Cobalt Alloy Casting

K640 yog ib qho kev daws teeb meem-lub zog thiab carbide-zog cobalt-raws li casting superalloy, thiab nws lub zog theem qis dua me ntsis ntawm cov nickel-based casting superalloy K401. Cobalt alloy casting muaj kev ua haujlwm zoo thermal qaug zog, oxidation tsis kam thiab corrosion kuj ntawm qhov kub thiab txias, yog li nws yog qhov tshwj xeeb tshaj yog tsim rau cov roj turbine qhia cov hniav ua haujlwm hauv qab 1000 degree. Nyob rau hauv lub sij hawm ntev kev laus ntawm 800 degree, tus qauv yog ruaj khov, qhov kev ua tau zoo ntawm casting yog zoo, thiab nws yuav raug cam khwb cia rau hauv qhov chaw xws li hollow hniav nrog complex duab. Txawm li cas los xij, vim qhov tsis txaus ntawm cov peev txheej cobalt, daim ntawv thov raug txwv.

Tom qab ntau tshaj kaum xyoo los nag, Qinhuangdao Zhongwei Precision Machinery Co., Ltd. muaj kev nplua nuj nyob rau hauv zus tau tej cov cobalt alloys, nickel alloys, superalloys thiab lwm yam castings. Peb cia siab tias cov neeg tsim khoom los ntawm thoob plaws lub ntiaj teb tuaj yeem sab laj thiab sib tham ua lag luam.

Cobalt Alloy Casting Txheej Txheem

K640 technical standard

YB/T 5248-1993 "Casting Superalloy Master Alloy"

K640 Tshuaj muaj pes tsawg leeg

1.K640 kev kho cua sov: cov hlau yog siv nyob rau hauv lub xeev li-cam khwb cia.

2. K640 ntau yam, specifications thiab muab: round bar-zoo li tus tswv alloy ingots. As-cast khoom.

3. K640 smelting thiab casting txheej txheem:

Tus tswv alloy yog smelted nyob rau hauv lub tshuab nqus tsev induction rauv, lub refining kub yog 1580 degree, thiab lub pouring kub yog 1460 degree. Argon roj nrog lub siab ntawm 5000-7000Pa yuav tsum tau qhia thaum lub sij hawm nchuav. Tus tswv alloy tseem tuaj yeem smelted hauv hluav taws xob cais qhov cub. Lub tshuab nqus tsev induction rauv lossis tsis-nqus arc reversing rauv hnyav rauv, qhov kub thiab txias yog 1450-1490 degree, thiab cov cua kub ntawm lub plhaub pwm yog qis dua 850 degree. Thaum lub tshuab nqus tsev casting, argon roj nrog lub siab ntawm 5000-7000Pa kuj yuav tsum tau.

4. K640 daim ntawv thov txheej txheem cej luam thiab cov kev cai tshwj xeeb:

Cov alloy tau siv nyob rau hauv lub tshuab aero-engine raws li kev qhia vane. Lub X40 alloy zoo ib yam li no alloy yog dav siv nyob rau hauv txawv teb chaws aviation dav hlau xyaw, xws li: JT3D, JT9D, JT4A, CFM56 thiab SpeyMK202 cav turbine hniav los yog qhia vanes yog ua los ntawm no alloy.

5. K640 txheej txheem kev ua tau zoo thiab cov kev xav tau:

(1) Formability

Qhov kev ua tau zoo ntawm kev ua haujlwm yog zoo dua li ntawm austenitic stainless hlau, thiab nws tuaj yeem muab pov rau hauv nyias-walled hollow hniav thiab lwm qhov chaw los ntawm peev casting.

(2) Kev ua haujlwm vuam

1) Nws muaj kev ua haujlwm zoo vuam nrog inert gas arc vuam. Oxyacetylene vuam feem ntau tsis siv. K640 alloy nws tus kheej tuaj yeem txuas nrog K640 electrode, thiab kev sib txuas nrog lwm cov alloys yuav tsum nyiam siv HastelloyW alloy electrode. Ua ntej vuam qhov loj, nws yuav tsum tau preheat nyob rau hauv 371-427 degree kom tsis txhob tawg tom qab vuam. V-shaped kev sib txuas feem ntau yog siv, tab sis U-shaped kev sib txuas tau pom zoo rau qhov chaw uas muaj kev ntxhov siab.

2) Thaum vuam nyob rau hauv ib qho chaw tiv thaiv, nws raug nquahu kom tsis txhob muaj qhov loj me ntawm qhov vuam ntawm ob sab, thiab cov tooj liab yuav tsum tsis txhob siv los ua cov phaj hauv ob sab phlu.

3) Thaum siv DC cais vuam, cov khoom siv kho tshuab zoo tuaj yeem tau txais. Txhawm rau tiv thaiv kev tawg, nws raug nquahu kom siv lub inclined hluav taws xob arc rov qab-thiab-tawm saum npoo.

(3) Cov txheej txheem kev kho cua sov ntawm cov khoom siv: Cov khoom siv hauv lub xeev li-casting.
