ABSTRACT:
Metal strip 9 cast directly from the melt onto a cylindrical casting drum 20 is made more uniform in thickness and in structure by making the temperature of the casting surface and, therefore, heat transfer more uniform, thus reducing distortion of the casting surface. This is accomplished by a novel arrangement of helical coolant channels 25 extending below the casting surface 10 and in heat transfer relationship with the casting surface and being at an angle of between about 15.degree. and 75.degree. (and preferably between about 45.degree. and 75.degree.) to the drum axis. At least one coolant inlet 21 and one coolant outlet 22 supply and withdraw coolant to each channel. In one embodiment, inlets (21a, 21b) are alternated on the same side of the shell with outlets (22a and 22b) of adjacent channels so that the cooler regions around inlets and alternated with higher temperature outlet regions to balance the temperature around the surface.
