The invention discloses a double-furnace-door sealing structure for a vacuum furnace for heat treatment. The vacuum furnace for heat treatment comprises a front chamber and a rear chamber. A heating chamber is arranged in the rear chamber. An opening facing the front chamber is formed in the heating chamber. The sealing structure comprises a middle door sealing structure and a heat insulation door sealing structure. The middle door sealing structure comprises a middle door. The middle door is arranged between the front chamber and the rear chamber. A middle door rubber sealing strip is arranged on the edge of the middle door. The upper end of the middle door is connected with a middle door lifting device. The heat insulation door sealing structure comprises a heat insulation door. The heat insulation door is arranged in the rear chamber and located on an opening of the heating chamber. The surface, facing the heating chamber, of the heat insulation door is covered with a heat insulation heat preservation layer. The upper end of the heat insulation door is connected with a heat insulation door lifting device. A preset mounting space is reserved between the heat insulation door and the middle door.
Description
technical field [0001] The invention relates to a heat treatment device, in particular to a double-door sealing structure of a vacuum furnace for heat treatment. Background technique [0002] Vacuum furnace is regarded as one of the equipments for upgrading equipment in the heat treatment industry. The important reason is that the product parts processed by vacuum furnace have bright surface, less oxidation, good performance and high precision. It is easy to realize energy saving, consumption reduction and reduction in the production and operation of vacuum furnace. It belongs to clean production equipment and meets the requirements of today's environmental protection. There are very few gas molecules in vacuum, and the free path of molecules becomes larger, so light rare metals, refractory metals, rare metals and other special alloy materials that cannot be obtained under normal pressure can be produced. [0003] Vacuum furnaces for heat treatment generally have a double-c...
