Abstract
Description
Technical Field
[0001] The utility model relates to the field of hot rolling mills, and more specifically, to a hot rolling mill guiding device. Background Art
[0002] Hot rolling is an indispensable step in the production and processing of steel. Usually, a guide device needs to be set before the horizontal rolling mill to guide the steel to be hot rolled into the hot rolling mill. The guide devices currently used are mostly welded from a rectangular guide frame. During use, when the rolled piece enters the rolling mill, it often rubs against the guide plate near the discharge port of the guide frame before it bites into the rolling mill. Long-term work will cause the guide plate of the guide frame to wear, or the tension of the material changes during rolling, causing the tension of the rolled piece to slide freely and rub against the guide plate, causing the guide plate to wear. If the guide plate is not replaced after being worn, the strip head will often bend, which is difficult to adjust and can easily cause steel piling.
[0003] Therefore, a hot rolling mill guide device is proposed to solve the above problems. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a hot rolling mill guide device, which solves the problems raised in the above-mentioned background technology by arranging guide pads that are easy to replace on the upper and lower guide plates, arranging parts that are easier to replace, and arranging guide wheels at the ends of the left and right guide plates to change sliding friction into rolling friction.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hot rolling mill guide device, comprising: a guide frame, the guide frame comprising a symmetrically arranged left guide plate and a right guide plate, symmetrically arranged upper guide plates and lower guide plates located at the discharge ends of the left guide plate and the right guide plate, respectively fixed with guide wheels vertically arranged on a rotating shaft; a guide pad, the guide pad is detachably fixedly connected to the inner walls of the upper guide plate and the lower guide plate; wherein the guide surface of the guide pad is higher than the inner wall surfaces of the upper guide plate and the lower guide plate, and the feed end of the guide pad is provided with a guide slope surface.
[0006] Furthermore, grooves are provided on the guide surfaces of the upper guide plate and the lower guide plate, and the guide pad is fixedly connected to the grooves from the back by bolts.
