Изобретение относится к металлургии и предназначено для использования при непрерывной разливке металлов. Устройство для контроля поверхностных дефектов горячей заготовки в процессе ее отливки на МНЛЗ содержит раму, датчик цилиндрической формы, ось которого перпендикулярна контролируемой поверхности, узел сканирования, включающий направляющие, параллельные контролируемой поверхности заготовки и перпендикулярные ее оси, установленную на направляющих с возможностью перемещения каретку с закрепленным на ней датчиком и привод перемещения каретки, и регистрирующую аппаратуру. Для повышения точности и быстродействия устройство дополнительно содержит вторую раму, второй датчик цилиндрической формы, ось которого перпендикулярна контролируемой поверхности, второй узел сканирования, включающий вторые направляющие, параллельные контролируемой поверхности заготовки и перпендикулярные ее оси, установленную на вторых направляющих с возможностью перемещения вторую каретку и второй привод перемещения второй каретки, оба узла сканирования дополнительно содержат соответственно первую и вторую тележки, установленные с возможностью касания колесами поверхности заготовки, причем первая и вторая тележки шарнирно закреплены на первой и второй рамах соответственно с возможностью поворота в двух взаимно перпендикулярных плоскостях, нормальных контролируемой поверхности, из которых одна параллельна оси заготовки, первая и вторая направляющие установлены на первой и второй тележке соответственно, второй датчик установлен на второй каретке, амплитуда сканирования

где Lз - ширина заготовки, R0 - радиус датчика, δ = 0-40 мм - ширина неконтролируемого участка вблизи кромки заготовки, а координаты центров датчиков вдоль оси, параллельной направляющим, в исходном положении X1=Ro+δ , X2 = Lз/2, где отсчет координат ведется от кромки заготовки.The invention relates to metallurgy and is intended for use in continuous casting of metals. A device for monitoring surface defects of a hot workpiece during its casting on a continuous casting machine comprises a frame, a cylindrical sensor, whose axis is perpendicular to the test surface, a scanning assembly including guides parallel to the test surface of the workpiece and perpendicular to its axes mounted on the guides movable with fixed on it is a sensor and a drive for moving the carriage, and recording equipment. To improve accuracy and speed, the device additionally contains a second frame, a second cylindrical sensor, the axis of which is perpendicular to the test surface, a second scanning unit that includes second guides parallel to the controlled surface of the workpiece and perpendicular to its axis, mounted on the second guideways to move the second carriage and the second the drive for moving the second carriage, both scanning units additionally contain, respectively, the first and second carriages with the possibility of the wheels touching the surface of the workpiece, the first and second carriages being hinged on the first and second frames, respectively, can be rotated in two mutually perpendicular planes, normal controlled surfaces, of which one is parallel to the axis of the workpiece, the first and second guides are mounted on the first and second cart, respectively, the second sensor is installed on the second carriage, the scan amplitude
