THOV VESSEL STEEL Plate

Lub siab lub nkoj steel phaj yog cov khoom siv tseem ceeb hauv ntau qhov kev lag luam, ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov hlab ntsha siab uas siv los ntim thiab tswj cov khoom hauv siab. Cov hlau phaj no tau tsim tshwj xeeb los tiv thaiv cov kev xav tau thiab cov neeg kho tshuab kev ntxhov siab cuam tshuam nrog kev tswj cov siab.

Lub zog ntawm cov hlab ntsha steel phaj yog qhov tseem ceeb tshaj plaws. Lawv yuav tsum muaj lub zog tensile siab los tiv thaiv lub zog los ntawm lub zog sab hauv. Tsis tas li ntawd, lawv yuav tsum muaj ductility zoo heev kom haum rau txhua qhov muaj peev xwm deformation yam tsis muaj kev tawg. Toughness yog lwm yam yam ntxwv tseem ceeb, ua rau cov hlau nqus lub zog thiab tiv thaiv kev tawg tawm, tshwj xeeb tshaj yog thaum muaj kev cuam tshuam tam sim lossis kev thauj khoom dynamic.

Cov tshuaj muaj pes tsawg leeg ntawm siab hlab ntsha steel daim hlau yog ua tib zoo tswj kom ua tau raws li qhov xav tau txhua yam khoom. Cov ntsiab lus alloying xws li manganese, chromium, molybdenum, thiab npib tsib xee tau ntxiv rau hauv cov nqi meej los txhim kho lub zog, hardenability, thiab corrosion kuj. Cov ntsiab lus tsawg ntawm impurities xws li sulfur thiab phosphorus yog qhov tseem ceeb los tiv thaiv embrittlement thiab txhim kho weldability.

Kev tsim cov txheej txheem ntawm cov hlab ntsha steel phaj yog qhov nyuaj thiab meej. Cov hlau feem ntau yog tsim los ntawm cov txheej txheem xws li hluav taws xob arc rauv melting lossis cov pa oxygen yooj yim rauv smelting, tom qab ntawd los ntawm kev ua kom zoo dua ntxiv kom huv si ntxiv. Kub dov thiab tswj cua txias yog ua hauj lwm kom tau qhov xav tau microstructure, uas muaj peev xwm muaj xws li ferrite, pearlite, bainite, los yog martensite, nyob ntawm seb cov kev cai tshwj xeeb.

Kev tswj kom zoo yog ib feem tseem ceeb ntawm kev tsim cov hlab ntsha steel phaj. Kev soj ntsuam nruj thiab cov txheej txheem tshuaj xyuas yog ua kom ua raws li cov qauv kev lag luam thiab cov kev qhia tshwj xeeb. Kev ntsuam xyuas tensile, kev ntsuam xyuas cuam tshuam, kev sim hardness, thiab tsis muaj kev puas tsuaj xws li kev kuaj ultrasonic thiab kev tshuaj xyuas cov khoom sib nqus yog siv los kuaj xyuas cov teeb meem lossis kev hloov pauv hauv cov khoom siv.

Lub siab lub nkoj steel phaj yog cais raws li lawv cov khoom siv kho tshuab, tshuaj muaj pes tsawg leeg, thiab kev kho cua sov. Cov qib feem ntau suav nrog ASTM A516, A537, thiab EN 10028. Txhua qib yog tsim los ua kom tau raws li cov kev xav tau tshwj xeeb thiab qhov kub thiab txias rau kev siv sib txawv.

Hauv kev lag luam roj thiab roj, lub siab lub nkoj steel phaj yog siv rau hauv kev tsim kho cov tank, cov kav dej, thiab cov khoom siv refinery. Lawv yuav tsum tiv taus cov kev kub ntxhov thiab corrosive ib puag ncig cuam tshuam nrog kev thauj mus los thiab kev ua cov hydrocarbons. Hauv kev lag luam tshuaj, lawv tau ua haujlwm hauv cov reactors, cov hlab ntsha, thiab cov khoom siv hluav taws xob los tswj cov tshuaj lom neeg ntau yam.

Kev lag luam nuclear tso siab rau ntawm cov hlab ntsha steel phaj rau kev ntim cov khoom siv hluav taws xob thiab kev ua haujlwm ntawm nuclear reactors. Cov phiaj no yuav tsum tau ua raws li cov qauv kev nyab xeeb nruj heev thiab tiv taus cov xwm txheej tshwj xeeb ntawm ib puag ncig nuclear.

Kev xaiv ntawm lub siab tsim nyog lub nkoj steel phaj nyob ntawm ntau yam, nrog rau kev khiav hauj lwm siab, qhov kub thiab txias, nruab nrab nyob rau hauv, thiab tsim lub neej ntawm lub nkoj. Engineering xam thiab tsim kev txiav txim siab yog qhov tseem ceeb los xyuas kom meej qhov kev ncaj ncees thiab kev nyab xeeb ntawm lub nkoj siab thoob plaws hauv nws lub neej ua haujlwm.

Kev nce qib hauv cov ntaub ntawv kev tshawb fawb thiab kev tsim cov thev naus laus zis niaj hnub ua rau kev txhim kho hauv cov hlab ntsha steel phaj. Cov txheej txheem tshiab thiab cov txheej txheem ua tiav tau tsim los txhim kho kev ua tau zoo thiab ua haujlwm ntev ntawm cov ntaub ntawv no, thaum tseem txo cov nqi thiab txhim kho kev tsim khoom.

Hauv kev xaus, lub siab lub nkoj steel daim hlau yog ib qho tseem ceeb hauv ntau qhov kev lag luam uas muaj kev nyab xeeb ntawm cov khoom nyob rau hauv siab yog qhov tseem ceeb tshaj plaws. Lawv cov khoom, cov txheej txheem tsim khoom, thiab kev tswj xyuas zoo yog txhua yam tsim los ua kom ntseeg tau thiab ua haujlwm ntev ntawm cov hlab ntsha siab, tiv thaiv ob tus neeg ua haujlwm thiab ib puag ncig. Kev tshawb fawb txuas ntxiv thiab kev tsim kho tshiab hauv daim teb no yuav ua rau muaj kev nce qib siab dua thiab txhim khu kev ntseeg siab ntawm cov hlau phaj rau yav tom ntej.
