Rolling mill rolling force detection structure

Abstract

The invention relates to a rolling mill rolling force detection structure. The rolling mill rolling force detection structure comprises a pressure equalizing plate, a pressure sensor, a compensation base plate and a roller replacing trolley, wherein the pressure equalizing plate, the pressure sensor and the compensation base plate are sequentially overlapped and fixed to form an integral pressuresensing unit, a through groove in the vertical direction is formed in the roller replacing trolley, the pressure sensing unit is arranged inside the through groove, the bottom of the pressure sensingunit is supported by rolling mill housing, and the periphery of the pressure sensing unit is limited by the roll replacing trolley and can move along with the roll replacing trolley. According to therolling mill rolling force detection structure, the mode that the rolling force transmission process depends on a rolling mill roll replacing mechanism and other measurement auxiliary systems is casted off, a layer-by-layer overlapped structure of the roll replacing system and other measurement auxiliary systems, machining precision accumulation deviation and abrasion among components on the rolling force detection accuracy are avoided, and the reliability and accuracy of rolling mill rolling force detection are improved.

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
