Abstract
Description
Technical Field
[0001] The utility model relates to a crystallizer positioning device for an ESP thin slab continuous casting machine, belonging to the technical field of slab continuous casting production equipment in the metallurgical industry. Background Art
[0002] The vibration unit and bending section of the ESP thin slab continuous casting machine are installed on the vibration foundation, and the crystallizer is fixed to the vibration unit frame by bolts. During the production process, due to the high vibration frequency of the crystallizer and the high water pressure of the strong cooling crystallizer, it is easy to cause the connection arc between the crystallizer foot roller and the bending section roller to shift. Every time the machine is stopped, the crystallizer cover must be opened for adjustment. It is necessary to ensure that the arc value of the crystallizer foot roller and the bending section roller is within 0.08 mm. If it is not adjusted, it is very easy to leak steel, which seriously affects the production rhythm and also increases the labor intensity of workers. Utility Model Content
[0003] The utility model aims to provide a crystallizer positioning device for an ESP thin slab continuous casting machine, which can avoid displacement of the crystallizer and solve the problems existing in the background technology.
[0004] The technical solution of the utility model is:
[0005] A crystallizer positioning device for an ESP thin slab continuous casting machine, wherein the crystallizer is fixed to a crystallizer vibration unit frame by bolts, and there are four sets of crystallizer positioning devices, which are symmetrically arranged on both sides of the crystallizer, and each set of crystallizer positioning devices comprises a base, a cotter pin, a pin shaft and a top screw, wherein the base is fixed to the crystallizer vibration unit frame by the pin shaft and the cotter pin, and a top screw matching the crystallizer is arranged on the base.
[0006] Furthermore, a top screw hole matching with the top screw is provided on the base, and the top screw passes through the top screw hole and is pressed tightly against the outer shell of the crystallizer.
[0007] Furthermore, there are two top screws on the base that match the crystallizer.
[0008] Furthermore, the base is provided with a pin shaft hole matched with the pin shaft, and the top screw hole and the pin shaft hole on the base are arranged vertically.

[0015] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0016] See attached Figure 1-4 A crystallizer positioning device for an ESP thin slab continuous casting machine, wherein a crystallizer 7 is fixed to a crystallizer vibration unit frame 9 by bolts 8. There are four sets of crystallizer positioning devices, which are symmetrically arranged on both sides of the crystallizer. Each set of crystallizer positioning devices comprises a base 2, a cotter pin 3, a pin shaft 4 and a top screw 5. The base 2 is fixed to the crystallizer vibration unit frame 9 by the pin shaft 4 and the cotter pin 3. A top screw 5 matching the crystallizer 7 is provided on the base 2.
[0017] In this example, refer to the attached Figure 1-4 The central equipment of the ESP thin slab continuous casting machine is installed on the fan-shaped foundation of the continuous casting machine. The vibration unit and the bending section are installed on the vibration foundation, and the crystallizer is installed on the vibration unit frame, so that the crystallizer and the bending section are related to each other. Using the hoisting holes on the vibration unit frame on both sides of the crystallizer, four sets of adjustable crystallizer positioning devices are made and installed, as shown in the attached Figure 1-4 As shown, the top screws 5 in the four sets of crystallizer positioning devices are pressed against the crystallizer 7 to limit the crystallizer from deviating to the inner arc or outer arc. The specific installation steps are as follows:
[0018] (1) Fix the crystallizer 7 vertically on the crystallizer vibration unit frame 9 with bolts 8;
[0019] (2) The base 2 in the crystallizer positioning device is fixed to the lifting hole position of the crystallizer vibration frame 9 by the pin shaft 4 and the cotter pin 3, so as to achieve horizontal positioning;
[0020] (3) Tighten the two top screws 5 in the crystallizer positioning device against the bottom of the shell of the crystallizer 7 to prevent the crystallizer from shifting horizontally;
[0021] (4) Finally, the top screw 5 is locked with a lock nut to complete the horizontal reinforcement of the crystallizer 7.
[0022] After production trials, after each shutdown of the continuous casting machine, the arc connection accuracy of the crystallizer foot roller and the bending section roller was tested and there was no deviation or movement. Therefore, this mechanical positioning device perfectly solves the occurrence of the arc deviation between the crystallizer and the bending section.
