Wide-section dummy bar and guiding device thereof

Abstract

The invention relates to a wide-section dummy bar and a guiding device thereof, and belongs to the technical field of metallurgical machinery. A first double-diameter side guiding roll is arranged ona supporting roll, a second double-diameter side guiding roll is arranged on a lower supporting roll, the first double-diameter side guiding roll and the second double-diameter side guiding roll are double-diameter guiding wheels and each comprise a small guiding wheel and a large guiding wheel, each large guiding wheel is arranged on the upper portion of the corresponding small guiding wheel, andthe diameter of each large guiding wheel is larger than that of the corresponding small guiding wheel. According to the wide-section dummy bar and the guiding device thereof, the wide-section dummy bar can always have two points to be accurately guided in the running process through the two groups of double-diameter side guiding wheels.

Description

technical field [0001] The invention relates to a dummy rod in steelmaking continuous casting equipment and a guide device for storing the dummy rod, which is suitable for billets of various continuous casting steel types and belongs to the technical field of metallurgical machinery. Background technique [0002] The dummy bar and the dummy bar storage device in the continuous casting machine are the key equipment of the continuous casting machine. Its main function is: before pouring, the dummy bar storage device will move the dummy bar from above the casting line to the casting line, and the dummy bar will go up along the predetermined track formed by the guide section under the thrust of the tension leveling machine , accurately enter the lower mouth of the crystallizer; during casting, the molten steel solidifies and connects with the dummy rod head in the mold; Going down along the predetermined trajectory formed by the guide section, the drawing and straightening mach...

Problems solved by technology

[0009] like Figure 5 As shown, when the part of the dummy bar shaft 101 with the side guide plate 102 is away from the upper idler 103, the gap between the rim of the idler 103 and the dummy bar shaft 101 is very large, and it is impossible to ensure that the dummy bar shaft 101 does not deviate

[0010] like Image 6 As shown, when the part of the dummy bar body 101 with the side guide plate 102 is away from the lower side guide roller 105, the gap between the opening of the side guide roller 105 and the dummy bar body 101 is very large, and it is impossible to ensure that the dummy bar body 101 don't go off track;

[0011] With the side guide method of the existing dummy rod storage device, the dummy rod often deviates irregularly from left to right during operation, and even twists and moves forward, which often leads to the inability of the dummy rod to enter the crystallization accurately before pouring. The lower opening of the device cannot be accurately entered into the dummy bar storage device after pouring, which directly affects the normal production of the user
