Khoom Description
I. Khoom Zoo
1. Elongation Ntau dua lossis sib npaug li 25% (lub xeev annealed), ua kom muaj kev ua haujlwm theem nrab xws li khoov, stamping, thiab vuam los ua cov khoom sib txuas (xws li, titanium phaj fins rau cov khoom siv hluav taws xob).
2. Superior low -kub kev ua haujlwm: Ua kom muaj zog zoo hauv cov dej hydrogen ib puag ncig mus rau -253℃yam tsis muaj qhov kub thiab txias, haum rau kev tsim cov hlab ntsha cryogenic.
3. Tsis yog-sib nqus: Haum rau cov khoom siv hlau nplaum sib nqus hauv cov tub rog thiab cov khoom siv hluav taws xob, tiv thaiv kev cuam tshuam nrog kev ntsuas qhov tseeb.
4. High-kub oxidation kuj: Qhia tawm tsis tshua muaj oxidation tus nqi nyob rau hauv atmospheric ib puag ncig qis dua 500℃thiab muaj peev xwm tiv taus luv luv- lub sij hawm raug rau 600 degree, ua rau nws haum rau nruab nrab - mus rau - kub tsis tshua muaj kub - cov khoom tiv taus.
II. Cov ntsiab lus tseem ceeb rau Ntshiab Titanium Phaj Rolling
1. Cov txheej txheem cua sov: Kev Tiv Thaiv Oxidation + Phase Control Zone (Core Yam Yuav Tsum Tau Paub)
Kub Kub: Rau kub- dov GR1 / GR2, pom zoo cua sov kub yog 780-820 degree. Rau TA3 nrog lub zog me ntsis, qhov kub yuav nce mus rau 800-850 degree.
Rolling Txias: Yob nyob rau hauv chav tsev kub (tsis muaj cua sov yuav tsum tau). Txawm li cas los xij, cov phaj tuab yuav tsum tau nruab nrab annealing (600-700 degree, tuav rau 1-2 teev) txhawm rau txhawm rau ua haujlwm hnyav ua ntej txias dov.
Tiv thaiv huab cua: cua sov yuav tsum tau ua nyob rau hauv lub tshuab nqus tsev vacuum furnaces los yog argon-shielded furnaces los tiv thaiv huab cua. Tuav Lub Sijhawm: Kho raws li phaj thickness (20-50 hli daim hlau yuav tsum tau 2-4 teev tuav lub sijhawm) los xyuas kom meej qhov kub thiab txias tsis sib xws thiab tiv thaiv cov cua sov hauv cheeb tsam lossis cua sov tsis txaus.
2. Rolling txheej txheem tswj: ceev + khoom siv (Txiav txim siab daim ntawv khoom)
Rolling Ceev:
Kub Rolling: Tsawg- dov ceev (0.5–1.5 m / s) txhawm rau tiv thaiv cov cua sov hauv cheeb tsam (dhau ntawm theem cheeb tsam) tshwm sim los ntawm kev sib txhuam cua sov, uas ua rau cov pob zeb ntxhib tsim.
Txias dov: Nruab nrab- ceev dov (1–2 m / s) kom txo tau cov nqi ua hauj lwm hardening thiab tiv thaiv ntug tawg hauv daim ntawv.
Cov Khoom Siv Khoom Siv: Rolls yuav tsum siv hnav- cov khoom siv tiv taus (xws li, Cr12MoV) nrog polished nto (surface roughness Ra tsawg dua lossis sib npaug li 0.8 μm) los tiv thaiv khawb ntawm titanium phaj nto. Tshwj xeeb txias lubricants (piv txwv li, cov roj siab siab uas muaj molybdenum lossis tungsten) yuav tsum tau txau thaum lub sij hawm dov kom txo cov kev sib txhuam coefficients thaum tib lub sijhawm txias cov yob thiab daim hlau.
3. Kev ua kom txias thiab ua haujlwm tom qab: Ua kom muaj qhov tseeb qhov tseeb + kev ua haujlwm ruaj khov
Txoj kev ua kom txias:
Tom qab kub dov: Cua txias los yog yuam cua txias (tsis txhob tso dej txias kom tsis txhob deformation lossis tawg vim qhov kub sib txawv). Tswj qhov ntsuas cua txias ntawm 5-10℃/ min kom ntseeg tau tias microstructure tsis sib xws (zoo, zoo ib yam).
Tom qab txias dov: Lub ntuj txias kom tsis txhob muaj kev ntxhov siab sab hauv los ntawm kev ua kom txias sai.
Ncej -Kev ua haujlwm:
Pickling: Tshem tawm cov nplais saum npoo, xyuas kom tsis muaj qhov seem seem (nto zoo li silvery dawb tom qab pickling).
Annealing: Txias-cov khoom dov yuav tsum tau ua tiav annealing (600-650 degree, nqus tsev tuav rau 2 teev) kom tshem tawm cov kev ntxhov siab sab hauv thiab rov ua kom cov ductility (post-annealing tensile zog Ntau dua lossis sib npaug rau 370 MPa, elongation Ntau dua lossis sib npaug li 25%).
Kev Ncaj Ncees: Siv lub tshuab rau cov menyuam ncaj (qhov tseeb ± 0.5 mm / m) los kho cov ntawv flatness (flatness Tsawg dua lossis sib npaug li 3 mm / m) thiab tiv thaiv kev sib tsoo.
III. Summary of Key Application Scenario Comparison
Corrosion Resistance Priority: Kev ua tshuaj lom neeg, offshore engineering → Xaiv kub -rolled ntawv (cov ntawv tuab, tus nqi qis, ua tau raws li qhov yuav tsum tau muaj corrosion);
Precision thiab Surface Quality Priority: Aerospace, kho mob, electronics → Xaiv txias -rolled ntawv (nyias specifications, siab precision, du nto);
Kev Ua Haujlwm Tshwj Xeeb: Anti-slip → Patterned txias-rolled ntawv; Biocompatibility → Polished txias -rolled ntawv; Tsawg-Tsuas Kub Ib puag ncig → Kub- dov / Cold- cov ntawv dov (cov titanium ntshiab qhia tau zoo heev qis- kub toughness yam tsis tas yuav tsum tau kho tshwj xeeb).
