  • Mold or wide cross section for the hot-top vertical continuous casting of metals
    Patent number: 6419004
    Abstract: A mold for hot-top vertical continuous casting of metals includes a feed head (8) made of a thermally insulating refractory material which surmounts a cooled copper crystallizer (9) and is internally aligned with a cooled copper element (14) of the cooled copper crystallizer (9) in order to define a calibrating passage for the cast metal. The copper element (14) is formed by an assembly of plates, some of which, termed “large walls”, are each held against a reinforcing backplate (16) to which it is rigidly fastened by a clamp (22), the shape of which is elongate in the width direction of the large wall and which goes over the top of the large wall and its associated backplate.
