摘要： A system and method for continuous casting. The system includes a melt chamber, a withdrawal chamber, and a secondary chamber therebetween. The melt chamber can maintain a melting pressure and the withdrawal chamber can attain atmospheric pressure. The secondary chamber can include regions that can be adjusted to different pressures. During continuous casting operations, the first region adjacent to the melt chamber can be adjusted to a pressure that is at least slightly greater than the melting pressure; the pressure in subsequent regions can be sequentially decreased and then sequentially increased. The pressure in the final region can be at least slightly greater than atmospheric pressure. The differential pressures can form a dynamic airlock between the melt chamber and the withdrawal chamber, which can prevent infiltration of the melt chamber by non-inert gas in the atmosphere, and thus can prevent contamination of reactive materials in the melt chamber.

摘要： The invention relates to metal solidification and continuous casting, in particular to a back-up roll device and method for conducting corner deformation on a chamfered continuous casting slab. The back-up roll device comprises back-up rolls with α-angle bevels, movable bearing seats, bearing seat moving rails, bearing seat motion holding mechanisms and inner arc or outer arc frames of a casting machine. The back-up rolls are arranged on the inner and/or outer arc frames of the horizontal segment of the casting machine. Support surfaces of the back-up rolls make contact with and squeeze smaller obtuse angles adjacent to the wide face of the inner or outer arc on the chamfered continuous casting slab, and therefore each smaller obtuse angle is squeezed into two larger obtuse angles. The back-up roll device and method for conducting corner deformation on the chamfered casting slab can achieve the purposes of eliminating edge slivers.

摘要： Pinch roll apparatus has a pair of pinch rolls, each having a diameter between 300-1500 millimeters, positioned to form a nip through which metal strip can be continuously fed. The pinch rolls are positioned one above the other with the axes of the pinch rolls offset in the direction of travel of the strip, with the upper pinch roll offset positioned between 10 and 130 mm downstream of the direction of travel of the strip through the pinch rolls. A rotational drive counter-rotates the pinch rolls to cause strip to pass through the nip of the pinch rolls. A tilt drive tilts the upper pinch roll by a tilt between 0.5 and 5.0 mm to control steering of the strip passing through the pinch rolls. The steering of the tilt drive may be automatically controlled through a controller actuated by a sensor.

摘要： A method for producing steel slabs, whereby the strand leaves an ingot mold with melt enclosed by a strand shell and, in a strand guide located downstream, the opening width of guide rolls mounted in segments with upper and lower frames can be set in a continuous manner with successive steps by adjusting elements that join said guide rolls. An oscillation around a center line of the opening width serves to modify the opening width in order to render the dynamic influences on the guide rolls negligibly small. The amplitude of the opening width oscillation is set to ta quantity, which des not provoke any plastic deformation of the strand shell. The actual opening width of the guide rolls is detected and the actuating force of the adjusting elements as well as the amplitude of the actuating force are determined at the same time. In the case of an increasing amplitude of the actuating force, the opening width is set to a predeterminable measure and/or guided in a pressure controlled manner via at least one adjusting element. A force/path diagram of the opening width setting is then determined form a multitude of force/path measurements along the strand. Said diagram is composed, in a chain-like manner, of a multitude of small force path curves, which are each provided in the form of a hysteresis and which can be individually determined using an oscillation with a comparatively small amplitude.

摘要： A strand guiding segment for slab casting plants with a guiding width for the cast strand is adjustable between guide rollers of a frame on a fixed side and a frame on a detachable side, wherein the frames interact with adjusting units for overcoming the ferrostatic pressure and for adjusting the desired sectional width of the strand. The adjusting units are four independently adjustable pressure cylinders arranged outside of the radiation range at the upper side of the segment, wherein the distance between the segment middle and cylinder which determines the segment width is reduced on both sides by the dimension of the cylinder which has been moved to the upper side of the segment. The segment crossbeams are provided with radiation protection plates instead of water cooling means and cooled side frames are laterally flanged to the bottom frames.

摘要： A billet guiding unit of a continuous casting plant for thin slabs includes guide rolls supported on oppositely located frames, wherein the frames are tensioned relative to each other against stop surfaces by means of tension rods. Hydraulic cylinders for extending or stretching the tension rods are mounted between corresponding stop surfaces of the frames. The distance between oppositely located rows of rolls of the frames are corrected by determining a lower deviation side of the slab by carrying out a continuous measurement of the thickness of the slab sides, by determining from the difference of the dimensions the required extension of the tension rods on the lower deviation side and by applying to the hydraulic cylinders the pressure required for the extension of the tension rods.

摘要： Multiple pairs of pinch rolls are used to advance a rod product along a pathway following a continuously casting and rolling system. Each pinch roll pair exerts a force normal to the rod of less than the amount necessary to substantially degrade the yield strength characteristics of the finished rod. Multiple driven pinch roll pairs cooperate to advance the rod by compressive engagement and accomplish the work of one or two pairs of pinch rolls to minimize work hardening and/or plastic deformation, which can result in an increase in yield strength. Yield strength characteristics are thus improved while the continuous rod product is still advanced and guided at very high speed along a pathway from a horizontal to a vertical direction.
