I-JIS G 3455 Imigangatho Elinganayo
Iimveliso zethu ezinxulumeneyo
Ubungakanani Uluhlu
Umbhobho ngaphandle ubukhulu: 10.5-660.4mm (6-650A) (1/8-26B)
A=DN;B=NPS.
Ukuhlelwa kweBanga
I-JIS G 3455 inamabakala amathathu ngokobuncinane bokuqina kombhobho, oko kukuthiSTS370, STS410, kwayeSTS480.
Iinkqubo Zokuvelisa
Imibhobho kufuneka yenziwe ngaphandle komthungo ngentsimbi ebuleweyo.
Ukubunjwa kokugqibela kwahlulwe kwiindidi ezimbini, ezishushu-ezigqityiweyo kwaye zibandayo, kuxhomekeke kububanzi obungaphandle kunye nobukhulu bodonga.
Uphawu lwebakala | Uphawu lwenkqubo yokuvelisa | |
Inkqubo yokwenziwa kwemibhobho | Indlela yokugqiba | |
STS370 STS410 STS480 | Ngaphandle komthungo: S | Igqityiwe ngokushushu: H Kubanda kugqityiwe: C |
Unyango lobushushu
Uphawu lwebakala | Ishushu-igqityiwe umbhobho wentsimbi ongenamthungo | Kubanda-kugqityiwe umbhobho wentsimbi ongenamthungo |
STS370 STS410 | Njengoko yenziwe. Nangona kunjalo, i-annealing yobushushu obuphantsi okanye i-normalizing ingasetyenziswa njengoko kuyimfuneko. | Ubushushu obuphantsi bufakwe okanye buqhelekile |
STS480 | Ubushushu obuphantsi bufakwe okanye buqhelekile |
Unyango lobushushu ngaphandle kwalolo lunikiweyo kwitheyibhile lunokwenziwa ngesivumelwano phakathi komthengi nomvelisi.
Uhlobo lokuphela kombhobho
Imibhobho iya kugqitywa ngeziphelo ezisicaba.
Ukuba isiphelo se-beveled sicacisiwe, i-tapered end shape yemibhobho enobunzima bodonga ≤ 22 mm iya kuhambelana ne-30-35 °, kunye nobubanzi be-bevel bombhobho wentsimbi bukhulu be-2.4mm.
Amacandelo eMichiza ye-JIS G 3455
Uhlalutyo lobushushu luya kuhambelana ne-JIS G 0320. Uhlalutyo lwemveliso luya kuhambelana ne-JIS G 0321.
Amaxabiso ohlalutyo lwe-thermal aya kuhambelana nezi mfuno zilandelayo:
Uphawu lwebakala | C (iKhabhoni) | Si (Silicon) | Mn (Manganese) | P (Phosphorus) | S (Sulfur) |
max | max | max | |||
STS370 | 0.25% | 0.10-0.35% | 0.30-1.10% | 0.35% | 0.35% |
STS410 | 0.30% | 0.10-0.35% | 0.30-1.40% | 0.35% | 0.35% |
STS480 | 0.33% | 0.10-0.35% | 0.30-1.50% | 0.35% | 0.35% |
Amaxabiso ahlalutyiweyo emveliso akufanele ahlangabezane namaxabiso kwitheyibhile kuphela, kodwa uluhlu lonyamezelo lwento nganye kufuneka luhambelane neemfuno zeThebhile 3 ye-JIS G 3021.
IPropati yoomatshini ye-JIS G 3455
Iimfuno jikelele zovavanyo lomatshini ziya kuhambelana nesolotya lesi-7 nelesi-9 le-JIS G 0404. Iindlela zesampulu zovavanyo lomatshini ziya kuhambelana neKlasi A ye-JIS G 0404, iGatya 7.6.
Amandla okuqina, iNqaku lokuZivuza okanye uQinisekiso loQinisekiso, kunye nokwandiswa
Indlela yokuvavanya iya kuhambelana nemigangatho ye-JIS Z 2241.
Kwimibhobho ephantsi kovavanyo lwe-tensile usebenzisa i-specimen ye-12 okanye i-No.
Ukunyanzeliswa kokuchasa
Uvavanyo lunokushiywa ngokubona komenzi ukuba nje imibhobho iyanelisa ukuxhathisa okucacisiweyo.
I-specimen ifakwe phakathi kweeplatifomu ezimbini kwaye ifakwe kwi-compression de umgama H phakathi kwamaqonga ufikelele kwixabiso elichaziweyo.Lo mzekelo ujongwa ukuba awunazo iintanda.
H=(1+e)t/(e+t/D)
H: umgama phakathi kweeplatens (mm)
t: Ubukhulu bodonga lombhobho (mm)
D: ngaphandle kwedayamitha yombhobho (mm)
е: rhoqo kuchazwe kwibakala ngalinye lombhobho: 0.08 ye-STS370, 0.07 ye-STS410 kunye ne-STS480.
Uvavanyo lokuBendability
Isebenza kwimibhobho ene-diameter yangaphandle ≤50 mm njengoko kuchazwe ngumthengi.
I-specimen iya kukhululeka kwiintanda xa igobile kwi-angle ye-90 ° kunye nobubanzi bangaphakathi be-6 amaxesha angaphandle kombhobho.I-angle yokugoba iya kulinganiswa ekuqaleni kokugoba.
