Description
ФОТОЭЛЕКТРОННЫЙ СПОСОБ ИЗМЕРЕНИЯ ТОЛЩИНЫ PHOTOELECTRONIC METHOD OF MEASUREMENT THICKNESS
(54) ГОРЯЧЕГО И ХОЛОДНОГО ПРОКАТА(54) HOT AND COLD RENTAL
: Известны фотоэлектронные способы иэ- мерени толщины гор чего и холодного проката , при которых измерение толщины осуществл ют по импульсным световым парап дельным штрихам, создаваемым на противоположных поверхност х проката с помощью импульсных осветителей.: Photoelectronic methods are known for measuring the thickness of hot and cold rolled products, in which the thickness measurement is carried out using pulsed light strips created on opposite rolled surfaces with the aid of pulsed illuminators.
Однако такие способы не позвол ют производить измерение толщины гор чего и холодного проката с необходимой точносгью при повыщенных скорост х перемеш&ВИЯ проката.However, such methods do not allow measurement of the thickness of hot and cold rolled products with the required accuracy at elevated rates of mixed and rolled products.
С целью повыщени точности измерени при повыщенньтх скорост х перемещени проката световые штрихи проецируют в одну плоскость таким образом, чтобы раосто ние между ними было пропорционально толщине проката, запоминают их изображе. ние с помощью электронно-оптического запоминающего элемента, преобразуют раосто ние между штрихами в видеосигнал, а затем - в показани прибора любым изь&стным способом.In order to increase the measurement accuracy at higher rolling speeds, the light strokes are projected into one plane so that the distance between them is proportional to the thickness of the rolled metal and their image is remembered. using an electro-optical storage element, convert the distance between the strokes into a video signal, and then into the readings of the instrument in any way.
|на фиг. 2 - мишень электронно-оптическо го запоминающего элемента со световыми штрихами.in fig. 2 - the target of the electron-optical storage element with light strokes.
Устройство содержит установленные под противоположными поверхност ми А и Б проката 1 импульсные осветители 2 и 3, оптическую систему, включаюихую объективы 4, 5 и 6 и зеркала 7, 8, и 9, электронно-оптический запоминающий элемент 110 с мишенью 11 и блок 12 электронной обработки и индикации. С покгощью осветителей на противоположных поверхност х А и Б проката 1 образуют параллельные импульсные световые штрихи Qt и (У . Отра женные штрихи с; и О при помощи объектива 4 и 5, зеркал 9 и 7, зеркала 8, |объектива 6 соответственно проецируют I на мишень 11 элемента 1О таким обра зом , что рассто ние между спроецирован;ными на мишень штрихами о и 2 пропорционально рассто нию между штрихами iCL к 5 аа поверхности А и Б проката, 1то есть толщине cL проката. 1 Электронно-оптический запоминающий элемент с помощью блока 12 электроннойThe device contains impulse illuminators 2 and 3 installed under opposite surfaces A and B of rolled products 1, an optical system, including lenses 4, 5 and 6 and mirrors 7, 8, and 9, an electron-optical storage element 110 with a target 11 and a block 12 electronic processing and display. With illuminators on opposite surfaces A and B of rolled 1, parallel pulsed light strokes Qt and form a (D. Reflected strokes c; and O with lens 4 and 5, mirrors 9 and 7, mirrors 8, | lens 6, respectively, projecting I on the target 11 of the element 1O in such a way that the distance between the strokes o and 2 projected onto the target is proportional to the distance between the iCL strokes to 5 aa of rolled surface A and B, this is the rolled thickness cL. using block 12 electronic
