Description

Technical Field

[0001] The utility model relates to the technical field of annealing furnaces, in particular to a bright annealing furnace for heat treatment of metal strips. Background Art

[0002] Most bright annealing furnaces are composed of the following parts: (1) a heating chamber, where the workpiece is heated to the required annealing temperature and continuously moves forward. For example, for copper tubes, it is approximately 800 degrees, and for stainless steel tubes, it is about 1100 degrees; (2) a cooling chamber, where the workpiece heated in the heating chamber is gradually cooled and reaches a preset temperature, such as about 80 degrees; the workpiece coming out of the cooling chamber is then moved forward by the production line, and the bright annealing furnace for heat treatment of metal strips is one type of annealing furnace.

[0003] At present, although the bright annealing furnace for heat treatment of metal strips is designed with a heating plate, a control box, and a touch panel, during use, the device operates the control box by controlling the touch panel, thereby heating the heating plate to heat the internal processing material. However, during use, since the material needs to be heated at a high temperature, an oxidation reaction will occur on the metal surface during the heating process, thus reducing the quality of the processed metal. At the same time, a large amount of high-temperature gas is generated when the existing bright annealing furnace for heat treatment of metal strips cools the metal, and the existing device cannot utilize the internal heat energy, resulting in a large amount of wasted heat energy.
