METHOD FOR MAKING CONTINUOUSLY CAST DEFORMED BILLETS AND APPARATUS FOR PERFORMING THE SAME |
摘要 |
metallurgy. SUBSTANCE: mold includes pair of vertical walls performing reciprocation motion and pair of walls inclined in their upper portion and performing rotation motion. Metal supply is started to non-operating mold when walls of pair of walls inclined in their upper portion are drawn apart by 60-75 degrees. One-piece seed is flat and it is placed under mold along spacing H1 related with height H of vertical lower portion of first pair of walls by relation H1/H=0.25-0.3. EFFECT: less loss of yield, enhanced quality of billet surface and inner structure of billets. 2 cl, 1 ex, 2 dwg
