I-China Umgangatho ophakamileyo we-carbon structural steel, i-alloy structural iron kunye nentsimbi engapheliyo yokumelana nobushushu obuphezulu boxinzelelo oluphezulu lombhobho webhoyila yomphunga phantsi koxinzelelo oluphezulu kunye noxinzelelo olungaphezulu koMvelisi kunye noMboneleli

Umgangatho ophezulu wekhabhoni yolwakhiwo lwentsimbi, ingxubevange yentsimbi yolwakhiwo kunye nentsimbi ekwazi ukumelana nobushushu obungatyiwayo.

Umgangatho ophezulu wekhabhoni yolwakhiwo lwentsimbi, ingxubevange yentsimbi yolwakhiwo kunye nentsimbi exhathisayo ubushushu obungenaxinzelelo oluphezulu umbhobho ongenamthungo webhoyila yomphunga phantsi koxinzelelo oluphezulu nangaphezulu koxinzelelo Umfanekiso

Inkcazelo emfutshane:

Indlela yokuvelisa:

(1) Jikelele GB9948 ingenamthungo umbhobho iqondo lobushushu intsimbi ingaphantsi kwama-450 ℃, umbhobho yasekhaya ikakhulu yenziwe no. I-10, i-20 ye-carbon edityanisiweyo yentsimbi eshushu yaqengqeleka umbhobho okanye umbhobho ozotyiweyo obandayo.

I-②GB9948 ipayipi yensimbi engenamthungo isoloko isetyenziselwa ubushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, umbhobho phantsi kwesenzo segesi ephezulu yokushisa kunye nomphunga wamanzi, i-oxidation kunye ne-corrosion iya kwenzeka.Umbhobho wensimbi kufuneka ube namandla ahlala ixesha elide, ukuxhathisa kwe-corrosion oxidation ephezulu. kunye nokuzinza okulungileyo kwe-microstructure.

(2) sebenzisa:

(1) Ngokubanzi i-GB9948 umbhobho wentsimbi ongenamthungo usetyenziswa ikakhulu ukwenza umbhobho wodonga olupholileyo ngamanzi, umbhobho wamanzi abilayo, umbhobho womphunga oshushu kakhulu, umbhobho webhoyila oshushu kakhulu, umbhobho womsi omkhulu kunye omncinci kunye nombhobho wezitena we-arch.

②GB9948 ityhubhu yentsimbi engenamthungo isetyenziswa ikakhulu ukwenza ityhubhu yokufudumeza, ityhubhu yokufudumeza, umbhobho, umbhobho ophambili womphunga njalo njalo kuxinzelelo oluphezulu kunye nebhoyila yoxinzelelo oluphezulu.

I-GB9948 ityhubhu yebhoyila engenamthungo ngokwentsebenzo yobushushu obuphezulu yahlulahlulwe kwityhubhu yebhoyila ngokubanzi kunye netyhubhu yebhoyila yoxinzelelo oluphezulu.Ukuba ityhubhu yebhoyila ngokubanzi okanye ityhubhu yebhoyila yoxinzelelo oluphezulu inokwahlulwa ibe yityhubhu yentsimbi eyahlukeneyo ngokweemfuno ezahlukeneyo zokusetyenziswa kwayo.

Iinkcukacha kunye nomgangatho wenkangeleko

(1)GB3087-2008 "Ipayipi yentsimbi engenamthungo kwibhoyila yoxinzelelo oluphantsi kunye oluphakathi" izibonelelo.Iinkcukacha zeetyhubhu zentsimbi kwiibhoyila ezahlukeneyo zesakhiwo, i-diameter 10 ~ 426mm, iindidi ezingama-43 zizonke.Kukho iintlobo ezingama-29 zodonga ukusuka kwi-1.5 mm ukuya kwi-26mm .Nangona kunjalo, i-diameter yangaphandle kunye nobukhulu bodonga lombhobho womphunga oshushu kakhulu, umbhobho womsi omkhulu, umbhobho omncinci womsi kunye nombhobho we-arch wezitena osetyenziswa kwibhoyila ye-locomotive zichazwe ngenye indlela.

