Umbhobho wensimbi we-40Cr ulungiselelwe ngumenzi
Umbhobho wensimbi engenamthungo (GB / T14975-2002) ngumbhobho oshushu oqengqelekayo (owongeziweyo, owandisiweyo) kunye nombhobho otsalwa ngokubanda (oqengqiwe) owenziwe ngentsimbi engatyiwayo kwimibhobho enganyangekiyo, iinxalenye zesakhiwo kunye neenxalenye zekhemikhali, ipetroleum, ukukhanya. eyokuluka, ezonyango, ekutya, koomatshini kunye namanye amashishini.
Indlela yokubala yombhobho wentsimbi yesakhiwo: (i-diameter yangaphandle - ubukhulu bodonga) * ubukhulu bodonga * 0.02466 = ubunzima bombhobho wentsimbi ngemitha nganye

I-API Spec 5ct-1999 (Inkcazo ye-casing kunye netyhubhu), njl njl. ukuqengqeleka) → umbhobho ongenanto → unyango lobushushu → ukulungisa → uvavanyo lwe-hydrostatic (ukubona iziphene) → ukuphawula → ugcino.
Ukuqengqeleka okushushu (umbhobho wolwakhiwo okhutshiweyo): umbhobho ongqukuva ungenanto → ukufudumeza → ukugqobhoza → ukuqengqeleka okuthathu okuqengqelekayo, ukuqengqeleka okuqhubekayo okanye ukukhutshwa kombhobho → ukuhluba umbhobho → ukulinganisa (okanye ukunciphisa) → ukupholisa → umbhobho ongenanto → ukulungisa → uvavanyo lwe-hydrostatic (okanye ukufumanisa isiphene) → ukuphawula → ugcino.
Umbhobho wolwakhiwo olubandayo usebenzisa i-coil yentsimbi eshushu-isolwe njengesixhobo ekrwada kwaye uqhuba ukuqengqeleka okuqhubekayo okubandayo emva kokucholwa kwe-asidi ukususa isikali se-oxide. Imveliso egqityiweyo yi-coil eqiniweyo. Ngenxa yobunzima bomsebenzi obandayo obangelwa ukuguqulwa okubandayo okuqhubekayo, amandla kunye nobunzima bokunyuka kwekhoyili eqiniweyo kunye nokuqina kunye nesalathisi seplastiki siyancipha. Ke ngoko, ukusebenza kwesitampu kuya kuwohloka kwaye kungasetyenziselwa iindawo ezilula ezinokukhubazeka. Ikhoyili egoqiweyo ingasetyenziswa njengemathiriyeli ekrwada yesityalo sokugalela i-hot-dip, kuba iiyunithi zegalvanizing zediphu ezishushu zixhotyiswe ngemigca yokufunxa. Ubunzima bekhoyili eqiniweyo ngokuqhelekileyo yi-6 ~ 13.5T, kunye nobubanzi bangaphakathi bekhoyili yentsimbi yi-610mm.
Ngokuqhelekileyo, ukucoca ngokuqhubekayo (iyunithi ye-CAPL) okanye intsimbi ye-annealing yesithando somlilo iya kuqhutyelwa kwiipleyiti eziqengqelekayo ezibandayo kunye neekhoyili ukuphelisa ukuqina komsebenzi obandayo kunye noxinzelelo lokuqengqeleka, ukuze kuhlangatyezwane nezalathi zepropathi yomatshini ezichazwe kwimigangatho ehambelanayo.
Umgangatho womphezulu, inkangeleko kunye nokuchaneka kombhobho wolwakhiwo oluqengqelekayo kubanda ungcono kunombhobho wolwakhiwo oqengqelekayo, kwaye ubungqingqwa bemveliso yawo bugoqwe ngokufanelekileyo ukuya malunga ne-0.18mm, ngoko ke ithandwa luninzi lwabasebenzisi. Ukuthatha i-coil yentsimbi epholileyo njengesiseko sombhobho wokulungiswa okunzulu kweemveliso, iye yaba yimveliso ephezulu eyongeziweyo. Okufana ne-electro galvanizing, i-galvanizing eshushu, iminwe exhathisa i-electro galvanizing, i-coil yentsimbi egqunywe ngombala, i-vibration damping composite ipleyiti yentsimbi, ipleyiti yentsimbi egqunywe ngePVC, njl. esetyenziswa ngokubanzi. Ikhoyili yentsimbi ebandayo kufuneka igqitywe emva kokuba ifakwe intsimbi, kuquka ukusika intloko, ukusika umsila, ukusika umphetho, ukulinganisa, ukulinganisa, ukubuyisela umva, okanye ipleyiti yokucheba yobude. Iimveliso eziqengqelekayo ezibandayo zisetyenziswa kakhulu kwimveliso yeemoto, izixhobo zasekhaya, izixhobo zokutshintsha, ulwakhiwo, ifenitshala yeofisi kunye namanye amashishini. Ubunzima bengxowa nganye yeepleyiti zentsimbi yi-3 ~ 5 iitoni. Ubunzima bekhoyili ecaba yi-3 ~ 10 tons / coil. I-diameter yangaphakathi ye-coil yensimbi yi-610mm.
Umbhobho wolwakhiwo oqengqelekayo usebenzisa i-slab eqhubekayo yokuphosa okanye i-blooming slab njengemathiriyeli ekrwada, ethi ifudunyezwe ngokunyathela kwiziko lokufudumeza ize ithotywe ngamanzi anoxinzelelo oluphezulu phambi kokungena kwindawo yokusila. Izinto ezirhabaxa zingena kwi-mill yokugqibezela emva kokusika intloko, umsila kwaye emva koko ungene kwi-mill yokugqibezela ukuqengqeleka okulawulwa yikhompyutha. Emva kokuqengqeleka kokugqibela, iqengqeleka kwikhoyili yeenwele ezithe tye ngokupholisa i-laminar kunye ne-coiler. Intloko kunye nomsila we-curl yeenwele ezithe tye zihlala zibunjwe ngolwimi kunye nomsila wentlanzi omile, ngokuchaneka kakubi kobukhulu kunye nobubanzi, kwaye kukho iziphene ezinje ngokuma kwamaza, i-hem, i-tower shape njalo njalo. Ubunzima bekhoyili bunzima kwaye ububanzi bangaphakathi bekhoyili yensimbi yi-760mm ( Ngokuqhelekileyo, ishishini lombhobho lithanda ukuyisebenzisa.) Emva kokuba i-coil yeenwele ezithe tye icutshungulwe ngokusikwa kwentloko, ukusika umsila, ukunqunyulwa komphetho, ukulungiswa kweendlela ezininzi, ukulinganisa kunye nokulinganisa. eminye imigca yokugqiba, iyasikwa okanye iphinde iguqulwe ibe yipleyiti yentsimbi eshushu, icoil yentsimbi eshushu eshushu, ibhanti lokusika longitudinal kunye nezinye iimveliso. I-coil yokugqiba i-hot-rolled rolling iya kuba yi-coil pickling eshushu edibeneyo ukuba isikali se-oxide sisuswe ngokukhethwa kwaye sifakwe ngeoli. Imveliso inotyekelo lokutshintsha ngokuyinxenye umbhobho wolwakhiwo oluqengqelekayo, ngexabiso eliphakathi, kwaye ithandwa kakhulu luninzi lwabasebenzisi.
