Q345R Siab Vessel Phaj
Q345R steel yog lub zog tawm los ntawm 340MPa qib siab lub nkoj tshwj xeeb phaj, nrog cov khoom siv zoo thiab cov txheej txheem ua haujlwm. Phosphorus thiab sulfur cov ntsiab lus yog qis dua cov alloy siab zog steel Q345 (16Mn) steel, ntxiv rau tensile lub zog, elongation yuav tsum tau zoo dua Q345 (16Mn) steel, tab sis kuj yuav tsum tau ua kom muaj zog toughness. Nws yog tam sim no siv dav tshaj plaws, qhov loj tshaj plaws ntawm cov hlab ntsha tshwj xeeb steel siab.

Q345R steel boiler phaj vuam yam ntxwv
Thaum qhov sib piv ntawm cov qoob loo tsawg dua lossis sib npaug rau 0.75, ntau dua 0.8 yuav muaj kev pheej hmoo siab dua ntawm kev tawg. Preheating ntawm steel phaj vuam tsis tas yuav tsum tau. Thaum cov hlau phaj thickness tsawg dua los yog sib npaug li 34, thaum steel phaj thickness> 34, preheating rau 100 ~ 150 degree, ntxiv rau vuam kub kho yuav tsum tau muab tshem tawm tom qab kev ntxhov siab, cua kub ntau yam ntawm 600 ~ 640 degree, feem ntau yog cua - txias thiab ces insulated rauv 40℃txias.
Thaum cov ntsiab lus hauv zos yam tsawg kawg nkaus ntawm Q345R steel welding yeej tsis muaj kev txwv nruj hauv online, vim nws qhov superheat rhiab heev yog tsis siab, txias cracking nyiam yog tsawg, tab sis vim lub superheated cheeb tsam ntawm plasticity thiab toughness yog zoo dua, me me linear zog yog zoo dua.
Thaum welding Q345R steels nrog cov ntsiab lus carbon ntau dua, cov ntsiab lus martensite nce vim muaj kev xav kom quench, uas ua rau muaj kev nce rau hauv kev nyiam txias ntawm cov hlua cable zog thiab embrittlement ntawm cheeb tsam superheated ua hnyav, thiab qhov loj ntawm lub zog offline qhov zoo dua qhov no.
