  • Twin-Roll Continuous Casting Machine And Twin-Roll Continuous Casting Method
    Publication number: 20080169082
    Abstract: When a molten steel (106) is supplied into a moving mold defined by concave rolls (101, 102) and side checks (103, 104), the molten steel (106) is cooled by the surfaces of the rolls (surfaces except steps) to form solidified shells (111, 112). Both solidified shells (111, 112) are pressure bonded, and pulled out as a cast piece (113). A heat insulator (ceramic coating) has been applied to the circumferential surfaces of steps (101a, 101b, 102a, 102b) which are opposite end portions of the rolls. Thus, at these portions, heat dissipation does not proceed, and no solidified shells are formed. Hence, clearances are formed between the opposite ends of the solidified shells (111, 112) and the side checks (103, 104), and the solidified shells (111, 112) do not contact the side checks (103, 104), with the result that the wear of the side checks (103, 104) is prevented.
