Hnub no, kev lag luam steel muaj kev nplua nuj heev. Thiab nyob rau hauv no hais txog, nws yog ib qho nyuaj heev los xaiv raws nraim cov qib steel uas yog haum rau ib tug tshwj xeeb project. Koj yuav tsum delve rau hauv lub ncauj lus, kawm cov yam ntxwv, xav txog ntau yam kev xaiv ib zaug, vam tias yuav nrhiav tau cov khoom tsim nyog.
Nyob rau hauv tsab xov xwm no, peb yuav ua kom lub neej yooj yim dua me ntsis rau cov neeg uas tab tom nrhiav cov khoom steel rau lawv cov haujlwm. Peb yuav tham txog steel 235, heev heev thiab revered nyob rau hauv lub tshav pob ntawm hlau lug. Peb yuav sim piav qhia raws li qhov ua tau txhua yam tseem ceeb tshaj plaws ntsig txog qib steel no.
GOST
Txhua txhua qib steel muaj cov ntaub ntawv qhia meej txog nws cov tshuaj lom neeg thiab lub cev, nrog rau cov peev txheej thiab cov kev xav tau rau kev ua haujlwm. Steel 235 yog tsis muaj kev zam, GOST 27772 muab tag nrho cov ntaub ntawv hais txog qib no, tab sis ua ntej ntawm tag nrho cov, peb tsuas yog txaus siab rau ib co ntawm nws.
Nyob rau hauv qhov muaj pes tsawg leeg ntawm ib qho ntawm cov hlau, tsis hais nws lub hom phiaj, yuav muaj ntau yam tshuaj tsim los rautxhim kho cov qauv ntawm cov hlau thiab muab cov hlau uas tau txais nrog txhua yam khoom, txawm tias nws yog lub zog, ductility, tsis kam rau sab nraud cuam tshuam thiab ntau ntxiv.
Kev paub koj tus kheej nrog cov ntsiab lus ntawm cov hlau alloying ntawm 235, koj tuaj yeem txiav txim siab nws lub cev, nrog rau qee yam tshuaj lom neeg, nrog rau qhov me me ntawm qhov yuam kev.
235th yog tus yam ntxwv ntawm cov hauv qab no:
- 0, 2% carbon.
- 0.6% manganese.
- 0.05% silicon.
- 0, 3% chromium.
- 0, 3% npib tsib xee.
- 0, 3% tooj.
Los ntawm qhov tsis zoo impurities, cov ntsiab lus me me ntawm leej faj tuaj yeem paub qhov txawv - 0.05%, phosphorus - 0.04% thiab 0.08% arsenic.
Raws li koj tuaj yeem pom, cov tshuaj muaj pes tsawg leeg ntawm 235 steel tsis muaj cov khoom zoo. Txawm li cas los xij, nws tsim nyog lees paub rau koj tias qhov no tsis tsim nyog hauv thaj chaw ntawm nws daim ntawv thov thiab, ntawm qhov tsis sib xws, cov khoom siv tau yooj yim dua yuav raug nqi ntau dua.
yam ntxwv ntawm steel 235
Daim ntawv thov tseem ceeb ntawm cov hlau no yog kev tsim cov qauv hlau. Tias yog vim li cas nws thiaj li txawv kiag li, cov kev cai tshwj xeeb. Rau xws li cov qauv hlau, tsis muaj zog yog qhov tseem ceeb dua, tab sis ductility, tsis kam mus rau kev ntxhov siab thiab tus txheeb ze softness, uas zoo heev simplifies nws cov txheej txheem yog tias tsim nyog. Tshwj xeeb tshaj yog, rau steel 235, tus yam ntxwv feature yog lub zog tawm los ntawm qhov ntau ntawm 190 txog 230 megapascals nrog elongation ntawm kev tawg hauv cheeb tsam ntawm 22%.
Qhov taw qhia tseem ceeb tom ntej rau cov hlau ncaj qha rau kev siv ntau yamcov qauv, yog nws cov weldability. Qhov zoo dua thiab yooj yim dua cov txheej txheem vuam yog, qhov zoo dua nws yog, feem. Thiab steel 235 yog npaj txhij los thov craftsmen nrog nws unlimited weldability. Qhov no txhais tau hais tias ob qhov chaw tuaj yeem welded ua ke yam tsis muaj preheating thiab tom qab ntawd tempering los txo kev ntxhov siab hauv cov hlau. Nyob rau tib lub sijhawm, cov seam nws tus kheej tuaj yeem siv los ntawm txhua txoj hauv kev muaj rau tus tswv, thiab qhov zoo ntawm kev sib txuas yuav nyob twj ywm tsis hloov.
Analogues
Zoo hmoo rau ntau, lub tsev lag luam steel tsis yog qhov tsis zoo rau cov hlau zoo sib xws hauv lawv cov khoom thiab cov khoom sib xyaw. Qib 235 kuj muaj qhov zoo sib xws "cov kwv tij ntxaib".
Nco ntsoov: txhua qib ntawm cov qib no muaj ntau heev thiab paub tseeb tias muaj ntau ntau hauv txhua lub lag luam koom nrog kev tsim thiab muag cov khoom steel.
Thaum kawg ntawm kab lus no, kuv xav sau tag nrho cov lus saum toj no. Hlau 235 tej zaum yog ib qho ntawm cov qauv zoo tshaj plaws rau cov qauv welded. Nws yog ib qho yooj yim rau txheej txheem, welded yooj yim thiab ntseeg tau, thiab cov qauv muaj peev xwm tiv taus siab loads ntev yam tsis muaj kev tawg.

Qhov chaw ua lag luam nyob qhov twg thiab lub sijhawm twg nws ua haujlwm, koj tuaj yeem pom hauv kab lus
Txhua yam hais txog Boeing 747. Los yog yuav luag txhua yam
Boeing 747, pom tau yooj yim los ntawm nws lub fuselage hunchbacked, yog qhov tseeb los ntawm kev tsim tub rog los ntawm xyoo 1970s. Lub sijhawm ntawd, tsoomfwv Meskas xav tau lub dav hlau thauj khoom hnyav, uas tau tshaj tawm kev sib tw. Txawm li cas los xij, Boeing tsis tau txais kev txiav txim ua tub rog
