Abstract
The invention discloses a device and method for performing heat treatment under water, comprising a heat treatment chamber with an open lower end, a first gas passage, a second gas passage, a high-temperature sealing ring, an annular metal plate, a hydraulic module, a heating module, a column Plug, pressure sensing module, temperature measurement feedback module, oxygen monitoring module, the heating module is arranged on the inner surface of the heat treatment chamber. After the heat treatment chamber reaches the surface of the underwater heat treatment workpiece, the hydraulic module pushes the annular metal plate through the plunger to extrude the high-temperature sealing ring to realize the sealing of the underwater heat treatment workpiece. The invention can heat treat the metal at the underwater welding repair according to the set heat treatment process, reduce the hardenability of the welding repair position, prolong the service life of the repaired workpiece, shorten the operation time and reduce the operation cost, the whole process is automated, and the operation is simple and convenient. sex.
Description
technical field [0001] The invention relates to the field of heat treatment equipment, in particular to a method and device for performing heat treatment under water. Background technique [0002] Heat treatment is an important part in the production process of metal workpieces. Through heat treatment, the structure type and morphology of metal materials can be changed, the residual stress inside the workpiece can be adjusted, the machinability of materials can be improved, and the mechanical properties required by metal workpieces can be improved. Accurately grasping the heat treatment process of workpieces and maximizing the performance of metal workpieces can maximize the service life of workpieces and equipment and create huge social and economic value. The heat treatment process mainly includes four fires, namely normalizing, annealing, tempering, and quenching. The temperature and time of the four fires are determined according to different material properties and phas...
