Dab tsi yog Cov Txheej Txheem Tsim Nyog Thiab Machining Technologies Rau Titanium Flange Blocks?

Titanium flangeblocks yog cov tseem ceeb txuas cov khoom siv rau aerospace, petrochemical, dej hiav txwv-engineering thiab high-end khoom. Titanium alloys feature low density, high strength, high‑and‑low‑temperature resistance, corrosion resistance and non‑magnetic properties. Lawv tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev nyob rau hauv cov xwm txheej hnyav xws li muaj zog acid-alkali ib puag ncig, tshuaj ntsev hnyav thiab hloov cov khoom siv siab, ua kom muaj kev sib khi thiab cov kav dej sib txuas ntawm cov khoom siv high-end.

 

 

Titanium flanges feem ntau txais yuav Qib 2 ntshiab titanium thiab Qib 5 titanium alloy ua raws li ASTM B381 thiab ASME B16.5 cov qauv, rau kev siv dav dav corrosion-resistant thiab high-strength load-bearing daim ntaub ntawv feem.

 

Tsis zoo thermal conductivity: Nws thermal conductivity tsuas yog 1/4 ntawm stainless hlau thiab 1/6 ntawm carbon hlau. Txiav kub concentrates nyob rau hauv tej cheeb tsam, uas yooj yim ua rau cov cuab yeej hlawv, workpiece nto burn-in thiab coarse grain lug.

 

Kev ua haujlwm tshuaj lom neeg siab: Thaum kub kub, titanium yooj yim ua rau cov pa oxygen, nitrogen thiab cov khoom siv los ua cov txheej txheem tawv tawv, ua rau lub ntsej muag tsis zoo, qhov sib txawv ntawm qhov sib txawv thiab txawm tias micro-cracks.

 

Kev ua haujlwm hnyav hnyav: Qhov tawv tawv nce siab tom qab cov yas deformation, ua rau kev ua haujlwm thib ob nyuaj thiab ua rau muaj kev ntxhov siab.

Tsawg elastic modulus: Workpiece caij nplooj ntoos hlav-rov qab tshwm sim thaum lub sij hawm txiav, nqa cov kev cov nyom rau kev tswj qhov ntev kam rau ua, flatness ntawm sealing ntsej muag thiab precision ntawm bolt qhov.

 

 

1. Daim ntawv dawb paug

• Forging: Nyiam rau kev lag luam aerospace thiab petrochemical rau kev ua haujlwm siab thiab kev ntseeg siab. Kub-tswj forging ntawm titanium blanks refines nplej thiab tshem tawm qhov tsis xws luag rau superior siab-bearing muaj peev xwm thiab qaug zog kuj. Nws yuav tsum tau tswj qhov kub thiab txias vim qhov nqaim qhov rais qhov rais, nrog rau cov machining nyiaj cia tseg.
• Phaj txiav: Siv rau qhov loj-inch, qis-load corrosion-resistant qhov chaw. Blanking yog ua los ntawm plasma txiav los yog xaim-txiav. Nws muab tus nqi qis thiab lub sijhawm ua haujlwm ceev tab sis kev ua haujlwm tsis zoo-kev coj tus kheej piv nrog forgings.
• Hmoov metallurgy nyob ze-net shaping: Kev sib xyaw txias isostatic nias thiab nqus sintering, cov txheej txheem no ua tiav cov khoom siv siab. However, its density and mechanical properties are moderate, mostly used for lightweight low‑load high‑end civil components.

 

2. Kev kho cua sov Precision

Cov pob zeb muaj qhov cuam tshuam rau deformation thiab tawg. Nqus annealing (lub tshuab nqus tsev kawm qib siab dua lossis sib npaug ntawm 1 × 10⁻³ Pa) tau txais yuav kom tsis txhob oxidation thiab hydrogen nqus. Rau Qib 2: 600-650 degree; rau Qib 5: 700-750 degree. Tuav rau 2-4 teev thiab txias nrog lub qhov cub kom txo tau kev ntxhov siab thiab homogenize nplej. Cov tshuaj kho thiab kev laus tuaj yeem ntxiv rau cov khoom siv muaj zog los txhim kho lub zog thiab tawv.

