Emva kokutshekisha ukunyathela ukuqhelaniswa kwi-rolling mill kunye nokurekhoda, khetha i-roll ekhethekileyo yokuthwala irekhodi yesiphumo sokugcinwa kwekhadi lerekhodi ukurekhoda inombolo yokuhlala, inombolo ye-roll, inombolo yefreyimu, i-bearing orientation kwi-rolling mill, i-bearing area of ​​outer ring, tonnage of rolled products, ukuthwala iiyure zokusebenza kunye nezinye iinkcukacha.Ikhadi kufuneka ligcinwe lihlaziyiweyo kwaye lifikeleleke ngokulula kubasebenzi bokulungisa.Umthwalo wedatha yokulinganisa imithwalo kunye nezinye iinkcukacha zokuvavanya kwindawo engenanto ephantsi kwekhadi lerekhodi.

1.Ukuthwala ukucoca.

Kwinkqubo yokucoca i-bearing, yonke i-ejenti yokuchithwa, amanzi kunye ne-residual smoothing agent kufuneka isuswe, kunye nayo nayiphi na enye into engcolileyo eya kuba yinto enzima yokugqoka. indlela kunye ne-arhente yokucoca ekhethiweyo yokucoca iibheringi zinqunywe.Iibheringi ezincinci okanye iibheringi ezimbalwa zingasetyenziselwa ioli, ioli yamaminerali okanye ezinye i-solvents zorhwebo.Iibheringi ezinkulu okanye i-multi-volume bearings, ioli engathathi hlangothi ingasetyenziselwa ukucoca kwigumbi lokucoca, kunye ne-viscosity ye-22cSt (okanye i-100%; 100SUS) kwi-40% yeoli engathathi hlangothi.

2.Jonga ukuthwala, kuquka ukujonga imbonakalo kunye nokulungiswa okuncinci.

Kwindandatho yangaphakathi ye-roller enokususwa okanye imbonakalo ye-roller, ukuba i-spalling encinci okanye i-epidermal crack ifunyenwe, i-metal peeling igaywe ngomatshini wokusila ngokuqhelekileyo, kunye nomphetho ophuculweyo we-peeling surface.Ukugqoka iimpahla kufuneka kuhlolwe rhoqo, kunye nokugqoka ukuthwala inokuhlolwa ngokulinganisa i-bearing clearance.Hlola kwaye ulungise isihlalo sokuthwala njengoko kufuneka, okanye uhlolisise kwaye ulungise intamo ye-roll njengoko kufuneka, kwaye uphinde ubuyisele i-bearing kunye nesihlalo sokuthwala kumqulu.

3.Iibheringi ezithanjiswayo.

Ngenxa yophuhliso olukhawulezayo loshishino lwe-aluminiyam kwilizwe lethu luye lwaveliswa kwaye lwathunyelwa kumazwe amaninzi anamhlanje ezine okanye ezintandathu zokusila zokusila, ilitye lokusila linamandla amakhulu okuqengqeleka kunye nesantya sokuqengqeleka kweempawu eziphakamileyo, iimfuno zefom iseti epheleleyo yokujikeleza kunye nezixhobo iimveliso eziqengqelekayo bugudileyo ipropathi viscosity-ubushushu, oxidation weza, impahla anti-umhlwa, ukumelana abrasion, etc.At ngoku, akukho.I-oyile ye-220 evaliweyo kunye nomthwalo ophakathi isetyenziswa kakhulu njenge-ejenti yokuthwala i-aluminiyam yasekhaya yasekhaya.Ngenxa yeentsilelo zale oyile egudileyo, efana ne-viscosity ephezulu, i-flash point ephezulu, umxholo wesulfure enkulu, umsebenzi ongalunganga wokucoca i-annealing, njl., kumazwe angaphandle, i-WYTOLB220 ithwele ngaphandle kwamabala e-aluminium rolling mill roll yenkampani ye-ESSO EUnited States, Ioyile egudileyo inomsebenzi olungileyo wokuchasana nokunxiba, i-oxidation kunye nomsebenzi ozolileyo, ukucoca okulungileyo kunye nomsebenzi wokucoca, kwaye akukho mveliso ye-aluminiyam yongcoliseko lweoyile.

Isixa esicetyiswayo segrisi yokuthambisa: ubungakanani bokuzaliswa kwegrisi egudileyo, ukuzalisa indawo yokuhlala kunye nokuzala indawo ye-2/3 okanye i-1/3 ifanelekile, ayifanele ibe lula kakhulu.Emva kokulungiswa kunye nokugaya umqulu ngamnye, kucetyiswa inani legrisi. ukuba ibe yi-1/5 yemali yokuqala.Ixesha lokuhlawulwa kwegrisi egudileyo lihambelana nesakhiwo, isantya, ubushushu kunye nokusingqongileyo kokuthwala.Abasebenzisi bangayilungisa ngokwendawo yokusebenza eyiyo kwaye bagcine igrisi ecocekileyo egudileyo ekuthwaleni phantsi kweemeko ezifanelekileyo.
