GR1 titanium phaj ua
Nyob rau hauv high -}}} titanium alloy ta1) tau ua cov ntaub ntawv titanium, thiab lwm cov chaw tsim khoom, thiab lwm yam khoom siv corrosium ntau tshaj, biocompatibility, thiab lub teeb yuag. Nws cov kev ua siv metallurgical, kev kho cua sov, thiab precision Kev thev naus laus zis, nrog txhua kauj ruam uas yuav tsum tau tswj nruj kom ua kom cov kev ua tau zoo.
Raw Khoom Npaj
Kev ua cov gr1 titanium phaj pib nrog kev npaj ntawm siab- purity titanium. Titanium Tetrachloride yog txo cov qib KRoll Cov lus no yog ces crushed, tshuaj ntsuam, thiab sib xyaw kom ntseeg tau tias kev sib xyaw ua ke. Tom qab, lub tshuab nqus tsev muaj cov tshuab hluav taws xob (var) yog siv los nias lub spongium tendodode:
Pressing txheej txheem: hauv qab lub siab ntawm 300-500 mpa, titanium daim txhuam cev classer yog cov kab zauv ntawm 500-800 hli thiab qhov siab ntawm 1.2-1.5 m. Qhov ceev ceev yuav tsum tau tswj hwm ntawm 1.8-2.0 g / cm³ los tiv thaiv kev sib tsoo thaum lub sijhawm yaj.
Vuam kev sib dhos: ntau lub sib dhos elardrode tau txuas los ntawm Plasma Vuam los ua ib qho 3-5 m melting electrode. Weld sib koom tes yog ultrasonically soj ntsuam kom ntseeg tau qhov tsis xws luag xws li pores thiab nrib pleb.
Lub tshuab nqus dej: Hauv cov tshuab hluav taws xob, cov electrodes tau meled nyob rau hauv lub tshuab nqus dej 10-5 feeb los ua rau segaration, feem ntau 3-5 zaug ua rau hauv titanium ingot nrog ib qho kev sib txuam. Cov ntsiab lus oxygen yuav tsum nruj me ntsis tswj tau qis dua 0.08% kom tiv thaiv emgrittlement.
Kub Rolling
Titanium Ingots yog tsim rau hauv thawj slabs los ntawm cov txheej txheem kub kub. Tus txheej txheem no yuav tsum muaj kev sib npaug ntawm qhov kub thiab txias, deformation, thiab txias tus nqi:
Cov theem cua sov: Titanium Ingots yog rhuab rau 950- 1000℃hauv cov roj rauv taws. Lub sijhawm uas tau tuav tau suav raws li cov ingot thickness (2 teev toj ib 100mm), ua kom muaj kev sib txuam kub thiab txias ntawm ± 5 degree.
Kev ntxhib xoo hluav taws xob: Ib qho ob {-}}}}}}}} ™ ing ing ingots los ntawm 300mm tuab rau 50-80mm tuab slabs. Qhov txo qis rau ib daim Pass yog tswj ntawm 15-20 hli kom tsis txhob muaj ntug kev tawg.
FINISHING DOV: Tom qab rov ua kom tiav 900 {}} 9} {} {{{{{{} {{} {{} - ± 0.5mm. Dov ceev ceev mus txog 5-8m / s. Emulsion txias yog qhov yuav tsum tau tswj hwm qhov kawg ntawm kev kub kawg ntawm 750-800℃los tiv thaiv cov nplej zom. In-kab waresening: 11-yob wires zoo nkauj yog siv los ua kom ncaj lub phaj kub thiab tswj hwm ib qho tsawg dua lossis sib npaug ntawm 2 hli / m.
Cold Cold Tiav
Qhov kub - rolled phaj tawg cov khaub thuas dov mus txuas ntxiv txhim kho qhov chaw roughness thiab tuab qhov tseeb:
Pickling thiab Descaling: Qhov kub {- nitric acid thiab 1-3% nitrofluoric acid kom tshem tawm cov nplaim oxide nplai (kwv yees li 0.1-0.3mm tuab). Kev ua haujlwm nrawm yog tswj tau ntawm 1-2m / min kom tiv thaiv ntau yam xeb.
Txias rolling deformation: a rau -}}}}}}}}}}}}}}}}}}}}}}} ™ awing tag nrho deformation ntawm 30-50%. Qhov txo ib daim Pass yog tswj ntawm 0.1-0.5mm, nrog lub zog dov ntawm 1000-1500 tons. Qhov kawg tuab tho kev puas tsuaj yog ± 0.05mm.
Annealing: Lub txias txias - rolled phaj yog muaj nyob rau hauv lub tshuab nqus tsev soap ntawm 700-750℃rau kev tshem tawm cov haujlwm ua haujlwm thiab rov ua haujlwm. Tom qab annaling, lub hardness yog txo rau HV150-180, thiab lub elongation yog nce rau ntau dua 25%.
Cov polishing: cov neeg kho tshuab polishing lossis electrolytic polishing yog siv los txo cov npoo av hauv qab no thiab lwm yam kev siv.
Tshaj tawm - kev thiab kuaj
Lub tiav lawm titanium daim phiaj yauv rau hauv posts - kev ua thiab kev sim cov txheej txheem:
Txiav thiab slitting: laser lossis dej dav hlau txiav yog siv los txiav cov paib titanium rau hauv cov qhov ntau thiab tsawg. Kev txiav npoo yog chamfed (R0.5-1mm) kom tsis txhob muaj kev ntxhov siab.
Tsis - Kev sim ua: Ultrasonic Kev Ntsuas (xws li siv los tshawb xyuas sab hauv (xws li suav nrog thiab tawg. Eddy kev sim tam sim no (thiab) yog siv los tshuaj ntsuam kom tawg ntawm qhov nrawm nrawm txog 10m / min. Kev sim tshuaj ntsuam: Tensile kuaj raws li ASTM E8 yielded tensile lub zog ntau dua los yog sib npaug rau 170 MPa, thiab elongation ntau dua los yog sib npaug rau 24%. Corrosion ntsuas raws li ASTM G48 pom tias muaj tus nqi corrosion tsawg dua lossis sib npaug rau 0.001 mm / xyoo hauv 3.5% nacl daws.
Ntim thiab kev tiv thaiv: cov paib titanium tau coated nrog anti {{vapor begase anti - xeb zaj duab xis. Cov crates ntoo yog ntim nrog cov pab pawg ua npuas dej kom tiv thaiv kev thauj mus los.
Los ntawm titanium daim txhuam cev kom high {{prec precision titensle yog kev ua kom me me ua rau kev kub ntxhov, deformation, thiab purity. Qhov ua tau zoo ntawm txhua tus txheej txheem parameter lub sib sib zog nqus ntawm cov ntaub ntawv science thiab thaum kawg pab txhawb rau cov hlau uas "
