在轧机设置了上轧辊动态轴向调整。轧机调零后，可以测量和存储上探头到上辊轴及下探头到下辊轴的距离。轧制过程中立辊如失去平衡而引起上辊或下辊的窜动，上辊会与下辊同步调整，从而保证上、下腹板对中并控制腹板和翼缘的尺寸。Thereisadynamicaxialadjustmentoftheupperrollontheuniversalrollingmill.Aftertherollingmilliszero,thedistancebetweentheupperrollshaftandthelowerprobecanbemeasuredandstored.Duringtherollingprocess,iftheneutralrollslosebalance,theupperrollerorthelowerrollwillmove.Theupperrollerwillsynchronizewiththelowerroller,soastoensuretheupperandlowerplatealignmentandthedimensiofwebandflange.短应力线轧机具有如下优点：⑴容易实现负公差轧制，因为轧机的高刚度保证了产品的。⑵可实现轧机左右两个轴承的对称调整，这对于稳定轧制条件，提高作业率，节省检修和更换导卫、横梁时间等具有重要意义。Shortstresslinemillhasthefollowingadvantages:Itiseasytorealizenegativetolerancerollingmill,becauseofthehighrigiditytoensurehighprecisionproducts.Thesymmetricadjustmentcanachieveabouttworollingbearings,thestablerollingcondition,improveoperationefficiency,s***ingmaintenanceandreplacementhasimportantsignificancetoguideandbeamtimeetc.按轧制品种、轧机型式和公称尺寸来命名。“公称尺寸”的原则对型材轧机而言，是以齿轮座人字齿轮节圆直径命名。Itisnamedaccordingtothevarietiesofrolling,thetypeofrollingmillandthenominalsize.TheprincipleofnominalsizeForrollingmills,theyarenamedafterthegearringandthepitchdiameteroftheherringbonegear.四棍轧机的工作辊直径较小，传递轧制力矩，轧延压力由直径较大的支承辊承受。这类设备的主要优点是相对刚度较大，压下量大、轧延力小，可轧制较薄的板材，也包括有可逆和连轧两种。Theworkingrolldiameterofthefourbarmillis***all,andtherollingtorqueistransferred.Therollingpressureisbornebythebackuprollerwithlargerdiameter.Themainadvantagesofthistypeofequipmentarerelativelylargestiffness,largereduction,lowrollingforce,thinrolledsheets,andreversibleandcontinuousrollingtwo.)
