Problems solved by technology

[0004] In the above-mentioned related technologies, the inventor believes that: when the seamless pipe is heat-treated, since the flame injection mechanism is located above the seamless pipe, the seamless pipe is transported by the seamless pipe conveying device, and the seamless pipe is far away from the flame injection. The temperature difference between the side of the mechanism and the side facing the flame injection mechanism is relatively large, which makes the heat treatment quality of the seamless pipe poor

Abstract

The invention relates to the technical field of heat treatment equipment, in particular to a heat treatment device for large-diameter high-temperature corrosion-resistant alloy seamless tube production. The heat treatment device comprises a furnace body, a heating mechanism arranged in the furnace body and a conveying mechanism arranged in the furnace body and used for conveying a seamless tube, rotating rollers positioned on the two sides of the seamless tube are rotationally arranged in the furnace body, a sliding assembly for driving the rotating rollers to slide and a driving assembly for driving the rotating rollers to rotate are arranged in the furnace body, and the sliding assembly is used for driving the rotating rollers to slide to jack up the seamless tube and separate the seamless tube from the conveying mechanism. According to the heat treatment device, the rotating rollers are arranged, the seamless tube is jacked up after the rotating rollers abut against the seamless tube through the sliding assembly, so that the seamless tube is separated from the conveying mechanism, and then under driving of the driving assembly, the rotating rollers rotate to drive the seamless tube to rotate, so that the side, away from the heating mechanism, of the seamless tube can also rotate to be close to the heating mechanism to be heated, the temperature difference of heating of the upper side and the lower side of the seamless tube is reduced, and therefore, the heat treatment device has the advantage of improving the heat treatment quality of the seamless tube.

Description

Technical field [0001] The present application relates to the technical field of heat treatment equipment, and more particularly to a large diameter high temperature resistant alloy seamless pipe production heat treatment device. Background technique [0002] At present, during the process of processing seamless steel tubes, heat treatment annealing is one of the indispensable steps, mainly for releasing stress, increasing the ductility and toughness of seamless steel pipes, and treats seamless steel pipes. Easy to adjust the diameter of the seamless steel pipe.
