Description

Technical Field

[0001] The utility model relates to the field of heat treatment, and more specifically, to a stainless steel pipe heat treatment device. Background Art

[0002] Stainless steel pipes often use heat treatment processes to improve their mechanical properties during production. Quenching of stainless steel pipes is a common heat treatment method. Quenching of stainless steel pipes is to heat them to austenite temperature and then quickly cool them with cooling water or cooling oil to achieve the effect of improving mechanical properties.

[0003] The existing stainless steel pipe quenching usually involves throwing the heated stainless steel pipe into a cooling pool for cooling. However, the existing cooling pool is not convenient for salvaging the cooled stainless steel pipe, which easily leads to accumulation of steel pipes and reduces the production efficiency of stainless steel pipes. There are also some quenching equipment that cools and quenches stainless steel pipes by spraying coolant, but the position and angle of the stainless steel pipes on these equipment are often fixed, which may cause uneven cooling, thereby reducing the product quality to a certain extent.

[0004] Therefore, a solution needs to be proposed to solve this problem. Utility Model Content

[0007] By adopting the above technical solution, when quenching the stainless steel pipe, the heated stainless steel pipe is placed between two supporting rollers, and the conveyor drives the stainless steel pipe to move to the side of the discharge port through the supporting rollers. In this process, the sprinkler nozzle sprays coolant on the stainless steel pipe to quickly cool it down and quench it.
