Method and device for regulation of the height of the level of coulee in the shells of the continuous coulee

摘要

Opere the process for detection of the variations of the level of coulee according to the principle of eddy currents, a high frequency alternating magnetic field induces, in two coils receiving secondary, of the voltages, the differential voltage resultant is made in the same assignee has zero for the height at the level of the liquid, and the voltage created when the level of coulee is departs of the assignee given height which is used for the regulation. / p & & p & the device comprises two secondary coils receiving 3 and 4, montees in opposition, attached to a primary winding 2 connected to the high frequencies 1, and a compensation coil 5 and a coil 6 connected to the probe 7 which serves for the detection, which are respectively mated to the coils receiving. / p & & p & it is possible to use this to coulee of bars made of copper, brass.
