[0002] The furnace shell of a high-temperature furnace is generally formed by welding the furnace barrel, the head, and the flange. In addition, other components are welded in the furnace barrel, such as guide rails, exhaust pipes, support tubes, gas charging tubes, electrode tubes, etc. However, welding deformation often occurs during the welding process, resulting in dimensional deviations. However, for high-temperature furnaces with high precision requirements, welding deviations often cause the furnace shell to be unable to be installed normally with other components, thus affecting the normal operation of the equipment. The support tubes in the furnace barrel have the largest number of welds, and their function is to support the graphite platform. Welding deviations ultimately make the graphite platform plane poor, which can easily cause the graphite support column to break. Utility Model Content
