Gulu la Zitsulo Zosapanga dzimbiri

Chitsulo chosapanga dzimbiri chikhoza kugawidwa kukhala chitsulo chosapanga dzimbiri cha austenitic, chitsulo chosapanga dzimbiri cha ferritic, chitsulo chosapanga dzimbiri cha martensitic ndi chitsulo chosapanga dzimbiri cha duplex molingana ndi kapangidwe kake ka metallographic.

(1) Chitsulo chosapanga dzimbiri cha Austenitic

Kutentha kwa chipinda cha austenitic chitsulo chosapanga dzimbiri ndi austenite, chomwe chimapangidwa powonjezera faifi tambala ku chitsulo chosapanga dzimbiri cha chromium.

Chitsulo chosapanga dzimbiri cha Austenitic chili ndi mawonekedwe okhazikika a austenite pokhapokha Cr ili ndi pafupifupi 18%, Ni 8% mpaka 25%, ndi C pafupifupi 0.1%. Chitsulo chosapanga dzimbiri cha Austenitic chimakhazikitsidwa ndi aloyi yachitsulo ya Cr18Ni9. Ndi ntchito zosiyanasiyana, zitsulo zisanu ndi chimodzi za austenitic zosapanga dzimbiri zapangidwa.

Mitundu yodziwika bwino yachitsulo chosapanga dzimbiri cha austenitic:
(1) 1Cr17Mn6Ni15N; (2) 1Cr18Mn8Ni5N; (3) 1Cr18Ni9; (4) 1Cr18Ni9Si3; (5) 06Cr19Ni10; (6) 00Cr19Ni10; (7) 0Cr19Ni9N; (8) 0Cr19Ni10NbN; (9) 00Cr18Ni10N; (10) 1Cr18Ni12; (11) 0Cr23Ni13; (12) 0Cr25Ni20; (13) 0Cr17Ni12Mo2; (14) 00Cr17Ni14Mo2; (15) 0Cr17Ni12Mo2N; (16) 00Cr17Ni13Mo2N; (17) 1Cr18Ni12Mo2Ti; (18) 0Cr; 1Cr18Ni12Mo3Ti; (20) 0Cr18Ni12Mo3Ti; (21) 0Cr18Ni12Mo2Cu2; (22) 00Cr18Ni14Mo2Cu2; (23) 0Cr19Ni13Mo3; (24) 00Cr19Ni13Mo3; (25) 0Cr18Ni16Mo5; (26) 1Cr18Ni9Ti; (27) (29) 0Cr18Ni; 0Cr18Ni13Si4;

Chitsulo chosapanga dzimbiri cha Austenitic chili ndi kuchuluka kwa Ni ndi Cr, zomwe zimapangitsa kuti chitsulocho chikhale chokhazikika kutentha. Ili ndi pulasitiki yabwino, yolimba, yowotcherera, kukana kwa dzimbiri komanso zinthu zopanda maginito kapena zofooka zamaginito. Ili ndi kukana bwino kwa dzimbiri mu oxidizing ndi kuchepetsa media. Amagwiritsidwa ntchito popanga zida zolimbana ndi asidi, monga zotengera zolimbana ndi dzimbiri ndi zida zomangira ndi zoyendera. Mapaipi, zida za nitric acid zosagwira zida, etc., zitha kugwiritsidwanso ntchito ngati zida zazikulu zodzikongoletsera. Chitsulo chosapanga dzimbiri cha Austenitic nthawi zambiri chimatenga chithandizo chamankhwala, ndiko kuti, chitsulocho chimatenthedwa mpaka 1050 mpaka 1150 ° C, kenako chimatenthedwa ndi madzi kapena kuziziritsidwa ndi mpweya kuti mupeze gawo limodzi la austenite.

(2) chitsulo chosapanga dzimbiri

Ambiri ntchito makalasi a ferritic zosapanga dzimbiri zitsulo: (1) 1Cr17; (2) 00Cr30Mo2; (3) 00Cr17; (4) 00Cr17; (5) 1Cr17Mo; (6) 00Cr27Mo;

Chitsulo chosapanga dzimbiri cha Ferritic ndi chitsulo chosapanga dzimbiri chomwe kapangidwe kake kamakhala ndi ferrite kutentha kwapakati. Chromium zili 11% -30%, kukana dzimbiri, kulimba ndi weldability kuwonjezeka ndi kuchuluka chromium zili, kloride nkhawa dzimbiri kukana ndi bwino kuposa mitundu ina ya zitsulo zosapanga dzimbiri, mtundu wa zitsulo zambiri alibe faifi tambala, nthawi zina Lilinso ndi pang'ono Mo, Ti, Nb ndi zinthu zina. Chitsulo chamtunduwu chimakhala ndi mawonekedwe amphamvu yamatenthedwe, kukulitsa kocheperako, kukana kwa okosijeni wabwino, komanso kukana kwa dzimbiri kupsinjika. Amagwiritsidwa ntchito kwambiri popanga kukana kwamlengalenga, mpweya wamadzi, madzi ndi ma oxidizing acid. Zigawo zowonongeka. Komabe, mphamvu zamakina ndi magwiridwe antchito ndizosauka, ndipo zimagwiritsidwa ntchito kwambiri m'mapangidwe osamva acid omwe ali ndi nkhawa pang'ono komanso ngati zitsulo zotsutsana ndi oxidation. Itha kupanganso magawo omwe amagwira ntchito pakutentha kwambiri, monga zida zamagetsi zamagetsi.
