20090126895 | MOLTEN METAL FEED NOZZLE - A nozzle end is provided with an extension | 05-21-2009 |
20090255644 | TWIN ROLL CASTER - A twin roll caster including chilled rolls, side weirs, and a molten-metal delivery nozzle. Baffles, contiguous with bottoms of end faces of the nozzle, project in a casting pool toward the side weirs to suppress stream of the molten metal into a nip between the rolls. Thus, hot molten metal just after poured into the pool does not instantly reach the nip along the side weirs, and molten metal decreases in temperature with lapse of time after the pouring streams into the nip as the rolls are rotated. As a result, belated formation of solidified shells at and adjacent to outer circumferential edges of the chilled rolls is eliminated. Thus, a strip delivered from the nip between the rolls has no reduced thickness at regions adjacent to lateral edges of the strip and has uniform thickness throughout the width of the strip. | 10-15-2009 |

20100236747 | Brush Roll for Casting Roll - A metal strip casting apparatus and method of casting metal strip include assembling a pair of counter-rotatable casting rolls positioned laterally forming a nip between for casting, and assembling a pair of brush rolls, each of the brush rolls associated with one of each of the casting rolls. Each brush roll includes at least one spaced apart brush line extending substantially along the axial length of the casting roll. The brush lines may form a spiral, zigzag, wave or crisscross array about the brush roll. The brush roll may include one or more staggered rings with regularly or irregularly spaced apart bristles which form the brush lines. The brush lines may be between 10 to 50 mm apart and separated by between 2 mm to 45 mm of open space. The brush lines may be one line per 10 mm to 90 mm of axial length of brush roll. | 09-23-2010 |
