EFFICIENCY OF CONTINUOUS-CASTER-MOLD WALLS WITH CYLINDRICAL AND SLIT-LIKE CHANNELS

摘要

One way of improving the durability of the working walls of continuous-caster molds is to increase the rate at which heat is removed from the melt. New designs of mold walls have been developed for this specific purpose. This article compares the thermal state and temperatures of molds having drilled and slit-type channels for coolant water. An algorithm is developed to design bolts for securing the working slabs of the mold. The algorithm was developed with allowance for the nonuniformity of temperature over the surface of the mold walls and with the assumption that the joints between the walls remains intact during service.
