Q345R Hlau Daim Hlau Ntawm Lub Nkoj Siab

Thaum cov txiaj ntsig tau qis 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 steel phaj thickness tsawg dua los yog sib npaug rau 34, preheat rau 100 ~ 150 degree thaum steel phaj thickness yog> 34, ntxiv rau tshem tawm kev ntxhov siab yog xav tau tom qab vuam kev kho cua sov, cua kub ntau yam 600 ~ 640 degree, feem ntau cua txias tom qab tshav kub. preservation rauv txias kom qis dua 400 degree.

Thaum cov pa roj carbon ntsiab lus ntawm ib feem tsawg kawg nkaus Q345R steel vuam yooj yim tsis muaj kev txwv nruj ntawm kab, rau nws yog overheating rhiab heev yog tsis siab, txias cracking nyiam yog tsawg, tab sis rau qhov zoo ntawm plasticity thiab toughness overheated cheeb tsam, me me linear zog yog zoo dua.

Thaum vuam Q345R steel ntawm cov ntsiab lus carbon nyob rau sab siab, rau lub hardening tendency nce, cov ntsiab lus ntawm martensite nce, nws yuav ua rau cov hlua cable zog txias cracking nyiam, embrittlement ntawm overheated cheeb tsam kuj yuav loj, qhov teeb meem no yog offline zog ib feem. loj dua.
