Cov tsos ntawm Q235 thiab Q345 feem ntau tsis pom. Cov xim sib txawv tsis muaj dab tsi cuam tshuam nrog cov khoom siv ntawm cov hlau, tab sis yog tshwm sim los ntawm cov txheej txheem txias sib txawv tom qab cov hlau tau dov tawm. Feem ntau, qhov saum npoo yog xim liab tom qab ntuj txias. Yog tias siv txoj kev ua kom txias sai, qhov saum npoo tsim cov txheej oxide tuab, uas yuav pom cov xim dub.
Kev tsim lub zog dav dav nrog Q345, vim tias Q345 dua li Q235 steel siab zog, txuag steel, tshaj 235 txuag 15 feem pua - 20 feem pua. Txhawm rau tswj kev ruaj ntseg tsim nrog Q235 yog qhov zoo. Tus nqi sib txawv ntawm 3 feem pua --- 8 feem pua .
Raws li kev txheeb xyuas, muaj ob peb nqe lus:
1, Lub Hoobkas tuaj yeem siv qhov ntsuas vuam kom paub qhov txawv ntawm ob yam khoom. Piv txwv li, nyob rau hauv ob daim hlau phaj nrog E43 vuam pas nrig tau welded ib tug me me puag ncig steel, thiab ces siv shear quab yuam, raws li kev puas tsuaj ntawm qhov teeb meem no roughly paub qhov txawv ntawm ob steel phaj khoom.
2, Lub Hoobkas tseem tuaj yeem siv lub log sib tsoo kom paub qhov txawv ntawm ob yam khoom. q235 steel nrog sib tsoo log sib tsoo, lub txim taws yog ib puag ncig, thaum Q345 sparks yog bifurcated.
3, kuj tseem muaj raws li qhov sib txawv ntawm cov xim sib txawv ntawm ob lub steel shear nto kuj tuaj yeem sib txawv ntawm ob lub hlau. Feem ntau, cov xim ntawm Q345 shear lub qhov ncauj yog dawb
4, Raws li cov xim ntawm cov hlau phaj tuaj yeem paub qhov txawv ntawm Q235 thiab Q345 cov khoom: Q235 xim yog ntsuab, Q345 qee qhov liab (qhov no tsuas yog rau cov hlau uas nyuam qhuav nkag mus rau hauv lub tshav pob, thiab tsis tuaj yeem sib txawv tom qab lub sijhawm ntev)
5, Cov khoom siv sib txawv tshaj plaws yog kev tshuaj xyuas tshuaj, Q235 thiab Q345 carbon cov ntsiab lus tsis zoo ib yam, thaum cov ntsiab lus tshuaj kuj txawv. (Qhov no yog txoj hauv kev uas tuaj yeem ua tsis tau)
6, Qhov sib txawv ntawm Q235 thiab Q345 cov khoom, nrog vuam: ob daim ntawm cov khoom siv tsis paub steel phaj taub qab, nrog cov vuam zoo tib yam rau vuam, yog tias sab ntawm cov phaj steel nrog cov kab nrib pleb yog pov thawj tias Q345 khoom. (Qhov no yog kev xyaum ua)
