摘要： Continuous casting of steel strip in twin-roll caster comprises casting rolls (16). Molten steel is delivered by a delivery system and comprising delivery nozzle (19b) to casting pool (30) supported above nip (10) between the casting rolls (16) which are rotated to deliver a solidified strip (20) downwardly from the nip. To avoid dissolution of carbon from refractories of the metal delivery system including the nozzle (19b), the molten steel is a silicon/manganese killed carbon steel having a manganese content of not less than 0.02% by weight, a silicon content of not less than 0.10% by weight, an aluminium content of less than 0.01% by weight and a sulphur content of at least 0.02% by weight. The required sulphur content of the steel may be achieved by addition of iron sulphide to a batch of steel in a tundish (18) of the delivery system.

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： A method and an apparatus for pyrolysing a solid organic feed material are disclosed. Solid organic material is moved through a reaction chamber and exposed to a temperature profile within the chamber that dries and pyrolyses the organic material and releases water vapour and a volatile products gas phase. The water vapour phase and the volatile products gas phase are moved counter-current to the solid organic material so that the water vapour phase and condensable components of the volatile products gas phase condense in cooler upstream sections of the chamber and form a liquid water product and a separate liquid oil product. The liquid water product is discharged via an outlet along the length of the chamber and a dried and pyrolysed solid product is discharged from a downstream outlet in the chamber.

摘要： In twin roll casting of steel strip, molten steel is introduced into the nip 16B between parallel casting rolls to create casting pool supported on casting surfaces of the rolls and the rolls are rotated to deliver solidified strip downwardly from the nip. Casting surfaces are textured by a random pattern of discrete projections, which may have an average surface distribution of between 5 and 200 peaks per mm2 and an average height of at least 10 microns. In order to suppress chatter defects, the molten steel also has manganese content of at least 0.55% by weight and a silicon content in the range of 0.1 to 0.35% by weight. The strip is thus capable of moving away from the casting pool at a speed of more than 60 meters per minute without substantial high speed chattering defects.
