1.轧制过程中,冷床作业人员严禁上冷床,不准在辊道、齿条上行走。2.生产中出现乱床等事故,必须等停轧以后进行处理清出。3.冷床取样要使用专用工具进行取样。4.作业中应注意观察周围的情况,无关人员严禁进入大冷床的***区域。5.因乱床等事故造成的热废品,当班必须清出,确保冷床周围的环境整洁。1.intheprocessofrolling,coolingbedworkersstrictlyonbed,dontwalkontherollerrack.2.intheproductionofrandombeds,suchasaccidents,mustwaitafterthestoprollingprocesstoclearout.3.bedtouseaspecialtoolforsamplingsampling.Shouldobservethesituationaround4.operati,unrelatedpersnondangerousregioninthecoldbed.Wasteheat5.bedbecauseofchaoscausedbytheaccident,thedutymustbeclear,toensurethesurroundingenvironmentcleanbed。二小型作业区型材改造试生产过程中,通过冷床裙板自重式防止角钢倾翻装置的设计及应用,在小角钢的收集过程中,省去了在移钢小车处人工将角钢翻正操作,压缩了了冷床输出的时间,有效防止因角钢倾翻而影响钢材的输出节奏,实现了冷床正常稳定的下钢。Two***allworkareaprofiletransformationproductionprocess,preventtheinclinationangleofdesignandapplicationofdoublebedaprondevicebygr***ity,intheprocessofcollecting***allangle,eliminatingtheneedformovingsteeltrolleyartificialanglerightingoperation,theoutputofthecompressedcoolingbedtime,effectivelypreventtiltingangleandeffectofoutputrhythmofsteel,thesteelcoolingbedundernormalandstable.轧件在冷床冷却过程中由于冷却水不能均匀分布在型钢表面,头部冷却速度较快,弯曲,形成浴盆状,使腹板上的积水不能流出,导致上表面收缩率明显大于型钢下表面,产生上弯。为消除不均匀变形,首先应该使2辊压下量足够大,满足型钢塑变要求。消除型钢原有变形,达到统一的变形的目的。Rollinginbedcoolingprocessduetothecoolingwatercannotbeuniformlydistributedonthesurfaceofsteel,theheadofthefastcoolingrate,thefirstbendformingtubshaped,makewebwatercannotflow,resultinginthesurfaceshrinkageratewassignificantlyhigherthanthatofthesteelsurface,duetobending.Inordertoeliminatetheunevendeformation,firstofall,the2rollershouldbelargeenoughtomeettherequirementofthetypeofsteelplasticchange.Theoriginaldeformationofthesteelhasreachedthegoalofuniformdeformation.明确轴向位置,加大矫直压力。不要单独打8辊轴向,调整侧弯时应以每相临的3个辊为一个调整单元,保证矫直稳定性。Shouldobservethesituationaround4。侧壁斜度的处理措施是经常注意检查各辊轴向位置,窜动情况。注意在不同间隙情况下,矫直力的选取。对H2与H3的测量做到每批抽查,以做到及时调整。Theaxialisclearlydefinedandthestraighteningpressureisincreased.Donotplaythe8rollaxisalone.Whenadjustingthesidebend,3rollsperphaseshouldbeusedasanadjustmentunittoensurethestraighteningstability.Thetreatmentofsidewallslopeistochecktheaxialandmovementofeachroll.Payattentiontotheselectionofmaximumstraighteningforceunderdifferentclearanceconditi.ThemeasurementofH2andH3isdoneineachbatch,soastoadjustitintime.)
