Definitions
- the invention relates to a continuous casting mold for the continuous casting of a metal strand, in particular a steel strand, with broad side walls lying opposite one another and clamped between the broad side walls and displaceable along the broad side walls transversely to the casting direction, opposite narrow side walls narrowing in the casting direction in a wedge-like direction the broad side walls have a funnel-shaped pouring area which extends in the casting direction up to the mold end and wherein the narrow side walls are interchangeably arranged according to the thickness of the metal strand to be cast and wherein the positions of the narrow sides in each case by means of a narrow side adjustment system comprising an upper and a lower adjustment the center axis of the metal strand to be cast can be adjusted.
- a narrow side adjustment system comprising an upper and a lower adjustment the center axis of the metal strand to be cast can be adjusted.
- the adjusting device comprises an upper and a lower adjusting element in order to be able to clamp the side wall downwards between the two broad sides in accordance with the required inclination to the mold center. If the adjusting device does not attack at least substantially centrally on the side wall, lateral tilting moments are exerted on the side wall, which bring them out of the desired position and cause damage.
- the center axis of the Schmalirritellsystems by means of screw, which are arranged parallel to the center axis, aligned in the workshop on the center position of the respective casting thickness.
- the narrow side wall between the broad sides is held by friction in the clamping joint.
- the adjusting device can not be brought to the respective center axis of the side wall, since the guide tubes of the adjusting device are firmly welded in the mold.
- the frame parts of the mold often have to be disassembled into the individual parts, or individual water boxes are removed.
- water guide elements which in many cases do not have the mobility that would be required to compensate for the resulting from the change in thickness of the slab shifts the water box of the Losseite can.
- this object is achieved in that the Schmallabverstellsystem at least one at least substantially transversely to the central axis acting on the adjusting actuator and an adjusting device for adjusting the set of the at least one actuator positions of the upper and lower actuating device with respect to a predetermined reference position.
- the Schmallabverstellsystem at least one at least substantially transversely to the central axis acting on the adjusting actuator and an adjusting device for adjusting the set of the at least one actuator positions of the upper and lower actuating device with respect to a predetermined reference position.
- the adjusting device comprises a connecting means and / or a format piece for establishing a connection to at least one mechanical reference surface or for setting to an exact reference position for determining the casting thickness.
- the adjusting elements comprise two cylinders arranged transversely to the center axis, hydraulically or pneumatically actuated cylinders and / or drives operated by electric motors, in particular spindle drives.
- the cylinders and / or the electric drives can be actuated position-controlled.
- the adjusting elements comprise disc spring units and hydraulic plunger cylinders.
- the adjusting elements form a screw system, wherein the positions of the screws can be fixed by locknuts.
- the adjusting elements can advantageously be formed so long that they are accessible from the outside of the continuous casting mold.
- a displaceable water tank arranged on the loose side of the broad sides is integrated at least partially in a side frame area formed by the continuous casting mold and / or by a water pipe element receiving its displacement and supported in the side frame area is arranged freely above a side part of the injection mold.
- the water pipe element comprises a lateral expansion joint and / or a hose, in particular in conjunction with a rigid pipe piece, wherein in particular the ends of the pipe piece are designed spherical, in particular in conjunction with radially sealing sealing elements.
- less stainless steel sheet parts are required in the arrangement compared to the prior art.
- 1 is a plan view of a lateral region of a continuous casting mold, partially cut,
- FIG. 2 shows a sectional view of the narrow-side side region of the continuous casting mold from FIG. 1 along a sectional plane A - A and FIG
- Fig. 3 is a perspective view of the side portion of the continuous casting mold.
- a continuous casting mold for continuous casting of a steel strand in the direction of an arrow B (after deflection by 90 °, for example) comprises a support frame 1 for a fixed broad side part, in each case a support frame 2 for each of the two narrow side parts and one Support frame 3 for the movable broadside part (lot side).
- the support frame 1 carries a copper plate 4, which forms the fixed broad side of the casting funnel. On the narrow sides of each of the narrow side parts 1 2 belonging copper plates 5 are arranged, which are each attached to a support 6. The illustrated copper plate 5 corresponds to a selected casting thickness a.
- the support frame 3 carries a copper plate 4 '.
- Schmalkverstellsystem 7 which preferably has an upper provided with the reference numeral 8 and an underlying lower adjusting element 9, both of which serve to adjust the width of the casting strand, so move the copper plate 4 'in the direction of arrow C while doing the to maintain the required inclination of the copper plate 5 to form the sprue.
- the adjusting element 8 and the underlying adjusting element 9 by a connecting part 10 are coupled together.
- the adjusting elements 8, 9 are preferably present twice. If, after replacing the copper plate 5 with a copper plate of a different width a ', the position of a center axis 11 of the narrow side adjustment system changes, a shift in the direction of an arrow D is exerted on the entire system by simultaneous adjustment of actuators 12, 13 is oriented according to the thickness change of the slab in one or the opposite direction. In this case, the adjusting elements 12, 13 are supported in each case by stops or reference marks 14 on the connecting parts 10.
- the adjusting elements 12, 13 each comprise hydraulic or pneumatic cylinders or have an electric motor-operated threaded spindle.
- the adjusting elements 12, 13 preferably further comprise displacement sensors, or they are equipped with other means for detecting distances and / or positions and for influencing an adjustment element.
- the adjusting elements 12, 13 adjust the narrow sides 2 in each case with respect to the reference marks 14, in addition casting-thickness-dependent format pieces 15 can be used, which facilitate the adjustment.
- the reference marks 14 and the format pieces 15 together form an adjusting device or are part of an adjusting device.
- the entire Schmalinciverstellsystem 7 is integrated into a side frame portion 16 which extends laterally of the casting mold and the front edge of the support frame 1, d. H. the edge in the casting direction, at least substantially does not exceed.
- the water pipe element 17 comprises a lateral compensator, a movable one
- Hose for example, in conjunction with a rigid pipe section.
- the connecting elements may be provided on the connecting elements spherically shaped ends of radially sealing sealing elements.
- the sealing elements are for example O-rings.
- the pieces of pipe for example, have a "dogbone shape”.
- the mold is supported on a lifting system.
