Hanyoyin Kera Maɓallan Carbide
Hanyoyin Kera Maɓallan Carbide
Tungsten carbide yana daya daga cikin mafi yawan kayan da ake amfani da su a masana'antu a duniya. Ana yin maɓallin carbide daga tungsten carbide, don haka yana da kaddarorin simintin carbide. Siffar silinda na maɓalli na tungsten carbide yana ba da sauƙin sakawa cikin wasu kayan aikin ta hanyar shigar da zafi da latsa sanyi. Saboda maɓallan maɓalli na carbide suna riƙe da kaddarorin taurin, tauri, da dorewa, ya zama ruwan dare a gan su a yanayi daban-daban kamar hakar rijiyar, niƙa dutse, aikin hanya, da taron hakar ma'adinai. Amma ta yaya ake yin maɓallin carbide? A cikin wannan labarin, za mu gano wannan tambaya.
1. Raw Material Shiri
Hanyoyi masu zuwa suna buƙatar kayan WC foda da foda Cobalt. WC foda an yi shi da ma'adinan tungsten, hakowa kuma an ci tarar yanayi. Tungsten ores za su fuskanci kewayon halayen sinadarai, na farko tare da oxygen don zama tungsten oxide sannan tare da carbon don zama foda WC.
2. Hada foda
Yanzu ga mataki na farko yadda masana'antu ke yin haƙoran carbide. Masana'antu za su ƙara wasu masu ɗaure (Cobalt foda ko nickel foda) a cikin WC foda. Masu ɗaure kamar “manne” a rayuwarmu ta yau da kullun don taimakawa haɗakar tungsten carbide sosai. Dole ne ma'aikata su gwada cakuda foda don tabbatar da cewa zai iya amfani da shi a cikin matakai masu zuwa.
3. Rigar Milling
A yayin wannan aikin, za a saka foda mai gauraya a cikin Injin Milling Machine kuma a niƙa da ruwa kamar ruwa da ethanol. Wannan ruwa ba zai amsa sinadarai ba amma yana sauƙaƙe niƙa.
4. Fesa bushewa
Wannan hanya koyaushe tana faruwa a cikin na'urar bushewa. Amma masana'antu daban-daban na iya zaɓar nau'ikan inji daban-daban. Nau'ukan inji iri biyu ne na gama gari. Daya shine Injin bushewa; ɗayan kuma shine Hasumiyar bushewa. Suna da amfaninsu. Fesa aikin bushewa tare da zafi mai zafi da iskar gas don kawar da ruwa. Yana iya ƙafe mafi yawan ruwa, wanda ya fi dacewa ga hanyoyin biyu masu zuwa Dannawa da Sintering. Drying Vacuum baya buƙatar wannan zafin zafin amma yana da tsada kuma yana da tsada sosai don kulawa.
5. Dannawa
Don danna foda a cikin siffofi daban-daban waɗanda abokan ciniki ke buƙata, ma'aikata za su fara yin ƙira. Maɓallan Carbide sun zo da siffofi daban-daban don haka za ku iya ganin nau'ikan matattu daban-daban, tare da kai mai kaifi, kan ball, kan parabolic, ko kan cokali, tare da chamfer ɗaya ko biyu, kuma tare da ko ba tare da fitilun ba. Akwai hanyoyi guda biyu na tsarawa. Don ƙananan maɓalli, ma'aikata za su danna ta na'ura ta atomatik; don mafi girma, ma'aikata za su danna ta na'ura mai latsawa ta hydraulic.
6. Zumunci
Ma'aikata za su sanya tukwici bit carbide da aka danna akan farantin graphite kuma a cikin Hot Isostatic Pressing (HIP) Sintered Furnace a ƙarƙashin zafin jiki na kusan 1400˚ C. Dole ne a ɗaga zafin jiki a ƙananan gudu don maɓallin carbide yana raguwa a hankali kuma ya ƙare. button yana da mafi kyawun aiki. Bayan an haɗa shi, zai ragu kuma yana da kusan rabin girma kamar da.
7. Tabbatar da inganci
Binciken inganci yana da mahimmanci. Ana fara bincika abubuwan da ake sakawa na Carbide don kaddarorin kamar taurin, cobalt Magnetic, da microstructure don bincika ramuka ko ƙananan fasa. Ya kamata a yi amfani da micrometer don duba girmansa, tsayinsa, da diamita kafin shiryawa.
Don taƙaitawa, samar da ciminti tungsten carbide maballin saka ya kamata ya bi hanyoyin:
1. Raw Material Shiri
2. Hada foda
3. Rigar Milling
4. Fesa bushewa
5. Dannawa
6. Zumunci
7. Tabbatar da inganci
