Kev hloov ntawm Manganese (Mn) Element Cov ntsiab lus

 

Tsim nyog nce los txhim kho cov khoom: Hauv NV D - qib steel daim hlau, qhov tsim nyog nce hauv cov ntsiab lus manganese tuaj yeem txhim kho weldability. Cov ntsiab lus manganese feem ntau yog nyob rau hauv ib qho chaw (xws li 0.9% - 1.6%). Yog hais tias cov ntsiab lus ntawm manganese yog tsim nyog nce nyob rau hauv no ntau yam, piv txwv li, ze rau lub sab sauv txwv, nws yuav zoo dua refine cov nplej. Thaum lub sij hawm vuam txheej txheem, cov nplej refined pab txhim kho lub toughness thiab lub zog ntawm lub welded sib koom tes thiab txo cov embrittlement tshwm sim nyob rau hauv lub tshav kub - cuam tshuam cheeb tsam. Nyob rau tib lub sijhawm, manganese tuaj yeem ua ke nrog cov sulfur los tsim manganese sulfide (MnS), txo cov kev phom sij ntawm cov sulfur ntawm kub brittleness ntawm cov hlau thiab ua rau cov txheej txheem vuam zoo dua.

 

Zam Txim Ntau Tshaj: Txawm li cas los xij, cov ntsiab lus ntawm manganese yuav tsum tsis txhob siab dhau. Yog tias cov ntsiab lus ntawm manganese siab dhau lawm, nws yuav ua rau muaj qhov tsis sib xws hauv lwm cov khoom ntawm cov hlau. Piv txwv li, cov ntsiab lus ntawm manganese ntau dhau yuav ua rau kev sib cais ntawm cov hlau, cuam tshuam rau tag nrho cov hlau phaj zoo. Ntxiv mus, thaum lub sij hawm welding, nws yuav hloov lub solidification hom ntawm vuam hlau thiab ua rau muaj kev pheej hmoo ntawm vuam tsis xws luag.

 

Kev hloov ntawm Molybdenum (Mo) Element Cov ntsiab lus

 

Tswj cov ntsiab lus kom txo cov tawv nqaij tawv: Txij li thaum molybdenum yuav ua rau kom lub zog ntawm cov cua sov - cuam tshuam cheeb tsam thaum vuam, hauv NV D - qib steel daim hlau, cov ntsiab lus ntawm molybdenum caij yuav tsum tau ua tib zoo tswj. Yog hais tias cov ntsiab lus molybdenum siab dhau lawm, lub tshav kub - cuam tshuam cheeb tsam yog feem ntau yuav ua rau nyuaj thiab nkig lug xws li bainite los yog martensite thaum lub sij hawm vuam txias txheej txheem, yog li txo qhov toughness ntawm welded sib koom ua ke thiab ua rau muaj kev pheej hmoo ntawm vuam tawg tiam. Yog li ntawd, nyob rau hauv lub premise ntawm ua tau raws li lub zog thiab corrosion - kuj yuav tsum tau ntawm steel phaj, txo cov molybdenum cov ntsiab lus ntau npaum li sai tau tuaj yeem txhim kho weldability.

 

Optimization ntawm Alloy Proportion: Kev ua haujlwm ntawm molybdenum tuaj yeem hloov pauv qee yam los ntawm lwm cov ntsiab lus los ntawm kev ua kom zoo ntawm cov alloy feem. Piv txwv li, tsim nyog nce cov ntsiab lus ntawm manganese thiab npib tsib xee thiab lwm cov ntsiab lus tuaj yeem txo qhov cuam tshuam tsis zoo ntawm molybdenum ntawm lub hardening nyiam ntawm tshav kub - cuam tshuam cheeb tsam thaum vuam thaum ua kom zoo ntawm cov phaj steel.

Kev hloov kho ntawm Lwm Yam Khoom (xws li Titanium (Ti), Niobium (Nb), thiab lwm yam)

 

Micro- alloying muaj nuj nqi: Qee cov kab lus tuaj yeem ua kom zoo dua qhov kev sib txuas ntawm NV D - qib steel daim hlau los ntawm micro- alloying. Piv txwv li, titanium thiab niobium tuaj yeem tsim cov carbides lossis nitrides thaum lub sijhawm ua cov hlau. Cov tebchaw no tuaj yeem ua lub luag haujlwm hauv pinning cov ciam teb thaum lub sij hawm vuam thermal voj voog, tiv thaiv cov nplej los ntawm kev loj hlob, yog li refining cov nplej thiab txhim kho lub toughness ntawm welded sib koom.

 

Precise Control ntawm Cov Nyiaj Ntxiv: Qhov sib ntxiv ntawm cov kab no feem ntau yog me me thiab yuav tsum tau tswj kom meej. Ntxiv ntau dhau tuaj yeem ua rau muaj kev nce ntxiv hauv kev suav nrog thiab lwm yam teeb meem, cuam tshuam rau qhov zoo thiab weldability ntawm steel phaj; ntxiv me ntsis dhau yuav tsis tuaj yeem ua nws lub luag haujlwm. Feem ntau, cov ntsiab lus ntawm cov kab lus no tau hloov kho los ntawm cov hlau zoo - ua cov txheej txheem thiab kev ua haujlwm zoo - txhais tau tias tswj.
