Abstract：Aiming atthe online optimization problem inthe continuous casting cuting process，a multi-objectiveoptimization model basedontheideaofbox problem modeling is proposed.The modelof“5boxesand1section”isconstructed andsolved by sequentialalgoithtoobtaintheoptialcutingshemeoftailbilet.Wenanabnomalityoccursintecystalizer，the“6boxes andlsection”modelisusedforralteoptimiationtoensuretheefectivenessofthecutingsheme.Ifnewabnormalityours againinthecrystalizer，the“6-boxmulti-segment”modelisusedtoadjustheorginalcutingschemetofurtherreducethecuting loss.The above three models provide a new method for online optimization of continuous casting cutting.

0引言

连铸是将钢水变成钢坏的生产过程，具体流程如图1所示，钢水连续地从中间包浇入结晶器，并按一定的速度从结晶器向下拉出进入二冷段，经过二冷段之后形成钢坯，然后按照一定的尺寸要求对钢坏进行切割。（剩余7181字）
