27simniityhubhu zentsimbi ezingenamthungo, oktIityhubhu zentsimbi ezingama-27SiMn ezingenamthungo, zezinye zezixhobo zemibhobho yentsimbi engenamthungo.Umxholo wekhabhoni uphakathi kwe-0.24 kunye ne-0.32%.Umqolo we-simin omnye kungenxa yezinto ezintlanu (i-carbon C, i-silicon Si kunye ne-manganese).Kwi-Mn, i-phosphorus P, kunye ne-sulphur S, umxholo we-silicomanganese malunga ne-1.10 ukuya kwi-1.40%.Umbhobho we-27simn ongenamthungo ufanelekile kwiplanti yamandla, iplanti yebhoyila, ishishini lemichiza, imoto, izixhobo zenqanawa.
I-27simn yensimbi engenamthungo ithiyori yobunzima befomula yentsimbi engenamthungo ityhubhu ngemitha yobunzima W=0.02466*S(DS)
Intsingiselo yeSimboli: D = I-diameter yangaphandle S = Ubungakanani bodonga umzekelo wokubala: Kwipayipi yensimbi engenamthungo kunye nobubanzi obungaphandle be-60mm kunye nobukhulu bodonga lwe-4mm, bala ubunzima nge-m.
Ubunzima ngem=0.02466*4*(60-4)=5.52Kg

Ixabiso leetyhubhu zentsimbi ezingenamthungo limalunga ne-500-800 yuan / itoni ephezulu kunelo leetyhubhu ezidityanisiweyo ezithe tye, kwaye ixabiso lemibhobho yentsimbi engenamthungo yi-800-1200 yuan/toni ephezulu kunomthungo wentsimbi. Inkqubo yokuvelisa umbhobho wentsimbi engenamthungo. |Umbhobho wentsimbi engenamthungo uphunyezwa ikakhulu ngokunciphisa utsalo, kunye nenkqubo yokunciphisa utsalo yinkqubo eqhubekayo yokuqengqeleka apho isiseko sentsimbi singenamandrel.Kwisiseko sokuqinisekisa umgangatho we-welding yombhobho womama, inkqubo yokunciphisa uxinzelelo lombhobho odityanisiweyo kukufudumeza wonke umbhobho odityanisiweyo ukuya kuma-950 degrees celsius okanye ngaphezulu, kwaye ke kwiindidi zeedayamitha zangaphandle neendonga i-tension reducer (i-24 iyonke idlula i-stretch reducer).Ityhubhu engqindilili egqityiweyo, ityhubhu yentsimbi eshushu eqengqelekayo eveliswe yile nkqubo kunye nombhobho odityanisiweyo oqhelekileyo we-high-frequency wahluka ngokubalulekileyo.Emva kokufudumeza kwisithando somlilo, isakhiwo se-metallographic kunye neempawu zemishini ye-weld kunye nentsimbi yomzali inokuhambelana ngokupheleleyo.Isinciphisi sesibini sokunciphisa uxinzelelo kunye nolawulo oluzenzekelayo lwenza ukuchaneka kobukhulu bombhobho (ingakumbi ukujikeleza kombhobho kunye nokuchaneka kobunzima bodonga) ngcono kunombhobho ofanayo ongenamthungo.Iityhubhu zolwelo kunye neetyhubhu zebhoyila eziveliswe kumazwe aphuhlileyo kwihlabathi ziye zamkela inani elikhuluityhubhu edityanisiweyo iinkqubo ezingenamthungo.Ngophuhliso loluntu, iityhubhu ezidityanisiweyo ezishushu zasekhaya ziye zatshintsha ngokuthe ngcembe iityhubhu ezingenamthungo.
Umbhobho wentsimbi ongenamthungo luhlobo lwentsimbi yecandelo elide kunye necandelo elingenanto kwaye akukho mthungo ngeenxa zonke.I-Steel inecandelo elingenanto, inani elikhulu lemibhobho esetyenziselwa ukuthutha ulwelo, njengokuhanjiswa kweoli, igesi yendalo, igesi, amanzi kunye nezinye izinto eziqinileyo ezifana nemibhobho.Umbhobho ongenamthungo wahlulwe ube yimibhobho eqengqelekayo eshushu, iityhubhu eziqengqelekayo ezibandayo, iityhubhu ezitsalwa ngokubanda, iityhubhu ezikhutshiweyo, ukugqobhoza kwemibhobho.Umbhobho wentsimbi ongenamthungo wokuhambisa ulwelo usetyenziselwa ukuthutha amanzi, i-oyile, igesi kunye nolunye ulwelo oluqhelekileyo lombhobho wentsimbi ongenamthungo.Umbhobho wensimbi ongenamthungo ophantsi nophakathi usetyenziswa ekwenzeni izakhiwo ezahlukeneyo zebhoyila yoxinzelelo oluphantsi nophakathi imibhobho yomphunga eshushu kakhulu, imibhobho yamanzi abilayo kunye netyhubhu yebhoyila eshushu kakhulu, umbhobho womsi, umbhobho omncinci kunye nombhobho wezitena we-arch onomgangatho ophezulu. carbon structure Steel hot-rolled kwaye kubanda-drawn intsimbi umthungo umbhobho.Umahluko phakathi kweetyhubhu zentsimbi ezingenamthungo zolwelo kunye neetyhubhu zentsimbi ezingenamthungo kwizibilisi zoxinzelelo oluphantsi naphakathi: Umahluko phakathi kwe-GB / T8163-1999 kunye netyhubhu yentsimbi engenamthungo yeetyhubhu zentsimbi ezilwelo ezingenamthungo kunye nezibiyeli zoxinzelelo oluphantsi noluphakathi. ityhubhu yentsimbi engenamthungo enecandelo elinomngxuma ngaphandle kokujikeleza Umcu omde wentsimbi.I-Steel inecandelo elingenanto, inani elikhulu lemibhobho esetyenziselwa ukuthutha ulwelo, njengokuhanjiswa kweoli, igesi yendalo, igesi, amanzi kunye nezinye izinto eziqinileyo ezifana nemibhobho.Umbhobho ongenamthungo wahlulwe ube yimibhobho eqengqelekayo eshushu, iityhubhu eziqengqelekayo ezibandayo, iityhubhu ezitsalwa ngokubanda, iityhubhu ezikhutshiweyo, ukugqobhoza kwemibhobho.Umbhobho wentsimbi ongenamthungo wokuhambisa ulweloisetyenziselwa ukuthutha amanzi, i-oyile, igesi kunye nolunye ulwelo ngokubanzi umbhobho wentsimbi ongenamthungo.Umbhobho wensimbi ongenamthungo ophantsi nophakathi usetyenziswa ekwenzeni izakhiwo ezahlukeneyo zebhoyila yoxinzelelo oluphantsi nophakathi imibhobho yomphunga eshushu kakhulu, imibhobho yamanzi abilayo kunye netyhubhu yebhoyila eshushu kakhulu, umbhobho womsi, umbhobho omncinci kunye nombhobho wezitena we-arch onomgangatho ophezulu. carbon structure Steel hot-rolled kwaye kubanda-drawn intsimbi umthungo umbhobho.
