Abstract

PURPOSE:To uniformize thickness of a hoop by arranging thermometers respectively near casting surface in inner part and at inner part of the cooling roll and operating heat crown based on this temp. difference. CONSTITUTION:In the inner part of one pair of cooling rolls 3, the thermometers 4, 4' are arranged at the position near the casting surface and at the position of inner part, respectively. Further, temp. detecting signals 5 of the thermometers 4, 4' are introduced into an arithmetic unit 6 at outside through axial center of the rolls 3. Before continuous casting through the rolls 3, precasting is executed and then, thermo crown of the rolls 3 is measured through a shape-meter 7 or a thickness detector 8, and the detecting signal 9, 10 is inputted to the arithmetic unit 6. By comparing the difference of the detected temp. with the thermometers 4, 4' and the pre-found heat crown, the heat crown of the rolls 3 is corrected with a cylinder 12 and a control device 14. By this method, the thickness of the hoop 2 is uniformized.
