Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical equipment, and further belongs to the technical field of steel rolling equipment, and specifically relates to a magnetic fixed adjustable centering instrument which is simple in structure, reliable in operation, and easy to operate and is suitable for centering adjustment of guides and guards. Background Art

[0002] The guide refers to the device installed before and after the slot of the roller ring (roller) to guide and support the rolled piece to enter the rolling mill smoothly and be rolled out during the rolling process of the steel section. The function of the guide device is to correctly guide the rolled piece into the slot of the roller ring (roller); to ensure that the rolled piece is stably deformed in the slot and obtains the required geometric shape and size; to smoothly guide the rolled piece out of the slot to prevent it from wrapping around the roller; to control or force the rolled piece to twist or bend and deform, and move in a certain direction. The alignment accuracy of the guide and the roller ring slot directly affects the quality of the product and the smooth progress of production.

[0003] In the steel rolling production, the finishing mill of the high-speed production line is relatively compact and the distance between the frames is small. After the inlet and outlet guides are installed, the gap between the frames and the guides is only about 120mm. The alignment of the guide and the roller ring slot cannot be directly observed with the naked eye. At present, most of them use the alignment of the guide base and the roller ring slot, or observe the alignment of the guide and the slot through a mirror. These two ways of checking the alignment have limitations. First, although the guide base is adjusted, each guide has different processing errors, wear, and installation pressures. It is often the case that the base is correct but the guide is not correct; second, there will be deviations in the viewing angle when observing with a mirror. The installation accuracy of the guide is high, especially the even-numbered frames have very high requirements for the alignment of the imported guide. The above-mentioned guide alignment adjustment method is not intuitive and cannot be quantified during inspection, which is easy to lead to misjudgment and production accidents. For this reason, the key to solving this problem is to research and develop a magnetic fixed adjustable alignment instrument suitable for guide alignment adjustment with simple structure, reliable operation, and easy operation.
