Jul 28, 2026
Cov qauv hlau tau siv dav hauv kev cob qhia kev lag luam, chaw ntau pob loj, txuas hniav, kev sib txuas lus yees, offshore platforms thiab txawv teb chaws kev tsim kho vaj tse vim lawv cov txiaj ntsig zoo suav nrog lub zog siab, lub teeb tus kheej - hnyav, kev tsim kho ceev ceev thiab qib kev lag luam siab. Raws li lub ntsiab load- bearing tivthaiv ntawm engineering tej yaam num, qhov zoo ntawm steel cov ntaub ntawv ncaj qha txiav txim siab bearing muaj peev xwm, qaug zog tsis kam thiab ntev - lub sij hawm kev pab cuam kev nyab xeeb ntawm tag nrho cov qauv. Kev ntsuas cov khoom siv hlau yog hais txog kev kuaj lub cev thiab tshuaj lom neeg los xyuas cov qib steel, cov tshuaj muaj pes tsawg leeg thiab cov khoom siv ntawm cov khoom siv hlau. Nws ua tau zoo tiv thaiv cov khoom siv tsis zoo hloov pauv thiab daim ntawv thov qib tsis raug, thiab tshem tawm cov teeb meem kev nyab xeeb loj los ntawm lub hauv paus ntawm kev tsim kho engineering.
1. Lub hom phiaj tseem ceeb ntawm cov khoom siv steel qauv kuaj
1.1 Steel Qib Kev Tshawb Fawb & Cov Khoom Siv Sib xyaw- nce Kev Tiv Thaiv
Nws yog ib txwm muaj nyob rau hauv cov chaw tsim kho uas cov khoom siv hlau tiag tiag tsis ua raws li daim ntawv pov thawj zoo, lossis cov qib sib txawv ntawm cov hlau sib xyaw siv (xws li tsis meej pem ntawm Q235 thiab Q355 steel, lossis hloov cov qauv tshwj xeeb steel nrog qis - alloy steel). Kev kuaj cov ntaub ntawv tshaj lij tuaj yeem txheeb xyuas cov qib steel tiag tiag thiab ua qauv rau ntawm - daim ntawv thov cov ntaub ntawv.
1.2 Mechanical Performance Compliance Verification
Kev ntsuam xyuas xyuas tias cov ntsuas tseem ceeb suav nrog kev tawm dag zog, lub zog tensile, elongation thiab cuam tshuam toughness tag nrho raws li cov qauv tsim. Nws ua kom cov haujlwm ruaj khov ntawm cov qauv hlau nyob rau hauv cov khoom zoo li qub, cov khoom siv hluav taws xob thiab qis - qhov chaw ua haujlwm kub.
1.3 Kev Tiv Thaiv Cov Khoom Uas Muaj Teeb Meem & Kev Tiv Thaiv Brittleness
Cov teeb meem ntau dhau xws li sulfur thiab phosphorus yuav yooj yim ua rau txias brittleness, kub brittleness thiab vuam tawg ntawm hlau. Tshuaj muaj pes tsawg leeg tsom xam nruj me ntsis tswj cov kev txwv ntawm impurity ntsiab, kom ntseeg tau zoo heev plasticity thiab vuam kev ua tau zoo ntawm steel cov ntaub ntawv.
1.4 Kev Tso Cai Lij Choj rau Txoj Haujlwm Txais & Kev lis kev cai txawv teb chaws
Thib peb-cov ntawv pov thawj kev soj ntsuam ntawm tog neeg ua haujlwm yog cov ntaub ntawv tseem ceeb rau kev lees paub ua tiav qhov project hauv tsev, kev tshuaj xyuas tus tswv txawv teb chaws thiab kev txiav txim siab zoo hauv kev lag luam steel thoob ntiaj teb.
2. Cov khoom kuaj tseem ceeb rau cov khoom siv hlau
2.1 Chemical Composition Analysis (Core of Material Traceability)
Txais Siv Optical Emission Spectroscopy (OES), portable XRF spectroscopy thiab carbon- kev soj ntsuam cov piam thaj, kev kuaj xyuas cov ntsiab lus tseem ceeb xws li Carbon (C), Silicon (Si), Manganese (Mn), Sulfur (S) thiab Phosphorus (P), nrog rau cov ntsiab lus alloy xws li Chromium, Nickel thiab Molybdenum ntawm kev thov. Nws tuaj yeem paub qhov txawv ntawm cov qauv hlau (Q235 series), siab -lub zog qis- alloy steel (Q355 series) thiab lwm cov qib steel tshwj xeeb. Lub caij no, nws nruj me ntsis tswj cov ntsiab lus ntawm S thiab P impurities los lav kev ua thiab vuam kev ua tau zoo ntawm cov hlau. Ob qho uas tsis yog - puas tsuaj ntawm - kev tshuaj ntsuam xyuas qhov chaw thiab siab - qhov chaw kuaj xyuas qhov tseeb - tshuaj xyuas muaj.