Uvavanyo lweHydrostatic okanye uvavanyo olungonakalisiyo
Uvavanyo lwe-hydrostatic okanye olungonakalisi luya kwenziwa kumbhobho ngamnye.
Uvavanyo lweHydrostatic
Bamba umbhobho ongekho ngaphantsi kobuncinci obuchaziweyo bovavanyo lwe-hydrostatic ubuncinane imizuzwana emi-5 kwaye ukhangele ukuba umbhobho unokumelana noxinzelelo ngaphandle kokuvuza.
Xa uMthengi engakhankanyi uxinzelelo lovavanyo, kwaye xa umbhobho uphantsi koxinzelelo oluncinci lovavanyo lwe-hydrostatic olunikiweyo, umbhobho uya kukwazi ukumelana nawo ngaphandle kokuvuza.
Ubukhulu bodonga lwegama | 40 | 60 | 80 | 100 | 120 | 140 | 160 |
Ubuncinci boxinzelelo lovavanyo lwe-hydraulic, iMpa | 6.0 | 9.0 | 12 | 15 | 18 | 20 | 20 |
Xa ubukhulu bodonga lobubanzi obungaphandle bombhobho wensimbi abukho ixabiso eliqhelekileyo kwitheyibhile yobunzima bombhobho wensimbi, kuyimfuneko ukusebenzisa ifomula ukubala ixabiso loxinzelelo.
P=2st/D
P: uxinzelelo lovavanyo (MPa)
t: Ubukhulu bodonga lombhobho (mm)
D: ngaphandle kwedayamitha yombhobho (mm)
s: 60 % yexabiso elincinci lenqaku lesivuno okanye ubungqina boxinzelelo olunikiweyo.
Xa ubuncinci boxinzelelo lovavanyo lwe-hydrostatic lwenani lesicwangciso esikhethiweyo lidlula uxinzelelo lovavanyo lwe-P olufunyenwe yifomula, uxinzelelo lwe-P luya kusetyenziswa njengoxinzelelo oluncinci lovavanyo lwe-hydrostatic endaweni yokukhetha olona xinzelelo luphantsi lovavanyo lwe-hydrostatic kwitheyibhile engentla.
Uvavanyo olungonakalisi
Umbhobho uya kuhlolwa ngokufunyaniswa kwe-ultrasonic okanye ukufunyanwa kwe-eddy yangoku.
Kwiimpawu zokufumanisa i-ultrasonic, izibonakaliso zeesampulu zereferensi eziqulethe imigangatho yereferensi yeklasi ye-UD echazwe kwi-JIS G 0582 iya kuthathwa njengenqanaba le-alamu, kwaye akukho signali elingana okanye enkulu kunenqanaba le-alamu liya kubakho.
Kwiimpawu ze-eddy zangoku zokubona, umqondiso wesampulu yereferensi equlethe umgangatho wesalathiso weklasi ye-EY njengoko kucacisiwe kwi-JIS G 0583 iya kuthathwa njengenqanaba le-alamu, kwaye akukho signali elingana okanye enkulu kunenqanaba le-alamu liya kubakho.
I-JIS G 3455 Itshathi yobunzima boMbhobho wentsimbi kunye neeShedyuli zemibhobho
Itshathi yobunzima bombhobho wentsimbi
Kwimeko yemilinganiselo engachazwanga kwiitafile zobunzima bombhobho, ifomyula ingasetyenziselwa ukubala.
W=0.02466t(Dt)
W: ubunzima beyunithi yombhobho (kg/m)
t: Ubukhulu bodonga lombhobho (mm)
D: ngaphandle kwedayamitha yombhobho (mm)
0.02466: into yokuguqula ukufumana iW
Qikelela ukuxinana kwe-7.85 g/cm³ kwityhubhu yentsimbi kwaye ujikeleze umphumo ukuya kumanani amathathu abalulekileyo.
Iishedyuli zombhobho
Umgangatho uxela iireyithingi ezintlanu zeShedyuli 40, 60, 80, 100, 120, kunye ne-160.
Ukwenzela lula, nantsi eyona shedyuli iqhele ukusetyenziswa 40 kunye neshedyuli 80.
I-JIS G 3455 Ukunyamezelwa kweDimensional
Imbonakalo
Indawo yangaphakathi nangaphandle yombhobho iya kuba lula kwaye ikhululekile kwiziphene ezingathandekiyo ukuyisebenzisa.
Iziphelo zombhobho wensimbi ziya kuba kwii-angles ezichanekileyo kwi-axis yombhobho.
Ukumakisha
Ityhubhu nganye iya kubhalwa ngolu lwazi lulandelayo.
a) Uphawu lwebakala;
b) Uphawu lwendlela yokuvelisa;
Umbhobho wentsimbi ongenamthungo ogqityiweyo oshushu: -SH
Umbhobho wentsimbi ongenamthungo ogqityiweyo obandayo: -SC
c) ImilinganiseloUmzekelo 50AxSch80 okanye 60.5x5.5;
d) Igama lomenzi okanye uphawu lokuchonga.
Xa i-diameter yangaphandle yetyhubhu nganye incinci kwaye kunzima ukuphawula ityhubhu nganye, okanye xa umthengi efuna ukuba inyanda nganye yeetyhubhu imakishwe, inyanda nganye inokumakishwa ngendlela efanelekileyo.
