Ityhubhu yesikwereluhlobo lwetyhubhu yentsimbi, ekwabizwa ngokuba yityhubhu yesikwere,ityhubhu yoxande.Inkcazo yayo ibonakaliswe nge-mm yobubanzi obungaphandle * ubukhulu bodonga.Yenziwe ngentsimbi eshushu eqengqelekayo ngokuqengqeleka okubandayo okanye umzobo obandayo.
Ukusetyenziswa kombhobho wesikwere ongenamthungo:
Isikwere esingenamthungo kunyeyuantai tube rectangularzisetyenziswa ngokubanzi.Ngokuqhelekileyo isetyenziselwa ukwenza iinxalenye zesakhiwo kunye namalungu omatshini, afana nombhobho we-oyile, i-shaft yokuhambisa i-automobile, isakhelo sebhayisikile kunye ne-scaffolding yentsimbi esetyenziselwa ulwakhiwo, ezenziwe ngentsimbi ephezulu ye-carbon structural steel ngokuqengqeleka okushushu okanye umzobo obandayo. ubukhulu becala isetyenziswa njengemibhobho okanye amalungu esakhiwo ukuthutha ulwelo.
Uhlobo lwetyhubhu engenamthungo yoxande:
1. Ngokwezinto eziphathekayo, inokwahlulwa ibe yintsimbi yesakhiwo sekhabhoni eqhelekileyo kunye ne-alloy ephantsi yamandla aphezulu ensimbi yesakhiwo.Umxholo wekhabhoni wangaphambili awuyi kudlula i-4.5%;isulfure ≤ 0.035;i-phosphorus ≤ 0.005;ichromium ≤ 0.15;umxholo we-nickel <0.25;ubhedu ≤ 0.30;Le yokugqibela iqulethe inani elincinci le-silicon, i-manganese kunye ne-vanadium ngaphezu kwekhabhoni, isulfure, i-phosphorus kunye ne-chromium.
2. Ngokomgangatho womphezulu:
(1) Gqiba:
I-1 Imigangatho yangaphakathi nangaphandle yetyhubhu yesikwere engenamthungo iya kuba lula kwaye icwecwe ngaphandle kwamaqamu kunye nemibimbi.
2 Xa indawo yangaphakathi yangaphakathi ingaphantsi kwe-100 mm2, ukunyamezela okuvumelekileyo kwendawo yangaphakathi ± 0.2 mm.
3 Xa indawo yangaphakathi yangaphakathi ingaphezulu kwe-100 mm2, ukunyamezela okuvumelekileyo kwendawo yangaphakathi ± 0.5 mm.
4 Akukho zintanda okanye ukugotywa kuvunyelwe kumphezulu ongaphakathi;5 Akuyi kubakho mikrwelo icacileyo, akukho mikrwelo icacileyo;
(2) Ukucaba:
1 Imiphezulu yangaphakathi nangaphandle yeetyhubhu zesikwere ezingenamthungo ziya kuba mcaba kwaye zigude.
2 Kufuneka kungabikho ukungalingani okucacileyo xa kujongwa ngeglasi yokukhulisa i-10X.
3 Isiphelo sobuso bombhobho si-perpendicular kumgca ophakathi wombhobho.
4 Ubuso besiphelo sombhobho ophakathi abuyi kuba neentsimbi.
5 Makungabikho mibimbi ejikeni lombhobho.
6 Iziphelo zombini zombhobho ziya kuhambelana.
7 Akukho qhuma licacileyo livumelekileyo kwi weld emva kokususwa komhlwa.
8 Makungabikho mihadi icacileyo.
9 Akukho ziphene ezichaphazela ukusetyenziswa zivumelekile.
10 Xa i-plate rolling machine isetyenziselwa i-welding, i-fillet radius kwi-weld ayiyi kuba ngaphantsi kobunzima besiseko sesinyithi.
(3) Ukuchaneka komgangatho:
I-1 Impazamo yokujikeleza ayiyi kudlula ukuphambuka okukhulu okuchazwe kumgangatho ohambelanayo ngaphezu kwe-2 mm / m2.
2 Ukuchaneka kunye nokuphambuka kwe-angle akuyi kudlula i-1/20 ye-deviation ephezulu echazwe kumgangatho ohambelanayo.
3 Ukutenxa komda wobude abuyi kuba mkhulu kunamaxesha e-1.5 exabiso elihambelanayo elichaziweyo.
Ulawulo lomgangatho weumbhobho wentsimbi yuantaiingqongqo kakhulu, ke abathengi banokukhetha ngokuzithemba.Inkampani yeYuantaiUfumene amalungelo awodwa omenzi wechiza angama-77,Yuantai intsimbiuphumelele intshatsheli enye ye-rectangular tube industry iminyaka eli-10 ilandelelana,
Ukuba ufuna ukufumanaixabiso lombhobho wentsimbi yuantai,Nceda uqhagamshelane nathi.
