Abstract:
1. Method for temperature control of a high temperature metallic strip in a continuous metal casting plant wherein liquid metal is poured into an ingot mould consisting of a pair of cooled, counter rotating rolls, solidifies upon contact with said rolls and is extracted from the ingot mould in the form of a high temperature strip, said strip following, below said ingot mould, a free path, firstly descending and then ascending forming, in such a manner a loop, passing then on a roll conveyor with cooled rolls, drawn by at least a pair of drawing rolls, and is then wound into coils by a coiling device, characterised by the stages of: (i) controlling and regulating the heat exchange towards the environment by the strip which forms the loop, (ii) controlling and regulating the supply of cooling fluid fed to said rolls in the roll conveyor, (iii) controlling and regulating the heat exchange with a series of rolls put into contact with the strip above it, (iv) recording the signals from an array of temperature sensors placed along the strip between the exit from the ingot mould and the entrance into said coiling device, and (v) sending said signals to an electronic computing device, which computes the data received and accordingly regulates the stages from (i) to (iii).
