Изобретение относитс к обработке металлов давлением и может быть использовано дл замера момента прокатки при исследовании процесса прокатки в лабораторных услови х.The invention relates to the processing of metals by pressure and can be used to measure the rolling moment in the study of the rolling process in laboratory conditions.
Известные устройства дл замера момента прокатки регистрируют крут щий момент М складьшающийс из момента прокатки Мд и момента трени в опорах валков Mj. Дл определени чистого момента прокатки необходимо вычесть из момента, замеренного на шпиндел х стана, момент трени в опорах валков;The known devices for measuring the moment of rolling register the torque M, the folding from the moment of rolling Md and the moment of friction in the roll supports Mj. To determine the net rolling moment, it is necessary to subtract from the time measured at the mill spindle, the moment of friction in the roll supports;
Мп , . Поскольку момент трени М мен ет значение в зависимости от давлени Р металла на валки , то дл определени момента прокатки необходимо знать значение М при давлении Р, соответствующем велишне замеренного момента М:Mp,. Since the friction moment M changes the value depending on the pressure P of the metal on the rolls, to determine the rolling moment, it is necessary to know the value M at pressure P corresponding to the measured moment M:
Mj J(PJ .(2)Mj J (PJ. (2)
Известен способ определени коэффициента трени , где дл определени момента прокатки и получени зависимости (2) необходимо демонтировать верхний валок стана 1. ТакThere is a known method for determining the friction coefficient, where for determining the rolling moment and obtaining the relation (2) it is necessary to dismantle the upper roller of the mill 1.
как валки прокатных станов имеют значительный вес, то их демонтаж и последующий монтаж сопр жены с определенными потер ми рабочего времени. Дл расчета момента прокатки , когда известны М и Р, вначале определ ют по зависимости (2), установленной заранее, момент трени в опорах, соответствующий значению Р, и только затем, определ ют по формуле (1) искомую величину. Однако услови .трени в опорах валков при определении зависимости могут отличатьс от условий трени при проведении экспериментов по замеру момента прокатки, что вносит погрещности в расчеты, св занные с определением чистого момента прокатки.As the mill rolls have a significant weight, their dismantling and subsequent assembly are coupled with a certain loss of working time. To calculate the rolling moment, when M and P are known, first determine according to relation (2), established in advance, the moment of friction in the supports, corresponding to the value of P, and only then, determine the desired value by formula (1). However, the conditions of the bearing in the roll supports when determining dependencies may differ from the conditions of friction when conducting experiments on measuring the rolling moment, which introduces inconsistencies in the calculations associated with the determination of the net rolling moment.
Известно также устройство дл замера моментов прокатки, включающее в себ прокатный валок с цапфами и месдозы 2.A device for measuring rolling moments is also known, which includes a roll with trunnions and mesdoses 2.
Недостатки известного устройства - невысока точность измерений и невозможность при его помощи получить, шстый момент прокатки .The disadvantages of the known device is the low accuracy of measurements and the impossibility with its help to get, the total moment of rolling.
Целью изобретени вл етс повыщение точности определени момента проката.The aim of the invention is to improve the accuracy of determining the moment of hire.
