Kuzimya icyuho qu kuzimya icyuma cyumuti wicyuma kitagira umuyaga

Kuzimya, byitwa kandi gukomera ni inzira yo gushyushya hanyuma gukonjesha ibyuma (cyangwa ibindi bivanze) ku muvuduko mwinshi ko hari kwiyongera cyane mubukomere, haba hejuru cyangwa hose.Ku bijyanye no kuzimya vacuum, iki gikorwa gikorerwa mu itanura rya vacuum aho ubushyuhe bugera kuri 1,300 ° C bushobora kugerwaho.Uburyo bwo kuzimya buzatandukana kubijyanye nibikoresho bivurwa ariko kuzimya gaze ukoresheje azote nibisanzwe.

Kuzimya imyuka acu

Mugihe cya gaze ya vacuum Kuzimya, ibikoresho birashyuha mugihe habuze ogisijeni hakoreshejwe convection hagati ya gaze ya inert (N₂) na / cyangwa imirasire yubushyuhe mukibazo.Ibyuma bikomezwa n'umugezi wa azote, aho igipimo cyo gukonjesha gishobora kugenwa no guhitamo umuvuduko ukabije.Ukurikije imiterere yakazi birashoboka nanone guhitamo icyerekezo nigihe cya azote ihuha.Gukwirakwiza igihe hamwe no kugenzura ubushyuhe bwibyuma bikorwa mugihe cyogukoresha hifashishijwe ubushakashatsi bwa termocouples bushobora gushyirwa kumurongo wakazi mubyumba bishyushya.Icyuma gishyuha ubushyuhe buvurwa mu itanura rya vacuum kibona imiterere yihariye yimbaraga nubukomere mugice cyose cyambukiranya, nta decarburisiyasi.Ingano ya Austenitike ni nziza kandi yujuje ubuziranenge mpuzamahanga.

Mubyukuri ibyuma byose bishimishije mubyuma bya tekinike, nkibyuma byamasoko, ibyuma bikonje bikonje, ibyuma bizimya kandi bikonje, ibyuma birwanya ubukana, ibyuma bishyushye bikoreshwa hamwe nicyuma cyibikoresho, hamwe numubare munini wibyuma byinshi-bitavanze cyane kandi bidafite ibyuma. -iron alloys, irashobora gukomera murubu buryo.

Kuzimya Amavuta ya Vacuum

Kuzimya amavuta ya Vacuum ni ugukonjesha ibikoresho bishyushye hamwe namavuta ya Vacuum.Nkuko ihererekanyabubasha rikorwa mugihe cya vacuum cyangwa kurinda inert-gaze nyuma yo gukuramo vacuum yoza itanura, ubuso bwigice burarindwa kugeza bwuzuye mumavuta.Kurinda hejuru birasa cyane niba kuzimya amavuta cyangwa gaze.

Inyungu nyamukuru ugereranije nibisanzwe amavuta yo mu kirere azimya ibisubizo ni kugenzura neza ibipimo bikonje.Hamwe nitanura rya vacuum, birashoboka guhindura ibipimo bisanzwe bizimya - ubushyuhe no guhagarika umutima - ndetse no guhindura umuvuduko uri hejuru yikigega kizimya.

Guhindura umuvuduko uri hejuru yikigega bizatera itandukaniro ryumuvuduko uri imbere yo kwiyuhagira amavuta, uhindura umurongo wo gukonjesha amavuta wasobanuwe kumuvuduko wikirere.Mubyukuri, agace gatetse nicyiciro aho umuvuduko wo gukonja ari mwinshi.Guhindura umuvuduko wamavuta bizahindura imyuka yabyo kubera ubushyuhe bwumutwaro.

Kugabanuka k'umuvuduko bizakora ibintu byo guhumeka, bitangiza icyiciro.Ibi bizongera ubukonje bwo kuzimya amazi no kunoza ubushobozi bwo gukomera hamwe nikirere.Nyamara, ibisekuru byinshi byamazi birashobora gutera sheath phenomenon kandi bigatera guhinduka.

Ubwiyongere bwumuvuduko mumavuta burabuza gukora imyuka kandi bikabuza guhumeka.Urupapuro rufata igice kandi rugakonja cyane ariko ntibikabije.Kuzimya amavuta muri vacuum rero birasa cyane kandi bigoreka bike.

Kuzimya amazi

Inzira nko kuzimya amavuta ya vacuum, Nibisubizo byiza byo gukomera ubushyuhe bwa aluminium, titanium cyangwa ibindi bikoresho bigomba gukonjeshwa ku buryo bwihuse bihagije.
