Zachitsulo zosapanga dzimbiri:

Zachitsulo zosapanga dzimbiri ndi mtundu wa zakuthupi, ali pafupi ndi galasi kuwala, kukhudza kwambiri ndi kuzizira, wa zinthu avant-garde zokongoletsera kwambiri, ali kwambiri dzimbiri kukana, akamaumba, ngakhale ndi kulimba ndi makhalidwe ena mndandanda, ntchito makampani katundu , mafakitale opepuka, mafakitale ogulitsa katundu wapakhomo ndi zokongoletsera zomanga ndi mafakitale ena.

Chitsulo chosapanga dzimbiri chosapanga dzimbiri chomwe chimatchedwa chitsulo chosapanga dzimbiri, chimapangidwa ndi chitsulo chosapanga dzimbiri ndi chitsulo chosapanga dzimbiri mbali ziwiri, mwachidule, chimatha kukana kuwonongeka kwa mlengalenga kwachitsulo chotchedwa chitsulo chosapanga dzimbiri, ndipo chimatha kukana kuwononga mankhwala apakati achitsulo otchedwa acid resistant steel. kulankhula, chromium zili Cr ndi wamkulu kuposa 12% ya zitsulo ali ndi makhalidwe zitsulo zosapanga dzimbiri.

Gulu lachitsulo chosapanga dzimbiri:

Pali njira zambiri zogawira zitsulo zosapanga dzimbiri, zomwe zimakhala zofala kwambiri ndi izi.

Gulu la Metallographic Design:

Akhoza kugawidwa mu austenitic zitsulo zosapanga dzimbiri, ferrite chitsulo chosapanga dzimbiri, martensitic chitsulo chosapanga dzimbiri, duplex chitsulo chosapanga dzimbiri, mpweya wowumitsa chitsulo chosapanga dzimbiri.

Gulu la Chemical:

Kwenikweni atha kugawidwa mu chromium zosapanga dzimbiri zitsulo (monga ferrite mndandanda, martensite dongosolo) ndi chromium faifi tambala zitsulo zosapanga dzimbiri (monga austenite dongosolo, abnormal mndandanda, mpweya kuumitsa mndandanda) machitidwe awiri.

Malingana ndi mtundu wa corrosion resistance:

Iwo akhoza kugawidwa mu nkhawa dzimbiri kugonjetsedwa zitsulo zosapanga dzimbiri, dzenje dzimbiri kugonjetsedwa zitsulo zosapanga dzimbiri, intergranular dzimbiri kugonjetsedwa zitsulo zosapanga dzimbiri, etc.

Zimagawidwa ndi magwiridwe antchito:

Itha kugawidwa kukhala chitsulo chosapanga dzimbiri chaulere, chitsulo chosapanga dzimbiri chosapanga maginito, chitsulo chosapanga dzimbiri chotsika, chitsulo chosapanga dzimbiri champhamvu kwambiri.

Pali mitundu pafupifupi 100 yazitsulo zosapanga dzimbiri zomwe zaphatikizidwa mumiyezo yosiyanasiyana padziko lapansi, komanso kupita patsogolo kwa sayansi ndi ukadaulo komanso chitukuko cha mafakitale ndi ulimi, magiredi atsopano achitsulo chosapanga dzimbiri akuwonjezekanso. , chromium yofanana ndi [Cr] ndi nickel yofanana ndi nickel [Ni] ikhoza kuwerengedwa molingana ndi kapangidwe kake ka mankhwala, ndipo microstructure ndi katundu wa chitsulo akhoza kuyesedwa pafupifupi pogwiritsa ntchito tchati cha Schaeffler-Delong chosapanga dzimbiri chosapanga dzimbiri.

Gulu la matrix:

1, chitsulo chosapanga dzimbiri cha ferrite.Chromium 12% ~ 30%.Kukana kwake kwa dzimbiri, kulimba kwake komanso kuwotcherera kumawonjezeka ndi kuchuluka kwa chromium, ndipo kukana kwake kwa dzimbiri kwa chloride kuli bwino kuposa mitundu ina yazitsulo zosapanga dzimbiri.

2. Austenitic chitsulo chosapanga dzimbiri.Ili ndi chromium yoposa 18%, pafupifupi 8% nickel ndi molybdenum, titaniyamu, nayitrogeni ndi zinthu zina.

3. Austenite-ferrite duplex chitsulo chosapanga dzimbiri.Ili ndi ubwino wa austenite ndi ferrite chitsulo chosapanga dzimbiri, ndipo ili ndi superplasticity.

Martensitic zosapanga dzimbiri zitsulo.Mkulu mphamvu, koma pulasitiki osauka ndi weldability.

Chitsulo chosapanga dzimbiri muyezo zitsulo nambala poyerekeza tebulo ndi kachulukidwe tebulo
