[0002] Seamless steel pipe refers to a steel pipe made by perforating a whole round steel with no welds on the surface. Seamless steel pipe has a hollow cross-section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water and certain solid materials. Seamless steel pipe needs to be heat treated during the production process to change the characteristics of the seamless steel pipe so that it meets the required requirements.

[0003] When heat treating a seamless steel pipe of a shorter length, the existing method is usually to place the seamless steel pipe directly in a heat treatment furnace and perform heat treatment on the seamless steel pipe. The heat treatment furnace can perform heat treatment on multiple seamless steel pipes at the same time, thereby improving the heat treatment efficiency of multiple seamless steel pipes. The heat treatment furnace is simple to use and convenient for staff to operate. However, in the above method, the bottom of the seamless steel pipe is in contact with the movable plate of the heat treatment furnace, and the movable plate of the heat treatment furnace has no heat source, resulting in inconsistent heat treatment effects between the side wall and the bottom of the seamless steel pipe, thereby reducing the heat treatment effect of the seamless steel pipe.

The multiple lifting rods 47 drive the pulling cylinder 481 to be removed from the seamless pipe fitting. At the same time, the spring telescopic rod 401 drives the impurity removal roller 403 to separate from the seamless pipe fitting through the strip plate 402. Then, the rectangular plate 33 is pressed down by the existing pressing equipment. The rectangular plate 33 drives the four rack rods 32 to move downward and push the corresponding transmission gear 37. The transmission gear 37 drives the placement semi-ring 38 to rotate through the rotating rod 36. The two placement semi-rings 38 on the same side rotate relative to each other, thereby dumping the impurity scabs that fall off the placement semi-ring 38 into the collection frame 6, thereby centrally collecting the impurity scabs to avoid affecting the surrounding environment, and the heat treatment is completed.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
