A 650mm wide caster of Unequal Diameter Twin-Rolls type was installed at Sagamihara Works in 1987. More than 300 heats have since been cast. Now we have succeeded to cast more than 4 ton of molten metal and to produce coils which have enough quality to be cold rolled. These coiles were tested its mechanical propaties after cold rolling by Sendzimir mill. And it is confirmed that these strip have almost the same properties of the coils produced by conventional process. A 1000mm wide caster installed at Krupp Stahl started casting at February and we have already succeeded to produce more than 200m long strips in this March.
