ABSTRACT:
A method and oven equipment for cooling a charge after thermal treatment. The charge, which is located within a closed chamber, is cooled by blowing in cooling gas. The cooling occurs as a function of the actual conditions of the charge at a predetermined speed, and a uniform distribution of temperature within the charge is assured. For this purpose, the temperature distribution in the charge is measured by temperature sensors, and the intensity and/or direction of the flow of the cooling gas can be changed if deviations from the predetermined theoretical values occur. The wall of the closed treatment chamber of the oven equipment contains a plurality of gas passages which can either be closed off, or are permeable for gases yet impermeable for heat rays. Cooling gases are conducted through the chamber via control valves. The cooling gas is circulated with the aid of a blower unit along with a gas cooler. A temperature control system based on desired-actual-comparisons operates the control valves and the closure elements of the gas passages.
