A tunnel oven and associated method for the heat treatment of friction elements, and in particular braking elements such as brake pads is provided. The friction elements are arranged on a resting surface of a conveyor device, are moved between an inlet opening and an outlet opening of the tunnel oven, and are heated by irradiation by at least one heating device. The heating device includes a radiating plate made from stainless steel arranged facing the conveyor device and heated by electromagnetic induction using at least one inductor arranged facing the radiating plate and spaced apart therefrom on the side opposite to the conveyor device. A cooling air flow for the braking elements between the resting surface and the radiating plate is directed in counterflow to a feeding direction of the conveyor device.

A furnace for annealing a sheet includes: a first section; a second vertical section, the second vertical section including openings supplied with an oxidizing medium, an opening facing each side of the sheet, and means for separately controlling a flow of the oxidizing medium on each side of the sheet; and a third section. The second vertical section is located in a distinct casing and separated from the first and third sections with sealing devices. The second vertical section includes extraction openings for extracting the oxidizing medium not consumed by the sheet, an extraction opening facing each side of the sheet. The openings supplied with an oxidizing medium are located transversally at one end of the second vertical section. The extraction openings are located transversally at an other end of the second vertical section.

A method for the thermal treatment of mineral raw materials such as limestone or dolomite is shown and described, which includes at least the following steps of a. providing a mineral bulk material and a conductive material and b. placing the mineral bulk material and the conductive material into a kiln, generating an electromagnetic field inside the kiln, thermally treating the mineral bulk material in the kiln by means of electromagnetic excitation of the conductive material in the electromagnetic field, and removing the thermally treated mineral bulk material and the conductive material from the kiln. Using the method described, even large quantities of mineral bulk material can be efficiently converted.

The present invention generally relates to a heating apparatus, method of using and making the same that can be used to heat a thermoformable prosthetic socket.

The invention relates to an industrial autoclave used for curing rubber. The autoclave includes a hollow outer body for receiving a product. It also includes a pair of oil-based heat exchangers which are disposed in passageways defined by a pair of ducts. The heat exchangers are connected in parallel to one another in fluid flow communication to a supply of heated oil. Each heat exchanger includes a plurality of serially interconnected, parallel finned radiators which allow passage of the oil therethrough facilitating heat transfer to air passing over the radiators. A fan ensures air circulation. This autoclave is a non-pressurized system with very little wear properties, no risk of fire, no need for a condensate tank and no water treatment is required. In addition, a considerable saving in terms of power consumption is made when compared to electrical autoclaves.

An induction oven for the sterilization of equipment is disclosed. The invention effectively reduces sterilization cycle times from 90 minutes to less than 30 minutes using dry heat. In addition to increased efficiency, the dry heat also avoids pitting and other forms of degradation of the materials being sterilized. The oven can be configured by the user to generate a resonance of a particular frequency to target the specific type of metal or other induction material being heated. Target induction materials include cast iron, stainless steel, brass, and graphite, for example. The oven includes a coil that generates the time-varying electromagnetic field using a two-dimensional spiral having a rectangular pattern. The spiral coil is formed on a printed circuit board. The oven is configured to receive a container for heating articles. The container includes a bin, e.g., aluminum, and transparent lid with a gasket therebetween to produce an airtight seal. The container can be used to both sterilize equipment as well as store the sterilized equipment without contamination.

A hot air flow direction control mechanism of a base board baking machine includes a stand, a controller, a housing, a hot air device, an air suction unit, and a top cover. Thus, the hot air device blows the hot air into the housing, and the air suction unit sucks the hot air so that the hot air is circulated evenly in the housing and around the periphery of the housing.

A tunnel oven and associated method for the heat treatment of friction elements, and in particular of braking elements such as brake pads is provided. The friction elements are arranged on a resting surface of a conveyor device, are moved between an inlet opening and an outlet opening of the tunnel oven, and are heated by irradiation by at least one heating device. The heating device includes a radiating plate made from stainless steel arranged facing the conveyor device and heated by electromagnetic induction by means of at least one inductor arranged facing the radiating plate and spaced apart therefrom on the side opposite to the conveyor device. A cooling air flow for the braking elements between the resting surface and the radiating plate is directed in counterflow to a feeding direction of the conveyor device.
