Menene tsarin samarwa don tungsten carbide?

1. Mataki na farko don yin samfurin tungsten carbide, shine yin foda. Foda shine haɗewar WC da Cobalt, an haɗa su tare a cikin wani takamaiman rabo. Alal misali, idan abokan ciniki suna buƙatar tungsten carbide heading mutu, so carbide grade YG20, adadin 100 kilos. Sannan mai yin powder zai hada garin cobalt mai nauyin kilogiram 18 da garin WC mai nauyin kilo 80, ma'aunin kilo 2 ne sauran foda na karfe da za'a saka a ciki kamar yadda kamfanin ya tsara na YG20. Za a saka duk foda a cikin injinan niƙa. Akwai iyakoki daban-daban na injunan niƙa, kamar 5kgs don samfura, 25kgs, 50kgs, 100kgs, ko mafi girma.

2. Bayan cakuda foda, mataki na gaba shine fesa da bushewa. A cikin Kamfanin Zhuzhou Better Tungsten Carbide, ana amfani da hasumiya mai feshi, wanda zai inganta aikin jiki da sinadarai na tungsten carbide foda. Foda da aka yi da hasumiya ta Fesa yana da kyakkyawan aiki fiye da sauran injina. Bayan kammala wannan tsari, foda yana cikin“shirye-don-latsawa” yanayi.

3. Za a danna foda bayan an gama“shirye-don-latsawa” foda an gwada lafiya. Akwai hanyoyi daban-daban na latsawa, ko kuma mu ce hanyoyi daban-daban na samfurori na tungsten carbide. Misali, idan masana'anta ta samar da tukwici na tungsten carbide saw, za a yi amfani da injin buga atomatik; idan ana buƙatar babban mutuƙar tungsten carbide, za a yi amfani da injin latsa rabin-hannu. Hakanan akwai wasu hanyoyin samar da samfuran carbide na tungsten, kamar sanyi isostatic latsa (gajeren suna CIP), da injunan extrusion.

4. Sintering shine tsari bayan latsawa, kuma shine tsari na ƙarshe don samar da ƙarfe na tungsten carbide wanda za'a iya amfani dashi azaman ƙarfin ƙarfi da ƙarfin ƙarfin injiniya don yanke, juriya, hakowa, ko wasu aikace-aikace. Yanayin zafin jiki na sintering yana da girma zuwa 1400 centigrade. Don ƙungiyoyi daban-daban, zafin jiki zai sami wasu bambance-bambance. A irin wannan babban zafin jiki, mai ɗaure zai iya haɗa foda WC kuma ya samar da tsari mai ƙarfi. Ana iya yin aikin sintering tare da ko ba tare da babban na'urar iskar gas mai isostatic (HIP).

Tsarin da ke sama shine bayanin sauƙi na tsarin samar da carbide da aka yi da siminti. Ko da yake ya yi kama da sauƙi, samar da tungsten carbide masana'antar tattara kayan fasaha ce ta fasaha. Ba abu mai sauƙi ba ne don samar da ƙwararrun samfuran carbide tungsten. Tungsten wani nau'i ne na albarkatun da ba za a iya sabuntawa ba, da zarar an yi amfani da shi, ba zai yiwu a sake samuwa a cikin ɗan gajeren lokaci ba. Yi la'akari da albarkatu masu mahimmanci, tabbatar da cewa kowane samfurin tungsten carbide ya ƙware kafin isa hannun abokan ciniki, yana ɗaya daga cikin mahimman dalilan da ke tura mu don yin mafi kyau. Ci gaba da motsi, ci gaba da ingantawa!
