PURPOSE:To obtain a well shaped coil by cutting out unordinary parts at the initial and last stages of a thin strip carried from a cooling body, and cooling the strip to roll it before taking it up into a coil. CONSTITUTION:Shears 4, 4', a changeover gate 6, a chute 7 and a bag 6 are respectively disposed in the vicinity of cooling rolls 3, 3' rotating at high speed as a cooling body. A molten metal flow 2 discharged from a pouring nozzle 1 is quenched and solidified into a thin strip 5 by the cooling rolls 3, 3'. As a normal thin strip 5 cannot be obtained in the initial stage of solidification and the finishing stage of pouring, the unordinary parts of strip 5 at said stages are cut out as crops by using the shears 4, 4' and the gate 6, and are separated by falling it from the chute 7 into the bag 8. By this method, the normal part of thin sheet 5 is held between sheet-passing devices 9, 10 and is taken up into a well shaped coil 19 by a take-up reel 20. |
