Chitsogozo cha Chitsulo Cholimba Kwambiri: Kuchokera ku S355 mpaka S960

Mu dziko la uinjiniya wa zomangamanga, kupitirira chitsulo chokhazikika cha kaboni sikulinso chinthu chapamwamba—ndikofunika kuti chigwire ntchito bwino komanso chikhale chokhazikika. Chitsulo Champhamvu Kwambiri, kapena HSS, chimalola mapangidwe osalimba, kuchepetsa kuchuluka kwa zolumikizira, komanso kuchepetsa ndalama zoyendera.

Komabe, malamulo otchulira mayina a miyezo ya ku Ulaya nthawi zambiri amabweretsa chisokonezo m'sitolo. Kusankha pakati pa S460MLH ndi S460NH sikungokhudza chizindikiro chokha; kumalamulira momwe polojekiti yanu idzagwiritsidwire ntchito, kupangidwa, ndi momwe idzagwirire ntchito kutentha kwapansi pa zero.

—–Kutanthauzira Utsogoleri wa Magiredi———————————

Mtengo wa manambala mu giredi iliyonse ya EN, monga355kapena 960, ikuyimira mphamvu yocheperako yopezera zokolola yomwe imayesedwa mu megapascals. Ngakhale kuti S355 ikadali ntchito yomanga padziko lonse lapansi, makampaniwa akusunthira mwachangu kupita kuS460ndi S690 kuti akwaniritse zolinga zochepetsera kulemera.

Zotsatira za Kukonza: M, N, ndi Q

Kalata yotsatira mphamvu imasonyeza momwe zinthuzo zimaperekedwera, zomwe mwina ndizofunikira kwambiri popanga zinthuzo.

• M-Series (Yozunguliridwa ndi Thermomechanically):Zitsulo zimenezi zimakonzedwa pa kutentha kosiyanasiyana kuti zikhale ndi mphamvu zambiri zokhala ndi kaboni yochepa kwambiri. Izi zimapangitsa kuti chitsulo cha M-series chikhale chosavuta kuchilumikiza, nthawi zambiri chimachotsa kufunika kotenthetsera pasadakhale ngakhale m'zigawo zokhuthala.
• N-Series (Yokhazikika):Njira yachikhalidwe yomwe chitsulo chimakonzedwa ndi kutentha kuti chikhale ndi kapangidwe kofanana. Ndi chokhazikika kwambiri ndipo chimakondedwa ngati chitsulocho chidzatenthedwanso kapena kutenthedwa panthawi yopanga.
• Mndandanda wa Q (Wozimitsidwa ndi Wofatsa):Iyi ndiye muyezo wabwino kwambiri wa mphamvu yapamwamba kwambiri. Mwa kuziziritsa mofulumira kenako n’kutenthetsanso chitsulocho, timapeza mphamvu zokolola kuyambira 690 MPa mpaka 960 MPa. Komabe, mitundu iyi imafuna kuwongolera kutentha kwambiri panthawi yowotcherera kuti zinthuzo zisafewe.

—–Kufunika kwa Kulimba Kochepa————————————

Mphamvu ndi theka chabe la nkhani. Pamene chitsulo chikulimba, mwachibadwa chimakhala chosavuta kusweka. Kuti athetse vutoli, mainjiniya ayenera kuyang'ana mayina a L kapena L1.

Magiredi wamba nthawi zambiri amatsimikizira mphamvu yamagetsi pa -20°C. Ngati polojekiti yanu ikukumana ndi malo ovuta—monga nsanja za m'mphepete mwa nyanja, zida zapamwamba, kapena zomangamanga za arctic—muyenera kusankha MLH kapena NLH kuti igwire ntchito pa -40°C, kapena QL1H yapamwamba kuti igwire ntchito mpaka -60°C.

Kugwiritsa Ntchito Mwanzeru kwa Stee Yamphamvu Kwambiri

--FAQ----------

Q1: Kodi ndingasinthe S355 mwachindunji ndi S960 kuti ndichepetse kulemera?

A1: Sizili choncho kwenikweni. Ngakhale kuti S960 ndi yolimba pafupifupi katatu, njira yolumikizirana yachitsulo imakhalabe yokhazikika. Ngati kapangidwe kanu kali ndi malire chifukwa cha "kupotoka" kapena "kuuma" m'malo mwa "mphamvu," gawo lochepa la S960 lingagwedezeke kapena kugwedezeka kwambiri. Muyenera kusintha mawonekedwe ake kuti mugwiritse ntchito bwino mphamvu zake zapamwamba.

Q2: N’chifukwa chiyani S700MC ndi yosiyana ndi S690QH?

A2; Ngakhale kuti mphamvu zawo ndi zofanana, S700MC idapangidwa makamaka kuti ipange ndi kupindika ozizira. Ndi mbale yozungulira yopangidwa ndi thermomechanically rolled (MC) yomwe imatha kugwira ma radii opindika mwamphamvu popanda kusweka, pomwe zitsulo za Q-series (QH) zimapangidwa bwino kuti zigwirizane ndi magawo obowoka komanso mbale zolemera komwe mphamvu ya brute load ndiyo yofunika kwambiri.

Q3: Kodi kuwotcherera kumakhudza mphamvu ya S960?

A4: Inde. Zitsulo zolimba kwambiri zimadalira kutentha koyenera. Ngati "cholowetsa kutentha" cholumikizira cholumikizira chili chokwera kwambiri, chimapanga Malo Ofewa m'dera lomwe lili pafupi ndi cholumikizira. Izi zimachepetsa mphamvu ya malo olumikizirana. Olumikiza ayenera kutsatira njira zokhwima zokhudzana ndi kutentha kwa interpass ndi kuchuluka kwa kuzizira.

Q4: Kodi S460MLH ndi yosavuta kuiwotcherera kuposa S460NH?

A4: Kawirikawiri, inde. Popeza ma MLH grade amagwiritsa ntchito thermomechanical rolling, amapeza mphamvu zawo ndi zinthu zochepa zophatikiza monga carbon ndi manganese. Chofanana ndi carbon chotsikachi chimapangitsa kuti chitsulocho chisamasweke mosavuta ndi hydrogen, nthawi zambiri chimachotsa kufunika kotenthetsera chitsulocho musanachiwotchere.

Q5: Kodi “H” kumapeto kwa magiredi awa ikuyimira chiyani?

A5: H imayimira Hollow Section. Kaya chitolirocho ndi chozungulira, cha sikweya, kapena chamakona anayi, chiganizo cha H chimatsimikizira kuti zinthuzo zikukwaniritsa zofunikira za miyezo ya EN 10210 kapena EN 10219 ya magawo a hollow.
