Definitions
- the invention relates to a continuous steel casting mold with two oppositely arranged, cooled broad side walls and between the broad side walls with adjustable play arranged narrow side walls, a one-piece narrow side wall being pivotally arranged on a spacer plate clamped between the wide side walls and displaceable for setting the format.
- a spacer plate is clamped between broad side walls by pressure medium cylinders and is adjustable by a spindle drive.
- An axis is arranged on the underside of the spacer plate, on which a narrow side wall is pivotably mounted.
- a spindle drive for conicity adjustment is attached to the top of the spacer plate, the spindle of which is connected to the top of the narrow side wall.
- the dimension of the spacer plate determining the mold opening width is up to 2 mm larger than the narrow side wall width. The conicity of the narrow side wall on the mold entrance side is adjusted according to the changes in the casting parameters, while the distance between the narrow side walls remains largely constant at the mold exit.
- Chill molds are used in which the conicity is adjusted by pivoting the underside of the narrow side wall, the upper distance between the narrow side walls remaining constant.
- Such a mold has been further developed by EP-A 1 114 293 in such a way that an adjusting device for the underside of the narrow side wall is actuated to generate a force counteracting the bulge and to keep this force constant, taking into account the friction between the narrow side wall and the broad side walls. Knowledge of the frictional forces is required for this.
- a continuous steel caster for billets and blooms which consists of a format-forming upper part with rigid walls and a spaced lower part with spaced movable walls.
- the movable walls are either articulated in the middle part of the mold on the underside of the rigid walls or on a carrier arranged below the upper part and can be adjusted resiliently against the strand. With this complex mold, uniform cooling and support is not guaranteed over the entire mold height.
- the object of the invention is to provide a break-proof steel continuous casting installation in which uniform heat dissipation of the narrow sides of the strand is unaffected by the strand shrinkage and changes in casting speed.
- the narrow side wall adjustment device is to be improved in such a way that a delay-free adaptation of the taper of the narrow side wall to the actual strand shrinkage, which is not influenced by frictional forces, is achieved.
- the aim is to simplify the adjustment drive of the narrow side wall.
- the narrow side wall is articulated on its upper side to the spacer plate and can be adjusted resiliently against the cast strand below the articulation point.
- the taper of the narrow side walls is adapted without delay to the changing strand shrinkage, the strand dimension remaining constant. If the width changes during casting, the narrow side wall automatically adapts to the strand contour. As a result, a common drive for the upper and lower adjusting spindle of the narrow side wall can be used instead of individual drives.
- a spring element is arranged below the articulation axis between the spacer plate and the narrow side wall, one or two adjusting elements being connected to the spacer plate.
- an upper adjusting element can be connected to the spacer plate, a lower adjusting element being passed through an opening in the spacer plate and acting on the narrow side wall via a spring element.
- a pressure medium cylinder can advantageously be provided as the spring element.
- the current inclination of the narrow side wall is determined by an inclinometer.
- the width of the narrow side walls and spacer plates can be less than 70 mm.
- the broad side walls can be expanded in a funnel shape to form a pouring area.
- Such a continuous casting mold can be used for casting thin steel strips of 20 to 70 mm in thickness at casting speeds above 2.5 m / min.
- a narrow side wall 3, 4 and a spacer plate 5, 6 are each connected to the casting side of the mold by a joint 13.
- adjusting mechanisms 14 are arranged on the frame 8, the adjusting elements 15 of which are attached to the rear of the spacer plates 5, 6.
- a lower adjusting element 16 is attached to the rear of the spacer plate 5.
- a pressure-controlled cylinder 17 is arranged as a spring element, the piston 18 of which acts with a defined force against the back of the narrow side wall 3 when pressurized.
- the distance plate 5 can also be adjusted via a single central adjustment element 16a.
- a lower adjusting element 19 is passed through an opening in the spacer plate 6 and is provided on the end face with a pressure-controlled cylinder 20, the piston 21 of which acts against the rear side of the narrow side wall 4 with a defined force.
- the narrow side walls 3, 4 adapt without delay to the contour of the narrow sides of the strand during casting, both with changed strand shrinkage and with changes in the strand width according to the program.
- a hook connection 22, 23 with a limited freedom of movement is provided between a spacer plate 5, 6 and the associated narrow side wall 3 or 4 as a pivoting limitation.
- the respective inclination of the narrow side wall 3, 4 is indicated by an inclinometer 24.
- the narrow side walls 3 ', 4' and the spacer plates 5 ', 6' have a width less than 70 mm.
- the broad side walls 1 ', 2' are expanded in a funnel shape to form a pouring region 25.
