Abstract
Description
technical field
[0001] The present invention relates to a heat treatment device equipped with a pair of linear furnaces and a collector ring (ring header), and more specifically relates to a device that can reduce heat loss and prevent temperature deviation compared with curved furnaces, thereby improving product quality. A pair of linear furnaces and a heat treatment unit for slip rings. Background technique
[0002] For example, a heat treatment device for steel plates loads materials to be processed (for example, coils, etc.) on the floor of a trolley running on a circular crawler, covers it with a muffle furnace, and conveys it in a ring-shaped furnace.
[0003] The ring furnace has a heating zone with loading doors and a cooling zone with recovery doors. In the furnace, the trolley moves section by section, so that the material to be processed is heated to a specified temperature in the heating area, and the temperature is maintained. Afterwards, when the material to ...
