Claims

1. THE METHOD OF CONTINUOUS CASTING WHICH COMPRISES THE STEPS OF CONTINUOUSLY CASTING MOLTEN METAL INTO A MOLD, COOLING SAID MOLD TO SOLIDIFIED SKIN ENCLOSING A MOLTO FORM A STRAND HAVING A SOLIDIFIED SKIN ENCLOSING A MOLTEN CORE, WITHDRWAING SAID STRAND FROM SAID MOLD IN COMTINUOUS MANNER, COOLING SAID STRAND TO PROGRESSIVELY SOLIDIFY THE MOLTEN METAL IN SAID CORE, MEASURING THE THICKNESS OF THE SOLIDIFEIED SKIN OF THE STRAND ENCLOSING THE MOLTEN CORE AND CONTROLLING THE CASTING PROCESS IN ACCORDANCE WITH SAID MEASUREMENT OF THE SKIN THICKNESS TO MAINTAIN THE SKIN THICKNESS ENCLOSING THE MOLTEN CORE WITH SUFFICIENT MATERIAL TO WITHSTAND WORKING OPERATION ACCORDING TO THE METAL TO BE CAST.
