摘要： PURPOSE:To prevent the development of surface defect by blowing inert gas on surface of drums just before the surfaces of cooling drums shift to outer air shut-off area in pouring basin part at the time of producing a cast strip by forming the pouring basin part shut off from the outside air between one pair of the cooling drums. CONSTITUTION:Just before the cooling drums 3a, 3b shift to the outside air shut-off area 10 in the pouring basin part 4, the inert gas is blown against the above cooling drums 3a, 3b. The thin air layer on surface of the cooling drums 3a, 3b is shut off with the gas and further, air in dimples can be removed and atmosphere in a seal chamber 6 can be perfectly made to inert gas atmosphere. By this method, as the atmosphere in the pouring basin part can be made to more perfect non-oxidizing atmosphere, the oxidation on the molten metal surface is reduced and surface defect caused by involution of scum can be prevented and the cast strip having excellent quality can be produced.

摘要： PURPOSE:To produce a thin cast billet having the objective projecting crown at good accuracy by measuring the profile of the thin cast billet sent out from drum gap and adjusting the flow rate of cooling water based on the measuring result. CONSTITUTION:The molten metal 4 poured in pouring basin part 3 is rapidly cooled and solidified on circumferential surfaces of the cooling drum 1a, 1b to make this the solidified shells and welded and integrated with the drum gap 5 and sent out as the thin cast billet 6. The thickness of the thin cast billet 6 is measured in the lateral direction to detect the profile of the thin cast billet 6. This detection result is inputted to a computing element 10, and by comparing with the reference information and operating, the flow rate of the cooling water corresponding to the crown rate of the thin cast billet 6 during production is calculated. By this calculated value, a flow rate adjusting value 13 disposed on the way of a water supplying pipe 12 for supplying the cooling water 11 is adjusted. The cooling water 11 having the flow rate adjusted in such a manner is guided into the cooling drums 1a, 1b to control the crown of the thin cast billet 6.

摘要： PURPOSE:To let rolling to good shapes be accomplished by providing rolling pressure detectors and shape detectors and controlling screw-down devices, roll benders and roll shifters. CONSTITUTION:A closed loop control unit 20 detects the rolling forces at both ends of rolls with detectors 121, 122 and controls the level and roll bending forces of screw-down positions. A closed loop control unit 21 is inputted with various rolling condition quantities, selects at least two factors out of roll movement positions, roll bending forces and screw-down positions and determines and controls the optimum correction quantities. A non-interference control uunit 19 regulates the speed of an un-coiler so that thicknesses do not change, with respect to the output values of the screw-down position correcting quantities of an open loop control unit 20 and a closed loop control unit 21 and regulates roll bending forces so tat shapes do not change with respect to the screw-down position correcting quanties of an automatic thickness control unit 18. A roll temperature control unit 22 detects the rotating speed of the coiler and controls the temperature of the rolls constant from the volume of cooling water.