(2)GB5310-2008 "Ithubhu yentsimbi engenamthungo yeBoiler yoxinzelelo oluphezulu" umbhobho oshushu waqengqeleka ububanzi 22 ~ 530mm, ubukhulu bodonga 20 ~ 70mm.I-Cold draw (ebandayo iqengqeleke) ubukhulu betyhubhu 10 ~ 108mm, ubukhulu bodonga 2.0 ~ 13.0mm.

(3) GB3087-2008 "ityhubhu yentsimbi engenamthungo kwibhoyila ephantsi kunye nephakathi" kunye ne-GB5310-2008 "ityhubhu yensimbi engenamthungo kwibhoyila yoxinzelelo oluphezulu" izibonelelo.Umgangatho wokubonakala: ukuqhekeka, ukugoqa, ukuqengqeleka, ukukrala, ukwahlula kunye nemibimbi akuvumelekanga ukuba kuqhubeke. umphezulu wangaphakathi nangaphandle wombhobho wentsimbi.Ezi ziphene kufuneka zipheliswe ngokupheleleyo.Ubunzulu bococeko abuyi kudlula ukutenxa okungalunganga kobukhulu bodonga lwegama, kwaye ubukhulu bodonga lokwenene kwindawo yokucima abuyi kuba ngaphantsi kobuncinane obuvumelekileyo bodonga. .

Imfuneko yoVavanyo

Uvavanyo lwe-hydraulic
Uvavanyo lwe-hydraulic luya kwenziwa kwimibhobho yentsimbi nganye nganye. Uxinzelelo oluphezulu lovavanyo luyi-20 MPa. Ngaphantsi koxinzelelo lovavanyo, ixesha lokuzinza aliyi kuba ngaphantsi kwe-10 s, kwaye ukuvuza kombhobho wensimbi akuvumelekanga.
Uvavanyo lokucaba
Uvavanyo lwe-flattening luya kuqhutywa kumbhobho wentsimbi kunye nobubanzi obungaphandle ngaphezu kwe-22 mm
Uvavanyo lomlilo
Umgangatho ophezulu we-carbon structural steel kunye nemibhobho yentsimbi (ekwazi ukumelana nobushushu) kunye nobubanzi obungaphandle obungekho ngaphezu kwe-76 mm kunye nobukhulu bodonga obungekho ngaphezu kwe-8 mm buya kuxhomekeka kuvavanyo olwandisiweyo. Uvavanyo lokuvutha luya kwenziwa kwiqondo lokushisa. Umyinge wangaphandle wokugqabhuka kwesampulu emva kokuba i-taper ye-core core i-60% ye-flaring iya kuhlangabezana neemfuno zetheyibhile 7. Akukho kuphazamiseka okanye ukuqhekeka kuvunyelwe kwisampuli emva kokuvutha. Ngokweemfuno zomfaki-sicelo kwaye kuphawulwe kwikhontrakthi, i-alloy structural steel ingasetyenziselwa ukwandisa uvavanyo.
Itesta engonakalisiyo
Imibhobho yensimbi iya kuba phantsi kokufumanisa impazamo ye-ultrasonic nganye ngokuhambelana namalungiselelo e-GB / T 5777-2008. Ngokweemfuno zomfaki-sicelo, ezinye iimvavanyo ezingonakalisi zingongezwa emva kokuxoxisana phakathi komthengisi kunye nomceli kwaye ziboniswe kwisivumelwano.
Uvavanyo lwe-Intergranular Corrosion
Uvavanyo lwe-Intergranular corrosion luya kuqhutywa kumbhobho wentsimbi ongenasici (ukumelana nobushushu). Indlela yokuvavanya iya kuhambelana namalungiselelo endlela yaseTshayina E kwi-GB / T 4334-2008, kwaye ukuthambekela kwe-intergranular corrosion akuvumelekanga emva kovavanyo.
Emva kothethathethwano phakathi komthengisi kunye nomenzi, kwaye kuphawulwe kwikhontrakthi, umfaki-sicelo unokubeka ezinye iindlela zovavanyo lomhlwa.
