Lub ci ci annealed raj yog ib hom hlau raj uas tau dhau los ua ib qho kev kub ntxhov - kev kho mob hu ua ci annealing.
1. Cov txheej txheem ntawm Bright Annealing
Bright annealing yog ua tib zoo tswj cov cua sov - txoj kev kho mob. Lub raj yog rhuab mus rau qhov kub thiab txias, feem ntau nyob rau hauv ib qho chaw tiv thaiv xws li hydrogen los yog hydrogen - nitrogen sib tov. Cov cua no tiv thaiv kev tsim cov oxides ntawm lub raj. Cov cua sov yog ua los txo cov kev ntxhov siab hauv cov khoom siv hauv cov raj, uas tuaj yeem tshwm sim thaum lub sijhawm tsim khoom xws li txias - ua haujlwm lossis vuam. Tom qab ncav cuag qhov kub thiab txias, lub raj yog maj mam txias. Cov txheej txheem txias qeeb no yog qhov tseem ceeb vim nws pab ua kom zoo dua microstructure ntawm cov hlau, uas ua rau cov khoom siv kho kom zoo dua qub.
2. Qhov tshwm sim thiab zoo
Ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws ntawm lub raj annealed yog nws ci thiab du nto. Qhov tsis muaj oxides vim qhov chaw tiv thaiv thaum lub sij hawm annealing muab lub raj ci, iav - zoo li tiav. Qhov no tsis tsuas yog ua rau lub raj aesthetically pleasing tab sis kuj muaj cov tswv yim zoo. Hauv kev siv qhov chaw huv thiab du yog qhov tseem ceeb, xws li hauv cov khoom noj thiab dej haus kev lag luam rau cov kav dej lossis hauv kev kho mob rau cov khoom siv tubing, cov raj zoo nkauj annealed yog qhov nyiam heev. Lub ntsej muag du kuj txo qhov kev pheej hmoo ntawm cov kab mob los yog ib qho adhesion, uas yog qhov tseem ceeb hauv kev tu cev.
3. Mechanical Properties
Ci ntsa iab annealed raj muaj cov khoom zoo heev. Txoj kev ntxhov siab - tshem tawm cov txheej txheem thaum lub sij hawm annealing txhim khu lub ductility ntawm lub raj. Qhov no txhais tau hais tias lub raj tuaj yeem khoov lossis tsim tau yooj yim dua yam tsis muaj kev tawg lossis tawg. Lub microstructure refined kuj tseem txhawb nqa lub zog tensile zoo dua thiab toughness. Piv txwv li, nyob rau hauv kev tsim kho ntawm high-pressure piping systems, kev sib xyaw ua ke ntawm zoo ductility thiab lub zog nyob rau hauv ci annealed hlab tso cai rau lawv mus tiv thaiv lub sab hauv thiab sab nraud rog yam tsis ua hauj lwm.
4. Cov ntawv thov
Cov raj no pom kev siv dav hauv ntau yam kev lag luam. Hauv kev lag luam automotive, lawv tau siv rau cov roj kab thiab cov tshuab hydraulic vim lawv tsis kam tiv thaiv corrosion thiab zoo mechanical zog. Nyob rau hauv kev lag luam semiconductor, ci ntsa iab annealed hlab yog siv rau kev thauj mus los ntawm high - purity gases thiab tshuaj vim hais tias ntawm lawv cov huv thiab tsis - reactive nto. Tsis tas li ntawd, nyob rau hauv lub architecture thiab sab hauv tsim teb, lawv ci ntsa iab tsos ua rau lawv haum rau cov hom phiaj zoo nkauj xws li handrails thiab curtain rods.
