Abstract

An apparatus for the adjustment of cooling for a continuous ingot casting machine of the type comprising a rotating casting wheel provided with a peripheral channel or mould which is covered along a certain arc by a metal tape, said apparatus comprising means responsive to the temperature of said mould arranged at the noncovered portion of said channel, and adjustment means arranged to be actuated by the temperature responsive means in order to adjust cooling means for cooling said mould.

Claims

1. An apparatus for the adjustment of cooling for a continuous casting machine of the type including a turning wheel provided with a peripheral casting channel which has a portion thereof covered by a metal tape and a noncovered portion thereof, cooling means for said channel and control means for controlling the cooling intensity of said cooling means, wherein according to the improvement the apparatus further comprises temperature sensing means arranged in the reach of the noncovered portion of said peripheral channel and sensing the temperature thereof, said control means being responsive to the temperature of said noncovered portion of the casting channel sensed by the sensing means.

2. An apparatus as claimed in claim 1 wherein said casting channel has a bottom and wherein, according to the improvement said sensing means comprise a ribbon thermocouple sliding on the bottom of the noncovered portion of said peripheral casting channel and near to the filling point of the molten metal.

3. An apparatus as claimed in claim 2, in which said cooling means comprises a plurality of nozzles directing the cooling fluid on portions of said casting channel and said tape, and in which said control means comprises an axial feed pipe for the cooling fluid and a valve in said axial feed pipe for controlling the flow of cooling fluid therethrough, an electric motor with adjustably phase voltage and having transmission means connected with said valve, a modulator adapted to adjust the phase voltages of said motor, an amplifier having its input connected to said thermocouple and controlling said modulator, said motor being adapted to adjust said valve when its phase voltage is adjusted by said modulator.

4. An apparatus as claimed in claim 2 wherein said temperature sensing means comprises a thermocouple emitting a tension intensity signal, responsive to the temperature sensed, a transductor connected therewith and transforming said tension intensity signal into a current intensity signal, a converter connected therewith and transforming said current intensity signal into a pressure intensity signal and wherein said control means include a pneumatically operated regulating instrument and a valve controlling the flow of cooling fluid for said channel, said regulating instrument being connected with and controlling said valve responsive to said pressure intensity signal from said converter.

5. An apparatus as claimed in claim 4 wherein said pneumatically operated regulating instrument comprises a recording section continuously recording the signals received.
