Umbhobho wentsimbi ongenamthungo wenziwa ngaphandle kokuwelda ngeendlela zokusebenza ezishushu ezifana nokuqengqeleka okushushu okunezimbobo. Ukuba kuyimfuneko, umbhobho oshushu ungasetyenziswa ngakumbi ukubanda ukuya kwimo, ubungakanani kunye nokusebenza okufunekayo. Okwangoku, umbhobho wentsimbi ongenamthungo ngowona mbhobho usetyenziswa kakhulu kwiiyunithi zemveliso ye-petrochemical.

Udidi lwezinto: 20G, njl.

Ububanzi besicelo: i-medium eshushu kakhulu yomphunga yebhoyila yoxinzelelo oluphezulu

Uhlolo: Uhlalutyo lokwakheka kweekhemikhali, uvavanyo loxinzelelo, uvavanyo lokuthamba kunye novavanyo loxinzelelo lwamanzi kufuneka lwenziwe kumbhobho wentsimbi osetyenziselwa ukuthuthwa kolwelo ngokubanzi.

GB5310, GB6479, GB9948Kufuneka kuvavanywe iintlobo ezintathu zombhobho wentsimbi oqhelekileyo, ukongeza kwityhubhu yokuthutha ulwelo, kodwa kufuneka kwenziwe uvavanyo lokutsha kunye novavanyo lokuchaphazela; Iimfuno zokuhlolwa kokuveliswa kwezi ntlobo zintathu zombhobho wentsimbi zingqongqo kakhulu.

GB6479umgangatho ukwanika iimfuno ezikhethekileyo zokuqina kwefuthe eliphantsi lobushushu bezinto.

Umbhobho wentsimbi oqhelekileyo we-GB3087, ukongeza kwiimfuno zovavanyo oluqhelekileyo lombhobho wentsimbi yokuthutha ulwelo, kodwa ikwafuna uvavanyo lokugoba olubandayo.

Umbhobho wentsimbi oqhelekileyo we-GB/T8163, ukongeza kwiimfuno zovavanyo oluqhelekileyo lombhobho wentsimbi yokuthutha ulwelo, ngokweemfuno zesivumelwano sokwenza uvavanyo lokuvutha kunye novavanyo lokugoba okubandayo. Iimfuno zokwenziwa kwezi ntlobo zimbini zemibhobho azingqongqo njengezo zeentlobo ezintathu zokuqala.

Ukwenziwa: I-GB/T/8163 kunye ne-GB3087 ipayipi yentsimbi eqhelekileyo isebenzisa i-open furnace okanye i-converter smelting, ukungcola kwayo kunye neziphene zangaphakathi zingaphezulu kakhulu.

GB9948ukunyibilikisa i-furnace yombane. Uninzi longezwa kwinkqubo yokucocwa kwe-furnace ngezithako ezimbalwa kunye neziphene zangaphakathi.

GB6479kwayeGB5310imigangatho ngokwayo ichaza iimfuno zokucocwa ngaphandle kwesithando somlilo, kunye nokungcola okuncinci kunye neziphene zangaphakathi kunye nomgangatho ophezulu wezinto.

Le migangatho ilandelayo yemibhobho yentsimbi yenziwe ngokomgangatho ukusuka kwesezantsi ukuya kwephezulu:

GB/T8163＜GB3087＜GB9948＜GB5310＜GB6479

Ukukhetha: phantsi kweemeko eziqhelekileyo, umbhobho wentsimbi oqhelekileyo we-GB/T8163 ufanelekile kuyilo lobushushu obungaphantsi kwama-350℃, uxinzelelo lungaphantsi kwe-10.0mpa yeemveliso zeoyile, ioyile negesi kunye neemeko zoluntu eziphakathi;

Kwimveliso yeoyile, ioyile kunye negesi ephakathi, xa ubushushu boyilo bungaphezulu kwama-350℃ okanye uxinzelelo lungaphezulu kwe-10.0mpa, kufanelekile ukukhethaGB9948 or GB6479umbhobho wentsimbi oqhelekileyo;

GB9948 or GB6479umgangatho kufuneka usetyenziswe nakwiipayipi ezisebenza kufutshane ne-hydrogen okanye kwiindawo ezisengozini yokugqwala.

Ubushushu obuphantsi ngokubanzi (ngaphantsi kwe -20℃) kusetyenziswa umbhobho wentsimbi yekhabhoni kufuneka kusetyenzisweGB6479umgangatho, kuphela ucacisa iimfuno zokuqina kwefuthe eliphantsi lezinto ezisetyenziswayo.

GB3087 kunyeGB5310imigangatho imiselwe ngokukodwa imigangatho yemibhobho yentsimbi yebhoyila. "Imigaqo yokujonga ukhuseleko lwebhoyila" igxininise ukuba zonke izinto ezidityaniswe nemibhobho yebhoyila zezolawulo, ukusetyenziswa kwezinto kunye nomgangatho kufuneka kuhambelane nemithetho yokhuseleko lwebhoyila, ngoko ke, ibhoyila, isikhululo samandla, isixhobo sokuvelisa ukufudumeza kunye ne-petrochemical esisetyenziswa kumbhobho womphunga kawonkewonke kufuneka sisetyenziswe (ngumboneleli wenkqubo) GB3087 okanye umgangatho oqhelekileyo.GB5310.

Kubalulekile ukuqaphela ukuba umgangatho wemigangatho emihle yemibhobho yentsimbi, amaxabiso eepayipi zentsimbi aphezulu kakhulu, njengakwiGB9948ixabiso lezinto ze-GB8163 liphantse libe yi-1/5, ngoko ke, ekukhetheni imigangatho yezinto zepayipi yentsimbi, kufuneka ziqwalaselwe ngokwemiqathango yokusetyenziswa, zombini ezithembekileyo nezinoqoqosho. Kufuneka kuqatshelwe ukuba iityhubhu zentsimbi ngokuhambelana ne-GB/T20801 kunye ne-TSGD0001, i-GB3087 kunye ne-GB8163 aziyi kusetyenziswa kwipayipi ye-GC1 (ngaphandle kokuba nganye nganye i-ultrasonic, umgangatho ongaphantsi kwe-L2.5, ungasetyenziswa kwipayipi ye-GC1(1) uxinzelelo olungaphantsi kwe-4.0Mpa).

(2) Umbhobho wentsimbi engenamthungo wentsimbi ethambileyo ene-alloy ephantsi

Kwizakhiwo zemveliso ye-petrochemical, imigangatho yemibhobho yentsimbi engenamthungo esetyenziswa rhoqo yentsimbi ye-chromium-molybdenum kunye nentsimbi ye-chromium-molybdenum vanadium isetyenziswa kakhulu.

GB9948 “Umbhobho wentsimbi ongenamthungo wokuqhekeka kwepetroliyam“

GB6479 “Umbhobho wesinyithi ongenamthungo oxinzelelweyo ophezulu wezixhobo zesichumiso“

GB/T5310 “Iityhubhu zentsimbi ezingenamthungo zeebhoyila ezixineneyo“

GB9948iqulethe amanqanaba entsimbi ye-chromium molybdenum: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo njalo njalo.

GB6479iqulethe i-chromium molybdenum steel grade: 12CrMo, 15CrMo, 1Cr5Mo njalo njalo.

GB/T5310iqulethe intsimbi ye-chromium-molybdenum kunye ne-chromium-molybdenum vanadium steel material grades: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, njl.njl.

Phakathi kwabo,GB9948isetyenziswa kakhulu.
