TA2 Titanium Alloy Melting Txheej Txheem Ntsuas Qhov tob

Cov khoom siv melting thiab cov txheej txheem tseem ceeb
Cov txheej txheem melting ntawm TA2 titanium alloy yog qhov zoo heev, uas feem ntau tso siab rau ob yam khoom loj: lub tshuab nqus tsev arc rauv thiab lub tshuab nqus tsev induction. Lub tshuab nqus tsev arc rauv, nrog nws cov yam ntxwv kub ntawm lub arc, tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev tsim cov purity siab titanium alloys. Lub melting kub yog stabilized nyob ib ncig ntawm 1600 degree, uas xyuas kom meej tias cov hlau yog melted zoo kawg nkaus nyob rau hauv ib tug ntshiab lub tshuab nqus tsev ib puag ncig. Lub tshuab nqus tsev induction rauv, ntawm qhov tod tes, nrog nws yooj yim ntawm electromagnetic induction cua sov, qhia tau hais tias zoo heev nyob rau hauv loj ntau lawm thiab zoo tswj ntawm alloy muaj pes tsawg leeg, thiab nws melting kub yuav siab li 1650 degree.

Fine melting txheej txheem
Kev xaiv cov khoom siv raw: High purity titanium sponge thiab precisely proportioned alloying ntsiab raug xaiv, ntxuav thiab qhuav nruj me ntsis rau nteg lub hauv paus rau ib tug zoo alloying.
Precise Furnace Loading: Xyuas kom cov khoom sib npaug sib npaug hauv lub cub tawg kom ntseeg tau tias qhov sib xws ntawm cov alloy muaj pes tsawg leeg.
Kev tswj qhov kub thiab txias: Nyob rau hauv lub tshuab nqus tsev, qhov kub thiab txias yog tswj los ntawm 1600 degree thiab 1650 degree kom ntseeg tau tias qhov zoo tshaj plaws melting ntawm titanium alloy thiab tsis txhob overheating los yog overcooling.
Sib sib zog nqus refining: Nqus kho thiab electromagnetic stirring yog siv los tshem tawm impurities thiab gases nyob rau hauv lub yaj thiab txhim khu lub purity ntawm cov hlau.
Nqus Casting: Casting yog nqa tawm nyob rau hauv ib qho chaw nqus tsev vacuum los tiv thaiv kev kis kab mob thib ob thiab xyuas kom meej qhov zoo ntawm cov hlau tiav.
Kev Tiv Thaiv Kev Nyuaj Siab
Kev tswj qhov kub thiab txias: lub melting kub yuav tsum nruj me ntsis tswj nyob rau hauv qhov zoo tshaj plaws cheeb tsam kom lub zoo meej alloy lub koom haum thiab kev ua tau zoo.
Lub tshuab nqus tsev siab: Cov txheej txheem melting yuav tsum muaj lub tshuab nqus tsev siab kom txo qis kev cuam tshuam ntawm cov pa roj impurities.
Lub sij hawm tswj: tsim nyog tswj lub sij hawm melting kom tsis txhob oxidation ntau dhau los yog roj nqus ntawm titanium alloy.
TA2 titanium alloy high-temperature kuj tau tshwm sim.
Cov kev ua haujlwm zoo heev
TA2 titanium alloy muaj kev ua tau zoo hauv kev ua haujlwm ntawm qhov kub thiab txias, nws lub zog tensile thiab elongation nyob twj ywm siab ntawm chav tsev kub txog 500 degree, raws li hauv qab no:
Chav tsev kub (25 degree): tensile zog 485 MPa, elongation 20%.
300 degree: tensile zog me ntsis txo mus rau 440 MPa, elongation 18%.
400 degree: tensile lub zog tseem poob mus rau 415 MPa, elongation 16%.
500 degree: tensile lub zog tseem khaws cia ntawm 370 MPa, elongation 14%, uas qhia tau hais tias kev ua haujlwm kub zoo heev.
Cov teb siv dav heev
TA2 titanium alloy yog dav siv nyob rau hauv aerospace, tshuaj thiab marine engineering vim nws zoo heev kub tsis kam. Nyob rau hauv aerospace teb, nws yog feem ntau siv raws li aircraft engine Cheebtsam thiab high-temperature structural qhov chaw; nyob rau hauv cov tshuaj, nws yog siv los tsim high-temperature corrosion-resistant reactors thiab pipelines; nyob rau hauv lub tshav pob ntawm dej hiav txwv engineering, nws yog ib qho tseem ceeb ntawm cov khoom siv rau kev sib sib zog nqus dej hiav txwv probes thiab submarine roj thiab roj extraction khoom.
Kev sib piv kev ua haujlwm thiab cov ntawv sau
Piv nrog TA6V, TC4 thiab lwm yam titanium alloys, TA2 muaj qhov ua tau zoo ntawm qhov kub ntawm 500 degree. Txawm li cas los xij, TA2 yog qhov ua rau oxidization nyob rau hauv qhov kub thiab txias tshaj 600 degree, thiab kev tiv thaiv yuav tsum tau ua raws li. Tsis tas li ntawd, machining nyob rau hauv qhov kub thiab txias ib puag ncig yuav tsum tau ua tib zoo ua haujlwm kom tsis txhob muaj cov khoom puas.
