Abstract
Раскрыт способ изготовления тонкой литой стальной ленты методом непрерывного литья. По крайней мере, два датчика в рабочем режиме соединены, по крайней мере, с одним концом, по крайней мере, одного из пары литейных прокатных валков или, по крайней мере, одной из пары щеток для непрерывного измерения, по крайней мере, двух связанных с силой вибрации параметров при литье. Генерируются, по крайней мере, два сигнала во временной области, соответствующие измеренным связанным с силой вибрации параметрам. Сигналы во временной области непрерывно контролируются и превращаются в соответствующие спектры в частотной области. Спектры в частотной области анализируются, и составляющие значения интенсивности непрерывно вычисляются из уровней интенсивности, п
