摘要： PCT No. PCT/AU97/00133 Sec. 371 Date Sep. 10, 1997 Sec. 102(e) Date Sep. 10, 1997 PCT Filed Mar. 6, 1997 PCT Pub. No. WO97/34718 PCT Pub. Date Sep. 25, 1997A casting pool (30) of ferrous molten metal is supported on a pair of chilled generally horizontal casting rolls (22) forming a nip (27) between them. The casting rolls (22) rotate mutually opposite directions to produce a solidified metal strip (12) moving downwardly from the nip (27). The strip (12) passes along a transit path (10) which takes it away from the nip (27) in an unrestrained loop (29) disposed within a strip enclosure (38) within which the strip is confined through said transit path (10). The strip (12) moves downwardly from the nip (27) to form the unrestrained loop (29) passes between a pair of cooled non-contact heat absorbers (101) to which heat is radiated from the strip (12) whereby to extract from the strip heat generated by completion of solidification of metal therein after leaving the casting pool (30). Heat absorbers (101) are formed as opposite side walls of a cooling collar (100) defining an upper part of enclosure (38) and provided with cooling water ducts (102).

摘要： A molten metal casting pool is confined between a pair of casting rolls (12) by side closure plates (18) applied to the ends of the rolls (12) by thrusters (21). Side closure plates (18) are mounted in holders (25) which are pivotally connected to thrusters (21) by pivot pins (26) so that the side plates (18) can tilt about the pivot connections. Pivot pins (26) are located at such height above the nip between rolls (12) that effect of outward pressure on plates (18) by molten metal of the casting pool is such as to rotationally bias the plates (18) about the pivots in such directions that their bottom ends are biased inwardly to produce increased scaling pressure at bottom of casting pool.

摘要： PROBLEM TO BE SOLVED: To restrain the development of scale and reduce the consumption of non-oxidizing gas by enclosing a strip into an enclosure and moving out the moving path out at a specified temp. or lower. SOLUTION: The upper cover 26b of a shutter 26 is lowered and abutted on the lower cover 26a and the opening degrees of flow rate adjusting valves 38a-38d are set. When the inner parts of an upstream side chamber 19 and a downstream side chamber 24 becomes non-oxidizing gas atmosphere, molten metal is supplied into a tundish 3 and the strip 4 is cast. When the tip part of the strip 4 passes through first pinch rolls 17a, 17b, nozzle group 22a, 22b is moved to the using position. A pump 41b is operated and the opening degree of the flow rate adjusting valves 34a, 34b are suitably adjusted and cooling liquid 42 is injected from the nozzle group 27a, 27b to rapidly cool the strip so as to move it out to the moving path at

摘要： PROBLEM TO BE SOLVED: To improve the sealability between casting roll end faces and side plates. SOLUTION: A molten metal pool is confined between a pair of the casting rolls 12 by the side plates 18 pressed to the ends of the casting rolls 12 by thrusters 21. The side plates 18 are supported by side plates holders 25. The side plate holders 25 are pivotally connected to the thrusters 21 by pivot pins 26 in such a manner that the holders can tilt about the pivotal connections. The pivot pins 26 are located at a height above the roll gap level between the casting rolls 12. The height is so that effect of outward pressure applied on the side plates 18 by the molten metal of the casting pool rotationally presses the side plates 18 above the pivot pins 26 in such directions that their bottom ends of the side plates 18 are pressed inwardly to produce increased scaling pressure at the bottom of the casting pool.
