Abstract

The invention relates to a heat treatment device, which is characterized in that it comprises: a first linear furnace and a second linear furnace, respectively having an input end and a discharge end; crawlers, which run through the first linear furnace and the second connected to the linear furnace; at least one trolley, which moves along the crawler belt, can pass through the first linear furnace and the second linear furnace, and load the material to be processed; and a gas supply part, which is connected to the table The car is connected and supplied with gas. Therefore, the present invention can eliminate the area for supplying excess heat, effectively use heat energy, and prevent temperature deviation, thereby further improving product quality.

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 ...
