Abstract
Abstract An adjustable plate mold for continuous casting incorporating a support frame and longitudinal walls and transverse walls supported at the support frame, said longitudinal walls and transverse walls limiting the mold compartment. The longitudinal walls are slidingly arranged at the side facing away from the hollow mold compartment upon support plates for expansion and contraction and the transverse walls are equipped with adjustment devices supported by the support frame. The adjustment devices positively are connected, on the one hand, with the transverse walls and, on the other hand, with the support frame in the adjustment directions. Exchangeable impact or stop gauges corresponding to the momentary reference value of a mold dimension are provided between the transverse walls and impact or stop surfaces at the support frame and the transverse walls can be fixedly clamped between the longitudinal walls. Each adjustment device has associated therewith a coupling for interrupting the positive connection. During the casting operation this coupling permits movement of the associated fixedly clamped transverse wall with respect to the impact surfaces in the direction of the mold compartment and back again.

Claim 1
Independent Claim
197 words
An adjustable plate mold for continuous casting, comprising a support frame having stop surface means, a mold formed by longitudinal walls and transverse walls for limiting a mold compartment thereof, said mold being provided with cooling devices, said longitudinal walls and transverse walls being supported by the support frame, support plates upon which the longitudinal walls are slidingly arranged at the side facing away from the mold compartment for expansion and contraction, adjustment devices provided for the transverse walls, said adjustment devices being supported by the support frame, said adjustment devices being connected with the associated transverse wall and with the support frame, exchangeable stop gauges provided between the transverse walls and the stop surface means at the support frame, said exchangeable stop gauges corresponding to a desired mold dimension during casting operation, said transverse walls being fixedly clampable between the longitudinal walls, coupling means operatively associated with each adjustment device for interrupting the connection between the associated transverse wall and the support frame, said coupling means during the casting operation permitting movement of the associated fixedly clamped transverse wall with respect to the stop surface means in the direction of the mold compartment and back again.
Claim 2
Dependent Claim
197 words
An adjustable plate mold for continuous casting, comprising a support frame having stop surface means, a mold formed by longitudinal walls and transverse walls for limiting a mold compartment thereof, said mold being provided with cooling devices, said longitudinal walls and transverse walls being supported by the support frame, support plates upon which the longitudinal walls are slidingly arranged at the side facing away from the mold compartment for expansion and contraction, adjustment devices provided for the transverse walls, said adjustment devices being supported by the support frame, said adjustment devices being connected with the associated transverse wall and with the support frame, exchangeable stop gauges provided between the transverse walls and the stop surface means at the support frame, said exchangeable stop gauges corresponding to a desired mold dimension during casting operation, said transverse walls being fixedly clampable between the longitudinal walls, coupling means operatively associated with each adjustment device for interrupting the connection between the associated transverse wall and the support frame, said coupling means during the casting operation permitting movement of the associated fixedly clamped transverse wall with respect to the stop surface means in the direction of the mold compartment and back again.
Claim 3
Dependent Claim
22 words
The mold as defined in claim 1, wherein said coupling means is arranged between the associated adjustment device and the support frame.
Claim 4
Dependent Claim
21 words
The mold as defined in claim 1, wherein said coupling means is arranged between the associated adjustment device and transverse wall.
Claim 5
Dependent Claim
82 words
The Mold as defined in claim 2, wherein the support frame has a supporting surface, the adjustment device being a spindle adjustment device incorporating a spindle, a disk threadably connected with the spindle, said disk being slidingly supported at the support frame in the axial direction with respect to the spindle, a pre-biased package of springs arranged between the supporting surface of the support frame and said disk such that the spring force presses the associated transverse wall towards the stop gauges.
Claim 6
Dependent Claim
42 words
The mold as defined in claim 2, wherein the adjustment device is a spindle adjustment device having a spindle, said coupling means comprising a coupling element cooperating with the spindle for selectively disconnecting and connecting the spindle with the associated transverse wall.
Claim 7
Dependent Claim
43 words
The mold as defined in claim 3, wherein the adjustment device is a spindle adjustment device having a spindle, and said coupling means comprises a coupling element cooperating with the spindle for selectively disconnecting or connecting the spindle with the associated transverse wall.
Claim 8
Dependent Claim
159 words
In an adjustable plate mold for continuous casting, comprising a support frame having at least one stop surface, a mold formed by longitudinal walls and transverse walls clamped between the longitudinal walls for limiting a mold compartment thereof, said longitudinal walls and transverse walls being supported by the support frame, adjustment means provided for at least one of the transverse walls, said adjustment means being supported by the support frame, said adjustment means being connected with said at least one transverse wall and with the support frame, exchangeable stop gauge means provided between said at least one transverse wall and the stop surface, and coupling means provided for said adjustment means for interrupting the connection between said at least one transverse wall and the support frame, said coupling means during the casting operation allowing for movement of said at least one transverse wall with respect to the stop surface in the direction of the mold compartment and back again.
