| Abstract: | The reasons of breakout by sticking of 45# steel slab are analyzed systematically by researching the solidifying characteristics of low liquid-phrase line temperature, the wide liquid-solid phrase zone and small shell-shrinkage quantity of 45# steel. Then some measures are put forward from mould powder, mould oscillation, cooling water and process operation, etc. and carried on, the practice shows that the 45# steel production in No.1 steel-making plant of Jigang is free of breakout by sticking and stable. |
