Mene ne na kowa hanyoyin annealing na na’ura mai saurin motsa jiki

1. Cikewar da ba ta cika ba: Rashin cikawa tsari ne na kawar da baƙin ƙarfe-carbon alloy zuwa matsakaicin zafin jiki na Ac1-Ac3 don cimma rashin cikar martensitization, sannan a hankali sanyaya. Annealing da bai cika ba ya fi dacewa da matsakaici, matsakaicin ƙarfe na carbon da babban kayan ƙarfe na ƙarfe, da dai sauransu;

2. Spheroidizing annealing: dumama karfe zuwa zafin jiki dan kadan kasa ko sama da Ac1 ko canza yanayin zafi a kusa da A1 na wani lokaci, sannan a hankali sanyaya. Spheroidizing annealing ana amfani da shi don rage babban tauri na gami karfe da No. 45 karfe bayan simintin gyaran kafa;

3. Isothermal annealing: ana amfani da shi don rage girman taurin wasu kayan aikin ƙarfe tare da manyan abubuwan nickel da chromium don aiwatar da aikin hakowa da sarrafawa;

4. Cikakkiyar cirewa: ingantacciyar tsarin zafin jiki mai ƙarfi tare da ƙarancin kaddarorin jiki bayan ƙirƙira, simintin simintin gyare-gyare da waldawar lantarki na babban ƙarfe na carbon;

5. Ƙaddamar da damuwa na ƙasa: ana amfani da shi don cire damuwa na zafi na simintin ƙarfe da walda;

6. External diffusion annealing: amfani da su homogenize da abun da ke ciki na aluminum gami simintin gyaran kafa da kuma inganta su yi Manuniya;

7. Annealing aiki hardening: Ana amfani da shi don cire taurin yanayin ƙarfe na wayoyi da zanen ƙarfe a cikin duka aikin zane mai sanyi da jujjuyawar sanyi, da kuma cire tasirin aikin sanyi don sassauta kayan ƙarfe.

1. Graphitization annealing: Ana amfani da na’ura mai saurin jujjuyawa don juyar da ƙarfe na alade tare da siminti mai yawa zuwa ƙarfe na simintin gyare-gyare tare da ingantaccen nakasar filastik. Bayan dumama zuwa wani zazzabi, zafi rufi na wani ɗan lokaci sannan kuma matsakaicin sanyaya, ta yadda siminti ya narke don samar da flocculent high-purity graphite.
