Abstract
Abstract An automatic controlling device for continuous casting molds, comprising moving means linked, respectively, to the opposing short sides of the mold for continuous casting and an electric actuator means linked to said moving means. There is further provided a short side position setting means, a detector linked to said electric actuator means in order to produce a deviation signal based on the deviation between the setting signal and the short side position of the short side position setting means, and a sequence control means which controls the electric actuator means for the purpose of moving the right and left short sides alternatingly to the set position based on said deviation signal.
