Kutentha Kuchiza

Kuchiza kutentha ndi gawo lofunikira pakuwongolera molondola.Komabe, pali njira yopitilira imodzi yokwaniritsira, ndipo kusankha kwanu chithandizo cha kutentha kumatengera zida, mafakitale ndi kugwiritsa ntchito komaliza.

Ntchito Zochizira Kutentha

Heat treatment metalHeat treatment ndi njira yomwe chitsulo chimatenthetsera kapena kuziziritsidwa m'malo otetezedwa mwamphamvu kuti chiwongolere zinthu zakuthupi monga kusinthika kwake, kulimba, kupangidwa, kuuma, ndi mphamvu.Zitsulo zothiridwa ndi kutentha ndizofunikira m'mafakitale ambiri kuphatikiza azamlengalenga, magalimoto, makompyuta, ndi zida zolemera.Zigawo zazitsulo zopangira kutentha (monga zomangira kapena mabulaketi a injini) zimapanga phindu popititsa patsogolo kusinthasintha kwake komanso kugwira ntchito kwake.

Chithandizo cha kutentha ndi njira zitatu.Choyamba, chitsulocho chimatenthedwa ndi kutentha kwapadera komwe kumafunika kubweretsa kusintha komwe kukufunika.Kenaka, kutentha kumasungidwa mpaka chitsulocho chatenthedwa mofanana.Kenako gwero la kutentha limachotsedwa, kulola chitsulo kuti chizizizira kotheratu.

Chitsulo ndiye chitsulo chogwiritsidwa ntchito kwambiri ndi kutentha koma izi zimachitika pazida zina:

● Aluminiyamu
● Mkuwa
● Mkuwa
● Chitsulo Choponyera

● Mkuwa
● Mofulumira
● Chotsani

● Nickel
● Pulasitiki
● Chitsulo Chosapanga chitsulo

Njira Zosiyanasiyana Zochizira Kutentha

Kuwumitsa

Kuumitsa kumachitidwa pofuna kuthana ndi zofooka zachitsulo, makamaka zomwe zimakhudza kulimba kwathunthu.Zimachitidwa ndi kutentha zitsulo ndikuzimitsa mwamsanga pamene zifika kuzinthu zomwe zikufunikira.Izi amaundana particles kotero amapeza makhalidwe atsopano.

Annealing

Zofala kwambiri ndi aluminiyamu, mkuwa, chitsulo, siliva kapena mkuwa, annealing imaphatikizapo kutentha zitsulo mpaka kutentha kwambiri, kuzigwira pamenepo ndikuzilola kuti zizizizira pang'onopang'ono.Izi zimapangitsa kuti zitsulozi zikhale zosavuta kugwira ntchito.Mkuwa, siliva ndi mkuwa zimatha kuzizidwa mwachangu kapena pang'onopang'ono, kutengera momwe zagwiritsidwira ntchito, koma chitsulo nthawi zonse chimayenera kuzizirira pang'onopang'ono kapena sichingatseke bwino.Izi nthawi zambiri zimachitika musanapange makina kuti zida zisalephere popanga.

Normalizing

Nthawi zambiri ntchito zitsulo, normalizing bwino machinability, ductility ndi mphamvu.Chitsulo chimatentha mpaka madigiri 150 mpaka 200 kuposa zitsulo zomwe zimagwiritsidwa ntchito popanga annealing ndipo zimasungidwa pamenepo mpaka kusintha komwe kukufunika kuchitika.Njirayi imafuna chitsulo kuti chizizizira kuti chipange mbewu zoyengedwa bwino za ferritic.Izi ndizothandizanso pochotsa mbewu za columnar ndi tsankho la dendritic, zomwe zitha kusokoneza khalidwe pamene mukuponya gawo.

Kutentha

Njirayi imagwiritsidwa ntchito pazitsulo zopangidwa ndi chitsulo, makamaka zitsulo.Ma alloys awa ndi olimba kwambiri, koma nthawi zambiri amakhala osakhazikika pazolinga zawo.Kutentha kumatenthetsa zitsulo mpaka kutentha pansi pa malo ovuta, chifukwa izi zidzachepetsa brittleness popanda kusokoneza kuuma.Ngati kasitomala akufuna pulasitiki yabwino ndi kuuma pang'ono ndi mphamvu, timatenthetsa zitsulo mpaka kutentha kwakukulu.Komabe, nthaŵi zina zipangizo sizimatenthedwa, ndipo zingakhale zosavuta kugula zinthu zomwe zaumitsidwa kale kapena kuziumitsa musanazipange.

Mlandu kuumitsa

Ngati mukufuna malo olimba koma pachimake chofewa, kuyimitsa milandu ndiye kubetcha kwanu kwabwino kwambiri.Izi ndizomwe zimachitika pazitsulo zokhala ndi carbon yochepa, monga chitsulo ndi chitsulo.Mwa njira iyi, chithandizo cha kutentha chimawonjezera carbon pamwamba.Nthawi zambiri mumayitanitsa izi zidutswa zitapangidwa kuti muzitha kuzipanga kukhala zolimba.Amachitidwa pogwiritsa ntchito kutentha kwakukulu ndi mankhwala ena, chifukwa amachepetsa chiopsezo chopangitsa kuti gawolo likhale lolimba.

Kukalamba

Zomwe zimadziwikanso kuti kuuma kwa mpweya, njirayi imawonjezera mphamvu zokolola zazitsulo zofewa.Ngati zitsulo zimafuna kuumitsa kwina kuposa momwe zilili panopa, kuuma kwa mvula kumawonjezera zonyansa kuti ziwonjezere mphamvu.Izi nthawi zambiri zimachitika njira zina zikagwiritsidwa ntchito, ndipo zimangowonjezera kutentha mpaka pakati ndikuziziritsa zinthu mwachangu.Ngati katswiri awona kuti ukalamba wachilengedwe ndi wabwino kwambiri, zida zimasungidwa m'malo ozizira mpaka zitafika zomwe zikufunika.
