总第165期新疆钢铁2023年第1期八钢H型钢“H-H”轧制法的研究及应用实践李强,宋维兆(新疆八一钢铁股份有限公司轧钢厂,新疆乌鲁木齐830022)摘要:八钢小型H型钢厂采用H型钢“X-X”轧制法的工艺布置,此轧制法对万能轧机的装备精度要求较高,在万能轧机侧压辊系磨损严重又修复精度无法满足时会造成轧件腿部金属切偏,出现H型钢成品腹板偏心,影响用户的使用,且此缺陷的调整难度大,常规调整手段很难快速见效,只有更换维修过的轧机才能恢复产品质量。针对此问题研究热轧H型钢“H-H”轧制法,主要目的是降低H型钢轧制过程中对万能轧机的高精度要求,降低生产过程中轧机调整难度,稳定生产和产品质量。八钢公司小型H型钢厂在两年多的实际应用中不断的优化完善,形成了成熟的“H-H”轧制法,目前已实现工字钢和H型钢的生产应用全覆盖。关键词:H型钢;“H-H”轧制法;腹板偏心;万能轧机中图分类号:TG335.1文献标识码:B文章编号:1672-4224(2023)01-0042-04ResearchandApplicationof“H-H”RollingMethodforH-sectionSteelinBayiIronLIQiang,SONGWei-zhao(RollingMill,XinjiangBayiIron&SteelCo.,Ltd.)Abstract:TheprocesslayoutofH-beam“X-X”rollingmethodisadoptedinthesmallH-beammillofBagang.Thisrollingmethodrequireshighequipmentaccuracyoftheuniversalrollingmill.Whenthesidepressurerollsystemoftheuniversalrollingmillisseriouslywornandtherepairaccuracycannotbemet,themetalatthelegoftherolledpiecewillbecutoff,resultingintheeccentricityofthefinishedH-beamweb,whichaffectstheuseofusers.Moreover,theadjustmentofthisdefectisdifficult,andtheconventionaladjustmentmethodsaredifficulttoachievequickresults,Onlybyreplacingtherepairedmillcantheproductqualityberestored.Inviewofthisproblem,the“H-H”rollingmethodforhotrolledH-beamisstudied.ThemainpurposeistoreducethehighprecisionrequirementsforuniversalrollingmillintheH-beamrollingprocess,reducethedifficultyofrollingmilladjustmentintheproductionprocess,andstabilizetheproductionandproductquality.ThesmallH-shapedsteelplantofBagangCompanyhasbeencontinuouslyoptimizedandimprovedinmorethantwoyearsofpracticalapplication,formingamature“H-H”rollingmethod.Atpresent,theproductionandapplicationofI-shapedste...
