Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel castings, in particular to a high-stability and high-temperature resistant stainless steel casting. Background Art

[0002] Stainless steel castings are made of fusible materials to form a fusible model, on which several layers of special refractory coatings are coated. After drying and hardening to form an integral shell, the model is melted from the shell with steam or hot water, and then the shell is placed in a sand box, and dry sand is filled around it. Finally, the mold is placed in a roasting furnace and roasted at high temperature. After the mold or shell is roasted, molten metal is poured into it to obtain a casting. High temperature resistant stainless steel castings are often used to transport high-temperature fluids.

[0003] A high-temperature resistant stainless steel casting is proposed in the utility model patent with the Chinese patent announcement number CN218883344U. It utilizes the set welding top plate, internal heat conduction plate, heat sink fin mounting base, docking base, heat sink fin body and locking mechanism to facilitate the installation of a heat sink fin body on the top of the stainless steel casting body to dissipate heat from the stainless steel casting body, so that the stainless steel casting body is resistant to high temperatures, has good heat dissipation, and is not easily damaged or aged.

[0004] However, this type of high temperature resistant stainless steel casting requires additional welding processing, which makes the assembly of the casting time-consuming. On the other hand, the heat sink fins are only fixed in one direction, which makes the heat sink fins easy to fall off due to collision or vibration. Utility Model Content
