[0022] The embodiment of the present application provides a device for manufacturing a crystallizer partition of a continuous casting machine, which effectively solves the problem that if preheating is not performed, uneven heating and cooling during welding will cause large thermal stress and residual stress to the metal plate. These stresses will cause deformation of the metal plate, affecting the dimensional accuracy and appearance quality of the welded structure. Two stabilizing tubes are installed through the side ends of the welding module, and at least two flame heads are arranged at the bottom end of the stabilizing tube. The multiple flame heads are equidistantly arranged at the bottom end of the stabilizing tube. A connecting tube is installed at the top end of the mounting plate, and the connecting tube pushes fuel into the interior of the stabilizing tube. The welding end of the partition body is preheated by the flame head, and the splashing flame heats the welding end. Preheating can increase the overall temperature of the partition body before welding, and reducing thermal stress can effectively reduce welding deformation, make the heat affected zone structure more uniform during welding, and reduce the formation of hard and brittle structure, thereby improving the strength of the welded joint. Example

At least two flame heads 26 are arranged at the bottom end of the stabilizing tube 25 at equal distances. A connecting pipe 33 is installed at the top end of the mounting plate 24. The connecting pipe 33 pushes the fuel into the inside of the stabilizing tube 25. The welding end of the plug-in partition body 15 is preheated by the flame heads 26. At least two flame heads 26 are fixedly installed at the bottom end of each stabilizing tube 25. A fixing platform 16 is fixedly installed at the top end of the base 11. The plug-in partition body 15 is arranged at the top end of the fixing platform 16.

[0025] A flame baffle 27 is fixedly installed on the surface of each stabilizing tube 25, a pull rod 28 is rotatably installed at the end of each stabilizing tube 25, a threaded rod 32 is rotatably installed on the top of the mounting plate 24, an adjusting plate 31 is sleeved on the surface of the threaded rod 32, the top ends of the two pull rods 28 are rotatably connected to the outer sides of the adjusting plates 31, and two mounting sleeves 29 are fixedly installed on the side ends of each mounting plate 24. The rotating threaded rod 32 pulls the adjusting plate 31 to move upward, and at the same time, the side end of the adjusting plate 31 is rotatably connected to the top end of the pull rod 28, and the end of the adjusting plate 31 is rotatably connected to the end of the stabilizing tube 25. The movement of the adjusting plate 31 pulls the pull rod 28 is deflected, and at the same time, the end of the pull rod 28 generates a thrust on the stabilizing tube 25, so that the stabilizing tube 25 rotates inside the mounting sleeve 29, and the spray angles of multiple flame heads 26 are adjusted. A hydraulic rod 19 is fixedly installed on the top of the first support frame 14, and two connecting pipes 33 are fixedly installed on the top of the mounting plate 24. A guide frame 12 is fixedly installed on the top of the base 11, and a driving rod 13 is rotatably installed inside the guide frame 12.

At least two guide rods 18 are fixedly installed on the bottom end of the second support frame 21.

[0026] Working principle:

[0027] In the first step, a motor and a control system are provided inside the base 11, and the partition body 15 is placed on the top of the fixed platform 16, and the side ends of the fixed platform 16 are provided with clamping plates 17 on two sliding plates of the fixed platform 16, and the clamping plates 17 are pulled to squeeze and fix the side ends of the partition body 15 through the two clamping plates 17, and at the same time, one end of the fixed platform 16 is aligned with the bottom end of the welding module 22, and the driving rod 13 is rotated to rotate inside the guide frame 12, and the surface of the driving rod 13 is provided with a thread, and the driving rod 13 is driven. The moving rod 13 passes through the end of the first support frame 14, allowing the first support frame 14 to slide horizontally inside the guide frame 12. At the same time, a hydraulic rod 19 is installed at the top end of the first support frame 14, and a plurality of guide rods 18 are installed at the bottom end of the second support frame 21 to allow the second support frame 21 to move stably. The hydraulic rod 19 is driven to extend and retract, pushing the second support frame 21 to move at the top end of the first support frame 14, adjusting the position of the welding module 22 so that the welding module 22 is close to the side end of the partition body 15, and welding one end of the partition body 15 is performed.

[0028] In the second step, before welding, two stabilizing tubes 25 are installed at the side ends of the welding module 22, and at least two flame heads 26 are arranged at the bottom ends of the stabilizing tubes 25. The multiple flame heads 26 are equidistantly arranged at the bottom ends of the stabilizing tubes 25. A connecting tube 33 is installed at the top end of the mounting plate 24.

The splashing flame heats the welding end. The preheating can increase the overall temperature of the plug-in partition body 15 before welding, reduce the temperature difference during welding, and thus reduce thermal stress. Reducing thermal stress can effectively reduce welding deformation. The appropriate preheating temperature can make the heat-affected zone in the welding process more uniform, reduce the formation of hard and brittle tissues, thereby improving the strength of the welded joint. At the same time, the preheating temperature of the stabilizing tube A flame baffle plate 27 is installed on the surface of 25, which intercepts the flame sprayed by the flame head 26 and protects the welding module 22. The threaded rod 32 is rotated to rotate on the top of the mounting plate 24. The surface of the threaded rod 32 is threadedly connected with the adjusting plate 31 by rotating the threaded rod 32.

At the same time, the side end of the adjusting plate 31 is rotationally connected to the top of the pull rod 28, and the end of the adjusting plate 31 is rotationally connected to the end of the stabilizing tube 25. The movement of the adjusting plate 31 pulls the pull rod 28 to deflect. At the same time, the end of the pull rod 28 generates a thrust on the stabilizing tube 25, allowing the stabilizing tube 25 to rotate inside the mounting sleeve 29, thereby adjusting the spray angles of multiple flame heads 26, facilitating rapid heating, and increasing flexibility of use.
