Problems solved by technology

[0003] Since the SONY magnetic scale is installed on the HGC cylinder at the bottom of the rolling mill, the working conditions on site are relatively harsh, such as oil pollution, cooling water, high temperature and strong vibration, etc. These unfavorable factors seriously threaten the safe operation of the SONY magnetic scale.
Despite regular dismantling inspections and strict protection, SONY magnetic scale failures still occur occasionally during the production process
Due to the strict requirements of the site environment and precision instruments, it often takes a long time to deal with SONY magnetic scale faults, resulting in a long shutdown of the rolling mill, which affects the normal production rhythm

Embodiment Construction

[0018] figure 1 , 2 As a specific embodiment of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0019] The equipment part of the method for online redundancy of the SONY magnetic ruler of a rolling mill comprises: a SONY magnetic ruler, a SONY magnetic ruler signal receiver, and a special cable for the SONY magnetic ruler.

[0020] Implementation example:

[0021] 1. Prepare the equipment and materials required by the present invention, and simultaneously select the installation position of the redundant SONY magnetic ruler.

[0022] 2. Install 2 SONY magnetic rulers on the diagonal as redundancy on each HGC cylinder, and take the average value as the actual position of the HGC cylinder.

[0023] 3. Using the original TDC control system, its installation location is in the TDC automation control cabinet in the 3# electrical room. Add a SONY magnetic ruler signal processor in the TDC automation con...

Abstract

A rolling mill SONY magneto-scale online redundancy method belongs to the technical field of heavy and medium plate rolling mills. Aiming at sensitivity of a rolling mill roll gap adjusting system for signal adjusting stability, two SONY magneto-scales are newly added in a diagonal mode, signal collection is carried out by aid of four sensors with the same work principle in advantage complementation and combination mode, and the average value of the four sensors is taken from the system to serve as an actual position of a hydraulic gap control (HGC) cylinder. In the production process, if one sensor breaks down, the system can switch to the other group of sensors to continue production, accordingly stability of the milling roll adjusting system is enhanced, fault processing time can be shortened to the maximum limit, and smooth operation of production is ensured.

Description

technical field [0001] The invention belongs to the technical field of medium and heavy plate rolling mills, and in particular provides a method for online redundancy of SONY (Sony) magnetic rulers of rolling mills, which realizes online redundancy of SONY magnetic rulers of rolling mills in a fully automatic steel rolling mode. Background technique [0002] The HGC cylinder is the core equipment of the rolling mill. Its position detection adopts the precision instrument SONY magnetic scale position sensor produced by Japan's SONY company. Its stable operation is an important guarantee to ensure the normal production of the rolling mill. Therefore, SONY magnetic tape is also a key item in daily maintenance and routine repair. [0003] Since the SONY magnetic scale is installed on the HGC cylinder at the bottom of the rolling mill, the working conditions on site are relatively harsh, such as oil pollution, cooling water, high temperature and strong vibration, etc. These unfav...
