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： A process for sintering an iron ore blend of iron ore particles, the iron ore blend comprises soft/porous ores is disclosed. The process comprises forming a green mix of the iron ore blend and a flux; granulating the green mix with water; and sintering the granulated green mix. The process is characterised by a treatment step to inhibit absorption of water into the soft/porous ores.

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.

摘要： A self-tapping rock bolt comprises a discontinuous threaded profile (9) having a plurality of cutting edges (11) and at least one flute (13) extending along the length of the rock bolt. The cutting edges (11) are adapted to cut a threaded profile in the internal surface of a pilot hole so that the threaded profile (9) of the rock bolt interlocks therewith. The or each flute (13) is adapted to facilitate removal of material cut by the cutting edges (11). A preferred embodiment of the rock bolt includes an internal axial hole (25) to enable water to be injected through the rock bolt as the threaded profile is being cut. A self-tapping and self-drilling rock bolt comprises the self-tapping rock bolt described above and a cutting means (23) to cut a hole for the rock bolt.

摘要： Boulon de rocher autotaraudeur comprenant un profil fileté discontinu (9) ayant plusieurs arêtes de coupe (11) et au moins une cannelure (13) s'étendant sur la longueur du boulon de rocher. Les arêtes de coupe (11) sont conçues pour découper un profil taraudé dans la surfce interne d'un trou pilote, de sorte que le profil fileté (9) du boulon de rocher s'engage avec le profil taraudé de la surface interne. Ladite cannelure ou chacune d'entre elles (13) est (sont) conçue(s) pour enlever plus facilement le matériau découpé par les arêtes de coupe (11). Dans une réalisation préférée, le boulon de rocher comprend un trou axial interne (25) permettant d'injecter de l'eau à travers le boulon de rocher pendant la découpe du profil taraudé. Un boulon de rocher autotaraudeur et autoperceur comprend un boulon de rocher autotaraudeur du type de celui décrit plus haut et un dispositif de découpe (23) permettant de creuser un trou pour le boulon de rocher.

摘要： A wrapping apparatus whereby a wrapping medium (30) may be applied to an annular article, such as a coil of metal strip (46), so as to cover its inner surface as well as all its outer surfaces comprises a rigid loop structure that defines an endless T-sectioned track (16,17) and extends as a cantilever extending from a free standing columnar support (5,6). The columnar support (5,6) includes elevator means for raising and lowering the loop structure. The loop structure includes a hinged gate portion (9) that may be swung into an open position to enable the track (16,17) to be linked with the annular article and then reclosed. A self propelled shuttle (15) is able to ride around said track.
