ABSTRACT:
Heat removal in a continuous metal casting machine may now be gauged by new normalized thermal parameters instead of the conventional coolant temperature differential parameter. One new thermal parameter is caster mold heat removal rate per unit length of peripheral mold face. This enables a direct comparison of mold sizes and designs. A second new parameter is mold face specific heat removal as a function of the first new parameter and casting speed. The second new parameter is indicative of strand skin growth without actually measuring skin thickness. Third and fourth new parameters are derived by independently ratioing the first and second new parameters so as to reference to a base mold face with the other mold faces. All of the new thermal parameters may also be used to gauge heat removal from caster spray cooling and roll cooling zones. Instrumentation is provided for computing the new thermal parameters during caster operation.
