Description
Technical field
The present invention relates to thickness of strips detection field, more specifically, particularly relate to a kind of method utilizing steel band buffer unit on-line checking thickness of strips.
Background technology
Steel band refers to the conveyer belt that carbon steel is made, steel band both can build as the traction of belt conveyer and motion, can be used for bale cargo, to be all kinds of Metallurgical Enterprise be simultaneously adapts to different sectors-industrialization and produces a kind of narrow and long steel plate of each metalloid or engineering goods needs.Steel band also known as strip steel, general rolling supply, have dimensional accuracy height, surface quality good, just with processing and save the advantages such as material, steel band can Direct Rolling be the basic building of shelf simultaneously, is spliced into whole shelf again through bolt.
When utilizing the basic building of steel band rolling shelf, shelf factory typically directly obtains multireel steel band from steel band factory, the thickness of coiled steel differs, therefore two coil bands of same size are often because thickness its total length different is also different, often namely thickness of strips raising can make its length be greatly reduced a little, the method being typically with weighing due to the buying of steel band is valuated, if the thickness ratio of steel band is actually needed high, the coil of strip length that then same price has been bought then falls flat, result in the cost performance of purchase on the low side, therefore before producing, the thickness of steel band is carried out detection and seem particularly necessary.The steel band obtained from manufacturer is typically all nude pack, because the reason transported, load and unload and deposit, outer surface is not suitable as the sample of inspection, can only add measuring means in process of production, the thickness of steel band is tested；Simultaneously steel band itself deposit limitation, so as to cannot arbitrarily move, therefore, the coiled steel in a large amount of productions is being carried out Thickness sensitivity inconvenience very.
Meanwhile, after deployment, its surface is not flat state completely to coiled steel, and steel band is often in case of bending, and the thickness of the diverse location of unified coil band is often also not quite similar, and therefore detects also and is inconvenient to be made directly；Existing detection mode is manually to open coiled steel then to utilize micrometer to measure one by one, measure and not only waste time and energy, expend substantial amounts of manpower and materials, anthropic factor simultaneously is also the great factor affecting steel band accuracy of measurement, measure workman and be likely to not complete measument thickness of strips, and deal with the Thickness sensitivity task of steel band only according to getting sth into one's head of oneself, this brings strong influence to the accuracy of thickness of strips detection.What thickness of strips detected simultaneously has suffered in process, the Thickness sensitivity data of steel band are always up manually being recorded, and not only easily make mistakes, and are also not easy to carry out the classified statistic of data, can not find the thickness data of corresponding coil of strip when needing, production is caused strong influence.
Existing steel band is when carrying out Thickness sensitivity, it is necessary to make the state that steel band remains stationary, and namely cannot be carried out measuring in the process of steel band processing.But the meaning of static its thickness measure of steel band is also little, in order to measure the same coil thickness with multiple positions, also tend to need manually to pull open steel band, so not only bad for measurement, and operate excessively loaded down with trivial details, and the position measured also only is simply biased toward initial a section of coiled steel.In the process that steel band is processed, steel band is in continuous kinestate, if being capable of the on-line checking of thickness of strips in the process of steel band motion, the thickness situation of steel band diverse location can be understood in time to understand whether steel band meets the processing of next process at any time, thus bringing convenience to production.
