Chitoliro cha Chitsulo Chosapanga Dzimbiri Chomwe Chili ndi Annealed: Chifukwa Chake Chithandizo cha Mayankho N'chofunika

Chiyambi

Chitoliro Chosapanga Dzimbiri Chopangidwa ndi Annealedndi chitoliro chachitsulo chosapanga dzimbiri chopanda msoko kapena cholumikizidwa chomwe chatenthedwa kufika kutentha koyenera kwa yankho ndipo chimaziziritsidwa pamlingo wolamulidwa kuti chibwezeretse kukana dzimbiri, kusinthasintha komanso kapangidwe ka zitsulo kofanana. Pa mitundu ya austenitic monga 304L ndi 316L, solution annealing imasungunula ma carbide okhala ndi chromium yambiri ndikuchepetsa chiopsezo cha dzimbiri lokhudzana ndi sensitization. Pa zitsulo zosapanga dzimbiri ziwiri, zimathandizanso kukhazikitsa bwino pakati pa austenite ndi ferrite.

Chitoliro cholumikizidwa chimagwiritsidwa ntchito pokonza mankhwala, zida za chakudya ndi zakumwa, makina opangira mankhwala, malo opangira mafuta ndi gasi, zosinthira kutentha, kukonza madzi, mapaipi am'madzi ndi ntchito yamadzimadzi oyera kwambiri. Ogula ayenera kufotokoza mtundu wake, muyezo wa chinthucho, kapangidwe kosasunthika kapena kolumikizidwa, miyeso, momwe kutentha kumakhalira, kutha kwa pamwamba, zofunikira pakuyesa dzimbiri ndi satifiketi yowunikira.

Kodi Annealing Imachita Chiyani pa Chitoliro cha Chitsulo Chosapanga Dzimbiri?

Kujambula kozizira, kupanga, kuwotcherera ndi kugwiritsa ntchito kutentha kumasintha kapangidwe ka chitoliro chachitsulo chosapanga dzimbiri. Ntchitozi zitha kuyambitsa kupsinjika kotsalira, kuuma kwa ntchito, kutsika kwa chromium-carbide kapena kusalinganika bwino kwa gawo. Kuthira yankho kumagwiritsidwa ntchito kubwezera zinthuzo pamalo oyenera ntchito yolimbana ndi dzimbiri komanso kupanga pambuyo pake.

Kusungunula Chromium Carbides

Zitsulo zosapanga dzimbiri za Austenitic zimatha kupanga ma chromium carbides zikayikidwa pamalo otentha kwa nthawi yokwanira. Chromium imachokera kumadera ozungulira omwe ali ndi malire a tirigu, zomwe zimapangitsa kuti chromium iwonongeke. Madera amenewa akhoza kukhala pachiwopsezo cha dzimbiri pakati pa granular m'malo ovuta.

Pa nthawi yokonza madzi, chitolirocho chimatenthedwa mokwanira kuti chisungunuke ma carbide awa kubwerera ku austenitic matrix. Kuziziritsa mwachangu kenako kumachepetsa mvula yatsopano. Kuzungulira kwa kutentha kumadalira mtundu, makulidwe a gawo, kapangidwe ka uvuni ndi momwe zinthuzo zimagwiritsidwira ntchito.

Kubwezeretsa Kugwira Ntchito Pambuyo pa Kuzizira

Chitoliro chokokedwa ndi ozizira chimakhala ndi mphamvu zambiri komanso kuuma chifukwa cha kuuma kwa strain, koma kutalika kwake ndi kupangika kwake kumachepa. Kuyika chitolirocho kumathandiza kuti chiwonjezeke, kuchepetsa kuuma kwake ndikubwezeretsa mphamvu. Izi ndizofunikira pamene chitolirocho chidzapindidwa, kukulitsidwa, kuphulika, kuwotcherera kapena kupangidwa kukhala chogwirira cha zida.

Kulamulira Kulinganiza kwa Duplex Phase

Zitsulo zosapanga dzimbiri ziwiri zimakhala ndi ferrite ndi austenite. Kutenthetsa kosayenerera kumatha kupanga ferrite yambiri kapena magawo owopsa a pakati pa zitsulo, kuchepetsa kulimba ndi kukana dzimbiri. Kuthira komaliza kwa yankho lotsatiridwa ndi kuzizira mwachangu mokwanira ndi gawo lofunikira kwambiri popanga chitoliro cha duplex ndi super duplex.
