Tungsten carbide tsiri an fi yin shi da WC tungsten carbide da Co cobalt foda gauraye ta hanyar ƙarfe ta hanyar juzu'a, milling ball, latsawa da sintering, babban gami da aka gyara sune WC da Co, abun ciki na WC da Co a daban-daban amfani na tungsten carbide tsiri. ba iri ɗaya ba ne, kuma kewayon amfani yana da faɗi sosai.
Daya daga cikin mafi yawan kayan tungsten carbide tube, ana kiransa saboda siffar rectangular na faranti (ko murabba'ai), wanda kuma aka sani da tungsten carbide strip/plates. Tungsten carbide tsiri yana da kyau kwarai tauri, mai kyau lalacewa juriya, high na roba modulus, high compressive ƙarfi, mai kyau sinadaran kwanciyar hankali (acid, alkali, high zafin jiki hadawan abu da iskar shaka juriya), low tasiri tauri, low fadada coefficient, thermal da lantarki watsin kama da baƙin ƙarfe da kuma ta. gami.
Menene dalilai nalalatana tungsten carbide tube? Chuangrui carbide zai amsa a gaba:
(1) Ba a yi yashi ko gogewa a saman brazing na tungsten carbide kafin waldawa, kuma ɗigon oxide akan saman brazing yana rage tasirin jiƙa na ƙarfe na brazing kuma yana raunana ƙarfin haɗin gwiwa na walda.
(2)RushewaHakanan zai faru lokacin da ba a zaɓi wakili na brazing ba kuma an yi amfani da shi ba daidai ba, misali, lokacin da ake amfani da borax a matsayin wakili na brazing, borax ba zai iya taka rawar deoxidizing yadda ya kamata ba saboda borax yana da ɗanɗano mai yawa, kuma kayan aikin brazing ba zai iya jika sosai ba. a kan brazed surface, da kumalalataal'amari yana faruwa.
(3) Madaidaicin zafin jiki na brazing ya kamata ya zama 30 ~ 50 ° C sama da wurin narkewa na ƙarfe na brazing, kumalalatazai faru idan yanayin zafi ya yi yawa ko ƙasa. Dumama da yawa na iya haifar da oxidation a cikin walda. Yin amfani da ƙarfe mai ƙunshe da zinc zai ba wa weld ɗin launin shuɗi ko fari. Lokacin da zafin jiki na brazing ya yi ƙasa sosai, za a samar da weld mai kauri mai kauri, kuma za a rufe cikin walda da porosity da kuma haɗaɗɗen sag. Sharuɗɗa guda biyu da ke sama za su rage ƙarfin walda, kuma yana da sauƙi a gurɓata lokacin da aka kaifi ko amfani da shi.
(4) A cikin aikin brazing, babu wani lokacin da aka yi watsi da slag ko rashin isassun ƙwanƙwasa, don haka babban adadin slag ɗin ya kasance a cikin walda, wanda ke rage ƙarfin walda kuma yana haifar da lalacewa.lalata.
