Description
(54) УСТРОЙСТВО ДЛЯ АВТСМАТИЧЕСКОГО ЗАПУСКА И РЕГУЛИРОВАНИЯ УРОВНЯ ЖИДКОГО МЕТАЛЛА В КРИСТАЛЛИЗАТОРЕ МАШИНЫ НЕПРЕРЫВНОГО (54) DEVICE FOR AVSMATIC LAUNCH AND REGULATION OF THE LEVEL OF LIQUID METAL IN A CRYSTALIZER OF A CONTINUOUS MACHINE

Устройство относитс к черной металлургии, а точнее - к- машинам непрерывного лить стали (МНЛС), работающих самосто тельно или в общей линии с прокатньм станом и другими механизмами, св занных непрервашным слитком.The device relates to ferrous metallurgy, or more precisely, to continuous casting machines (MNLS), working independently or in a common line with a rolling mill and other mechanisms connected by an unbroken ingot.
Известно устройство регулировани уровн , которое содержит измеритель уровн жидкого металла,задатчик уров-0 н , регул тор уровн , релейный индикатор заданного уровн , электропривод т нуших валков или систему мно1годвигательного электропривода механизмов МНЛС - качани кристаллизатора, т ну-15 ших валков и перемещени затравки, на которые помимо общего сигнала задани скорости воздействует сигнал с выхода регул тора уровн жидкого металла 1.20A level control device is known which contains a liquid metal level meter, a level gauge-0 n, a level regulator, a relay indicator of a given level, electric drives of the best rolls or a multivariable electric drive system of the caster mechanisms of the crystallizer, t-15 rolled rolls and displacements , which, in addition to the general speed reference signal, are affected by the signal from the output of the liquid metal level regulator 1.20
Недостатки устройства состо т в том, что механизмам МНЛС скорость задаетс оператором с поста управлени и, как правило, к моменту автозапуска не соответствует скорости 25 поступлени струи жидкого металла в кристаллизатор, что приводит к излишней колебательности системы регулировани при выравнивании скоростей поступлени струи жидкого металла в 30 ЛИТЬЯ СТАЛИтThe drawbacks of the device are that the speed adjustment mechanisms are set by the operator from the control station and, as a rule, by the time of autorun, the speed 25 does not correspond to the flow of liquid metal into the mold, which leads to excessive oscillation of the control system when the flow rates of liquid metal in 30 CAST STEEL
кристаллизатор и выт гивани слитка и установлени заданного уровн жидкого металла в кристаллизаторе. При наличии в устройстве интегральной части регул тора уровн разница скоростей выт гивани слитка и поступлени струи жидкого металла в кристаллизатор , вызванна различными причинами (например, из-за ошибки оператора в выборе скорости, изменени уровн жидкого мета.пла в промежуточной емкости и др.), устран етс за счет интегральной части регул тора уровн , однако, после прекращени подачи струи жидкого металла в кристаллизатор вход регул тора уровн отключаетс и тогда возможно изменение выходного сигнала регул тора из-за дрейфа нул его усилител .mold and ingot extrusion and setting a predetermined level of liquid metal in the mold. If the device has an integral part of the level regulator, the difference in the speeds of ingot extrusion and the flow of liquid metal into the mold caused by various reasons (for example, due to operator's error in choosing the speed, changing the level of the liquid metapl in the intermediate tank, etc.) , is eliminated due to the integral part of the level regulator, however, after stopping the supply of a jet of liquid metal to the mold, the input of the level regulator is turned off and then the output signal of the regulator may change due to drift and its amplifier zero.
Отмеченные недостатки отрицательно сказываютс на качестве непрерывного слитка .и вл ютс одной из причин прорывов жидкого металла.The deficiencies noted have a negative effect on the quality of the continuous ingot. And they are one of the reasons for the breakthroughs of the liquid metal.
Цель изобретени - улучшение качества регулировани уровн металла в кристаллизаторе и предотвращение прорывов.The purpose of the invention is to improve the quality of controlling the level of the metal in the mold and to prevent breakthroughs.
