2023年2月第31卷第1期河南冶金HENANMETALLURGYFeb.2023Vol.31No.1100t钢包扩容设计与实践(TangShanHeBei)张文祥武晓阳李超柳晓辉张朝发魏军（河钢股份有限公司唐山分公司）摘要唐钢长材事业部转炉设计为100t,为满足后期生产要求，转炉出钢量可提高到125t。为适应此生产工艺变化，需对100t钢包进行优化设计，首先根据容积计算耐材厚度；其次进行耐材设计，降低刚玉自流料浇筑厚度、去掉安全衬砖、减少保温板厚度等；最后调整砌筑工艺，在满足精炼净空要求的条件下，舍去包沿砖，采用渣线砖和包壁砖的修砌方法。经计算，设计后的钢包可满足盛装125t钢水的需求，更好地匹配提产后转炉一精炼－连铸机的生产模式，提高了生产率和钢水收得率，最终达到提高炼钢产能，降低炼钢成本的目的，实现了生产的高效稳定运行。关键词钢包扩容设计实践DESIGNANDAPPLICATIONPRACTICEOF10OtLADLECAPACITYEXPANDINGZhangWenxiangWuXiaoyangLiChaoLiuXiaohuiZhangChaofangWeiJunABSTRACTTheconverterdesignofLongMaterialBusinessDivisionofTanggangis100t.Inordertomeettherequirementsoflaterproduction,thetappingcapacityoftheconvertercanbeincreasedto125t.Inordertoadapttothisproductionprocesschange,itisnecessarytooptimizethedesignandimprovementof100tladle.Firstly,thethicknessofrefractorymaterialiscalculatedaccordingtothecapacity;secondly,therefractorymaterialisdesignedtoreducethepouringthicknessofcorundumselfflowingmaterial,removethesafetyliningbrick,andreducethethicknessofinsulationboard;finally,themasonryprocessisadjusted.,undertheconditionofmeetingtherequirementsofrefiningclearance,thebrickalongtheedgeisdiscardedandtherepairmethodofslaglinebrickandwallbrickisadopted.Aftercalculation,theladlecanmeetthedemandofholding125tmoltensteel,bettermatchtheproductionmodeofconverterrefiningcontinuouscastingmachine,theproductivityandtheyieldofmoltensteelareimproved,finallythegoalofimprovingthesteel-makingcapacityandreducingthesteel-makingcostareachieved,andtheefficientandstableoperationofproductionisrealized.KEYWORDSLadleCapacityExpansionDesignPractice0前言为满足生产需求，转炉后期有效容积增大后可以增加出钢量，但是转炉增产受现有钢包容量的限制，钢包装人量过大容易出现精炼炉溢渣现...
