Rolling force detection structure of rolling mill

Abstract

The invention relates to a rolling force detection structure of a rolling mill, which comprises a pressure equalizing plate, a pressure sensor, a compensation backing plate and a roll changing trolley. There is a through slot along the vertical direction, the pressure sensing unit is set inside the slot and the bottom is supported by the rolling mill archway, the pressure sensing unit is limited by the roll changing trolley and can move with the roll changing trolley. The present invention gets rid of the dependence of the rolling force transmission process on the roll changing mechanism of the rolling mill and other auxiliary measurement systems, and avoids the layer-by-layer superposition structure of the roll changing system and other auxiliary measurement systems, the cumulative deviation of machining accuracy, and the wear and tear between parts on the accuracy of rolling force detection To improve the reliability and accuracy of the rolling force detection of the rolling mill.

Description

technical field [0001] The invention belongs to the technical field of rolling force detection of a rolling mill, and in particular relates to a rolling force detection structure of a rolling mill. Background technique [0002] Steel rolling mill is an important equipment for processing plates / strips. Plates / strips are high value-added steel products. The accuracy of steel products mainly refers to the accuracy of external dimensions. Accuracy indicators such as degrees. Among all the precision indicators, the flatness accuracy is one of the most important quality indicators to measure the sheet / strip, and it is an essential control method to calculate the flatness accuracy by using the measured value of the rolling force detection system. [0003] At present, the rolling force detection system adopted by the rolling mill usually adopts the pressure sensor products of George Keck Company of Canada or ABB Company of Sweden. The sensor is installed under the bearing seat of ...

Problems solved by technology

The wear of the wear plate will affect the measurement accuracy. The wear plate of the roll changing trolley is worn and needs to be replaced regularly, which requires a lot of maintenance.

[0008] The rolling force detection of the existing device, the rolling force transmission process, must be transmitted through the roll change mechanism of the lower back-up roll. system is about 220 tons), with the continuous replacement of support rolls during the use of the device, the wear of the roll change mechanism will increase, and the wear between the contact surfaces cannot be compensated, resulting in changes in the horizontality and elevation of the pressure sensor, resulting in the rolling force measurement the accuracy of
