The invention provides a guide and guard cross beam for a rolling mill and a guide and guard centring method. The guide and guard cross beam comprises a cross beam body, connecting walls arranged at the left end and the right end of the cross beam body and a clamp claw arranged on the outer side of the front side wall of the cross beam body. The cross beam body is of a hollow cubic structure. A horizontal hole is formed in the front side wall of the cross beam body. An adjusting bolt passes through the horizontal hole to connect the cross beam body with the clamp claw. The clamp claw is used for fixing a guide and guard. Scales are set on the upper surface of the cross beam body. According to the guide and guard cross beam for the rolling mill and the guide and guard centring method, onlytwo vertical distances need to be measured, the method is simple and rapid, the problems about aribitrariness of direct manual visual inspection centring and the low speed are solved, and the guide and guard centring efficiency and accuracy are greatly improved.
Description
technical field [0001] The invention relates to the technical field of guide centering measurement, in particular to a guide beam for a rolling mill and a guide centering method. Background technique [0002] The guide is an indispensable workpiece on the short stress line rolling mill in steel rolling production, and plays a vital role in the accurate and stable deformation of the rolled piece through the bite of the roll. Short stress line rolling mills are divided into horizontal rolling mills and vertical rolling mills. The guides used in short stress line rolling mills are divided into inlet guides and outlet guides. The function is to assist the rolled piece to lead out of the roll smoothly without deviating from the rolling line. If the guide and guard deviate from the alignment, the following consequences will result: [0003] 1. It may cause defects such as indentation, scoring, and edge wrapping on the surface of the steel; [0004] 2. It may make it difficult t...
