some embodiments, the acrylic paint includes 1-10% by weight butyl benzyl phthalate, 30-55% by weight acrylic polymer emulsion, and balance water. In a certain embodiment, the acrylic paint includes 1-5% by weight butyl benzyl phthalate, 35-50% by weight acrylic poly emulsion, and balance water. Methods of treating surfaces of the reflow oven are further disclosed.
