CONTINUOUS CASTING MOLD FOR METALS

摘要

An open type casting mold suitably used for continuously casting metals having a large temperature difference between the melting point and the solidifying point thereof, comprises a water-cooling jacket, a 1st stage die portion of other refractory material than graphite inserted in the mold at the inlet portion, said refractory material having a lubricating action with slight abrasion, and a 2nd stage die portion of graphite inserted in the mold at the outlet portion, said 1st stage die portion extending over the back end of the water-cooling jacket into a pouring basin side in a definite length. An even better result is obtained by covering the outer surface of the extended portion of the 1st stage die portion with a fixing member of a refractory material, attaching the fixing member of refractory material to the 1st stage die portion by means of a metallic protecting member, and attaching the metallic protecting member to the watercooling jacket.
