Description

Technical Field

[0001] The utility model belongs to the technical field of ship diesel engine production, and in particular relates to a heat treatment supporting base for a ship diesel engine. Background Art

[0002] Residual stress will be generated in the welding and cold processing of marine diesel engine parts. The residual stress will be slowly released during the use of the product, affecting the stability of the product structure.

[0003] At present, after welding, residual stress is usually eliminated by heat treatment such as annealing in the frame or base of a marine diesel engine. However, since the floor of the heat treatment furnace is made of refractory bricks, cracks will occur during long-term use, resulting in an uneven floor. When the frame, base and other parts of the marine diesel engine are placed in the heat treatment furnace for annealing, point contact is easily formed between the parts and the floor of the heat treatment furnace, causing deformation of the parts during the annealing process, which seriously affects the flatness of the parts.

[0004] In addition, the existing heat treatment support device cannot achieve the heat conduction in the heat treatment furnace, which makes it easy for heat to accumulate, resulting in uneven local heating of parts and components, further causing deformation of the parts. Utility Model Content
