Test txheej txheem ntawm lub tshuab nqus tsev kho cua sov khoom

Test txheej txheem ntawm lub tshuab nqus tsev kho cua sov khoom

(1) Ob lub qhov rooj sib txawv, cov kiv cua zoo li ib tus neeg khiav thiab cov ceg khiav, tau siv rau kev sim, thiab phab ntsa tuab ntawm cov qauv yog 5 hli.

(2) Thaum tshav kub kub ntawm aluminium alloy ingot mus rau lub xeev ib nrab (60 feem pua ​​​​ntawm cov khoom), muab tso rau hauv lub siab chamber ntawm lub tshuab tuag-casting, thiab txhaj tshuaj molding.

(3) Txiav cov qauv rau kev ntsuas lub zog tensile, elongation test thiab microstructure tsom xam.

Lub tshuab nqus tsev kub kho cov cuab yeej kuaj cov khoom siv

Buhler txhaj tshuaj tswj tuag casting tshuab (H-250 SC); Alpha 1 tib coil induction cua sov lub cev; Foudarex lub tshuab nqus tsev vacuum.

Lub tshuab nqus tsev kho cua sov cov cuab yeej ntxuav cov kua impregnating ntawm cov khoom hauv lub sijhawm

Nco ntsoov ntxuav tawm cov kua impregnating ntawm cov khoom hauv lub sijhawm. Thaum lub sij hawm, nws yuav agglomerate rau saum npoo. Infiltration yog zoo heev rau pores nyob rau hauv txhuas tuag castings. Peb yuav cov khoom siv hauv Ningbo rau kev siv, uas tuaj yeem ua kom tsis txhob muaj cua nkag hauv peb cov khoom siv txhuas tuag casting, vim tias peb cov khoom siv rau lub sijhawm muaj kev kub ntxhov. Tsis leaking kiag li. Yog tias cov khoom yuav tsum tau muaj siab, nws tseem tsim nyog. Nws feem ntau tsis siv rau lub sijhawm muaj kev kub ntxhov, thiab tsis tas yuav muaj qhov no, tsuav yog koj siv koj lub hlwb ntawm lub tshuab tuag-casting thiab ua haujlwm zoo.

Lub tshuab nqus tsev kub kho cov cuab yeej infiltration hais txog:

⑴ Muab cov khoom tso rau hauv lub tank impregnation.

⑵ Kev kho lub tshuab nqus tsev: Pib lub tshuab nqus tsev twj tso kua mis, lub tshuab nqus tsev siab siab tshaj -0.09MPa, siv lub tshuab nqus tsev kom tshem tawm cov huab cua (lossis dej, roj, thiab lwm yam) hauv micropores lossis tawg ntawm qhov chaw, thiab lub sijhawm nqus tsev yog 15 feeb.

(3) Siv lub tshuab nqus tsev nqus cov kua nplaum rau hauv lub tank impregnation. Qhov ntau ntawm cov kua nplaum yuav tsum yog nyob ntawm qhov chaw hauv lub pob tawb immersion. Tshem lub tshuab nqus tsev mus rau qhov qub siab.

⑷ Yog tias tsim nyog, qhib lub compressor, thiab siv cov cua compressed los nias cov kua nplaum rau hauv cov qhov micro-qhov lossis cov kab nrib pleb hauv qhov chaw. Lub compressed cua siab nyob ntawm qhov xwm txheej tshwj xeeb. Yog tias tsis muaj cov cai tshwj xeeb, cov cua compressed tuaj yeem yog 0 8-1 0MPa. Sijhawm 15 feeb. Tom qab infiltration, qhib lub qhov cua valve kom txo qhov siab.
