采用连铸坯直接轧制或连铸坯热装炉,即实现零火或半火成材时,要求连铸坯尺寸要合理,轧制节奏时间与连铸出坯节奏时间应一致,以保证连铸机与轧机生产的协调。目前,我国连铸坯生产表明:小型连铸机虽然可以连铸出50、70mm方和圆坯,但是漏钢率高,而且连铸坯断面愈小,连铸时漏钢率愈高;连铸机生产小断面连铸坯时
The use of continuous casting billet or continuous casting billet hot charging furnace, that is, to achieve zero fire or semi-fire into the timber, the requirements of continuous casting size to be reasonable, rolling rhythm and continuous casting rhythm should be consistent with the time to ensure even Caster and rolling mill production coordination. At present, the production of continuous casting slab in our country shows that although small continuous casting machine can continuously cast 50,70mm square and round billet, but the leakage rate is high, and the smaller the continuous billet cross section, the higher the leakage rate in continuous casting. Caster production of small cross-section billet
