(54) СПОСОБ КОНТРОЛЯ ТОЛЩИНЫ ВЫТЯГИВАЕМОЙ В ВАЛКАХ ЛЕНТЫ СТЕКЛА(54) METHOD FOR CONTROLLING THE THICKNESS OF THE GLASS TAPE EXTRACTABLE IN THE ROLLS
1one
Изобретение относитс к измери .тельной технике и может быть использовано при производстве листового стекла и при прокате металла.The invention relates to a measuring technique and can be used in the production of sheet glass and in metal rolling.
Известен способ контрол толщины материала, заключающийс в том, что в материале возбуждают тепловой поток и по разнице температур до и после нагрева материала суд т о его толщине 1 .There is a method of controlling the thickness of a material, which consists in that a heat flux is excited in a material and, judging from the temperature difference, before and after heating the material, it is judged on its thickness 1.
Недостатком известного устройств вл етс невысока достоверность контрол , так как разность температуры зависит от стабильности потока тепла.A disadvantage of the known devices is the low reliability of the control, since the temperature difference depends on the stability of the heat flow.
Наиболее близким к изобретению вл етс способ контрол толщины выт гиваемой в валках ленты стекла, заключающийс в TJOM, что измер ют температуру поверхности ленты 2,Closest to the invention is a method of controlling the thickness of the extruded glass ribbon in rolls, which consists in TJOM, which measures the surface temperature of the ribbon 2,
Недостаток известного способа состоит в невысокой точности измерени , так как он не дает информацию об отклонени х толщины ленты стекла, вызванных нарушением технологического режима гThe disadvantage of this method is the low accuracy of measurement, since it does not give information about the deviations of the thickness of the glass ribbon caused by the violation of the technological regime g
Цель изобретени - повьшение точности контрол .The purpose of the invention is to increase the accuracy of the control.
Поставленна цель достигаетс тем, что определ ют изменениеThe goal is achieved by determining the change
температуры по длине ленты стекла: после валков и по нему суд т об изменении толщины ленты.temperature along the length of the glass ribbon: after the rolls and it is judged to change the thickness of the tape.
Кроме того, поле измерени выбирают меньшим половины окружности валка, In addition, the measurement field is chosen to be less than half the roll circumference,
Известно, что слои стекла с различной толщиной имеют различную теплоемкость и, следовательно, разo личную температуру поверхности, Измер температуру поверхности ленты стекла,например, с помощью узкоугольного пир 1етра непосредственно за выт гивающими валками и It is known that layers of glass with different thicknesses have different heat capacities and, consequently, different surface temperatures. By measuring the surface temperature of a ribbon of glass, for example, using a narrow angle pier directly behind the drawing rollers and
5 сравнива ее с колебани ми толщины ленты стекла, измеренными механическим способом, устанавливают эмпирическую зависимость между изменением толщины лента стекла и его 5 comparing it with the variations in the thickness of the glass ribbon measured mechanically, establish an empirical relationship between the change in the thickness of the ribbon of glass and its
0 температуры.0 temperature.
На чертеже показана блок-схема устройства, реализующего способ.The drawing shows a block diagram of a device implementing the method.
Устройство содержит узкоугольный радиационный пирс летр 1,,,например The device contains a narrow-angle radiation pier letr 1 ,,, for example
5 серии АПИР-С, валки 2 и индикаторный прибор 3. Пирометр 1 свизирован на ленту непосредственно за выт гивающими валками 2,APIR-S series 5, rollers 2 and indicator device 3. Pyrometer 1 is attached to the tape directly behind the pulling rollers 2,
Способ осуществл етс следующим The method is as follows.
0 образом. Измер емую ленту 4 стекла прот гивают через вгшки 2, пирометром 1 определ ют изменение температуры ленты 4 стекла по ее длине и по эти изменени м суд т о колебани х тол1ДИНЫ лентаг. Необходимым условием при измерении вл етс то, чтобы оптическое поле измерени пирометра было меньше половийы окружности валка. При отсутствии этого услови прибор из-за интегрировани темпера ры не зафиксирует периодические изменени ТОЛ11У1НЫ ленты стекла. Непрерывное измерение и управление .технологией выработки с целью изготовлени ленты с минимальными отклонени ми по толщине дают возмож ность значительно повысить коэффициент использовани стекломассы и улучшить технологические показатели производства.0 way. The measuring tape 4 of the glass is pulled through the lugs 2, the temperature of the tape 4 of the glass along its length is determined by the pyrometer 1, and judging from these changes only one oscillation is made. A necessary condition for the measurement is that the optical field of the pyrometer measurement is less than half the circumference of the roll. In the absence of this condition, the device, due to the integration of the temperature, will not fix periodic changes in the TOL1111NY glass tape. Continuous measurement and control of production technology for the manufacture of a tape with minimal deviations in thickness make it possible to significantly increase the utilization rate of the glass mass and improve the technological performance of production.
