Cov tshuaj muaj pes tsawg leeg ntawm25MnG boiler steel yeeb nkabyog qhov yooj yim. Tsuas yog cov ntsiab lus carbon thiab manganese ntau dua, tus so zoo ib yam li 20G. Yog li ntawd, nws lub zog tawm los yog kwv yees li 20% siab dua li ntawm 20G, thaum nws cov plasticity thiab toughness yog sib npaug rau 20G. Cov hlau muaj cov txheej txheem tsim khoom yooj yim thiab ua haujlwm kub thiab txias zoo. Siv nws los ntawm 20G tuaj yeem nyias phab ntsa tuab, txo cov khoom siv, thiab txhim kho cov cua sov hloov ntawm lub boiler. Nws qhov chaw siv thiab kev siv kub yog qhov zoo ib yam li cov 20G boiler raj. Nws yog tsuas yog siv rau cov phab ntsa dej-txias, cov khoom lag luam, cov cua kub qis thiab lwm yam khoom siv nrog kev ua haujlwm kub hauv qab 500 degree.

25MnG steel yeeb nkab ntev
1.Usual ntev: Qhov ntev ntev ntawm cov yeeb nkab steel yog 4000 mm ~ 12 000 mmo
* Tom qab kev sib tham ntawm tus neeg muag khoom thiab tus neeg yuav khoom, thiab tau teev tseg hauv daim ntawv cog lus, cov kav hlau steel nrog qhov ntev ntau dua 12000 mm lossis luv dua 4000 mm tab sis tsis pub tsawg dua 3000 mm tuaj yeem xa tuaj: Qhov ntau ntawm cov kav hlau steel nrog qhov ntev luv dua. 4000 hli tab sis tsis pub tsawg tshaj 3000 hli yuav tsum tsis txhob tshaj 5% ntawm tag nrho cov khoom xa tuaj kom muaj nuj nqis ntawm cov hlau batch.
2.Fixed ntev thiab ntau qhov ntev: Raws li qhov yuav tsum tau ua ntawm tus neeg yuav khoom, tom qab kev sib tham ntawm tus neeg muag khoom thiab tus neeg yuav khoom, thiab tau teev nyob rau hauv daim ntawv cog lus, cov yeeb nkab steel tuaj yeem xa tuaj rau qhov ntev ntev lossis ob npaug ntev. . Qhov tso cai sib txawv ntawm qhov ntev ntev ntawm cov yeeb nkab steel yog +1mm, thiab cov nyiaj tso cai yuav tsum tau tso tseg rau txhua ob qhov ntev raws li hauv qab no: a) Thaum D<159 mm, the notch allowance is 5mm~10mm; b)D>159mm Thaum twg, qhov kev txiav txim siab yog 10mm ~ 15mm.
25MnG carbon steel yeeb nkab hydraulic kuaj
Cov kav hlau yuav tsum tau kuaj hydraulically ib los ntawm ib qho. Lub hydraulic ntsuas siab yog xam raws li tus qauv. Qhov ntsuas siab tshaj plaws yog 20 MPa. Nyob rau hauv qhov kev sim siab, lub sij hawm stabilization yuav tsum tsis pub tsawg tshaj 10 s, thiab cov yeeb nkab steel yuav tsum tsis txhob xau.
