Nta ntawmQ355B-Z15 H kab teeb:
Q355B-Z15 H beams, raws li hom tshwj xeeb ntawm qis- alloy siab- lub zog cov qauv hlau, tsom rau kev txhim kho kev ua tau zoo nyob rau hauv cov kev taw qhia tuab thiab tiv thaiv lamellar tearing.
**Clear Z-qhia kev ua tau zoo**
Nws ua raws li GB / T 5313 tus qauv. "Z15" qhia tau hais tias qhov txo qis ntawm cheeb tsam nyob rau hauv lub thickness kev taw qhia (Z- kev taw qhia) ntawm cov hlau yog ntau tshaj los yog sib npaug zos rau 15%, ua rau nws tiv taus tensile tearing nyob rau hauv lub thickness kev taw qhia thiab tiv thaiv interlaminar tawg ntawm lub phaj vim muaj kev nyuaj siab concentration thaum vuam.
**Stricent Impurity Control**
Cov ntsiab lus impurity yog qis dua li cov qauv hlau zoo tib yam. Tsis yog-cov khoom siv hlau (xws li sulfides) hauv cov hlau matrix raug txo, ua kom cov neeg kho tshuab txuas ntxiv mus rau qhov tuab ntawm cov hauv paus hniav.
** Kev Ua Phem Zoo rau Lamellar Tearing **
Tsim tshwj xeeb rau tuab- phaj vuam, nws tsim nyog rau cov qauv uas yuav tsum tau tiv thaiv qhov nro perpendicular mus rau lub phaj nto (xws li ntau- kev taw qhia cov pob qij txha), tiv thaiv lamellar tev nyob rau hauv tshav kub - cuam tshuam cheeb tsam ntawm vuam.
** Sib npaug zog thiab toughness **
Lub zog tawm los yog ntau dua lossis sib npaug rau 355MPa, lub zog tensile yog 470 - 630MPa, thiab qhov cuam tshuam absorbed zog ntawm -20℃yog Ntau tshaj lossis sib npaug rau 34J. Nws tsis tsuas yog ua tau raws li qhov xav tau ntawm lub zog siab, tab sis kuj muaj peev xwm tiv taus qhov tawg ntawm qhov kub thiab txias.
Thaum txias dabtsi yog khoov los yog stamping tuab daim hlau (Ntau dua los yog sib npaug li 30mm), nws yog ib qho tsim nyog yuav tsum tau kuaj cov pwm raug thiab deformation ua ntej kom tsis txhob muaj cov micro- puas tsuaj los ntawm qhov nyuaj dua me ntsis.
**Industrial thiab Energy Engineering**
Thick -phaj kab hauv steelmaking nroj tsuag, nuclear zog siab hlab ntsha, thiab cov hauv paus ntawm forging presses loj yuav tsum tau tiv taus kub, hnyav, thiab vuam kev nyuaj siab.
**Marine thiab Transportation Engineering**
Cov phaj hauv qab ntawm cov nkoj, tuab - phaj pob qij txha ntawm tus ntoo khaub lig- hiav txwv txuas hniav, thiab qhov chaw txuas ntawm cov hlau loj loj yuav tsum ua kom tau raws li qhov yuav tsum tau muaj zog thiab dej hiav txwv corrosion.
Lub zog tshiab lub tsheb tsim cov phiaj xwm siv Q355B-Z15 H beams qis- alloy siab- lub zog steel tsim los ntawm GNEE Group. Cov kev txhawb nqa steel kab thiab steel truss qauv ntawm qhov project no feem ntau tau txais Q355B-Z15 H beams qis- alloy siab- lub zog steel, nrog rau tag nrho cov kev siv ntawm kwv yees li 20,000 tons kom tau raws li qhov yuav tsum tau nruj ntawm lub zog tshiab tsheb tsim lub hauv paus rau loj {{13} thiab siab load{13}.
Nrog rau ntau tshaj 18 xyoo ntawm kev paub, GNEE muaj kev nkag siab tob txog qhov puas tau - hloov pauv ntawm kev lag luam hlau, ua rau peb txiav txim siab paub thiab muab cov lus qhia zoo rau peb cov neeg siv khoom. Peb tau cog lus los muab cov khoom zoo tshaj plaws steel. Peb cov kev tswj xyuas nruj nruj kom ntseeg tau tias txhua yam khoom tawm hauv lub Hoobkas ua tau raws li cov qauv nruj tshaj plaws thoob ntiaj teb.
Ntxiv rau cov khoom lag luam saum toj no, peb kuj muab ntau yam khoom siv hlau kom tau raws li qhov kev xav tau sib txawv. Yog tias koj muaj kev xav tau, thov hu rau peb ntawmbeam@gneesteel.com.
