![]() Method of checking and controlling operation parameters of machine for continuous casting of metal
专利摘要:
L'invention concerne un procédé de contrôle et de régulation de paramètres de marche d'une machine de coulée continue de bandes entre cylindres. Ce procédé consiste à considérer comme paramètres le couple exercé sur l'un au moins des cylindres pour faire avancer la bande et/ou l'effort exercé par la bande sur l'un au moins des tourillons et/ou la température de la bande à la sortie des cylindres et à mesurer en permanence l'écart entre la valeur instantanée d'un de ces paramètres et la valeur moyenne de ce paramètre durant une période de temps immédiatement antérieure. Lorsque cet écart dépasse un écart de référence, la vitesse de coulée de la machine est réduite jusqu'à ce que l'écart redevienne inférieur à l'écart de référence. Puis, la vitesse de la machine de coulée est augmentée tant que cet écart reste inférieur à t'écart de référence. Ce procédé trouve son application dans la coulée continue des métaux entre cylindres dans tous les cas où on veut optimaliser les conditions d'obtention d'un produit de qualité, et, notamment, d'augmenter la productivité. 公开号:SU1215608A3 申请号:SU813323299 申请日:1981-08-31 公开日:1986-02-28 发明作者:Берковиси Серж 申请人:Скаль Сосьете Де Кондисьоннеман Ан Алюминьюм (Фирма); IPC主号:
专利说明:
f 12 The method relates to metallurgy, in particular to the control of a continuous metal casting machine. The aim of the invention is to increase machine productivity and increase product quality The drawing shows a device that implements the method. It contains a pouring nozzle 1 through which the liquid metal is directed into the gap between the cylinders 2, pins 3 and 4 of which are supported: with pillows 5 and 6, which are integral with the bed 7. After cooling and rolling, the metal leaves the mass in the form of a strip 8, which is wound into a roll 9. The rolls are driven in rotation by an electric motor 10. The device also contains an 11 torque meter for an electric motor, hydraulic clamping devices 12 gauges 13 rolling force, a pyrometer 14 measuring the average strip-width temperature, a computing unit 15e control unit 16 S The device works as follows. In the computational unit, using the measured values of the motor torque, rolling force and strip temperatures, calculate the average values of these parameters for a time period preceding this moment, calculate the deviation of the parameter measured at a given moment from its average value for the preceding period of time. The decrease in the torque of the motor measured at a given time and the rolling force from the average values are a consequence of the occurrence of such defects as tears, leakage of metal into the connector of the mold, etc. At the same time, a defect in metal casting is indicated by the excess of the instantaneous value of the temperature of its average value over the preceding period. In the future, the absolute deviation is compared in the computing unit VNIIPI Order 914/62 Circulation 757 Subscription Branch PPP Patent;, Uzhgorod, ul, Proektna, 4 8 Some parameters from a given value of Kj if the absolute deviation is less than a specified value, the casting speed remains at the same level, if the absolute deviation of the parameter is greater than a specified value, the casting speed is reduced, The reduction in speed can be carried out continuously or in steps of a certain length and can continue until the deviation is lower than the specified value. The specified deviation value is usually lower than 10% of the average value for TorOj to take into account the time the machine performs the task , In the case when the speed reduction is carried out in successive stages 5, each stage lasts less than 5 minutes and the speed decreases by The caldamal stage is less than 15% of the speed value at the previous stage. After reducing the speed, the deviation of the parameters becomes lower than the specified one. At this point, the computing unit generates a signal to increase the speed by 10% or less. Compared with the value of speed tee at the previous moment and the pro. compares the deviation between the instantaneous value of the parameter and its average value for 5 minutes, The speed increase can be carried out continuously or in steps. In the latter case, the speed increase at each step is less than 10% of the speed value in immediately preceding but ™ ment 5, with a step duration of up to 5 minutes. The sweep continues until 5 as long as the deviation does not exceed the specified value T; S, a continuous metal casting machine will always work without. defects at maximum speed p performance
