1. Umhlwa rhoqo kunye nokukhuselwa kwe-anti-corrosion
Ngokuqhelekileyo, isakhiwo sensimbi yiminyaka eyi-5O-70 kwixesha loyilo kunye nokusetyenziswa.Ngethuba lokusetyenziswa kwesakhiwo sensimbi, amathuba omonakalo ngenxa yomthwalo omkhulu amancinci.Uninzi lomonakalo wesakhiwo sentsimbi ubangelwa kukuncitshiswa kwee-mechanics zesakhiwo kunye neempawu ezibonakalayo ezibangelwa ngumhlwa."I-Snueling of Steel Structure Design" ineemfuno ezithile ze-anticorrosion yesakhiwo sensimbi esetyenziswe ngaphezu kweminyaka engama-25.Ngoko ke, kuyimfuneko ukuhlangabezana neemfuno zesakhiwo sensimbi ngaphandle kwesakhiwo sensimbi.Ngokuqhelekileyo, isakhiwo sensimbi sithatha iminyaka eyi-3 ukugcina ukugcinwa (ukucoca uthuli kwisakhiwo sensimbi, i-rust, kunye nolunye ukungcola ngaphambi kokuxubha i-coating).Iindidi kunye neenkcukacha zepeyinti kufuneka zifanane neengubo zangaphambili, ngaphandle koko iingubo ezimbini aziyi kuhambelana ziya kuzisa umonakalo omkhulu, kwaye abasebenzisi kufuneka bagcinwe kakuhle kwaye bagcinwe ngendlela ecwangcisiweyo.
Ukuthintela ukugqwala kwesakhiwo sensimbi: Kwixesha elizayo lokugcinwa nokugcinwa, indlela yokukhusela i-non-metal coating isetyenziswa ngokuqhelekileyo.Ikhuselwe ngeengubo kunye neplastiki phezu kwendawo yecandelo, ukwenzela ukuba ingadibanisi neendaba ezijikelezayo eziphazamisayo ukufezekisa injongo ye-anticorrosion.Le ndlela inemiphumo emihle, amaxabiso aphantsi, kunye neentlobo ezininzi zeengubo.Ifumaneka kuluhlu olubanzi lokukhetha, ukusetyenziswa okunamandla, kunye nezithintelo kwimilo kunye nobukhulu becandelo.Icandelo lirhoxisiwe kwaye kulula ukulisebenzisa.Unako kwakhona ukunika amacandelo imbonakalo entle.
2. Ukhuseleko lonyango lomlilo rhoqo
Ukumelana nokushisa kwentsimbi kubi, kwaye iipropati ezininzi zitshintsha ngobushushu.Xa iqondo lokushisa lifikelela kwi-430-540 ° C, indawo yokuvunwa, amandla okuqina kunye ne-elastic modulus yentsimbi iya kuhla ngokukhawuleza kwaye ilahlekelwe amandla okuthwala.Kuyimfuneko ukusebenzisa izinto ezichasayo ukugcina isakhiwo sentsimbi.Ayizange iphathwe ngaphambili ngeengubo ezingatshiyo okanye ipeyinti engatshiyo.Umthamo we-refractory wesakhiwo uxhomekeke ekuchaseni umlilo wecandelo lokwakha.Xa umlilo uvela, umthamo wayo wokuthwala kufuneka ukwazi ukuqhubeka ixesha elithile, ukwenzela ukuba abantu baphume ngokukhuselekileyo, izixhobo zokuhlangula kunye nokucima umlilo.
Amanyathelo okuthintela umlilo: ngoko icandelo lensimbi eliveziweyo lokuxubha iingubo zokukhusela umlilo, iimfuno ezikhethekileyo zezi: ixesha eliphikisayo lentsimbi yentsimbi yi-1.5h, kunye nexesha eliphikisayo lekholomu yensimbi yi-2.5h, eyenza ukuba ihlangabezane neemfuno yeenkcukacha zezoyilo.
3. Ukubeka iliso rhoqo kunye nokugcinwa kwenguqu
Ukutshatyalaliswa kwe-rust ye-steel structure akubonakali nje njengento encinci yecandelo elisebenzayo lecandelo, kodwa kunye "nomgodi wokugqwala" owenziwe ngumhlaba wecandelo.Owangaphambili wanciphisa umthamo wokulayisha wecandelo, okwabangela ukuba umthamo wokuthwala jikelele wesakhiwo sensimbi unciphise, kwaye isakhiwo sentsimbi enqabileyo kunye nentsimbi ekhanyayo yayinzulu kakhulu.Le yokugqibela ibangela "uxinzelelo lokuxininisa" into yesakhiwo sensimbi.Xa isakhiwo sensimbi singenzeka, isakhiwo sensimbi sinokuvela ngokukhawuleza.Akukho zimpawu ze-deformation xa le nto isenzeka, kwaye akulula ukubhaqa kunye nokuthintela kwangaphambili.Ukuza kuthi ga ngoku, uxinzelelo, ukuguqulwa kunye nokubeka iliso lokuqhekeka kwezakhiwo zetsimbi kunye namacandelo amakhulu kubaluleke kakhulu.
Ukujongwa kwe-Deformation: Ukuba isakhiwo sensimbi sinokuguqulwa okugqithisileyo ngexesha lokusetyenziswa, kubonisa ukuba umthamo wokuthwala okanye ukuzinza kwesakhiwo sensimbi asikwazi ukuhlangabezana neemfuno zokusetyenziswa.Ngeli xesha, umnini kufuneka aqhotyoshelwe ngokwaneleyo ukuba aququzelele ngokukhawuleza abantu abafanelekileyo kwishishini ukuhlalutya imbangela yokuguqulwa.Isicwangciso solawulo sicetywa kwaye siphunyezwe ngokukhawuleza ukukhusela umonakalo omkhulu kubunjineli besakhiwo sensimbi.
4. Ukuhlolwa rhoqo kunye nokugcinwa kwezinye izifo
Xa usenza ulawulo lwemihla ngemihla kunye nokugcinwa kobunjineli besakhiwo sentsimbi, ngaphezu kokunikela ingqalelo ekuhlolweni kwesifo se-rust, kufuneka uhlawule ingqalelo kule miba ilandelayo:
(1) Ingaba ukudityaniswa kwee-welds, iibholiti, iirivethi, njl.
(2) Ingaba amacandelo afana nepali nganye, isisu, ibhodi yokudibanisa, njl.njl. i-deformation yendawo kakhulu kwaye ingaba kukho nawuphi na umonakalo.
(3) Ingaba i-deformation yonke yesakhiwo ayiqhelekanga kwaye ingaba kukho uluhlu oluqhelekileyo lokuguqulwa.
Ukuhlolwa nokugcinwa kokulawulwa kwansuku zonke: Ukuze ufumane izifo ezikhankanywe ngasentla kunye neziganeko ezingaqhelekanga kwaye ugweme imiphumo emibi, umnini kufuneka enze uhlolo oluqhelekileyo lwesakhiwo sensimbi rhoqo.Ngelixa ubamba ukuphuhliswa kwayo kunye notshintsho, imbangela yokubunjwa kwesifo kunye neziganeko ezingaqhelekanga kufuneka zifumaneke.Ukuba kuyimfuneko, ngohlalutyo oluchanekileyo lwethiyori, lufumaneka kwimpembelelo yamandla, ukuqina, kunye nokuzinza kwesakhiwo sensimbi.
