Technical Field
[0001] The utility model relates to the technical field of steelmaking, in particular to a novel device for preventing steel from piling up at the tail of a bar. Background Art
[0002] The characteristics of the bar production line are multi-stage units and multi-stage water penetration. The development direction is low-temperature rolling throughout the entire process, so as to obtain better organizational performance parameters. Therefore, there are usually multiple units, such as roughing and intermediate rolling units, pre-finishing rolling units, and finishing rolling units. Some high-bar production lines even have multiple finishing rolling units, such as finishing rolling unit one and finishing rolling unit two.
[0003] The tension control device on the rolling line is a looper. After the front and rear stands are engaged, the looper starts to lift the looper and adjusts the rolling speed of the front and rear rolling mills according to the looper height, thus ensuring that the red steel is always in a stable tension state. However, due to the rollers and water-piercing equipment between the units, and the very long distance between the front and rear rolling mills across the unit, ranging from about 30 to 70 meters, after the rear rolling mill is disengaged, the middle looper loses its original function due to lack of tension, causing the rear 30 to 70 meters of red steel to be in a free rolling state. This will cause this section of red steel to be in a pile state, and the material shape of this section is very likely to exceed the standard. Therefore, how to solve the problem of stabilizing the tension of this section of red steel has become a difficult problem that needs to be solved urgently. Summary of the Invention
