Cov kev daws teeb meem muaj zog rau kev lag luam loj hlob
Slab ntau lawm: Hloov los ntawm titanium ingot mus rau titanium slab. Titanium daim hlau thiab lwm yam khoom titanium tag nrho yog los ntawm titanium ingots. Lawv yuav tsum tau mus dhau cov txheej txheem forging los ua titanium slabs nrog qhov ntev ntawm 210 * 1100 * 8000mm. Tom qab cov slabs tau tsim, lawv qhov chaw yuav tsum tau kho kom tshem tawm cov txheej dub oxide. Phaj dov: Multi-theem precision processing rau kub dov. 1. Cua sov: Muab cov titanium phaj billet nyob rau hauv ib qho chaw sov so. Qhov tsim nyog cua sov rau titanium daim hlau yog nruab nrab ntawm 900℃thiab 1000 degree. Thaum lub sij hawm ua cua sov, xyuas kom lub sij hawm txaus, nrog rau cov cua sov thiab tuav lub sij hawm mus txog ntau tshaj 4 - 4.5 teev kom paub meej tias cov cua sov ntawm titanium phaj billet thiab npaj rau tom ntej dov . 2. Rough dov: Tom qab cua sov, lub titanium billet yog thawj zaug mus rau siab -lub zog ntawm cov hlau descaling tshuab, ces oxide dov mus rau qhov chaw. rau preliminary shaping. Rough rolling feem ntau yog siv txoj kev thim rov qab, xws li ob- yob lossis plaub- yob yob tshuab. Los ntawm ntau qhov kev sib tw ntawm dov, lub billet yog txo mus rau nruab nrab thickness. Nyob rau theem no, kev nthuav dav dov lossis shaping dov kuj tseem yuav ua tau raws li qhov xav tau los kho qhov dav thiab cov duab ntawm lub billet kom ze rau qhov loj me ntawm cov khoom kawg . 3. Fine dov: Tom qab qhov nruab nrab billet undergoes lub taub hau thiab tus Tsov tus tw txiav, nws nkag mus rau hauv multi- sawv ntsug zoo dov unit, xws li 4 2} yob 7 {{2} rolling. Cov txheej txheem dov zoo siv siab - ceev dov thiab tswj cov nqi txo kom txo tau cov khoom mus rau qhov kawg tuab. Nyob rau tib lub sijhawm, lub phaj zoo raug kaw- lub voj voog tswj tshuab yog siv los xyuas kom meej tias qhov tseeb qhov loj ntawm titanium phaj ua tau raws li cov txheej txheem siab thiab ua tau raws li cov kev cai nruj ntawm cov ntawv thov sib txawv rau daim hlau titanium . 4. Cua txias thiab winding: titanium coil tom qab zoo dov yog ceev cua txias los ntawm lub tshuab cua txias. Cov txheej txheem cua txias no yuav tsum tau hloov pauv hloov pauv raws li qib sib txawv ntawm cov khoom siv titanium thiab qhov kawg dov kub kom ua tau zoo ntawm cov khoom siv. Tom qab txias, titanium coil raug mob rau hauv ib lub yob los ntawm lub tshuab winding. Cov khoom kawg kuj tseem yuav xav tau kev ua haujlwm tom ntej xws li kev ntim khoom, kos npe, thiab lwm yam, rau kev khaws cia, kev thauj mus los, thiab siv.
Zog-txuag qhov zoo ntawm cov txheej txheem kub dov: Thaum lub sij hawm kub dov txheej txheem, titanium nthuav tawm cov khoom siv yas zoo heev, tsis muaj deformation tsis kam thiab tsis muaj qhov tshwm sim ntawm kev ua kom tawv tawv. Qhov no ua rau txo qis lub zog xav tau rau cov hlau deformation, yog li ua tiav qib kev siv hluav taws xob qis dua . 2. Kev ua haujlwm siab ntau lawm: Kub dov feem ntau siv cov khoom siv loj thiab txo qhov sib piv loj rau dov, ua rau cov khoom siv nrawm nrawm thiab cov zis siab, tsim kom muaj kev txaus siab rau loj - teev ntau lawm thiab ua tau raws li cov phaj loj - Kev ua kom zoo ntawm cov khoom siv microstructure: Los ntawm cov txheej txheem kub dov, raws li - nrum microstructure tuaj yeem hloov mus rau hauv cov txheej txheem microstructure. Qhov kev hloov pauv microstructure no txhim kho cov khoom siv plasticity, txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm titanium phaj . 4. Anisotropic cov khoom: Vim yog cov yam ntxwv ntawm cov txheej txheem dov, cov khoom ntawm cov ntawv dov muaj anisotropy. Ntawm ib sab tes, muaj qhov sib txawv tseem ceeb ntawm cov khoom raws li cov longitudinal, transverse, thiab siab cov lus qhia ntawm cov khoom; Ntawm qhov tod tes, muaj deformation textures thiab recrystallization textures, uas ua rau pom tseeb kev taw qhia sib txawv hauv kev ua haujlwm.
Cov txheej txheem kub dov ntawm titanium daim hlau, raws li cov thev naus laus zis thev naus laus zis rau kev ua haujlwm siab - cov ntaub ntawv hlau kawg, muaj nws cov txiaj ntsig tseem ceeb hauv kev ua tiav kev ua kom zoo ntawm titanium alloy qauv thiab kev ua tau zoo los ntawm kev tswj qhov kub thiab txias (850 - 950℃) thiab ntau dhau ntawm dov. Tam sim no, cov thev naus laus zis no tau kov yeej kev lag luam tsis muaj zog xws li ± 5% hloov pauv hauv dov quab yuam thiab ± 0.1 hli hauv phaj siab kam rau ua. Txawm li cas los xij, nyob rau hauv kev teb rau qhov kev thov ceev hauv thaj chaw aerospace kom muaj zog dua thiab toughness piv ntawm cov alloys xws li TA15 thiab TC4, cov txheej txheem kub dov ntawm titanium daim hlau tseem xav tau kev nruam ntej thiab tshawb nrhiav cov txheej txheem tshiab thiab cov txheej txheem thev naus laus zis txhawm rau txhim kho kev ua tau zoo thiab zoo ntawm titanium daim hlau thiab nthuav lawv daim ntawv thov.