 

3. Precision Machining

Txais cov cuab yeej coated carbide nrog cov kaum sab xis zoo. Siv cov khoom lag luam tshiab txiav tawm kom tiav machining kom txo tau cov cuab yeej adhesion thiab ua hauj lwm hardening. Ua cov txheej txheej txiav ntawm qhov qis spindle ceev, nruab nrab tus nqi pub thiab me me txiav qhov tob kom tso tawm kev ntxhov siab. Siv cov cua txias txias nrog titanium tshwj xeeb txiav kua; qhuav txiav yog txwv tsis pub. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tseeb ntawm kev sib khi lub ntsej muag, lub qhov ntsia hlau thiab lub ntsej muag kawg kom tiv thaiv kom tsis txhob yaig thiab lav geometric kam rau ua.

 

4. Kev kho deg

• Pickling thiab passivation: Tshem tawm cov roj paug thiab oxide nplai thiab tsim cov yeeb yaj kiab passivation rau acid-alkali tsis kam, haum rau kev lag luam tshuaj lom neeg thiab hydrometallurgical.
• Anodizing: Tsim cov oxide zaj duab xis rau kev txhim kho hnav tsis kam thiab ntsev-txhaj tshuaj tiv thaiv, muaj feem xyuam rau thaj chaw hauv hiav txwv thiab sab nraum zoov.
• Precision polishing: Daim iav polishing rau flanges tshem tawm cov cuab yeej cim thiab txhim kho kev ua haujlwm siab sealing.

 

 

1.Anti-deformation tswj tshuab

Titanium alloys zoo li deform los ntawm lub caij nplooj ntoos hlav-rov qab. Sib cais roughing thiab xov ua haujlwm. Tshem tawm cov nyiaj ua haujlwm tom qab roughing thiab tuav lub workpiece kom tso cov kev ntxhov siab sab hauv. Ua ke nrog symmetrical txheej txiav kom txwv workpiece warping thiab stabilize qhov tseeb.

 

2.Tool life extension thiab txiav stability technology

Siv cov cuab yeej coated carbide ua ke nrog tsawg kawg kom muaj nuj nqis lubrication kom txo tau hnav. Standardize cov cuab yeej hloov rau kev ua tiav-txiav kom tsis txhob dulling npoo thiab xyuas kom meej meej nyob rau hauv ntau lawm.

 

3.Accurate metallographic qauv tswj tshuab

Kev txawj ntse ntsuas kub ntsuas cov txheej txheem tsis raug rau forging thiab kev kho cua sov kom txo tau qhov tsis xws luag ntawm metallurgical, refine thiab homogenize nplej, thiab lav txhua yam khoom xws li lub zog, toughness thiab qaug zog.

 

 

1.Dimensional raug

Ntsuas sab nraud, thickness, flatness ntawm sealing lub ntsej muag, txoj hauj lwm thiab perpendicularity ntawm bolt qhov siv kev sib koom tes ntsuas tshuab, micrometers thiab feeler gauges los xyuas kom meej tsim nyog kam rau ua.

 

2.Qhov zoo

Tshawb xyuas cov kab nrib pleb, khawb, oxidation thiab lwm yam tsis xws luag los ntawm kev soj ntsuam qhov muag ntxiv rau cov magnifiers. Ntsuas qhov roughness ntawm sealing ntsej muag nrog

roughness testers.

 

3.Internal non-destructive kuaj

Ua kev kuaj ultrasonic thiab radiographic txhawm rau txhawm rau txhawm rau txhawm rau hauv qhov tsis xws luag xws li pores, suav nrog thiab micro-cracks.

 

4.Mechanical zog

Ua cov qauv ntsuas suav nrog kev ntsuas tensile, ntsuas qhov tawv, ntsuas qhov cuam tshuam thiab ntsuas kev qaug zog kom paub tseeb lub zog, toughness thiab tiv thaiv kev qaug zog.
