[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: A heat treatment device based on seamless steel pipe processing and production, such as Figure 1-Figure 5 As shown, it includes a heat-conducting roller 1 and a rotating motor 2 installed on one side of the heat-conducting roller 1. The heat-conducting roller 1 is installed at the output end of the rotating motor 2. A resistance heating rod 3 is rotatably installed inside the heat-conducting roller 1. The resistance heating rod 3 extends out of the outside of the heat-conducting roller 1, and a wire 4 is installed at the end of the resistance heating rod 3 away from the rotating motor 2. One wire 4 is fixedly connected to several resistance heating rods 3. A horizontal guide tube 8 is installed between two adjacent heat-conducting rollers 1. Several ignition heads 9 are installed on the outside of the horizontal guide tube 8. An arc-shaped guide tube 10 is installed on the outside of the horizontal guide tube 8. The arc-shaped guide tube 10 is connected to the inside of the horizontal guide tube 8. Several auxiliary heads 11 are installed on the outside of the arc-shaped guide tube 10. The horizontal guide tube 8 and the arc-shaped guide tube 10 operate as a group, and several horizontal guide tubes 8 are fixedly connected to a conduit 12 at the same time.

[0026] When the device is in use, first, the rotating motor 2 is controlled to run, driving the rotating motor 2 to rotate at the same time, and the seamless steel pipe is placed on the upper end of the heat-conducting roller 1. Based on the rotation of multiple heat-conducting rollers 1, the seamless steel pipe is driven to move. At the same time, the resistance heating rod 3 is energized to supply heat to heat the heat-conducting roller 1 itself, and then the outer fuel is circulated through the horizontal guide tube 8 and the arc guide tube 10, and is respectively guided to the ignition head 9 and the auxiliary head 11. Then, under the ignition of the ignition head 9 and the auxiliary head 11, the fuel is burned to heat the outside of the seamless steel pipe, and the heating temperature of the heat-conducting roller 1 and the seamless steel pipe is adjusted to be consistent to ensure uniform and comprehensive mobile heating of the material. By controlling the rotation speed of the rotating motor 2 and the combined use of multiple heat-conducting rollers 1, the horizontal guide tube 8, and the arc guide tube 10, the seamless steel pipe is heated synchronously while moving slowly, and then moved to the insulation and cooling link, so that the device can perform heat treatment while moving the material, thereby improving the efficiency of the device in processing seamless steel pipes.

[0027] like Figure 1-Figure 5 As shown, a connector 5 is installed on the outside of the wire 4, and a connecting tube 13 is installed on the outside of the conduit 12.

[0028] With the support of the connection between the connecting head 5 and the external current, the accurate heating of the resistance heating rod 3 is guaranteed. With the supply conduction between the connecting pipe 13 and the external gas fuel, the stable heating supply to the auxiliary head 11 and the ignition head 9 is guaranteed, further improving the efficiency and uniformity of the uniform heating of the device.

[0029] like Figure 1-Figure 5 As shown, a limiting cover 7 is installed on the outer side of the arc-shaped guide tube 10 , and the arc-shaped guide tube 10 is installed on the inner wall of the limiting cover 7 .

[0030] The heat-conducting roller 1 is rotatably mounted inside the limiting cover 7 . Several limiting rings 6 are mounted outside the heat-conducting roller 1 . The heat-conducting roller 1 extends to the outside of the limiting cover 7 . The rotating motor 2 is mounted outside the limiting cover 7 .

[0031] The resistance heating rod 3 and the horizontal guide tube 8 both extend out of the limiting cover 7 , and the conduit 12 and the wire 4 are both located outside the limiting cover 7 .

[0032] First, under the arc-shaped limitation of the limiting cover 7, the heat generated inside it is concentrated to ensure the full application of the heat. At the same time, the stability of the arc-shaped heating part is guaranteed, and under the guide limitation of multiple limiting rings 6, the position of the seamless steel pipe is guaranteed to be accurate when placed and moved. When the device heats multiple materials at the same time, it can play a role in mutual isolation, further improving the accuracy of the material placement position when the device is heating.

[0033] like Figure 1-Figure 5As shown, the outlet of the ignition head 9 and the outlet of the auxiliary head 11 are located at corresponding positions, and the auxiliary head 11 is distributed in an arc shape, while the ignition head 9 is distributed horizontally.

[0034] By distributing the auxiliary heads 11 in an arc shape, the effect of uniformly heating the outside of the material is further improved. The ignition heads 9 are then set at the same horizontal position, and the ignition heads 9 at different positions are set in different directions to ensure the effect of heating the lower half of the outside of the material at different angles, thereby comprehensively ensuring the stability of the heat treatment of the material.

[0035] Working principle: First, control the operation of the rotating motor 2, drive the rotating motor 2 to rotate at the same time, place the seamless steel pipe on the upper end of the heat-conducting roller 1, and drive the seamless steel pipe to move based on the rotation of multiple heat-conducting rollers 1. At the same time, energize the resistance heating rod 3 to supply heat to heat the heat-conducting roller 1 itself, and then guide the outer fuel through the horizontal guide tube 8 and the arc guide tube 10 to the ignition head 9 and the auxiliary head 11 respectively. Then, under the ignition of the ignition head 9 and the auxiliary head 11, the fuel is burned to heat the outside of the seamless steel pipe, and the heating temperature of the heat-conducting roller 1 and the seamless steel pipe is adjusted to be consistent to ensure uniform and comprehensive mobile heating of the material. By controlling the rotation speed of the rotating motor 2 and the combined use of multiple heat-conducting rollers 1, the horizontal guide tube 8, and the arc guide tube 10, the seamless steel pipe is heated synchronously while moving slowly, and then it is moved to the insulation and cooling links.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
