Abstract
Abstract A built-up plate mold for continuous casting of slabs comprises a supporting frame and longitudinal and transverse mold walls. The transverse walls are normally clamped between the longitudinal walls but can be released for removal and replacement by movement of at least one longitudinal wall. The transverse walls are also clamped to the supporting frame by releasable means operable from the top of the mold so that they may be removed and replaced without removal of the entire mold.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
99 words
A plate mold for continuous casting, comprising a supporting frame, longitudinal and transverse cooled walls supported on said frame and defining the mold cavity, means for moving at least one of said longitudinal walls to clamp the transverse walls therebetween, means for mounting said transverse walls for sliding movement in vertical direction on said supporting frame during insertion between or withdrawal from between said longitudinal walls, means to clamp said transverse walls to said supporting frame, and means operable from the top of the mold to release said clamping means to permit insertion or withdrawal of said transverse walls.
Claim 2
Dependent Claim
99 words
A plate mold for continuous casting, comprising a supporting frame, longitudinal and transverse cooled walls supported on said frame and defining the mold cavity, means for moving at least one of said longitudinal walls to clamp the transverse walls therebetween, means for mounting said transverse walls for sliding movement in vertical direction on said supporting frame during insertion between or withdrawal from between said longitudinal walls, means to clamp said transverse walls to said supporting frame, and means operable from the top of the mold to release said clamping means to permit insertion or withdrawal of said transverse walls.
Claim 3
Dependent Claim
43 words
A plate mold according to claim 1, in which said guide means comprises a T-shaped guideway in each transverse wall extending substantially parallel to the casting axis, a sliding bar in said guideway and a limit stop at the bottom of said guideway.
Claim 4
Dependent Claim
34 words
A plate mold according to claim 2, in which said clamping means includes compression springs and studs mounted on said sliding bar, and a screw spindle with tapered shoulders adapted to engage said studs.
Claim 5
Dependent Claim
27 words
A plate mold according to claim 1, in which said clamping means couples the inlet and outlet pipes for the cooling water automatically to the transverse wall.
Claim 6
Dependent Claim
23 words
A plate mold according to claim 1, in which said transverse walls have different degrees of taper in respect to the casting direction.
Claim 7
Dependent Claim
23 words
A plate mold according to claim 1, in which said transverse walls are suspended from yokes which rest movably on said supporting frame.
Claim 8
Dependent Claim
21 words
A plate mold according to claim 6, in which the cooling water is conducted tO the transverse walls through said yokes.
