GR2 Titanium Alloy Forged Block

I. Khoom Taw Qhia

Titanium alloy forged blocks yog square forgings ua los ntawm titanium thiab titanium alloys los ntawm cov txheej txheem forging. Lawv muaj cov txiaj ntsig zoo ntawm titanium alloys xws li lub zog siab, lub teeb yuag, corrosion kuj, thiab biocompatibility. Tsis tas li ntawd, tom qab forging, lawv muaj cov qauv ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom cov qauv tsim thiab cov khoom siv kho tshuab zoo sib xws, ua rau lawv cov khoom siv tseem ceeb hauv high Titanium blocks (forged thiab dov billets), raws li cov khoom tseem ceeb rau hauv ob sab phlu daim hlau ntawm cov tshuaj reactors thiab cov load- bearing bases sib sib zog nqus- hiav txwv cov khoom, tau dhau los ua ib tug irreplaceable strategic khoom nyob rau hauv huab ib puag ncig vim lawv tag nrho - nruab nrab corrosion kuj (acid/alkali/hydrogen ion), ultra- siab zog thiab toughness sib piv (compressive zog Ntau dua los yog sib npaug rau 800MPa), thiab loj- qhov loj me me sib xyaw ua kom zoo. Piv nrog rau cov tsoos Hastelloy, titanium blocks muaj 8-fold ntev lifespan nyob rau hauv boiling hydrochloric acid thiab tuaj yeem txo qhov hnyav los ntawm 40%.

II. Txheej txheem ntau lawm

Lub hom phiaj tseem ceeb ntawm titanium alloy forging yog txhawm rau tshem tawm qhov tsis xws li porosity thiab kev sib cais hauv cov khoom siv los ntawm "kev ua haujlwm kub + yas deformation", txhim kho cov qauv nplej, thiab txhim kho lub zog, tawv thiab qhov tseeb ntawm cov forgings. Txoj kev ua tiav cov txheej txheem yuav tsum nruj tswj qhov kub thiab txias, deformation tus nqi thiab tus nqi cua txias.

1. Raw khoom npaj thiab pretreatment: Xaiv titanium ingots ntawm cov qib sib xws raws li qhov kev thov scenario. Tshem tawm cov nplais oxide los ntawm qhov chaw ntawm cov titanium ingots (los ntawm kev sib tsoo los yog kua qaub ntxuav, nrog rau cov kua qaub ntxuav cov mis ntawm HF: HNO₃: H₂O=1: 3: 16) los tiv thaiv cov nplai oxide los ntawm kev nias rau hauv lub forging thaum lub sij hawm forging thiab ua rau tsis xws luag. Nyob rau tib lub sijhawm, titanium ingot yog raug rau homogenization annealing (ntawm qhov kub ntawm 900 txog 950 degree, tuav rau 2 mus rau 4 teev) txhawm rau tshem tawm cov kev sib cais sab hauv ntawm cov ingot.

2. Cov txheej txheem cua sov: Titanium alloy forging yog rhiab rau qhov kub thiab txias thiab yuav tsum tau nruj me ntsis tswj nyob ib ncig ntawm lub "hloov kub" (T ). Lub tshuab nqus tsev los yog cov roj inert{2}}cov cua sov tiv thaiv (argon cua) yuav tsum tau siv los tiv thaiv titanium alloys los ntawm oxidizing thiab nqus hydrogen ntawm qhov kub thiab txias (cov ntsiab lus hydrogen ntau dhau tuaj yeem ua rau "hydrogen embrittlement", thiab H yuav tsum tau tswj kom tsawg dua lossis sib npaug li 0.015%). Cov cua kub yuav tsum tsawg dua lossis sib npaug li 150℃/ h kom tsis txhob muaj kev ntxhov siab thermal tawg. Lub sij hawm tuav yog xam raws li qhov tuab ntawm titanium ingot (1.5 mus rau 2.5 feeb / hli) kom ntseeg tau tias qhov kub thiab txias nkag.

3. Forging ua: Kev cai square pwm yog siv. Cov cua kub titanium billets tau muab tso rau hauv cov pwm kab noj hniav thiab tsim nyob rau hauv ib los yog ntau yam dhau los ntawm ib tug xovxwm (tonnage Ntau tshaj los yog sib npaug rau 3000t). Cov pwm yuav tsum tau preheated rau 300-400℃kom txo tau qhov kev pheej hmoo ntawm pwm coj thiab forging tawg. Tom qab tuag forging, lub microstructure ntawm forged ib feem yog zoo li qub, thiab tom qab machining nyiaj yuav raug txo los ntawm 30% mus rau 50%.

4. Cov txheej txheem kev kho cua sov: Kev kho mob annealing (tus txheej txheem tseem ceeb): tshem tawm cov kev ntxhov siab sab hauv, txhim kho microstructure, thiab txhim kho plasticity.

5. Machining thiab xov: Cov nplai oxide thiab nyiaj ntau tshaj ntawm qhov chaw forging raug tshem tawm los ntawm cov tshuab milling thiab cov phiaj, thiab cov forging yog thawj zaug machined rau hauv cov duab square (tawm ntawm qhov nyiaj ntawm 1 mus rau 3 hli). Milling thiab sib tsoo yog ua los ntawm kev siv lub tshuab CNC machining chaw kom paub meej qhov tseeb ntawm qhov square. Tshem cov burrs ntawm cov ces kaum thiab cov npoo, thiab siv ultrasonic tu kom tshem tawm cov roj stains thiab cov khib nyiab hlau.

Ⅲ. Daim ntawv thov

1. Chemical Engineering thiab Marine Engineering: Sib sib zog nqus- cov khoom siv hauv hiav txwv thiab lub cev valve, cov tshuaj reactor liners thiab electrodes

2. Lub zog tshiab: Sab hauv hauv ob sab phlu ntawm cov tshuaj tiv thaiv cov hlab ntsha, core shafts ntawm lithium roj teeb cathode rollers

3. Cov thev naus laus zis tshiab: Nuclear fusion reactor diverters, titanium alloy pob qij txha rau submarine optical cables.
