3results about How to "Improve rolling stability" patented technology

The utility model provides a rolling and packaging mechanism and a pillow packaging line. The rolling and packaging mechanism comprises a switching assembly, a rolling limiting assembly, a pushing assembly and a rolling assembly. A first rolling limiting cavity and a second rolling limiting cavity are formed in the rolling limiting assembly, the switching assembly is in driving connection with the rolling limiting assembly, the rolling limiting assembly can be switched to a first posture and a second posture under driving of the switching assembly, and the rolling assembly is used for rolling a workpiece in the first rolling limiting cavity or the second rolling limiting cavity. The pushing assembly is used for pushing out the workpieces in the first rolling limiting cavity or the second rolling limiting cavity. Compared with the prior art, the rolling and packaging mechanism can conduct rolling operation and anti-explosion bag sleeving operation at the same time, the production takt is accelerated, and the production efficiency is improved; and the rolling stability can be improved through the two rolling assemblies.

The application discloses a method and system for judging feedback thickness difference abnormality and roll gap processing in a hot rolling process, which comprises the following steps: setting an interval range and an abnormality frequency upper limit; after the strip steel is completed, real-time instrument feedback thickness difference is obtained, whether the instrument feedback thickness difference exceeds the interval range is judged, and the frequency of the real-time instrument feedback thickness difference exceeding the interval range is recorded; when the frequency of the recorded instrument feedback thickness difference exceeding the interval range exceeds the abnormality frequency upper limit, it is determined that the instrument feedback thickness difference abnormality occurs at this time; at this time, the roll gap target value is corrected correspondingly. The application is beneficial to solve the problems of abnormal equipment operation caused by the set abnormality, strip steel rolling and the serious thickness difference detection distortion caused by the serious strip steel wave caused by the abnormality of the instrument detection thickness difference feedback in the rolling process, and has a positive significance for improving the rolling stability.
