黑色氧化是INA轴承钢表面化学反应的一种表面处理方法。当零件在大约150摄氏度的工作温度下浸入碱性盐水溶液中时，会形成黑色氧化层。BlackoxidationisasurfacetreatmentmethodofchemicalreactiononthesurfaceofINAbearingsteel.Blackoxidelayerisformedwhenpartsareimmersedinalkalinebrinesolutionatworkingtemperatureofabout150degreesCelsius.黑色氧化物的好处bi须通过单独的应用来判断，但这种处理没有任何危害。它已成功地应用于其余行业难以操作的INA轴承，如造纸机辊、机床和工业通风机。黑色氧化过程涉及许多参数。整个过程包括大约15个不同的浸渍步骤。在许多步骤中，化学成分、浓度、温度、浸渍时间和流体特性都可以调整。ThebenefitsofblackoxideBimustbejudgedbyitsapplicationalone,butthereisnoharminthistreatment.IthasbeensuccessfullyappliedtoINAbearingswhicharedifficulttooperateinotherindustries,suchaspapermillrolls,machinetoolsandindustrialventilators.Blackoxidationprocessinvolvesmanyparameters.Thewholeprocessincludesabout15differentimpregnationsteps.Inmanysteps,chemicalcomposition,concentration,temperature,impregnationtimeandfluidcharacteristicscanbeadjusted.为了达到***佳性能，建议内外环和辊均采用黑色氧化处理。黑色氧化可应用于大型风力机的所有轴承类型。近年来，圆柱滚子轴承和圆锥滚子轴承的到了成功的处理和使用。Inordertoachievethebestperformanceof***,blackoxidationtreatmentisrecommendedforbothinnerandouterringsandrolls.Blackoxidationcanbeappliedtoallbearingtypesoflargewindturbines.Inrecentyears,cylindricalrollerbearingsandtaperedrollerbearingsh***ebeensuccessfullytreatedandused.轴承座上中部和轴承座外侧（朝向辊头）注入的润滑脂不能很好地进入轧机轴承，容易丢失，导致轴承在轧制过程中工作面油质bu良，导致轴承早期失效。Thelubricatinggreaseinjectedintothemiddlepartofthebearingseatandtheoutersideofthebearingseat(towa***therollerhead)cannotentertherollingmillbearingwellandiseasytobelost,resultingingoodoilBuintheworkingfaceofthebearingduringrollingprocess,leadingtoearlyfailureofthebearing.为此，对轴承座油路进行了改进，在INA轴承座内侧（朝向辊体）增加了喷油嘴，提高了注脂效果。轴承润滑良好。大多数轧钢机现在使用润滑脂润滑。由于立磨的结构，使轴承在轧辊转动时使用寿命延长。Forthisreason,theoilcircuitofbearingseatwasimproved,andtheoilinjectorwasaddedtotheinnersideofINAbearingseat(towa***therollbody)toimprovethegreaseinjectioneffect.Thebearingsarewelllubricated.Mostrollingmillsnowusegreaselubrication.Becauseofthestructureoftheverticalmill,theservicelifeofthebearingisprolongedwhentherollrotates.根据主机部件的要求注入规定的润滑脂或润滑剂。Injectthespecifiedgreaseorlubricantaccordingtotherequirementsofthemainengineparts.装配大轴承及轴承与轴、座孔间隙大的产品时，bi须用油浴加热轴承，油浴温度约80℃。Whenassemblinglargebearingsandproductswithlargeclearancebetweenbearingsandaxlesandseatholes,Bimustuseoilbathtoheatbearings,andtheoilbathtemperatureisabout80C.拆卸INA轴承时，bi须使用专用绘图工具。严禁用铁制工具直接敲打轴承。WhendisassemblingINAbearings,Bimustusespecialdrawingtools.Itisstrictlyforbiddentotapbearingsdirectlywithirontools.在装配和拆卸轴承时，应避免滚动部件和保持架受力或变形。Whenassemblinganddisassemblingbearings,forceordeformationofrollingpartsandcagesshouldbe***oided.文章来自：SKF轴承www.wh-Articlefrom:SKFBearingwww.wh-文章来自：INA轴承a-Articlesfrom:INABearinga-文章来自：NSK轴承Articlefrom:NSKBearing***：524085168电话：0510-81207777手机：13311666672/13395185757)
