Air bag type roller gap measuring device and measuring method

Abstract

The invention provides an air bag type roller gap measuring device and a measuring method. The air bag type roller gap measuring device is used for measuring the values of roller gaps between upper pinch rollers and lower pinch rollers. The air bag type roller gap measuring device comprises a frame, air bag type supporting units, measuring units and a processing unit. The air bag type supporting units and the measuring units are arranged on the frame. When the measuring units pass through the pinch rollers of a fan-shaped section, the air bag type supporting units simulate the bulging force of a casting blank to eject the fan-shaped section open, the measuring units detect roller gap data of the fan-shaped section and transmit the roller gap data to the processing unit, and the processing unit conducts data processing on the roller gap data to obtain the values of the roller gaps between the upper pinch rollers and the lower pinch rollers in a roller row. The roller gap values measured by the device are closer to the real state of a continuous casting machine in the production process, the obtained data are used for guiding the precision control of the continuous casting machine, the important supporting effect on smooth production of the slab continuous casting machine and guaranteeing of the casting blank quality is achieved, the downtime, caused by calibration and the like, of the casting machine can be shortened advantageously, and the operation rate of the casting machine is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic detection of metallurgical continuous casting machines, in particular to a balloon-type roll gap measuring device and a measuring method. Background technique [0002] In the production process of the continuous casting machine, the roll gap is a key equipment parameter to ensure the normal solidification and formation quality of the continuous casting slab and to guide the slab through the sector, etc., and has a decisive impact on the internal quality of the continuous casting slab. At present, various enterprises use roll gap measuring instruments to support the pinch rollers to eliminate the gap through springs and other devices. Because the spring force is not large enough, the gap between the pinch roll and the bearing can be eliminated, but there is no way to eliminate the gap between the upper and lower frames. , it cannot really measure the real roll gap condition of the continuous cast...
