Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting processing, in particular to a continuous casting secondary cooling spray device. Background Art

[0002] Continuous casting is the abbreviation of continuous steel casting. In the process of producing various steel products in steel plants, there are two methods of using molten steel to solidify and shape: traditional mold casting and continuous steel casting. The continuous casting technology that appeared in Europe and the United States in the 1950s is an advanced technology that directly casts molten steel into shape. Compared with traditional methods, continuous casting technology has significant advantages such as greatly improving metal recovery rate and billet quality, saving energy, etc.

[0003] In the process of continuous casting technology, it is often necessary to cool the workpiece. A common method is to use a sprayer to spray coolant on the workpiece several times, so as to achieve the purpose of high-quality and high-yield solidified continuous casting billets. Most of the existing continuous casting secondary cooling spray devices place the workpiece on a platform and spray coolant on it. This will cause some surfaces of the workpiece to be unable to be fully sprayed with coolant, and then the staff needs to stop spraying and adjust the placement of the workpiece, which affects the work efficiency and increases the labor intensity of the staff.

[0004] Therefore, we propose a continuous casting secondary cooling spray device to solve the above problems. Utility Model Content

The bevel gear 16 and the bevel gear 2 18 are meshed, so that the working motor 17 can drive the reciprocating screw 12 to rotate through the gear transmission when working;

[0025] A water vapor absorption component is also provided on the work frame, and the water vapor absorption component includes a work plate fixedly connected to the side wall of the work frame, and an air duct 19 is penetrated through the work plate, and the work plate provides a working position for the air duct 19 to prevent the air duct 19 from falling off, and a limiting ring is fixedly connected inside the air duct 19, and a working rotating rod 20 is rotatably connected to the limiting ring, and the end of the working rotating rod 20 close to the reciprocating screw 12 is fixedly connected to a bevel gear three 21, and the bevel gear three 21 and the bevel gear one 16 are meshed, so that when the reciprocating screw 12 rotates, the working rotating rod 20 can be driven to rotate through gear transmission, and the end of the working rotating rod 20 away from the bevel gear three 21 is fixedly connected to a rotating fan blade 22, and the rotating fan blade 22 can form an air suction effect when it rotates, thereby sucking away the water vapor generated during the cooling process, making it convenient for the staff to clearly check the cooling situation.

[0026] When the workpiece is in use, the staff first places the workpiece on the fixing frame 8 with a tool, and then rotates the small screw rod 9. Due to the characteristics of the threaded connection, the fixing plate 10 will slide downward along the small screw rod 9 under the limiting action of the fixing frame 8, thereby fixing the two sides of the workpiece to achieve the clamping work of the workpiece, and then start the electric telescopic rod 15, so that the sprayer 2 fixedly connected to the output end of the electric telescopic rod 15 moves downward. When the nozzle of the sprayer 2 enters the cooling box 3, the staff can close the electric telescopic rod 15, and then start the working motor 17 and the sprayer 2, so that the auxiliary shaft fixedly connected to the output end of the working motor 17 rotates, thereby driving the bevel gear 2 18 to rotate. Due to the characteristics of gear meshing, the bevel gear 1 16 will also start to rotate, thereby driving the reciprocating screw 12 to rotate. At this time, the working slide block 14 will slide left and right along the reciprocating screw 12 under the limiting action of the working slide bar 13, thereby causing the sprayer 2 to move left and right, thereby constantly changing the spraying position, greatly improving the spray cooling effect;

[0027] At the same time, the rotation of the reciprocating screw 12 will also drive the bevel gear three 21 to rotate through the gear transmission, thereby causing the working rotating rod 20 to rotate, thereby causing the rotating fan blades 22 to rotate, thus forming an air suction effect, which can absorb a large amount of water vapor generated during the cooling process, making it convenient for the staff to observe the cooling situation. Then the staff only needs to rotate the working shaft 7 as needed to adjust the workpiece, so that the coolant can be fully sprayed on it. Finally, the staff only needs to release the fixing effect of the fixing plate 10 on the workpiece, take out the workpiece and place it in the finished product collection frame for storage, and then centrally process the coolant in the coolant collection box 6.
