A continuous casting mold includes two long side walls which are arranged opposite each other on support frames. For the purpose of adjusting the width of the mold short, side walls which can be moved toward each other are tightly clamped between the long side walls. Mechanical clamping elements which are in connection with hydraulic piston-cylinder units are provided for chucking the short side walls between the long side walls. The support frames with the long side walls are arranged in the continuous casting mold and are connected to the clamping elements in such a way that they can be moved toward each other as well as apart from each other.

Why it's free to use
- Filed September 7, 1990 and granted January 23, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 7, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 7, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
