CASTING MOLD FOR CONTINUOUS CASTING AND CASTING METHOD BY USING THE MOLD

摘要

PURPOSE:To speedily and stably cast continuously cast billet of small lot or small section while effectively preventing the generation of the drawing mark and to reduce the manufacturing cost. CONSTITUTION:A water cooling casting mold 11 has a straight inner circumferential surface, at whose inner circumferential surface the step is set and a ceramic casting mold 12 is inserted in the above stepped part with shrinkage fitting. And the relation of the heat conductivity (a) and the length of casting mold L1 of the ceramics mold 12 is made to the next integrally in the case that the length of the copper casting mold 11 is L2. If a =0.006 : (-3.05a+0.386) L2=L1=L2, if a0.06:(-0.124a+0.221) L2=L1=L2, here L2=1000 (mm).
