摘要： A method for continuous casting of metallic strands which provides a maximum compressive stress to the strand at the precise bending point of the strand guide. In this manner, continuous casting speeds of greater than 0.8 m/min. can be utilized without the otherwise present potential for ruptures and tears. Pairs of supporting rollers are spaced along the strand guide. A bending point is defined as the precise point where the arcuate section of the strand guide becomes the linear section of the strand guide. It is at that bending point that the compressive forces on the cast metallic strand are maximized by the selected driving of the supporting rollers, located downstream of the bending point. The number of supporting rollers located upstream of the bending point is not less than twice the number of supporting rollers located downstream of the bending point.

摘要： Molten steel is poured into a water cooled continuous casting mold in which the steel solidifies partially with the formation of a strand having a length and a peripheral shell. The strand has a cross-sectional surface area with one of a round shape, an oval shape and a polygonal shape having more than four sides. Additionally, the strand has a minimum circumference of 200 mm. The cross-sectional surface area of the strand leaving the mold is then reduced using rolls before the strand fully solidifies. The reducing includes deforming the strand into a polygonal shape having at least four corners while maintaining the circumference as well as the length of the strand at the peripheral shell constant.

摘要： A continuous casting installation for producing thin slabs includes a laterally adjustable mold in which an immersion nozzle protrudes. In the mold there is opposite a larger crowned cross section on the charging side a cross section on the strand outlet side which is small and identically crowned in the central region. The installation further has pairs of supporting and guiding rollers which follow the mold and have a caliber adapted to the emerging crowned strand. The broad-face parts have planar-surface central parts which are arranged parallel to one another along their widths and taper toward one another in the casting direction of the strand. The broad-face parts also have planar side surfaces arranged so that they taper conically toward each other in the direction of the narrow faces. The planar-surface central plate is connected to the planar-surface side surfaces by transitional parts. The transitional parts taper toward each other in the form of a wedge and the wedge tip ends at a distance (a), measured from the upper edge of the mold, with a=0.5 to 0.8×L, where L=the length of the mold. The supporting and guiding rollers have a contour which corresponds to the planar-surface central plate and the planar side plates of the mold broad faces in the region of the mouth of the mold.

摘要： A method for continuous casting of thin slab ingots with reduced thickness following immediately the casting particularly of steel under utilization of a mold which is open at the bottom and under further utilization of roller pairs arranged along the withdrawal path, at least some of them are driven and at least some of the rollers are hydraulically adjustable perpendicular from the path so as to act as ingot deforming rolls. The invention is further improved by determining the speed of driven rollers, and the pressure force of adjustable roller pairs acting against the ingot and providing feedback control for the speed and the force. Additionally, providing a master control action for the speed control such that a point of solidification is dynamically maintained in a particular geometric position as far as the passing ingot is concerned; and by limiting the adjustment of rollers as far as the gap between pairs of such rollers is concerned downstream from that point.

摘要： A billet guide in continuous casting installations for producing slabs, in particular according to the continuous casting and rolling process, including rollers which are located across from one another in pairs can be adjusted to different billet thicknesses, and are supported at frame pans of the billet guide. The frame pans are connected by tie rods which are formed by piston-cylinder units. Spacers are placed between the upper and lower frame pans in the flow of force of the piston-cylinder unit. A hydraulic ring cylinder is arranged between the spacers and the cylinder of the piston-cylinder unit and encloses the piston. The ring piston of the hydraulic ring cylinder supports the spacer in a frictional manner.
