摘要： Method and apparatus for steering a strip along a desired path. The strip 12 is fed along a guide table 13 by a pair of pinch rolls 50 which are of concave formation so as to grip the strip at two laterally spaced locations at the edges of the strip. A pair of fluid cylinder units 52 are independently operable to vary the pressures applied by the rolls at the two gripping locations to steer the strips. The position of the strip is monitored in the vicinity of the rolls 50 by a strip position sensor 51. Steering of the strip is controlled by a control signal derived from the output of sensor 51. The control signal in the sum of three factors the first of which is a measure of the instantaneous lateral traversing velocity of the strip and the third of which is an integration of instantaneous values of the lateral position of the strip over a preceding time interval.

摘要： Metal strip is cast from a casting pool of molten metal supported above the nip between a pair of chilled casting rolls (16). The casting pool is confined by refractory plates (56) engaging the ends of the rolls (16). Molten metal in the casting pool in the vicinity of the end closures (56) is subjected to electromagnetic induction heating by passing electric current through electrical conductors (101) disposed outside the refractory plates (56). Each conductor (101) is in the form of a trapezium shaped loop of metal tube having wide top segment (107) and narrow bottom segment (108) connected by downwardly convergent side segments (109) aligned with roll edges.

摘要： A structural member (12, 14, 16) for coupling to a similar structural member for forming a framework, the structural member comprising an elongate channel having a web (30) and first and second sidewalls (32, 33), the first sidewall having a transversely extending slot (40) and the second sidewall having a complementary tab (42), wherein the slot and tab are transversely aligned and are positioned and adapted to respectively engage a tab and slot of a similar structural member to thereby couple the structural members together. The dimensions of rail (14) are such that it can interlock with the formations on the upright channels (52, 54). The projections (82, 84) are received snugly within the openings (72, 76) respectively. The projecting legs (88, 86) are received within the slots (70, 74) respectively. The lengths of the slots (80, 78) are such that the end of the rail (14) abuts or lies adjacent to the faces (62) of the upright channels (52, 54). This provides an interconnection of the rail (14) with the upper ends of the upright channels (52, 54).

摘要： Casting metal strip by delivering molten metal to a casting pool (81) supported on a pair of parallel casting rolls (16) and passing metal downwardly between the rolls to produce solidified strip (20). Flow of metal to the casting pool (81) is controlled by an input flow control valve (47). At start of casting when pool (81) is being filled speed of rolls (16) is varied in response to variations between actual instantaneous poo level and predicted level until pool approaches desired operational level. Thereafter any variations between instantaneous roll speed and desired operational roll speed are caused to adjust valve (47) to being pool level and roll speed to desired operational valves.

摘要： Method of casting steel strip in which molten steel solidifies as a shell on a chilled casting surface (100). The casting surface (100) has a texture (101) formed by a regular pattern of surface projections (103) and depressions (102) and the steel chemistry is selected to generate in the casting pool deoxidation products which form on the casting surface (100) a layer of less than 5 microns thickness a major proportion of which is liquid during cooling of the steel to below its liquidus temperature in the formation of said solidified shell. The substantially liquid layer suppresses the formation of surface defects in the solidifying metal surface due to early deposition of solid oxides on the casting surface.

摘要： To suppress generation of scales on surfaces of a strip and to reduce the amount of non-oxidising gas consumed in the casting of strip in a twin roll caster there is provided downstream apparatus comprising pinch rolls 17a and 17b for pinching a strip 4 continuously cast by a pair of casting rolls 1a and 1b, a coiler 8 for coiling the strip 4 delivered from the pinch rolls 17a and 17b, an upstream chamber 19 for enclosing a travelling path of the strip 4 from the casting rolls 1a and 1b to the pinch rolls 17a and 17b, a downstream chamber 24 for enclosing a travelling path of the strip 4 from the pinch rolls 17a and 17b to a position before the coiler, a shutter on an end of the downstream chamber closer to the coiler and a gas supply source for supplying non-oxidising and reducing gases to the upstream and downstream chambers 19 and 24 and quenching means within the downstream chamber to cool the strip so that it leaves the chamber at a temperature of 300°C or below.

摘要： Steel strip (120) produced by a continuous strip caster (40) is treated as it comes from the caster and while it is in line with the caster by applying to the hot strip exiting the caster by means of a coater (201) an oxidation protective coating of a material which is fluid at the temperature of application and susequently removing the coating by a coating removal treatment which includes cooling of the coating by a cooler (204) to cause it to solidify and fracture. The coated strip may be hot rolled by rolls (203) before removal of the coating.

摘要： A steel strip (12) is continuously cast from a pool (30) of molten metal that is supported on one or more chilled casting surfaces (22A). The casting surfaces (22A) are moved to produce a solidified strip (12) moving away from the casting pool (30) along a transit path (10). The formation of scale on the solidified strip (12) as it passes through the transit path (10) is controlled by confining the solidified strip within an enclosure (37) from which oxygen is extracted by oxidation of the strip and which is sealed to control ingress of oxygen containing atmosphere.

摘要： A method and an apparatus of continuously casting metal strip (20) is disclosed. A casting pool (30) of molten metal is formed in contact with a moving casting surface such that metal solidifies from the pool (30) onto the moving casting surface. In addition, sound waves are applied to the casting pool of molten metal to induce relative vibratory movement between the molten metal of the casting pool (30) and the casting surface.
