Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling, in particular to a hot rolling guide ruler device. Background Technique

[0002] The front guide ruler is arranged in front of the main rolling mill and above the front combined roller table, and is an essential device on the hot rolling mill. When the ingot is conveyed to the position of the front guide ruler, the guide ruler quickly clamps the ingot for centering, so that the center line of the ingot coincides with the rolling center line. The ingot is sent into the rolling rolls by the roller table. During the rolling process, the guide ruler also has functions such as generating rear tension and preventing the strip from running off. Whether the structural design of the guide ruler is reasonable has a significant impact on improving product quality and yield. The guide ruler is driven by a hydraulic cylinder, and guide devices are arranged on both sides of the cylinder to prevent the guide ruler from skewing or swinging due to uneven force during operation. The two guide columns are connected by a connecting beam to increase the stability of the front guide ruler device.

[0003] At present, the contact surface between the guide ruler and the strip is a whole steel plate, and the friction between the guide ruler and the strip is large, resulting in a large impact force on the guide ruler during the movement of the strip, which easily wears the contact surface between the guide ruler and the strip, thus damaging the guide ruler. Therefore, it is necessary to frequently stop the machine for replacement, which reduces the work efficiency and is inconvenient to use. Content of the Utility Model
