Njira Zopangira Mabatani a Carbide

Tungsten carbide ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi. Bokosi la carbide limapangidwa kuchokera ku tungsten carbide, kotero ili ndi mphamvu ya simenti ya carbide. Mawonekedwe a silinda a mabatani a tungsten carbide amapangitsa kuti zikhale zosavuta kuyika mu zida zina poyika kutentha ndi kukakamiza kuzizira. Chifukwa zoyikapo mabatani a carbide zimakhala ndi kuuma, kulimba, komanso kulimba, ndizofala kuziwona m'malo osiyanasiyana monga kubowola bwino, kugaya miyala, kuyendetsa msewu, ndi zochitika zamigodi. Koma kodi batani la carbide limapangidwa bwanji? M’nkhani ino, tiyankha funso limeneli.

1. Kukonzekera Zopangira Zopangira

Njira zotsatirazi zimafuna zida za WC ufa ndi ufa wa Cobalt. WC ufa amapangidwa ndi tungsten ores, migodi ndi chindapusa kuchokera chilengedwe. Tungsten ores amakumana ndi machitidwe osiyanasiyana amankhwala, choyamba ndi mpweya kukhala tungsten oxide kenako ndi mpweya kukhala WC ufa.

2. Kusakaniza Ufa

Tsopano apa pali sitepe yoyamba momwe mafakitale amapangira mano a carbide. Mafakitole adzawonjezera zomangira (Cobalt ufa kapena Nickel ufa) mu WC ufa. Zomangira zili ngati "glue" m'moyo wathu watsiku ndi tsiku kuti athandizire kuphatikiza tungsten carbide mwamphamvu kwambiri. Ogwira ntchito ayenera kuyesa ufa wosakanizidwa kuti atsimikizire kuti ukhoza kugwiritsa ntchito njira zotsatirazi.

3. Kunyowa Kugaya

Panthawi imeneyi, ufa wosakaniza udzayikidwa mu Makina Opangira Mpira ndi kugayidwa ndi madzi monga madzi ndi Mowa. Izi madzi sadzachita mankhwala koma facilitates akupera.

4. Utsi Kuyanika

Izi zimachitika nthawi zonse mu chowumitsira. Koma mafakitale osiyanasiyana amatha kusankha makina osiyanasiyana. Mitundu iwiri yotsatirayi ya makina ndi yofala. Chimodzi ndi Chowumitsira Vuto; ina ndi Spray Drying Tower. Iwo ali ndi ubwino wawo. Utsi ntchito kuyanika ndi kutentha kwambiri ndi mpweya inert kuti asungunuke madzi. Imatha kusungunula madzi ambiri, zomwe zimapangitsa njira ziwiri zotsatirazi Kukanikiza ndi Sintering. Kuyanika mu Vacuum sikufuna kutentha kwambiri koteroko koma ndikokwera mtengo ndipo kumawononga ndalama zambiri kuti musamalidwe.

5. Kukanikiza

Kuti akanikizire ufa mumitundu yosiyanasiyana yomwe makasitomala amafunikira, ogwira ntchito amayamba kupanga nkhungu. Mabatani a Carbide amabwera m'mawonekedwe osiyanasiyana kotero kuti mutha kuwona mitundu yosiyanasiyana yakufa, yokhala ndi mutu wopindika, mutu wa mpira, mutu wofananira, kapena mutu wa spoon, wokhala ndi chamfers chimodzi kapena ziwiri, komanso wopanda ma pinholes. Pali njira ziwiri zopangira. Kwa mabatani ang'onoang'ono, ogwira ntchito azisindikiza ndi makina okhawo; kwa chokulirapo, ogwira ntchito amakanikizira ndi makina osindikizira a hydraulic.

6. Sintering

Ogwira ntchito adzayika nsonga za carbide bit pa mbale ya graphite ndi mu Hot Isostatic Pressing (HIP) Sintered Furnace pansi pa kutentha kwa pafupifupi 1400˚ C. Kutentha kuyenera kukwezedwa ndi liwiro lotsika kuti batani la carbide lichepetse pang'onopang'ono ndi kutsirizika. batani ili ndi ntchito yabwinoko. Pambuyo pa sintering, imachepa ndipo imangokhala ndi theka la voliyumu yochuluka monga kale.

7. Kufufuza kwabwino

Macheke abwino ndi ofunika kwambiri. Kuyika kwa carbide kumawunikiridwa koyamba ngati kuuma, maginito a cobalt, ndi ma microstructure kuti ayang'ane mabowo kapena ming'alu yaying'ono. Ma micrometer ayenera kugwiritsidwa ntchito kuti aone kukula kwake, kutalika kwake, ndi m'mimba mwake asananyamuke.
