Tasirin thermal akan Cutter PDC

An san cewa raƙuman ruwa na PDC sun fi naɗaɗɗen mazugi, amma ana ganin wannan a al'ada lokacin hako duwatsu masu laushi. Wannan na iya zama saboda gaskiyar cewa kashi 50% na makamashi don hakowa na iya bazuwa ta hanyar abin da aka sawa. Baya ga lalacewa da ke haifar da hulɗar da ke tsakanin dutsen da mai yankewa, tasirin zafi na iya haɓaka ƙimar abin da mai yanke zai sa.

Idan an yi watsi da tasirin thermal, zai iya haifar da raguwar raguwar kasancewa aiki ne kawai na nauyin da aka yi amfani da shi a ɗan ɗan lokaci da nisan tafiya yayin da ake hulɗa da dutsen. Kamar yadda muka sani, ba haka lamarin yake ba. Tasirin thermal yana da tasiri akan ƙimar da raguwa ke sawa.

An bayyana cewa lalatawar ƙarfe na ƙarfe yana da alaƙa da ƙimar taurin abu da ƙarfe. Don abrasives mai laushi tare da rabo ƙasa da 1.2, ƙimar lalacewa yana da ƙasa. Yayin da rabon taurin dangi ya wuce 1.2, yawan lalacewa yana ƙaruwa sosai.

Lokacin kallon ma'adini, wanda ke ko'ina daga 20-40% na yawancin nau'ikan dutse, taurin yana tsakanin 9.8-11.3GPa da na tungsten carbide shine 10-15GPa. Waɗannan jeri yana haifar da rabon da ya fito daga 0.65 zuwa 1.13, yana rarraba wannan alaƙar a matsayin mai laushi mai laushi. Lokacin da ake amfani da tungsten carbide don yankan duwatsu a ko ƙasa da 350 oC, suna fuskantar ƙarancin lalacewa wanda yayi kama da na lalata mai laushi kamar yadda ake tsammani.

Lokacin da zafin jiki ya wuce 350 oC, sawa yana haɓaka kuma yana da alaƙa mafi kyau da na ƙaƙƙarfan ƙura. Daga wannan, an yanke shawarar cewa lalacewa yana ƙaruwa da tasirin thermal. Don rage lalacewa na PDC, zai kasance da fa'ida don sarrafa zafin jiki na masu yankan.

Lokacin da aka fara nazarin tasirin zafi akan lalacewa na PDC, 750oC shine matsakaicin yanayin aiki mai aminci. An kafa wannan zafin jiki, saboda a ƙasa da wannan zafin jiki na microchipping shine lalacewa da aka gani akan mai yanke.

Sama da 750 ℃ ​​cikakkun hatsin lu'u-lu'u ana cire su daga saman lu'u-lu'u kuma lokacin da aka kai yanayin zafi sama da 950 ℃ ingarma ta tungsten carbide ta sami nakasar filastik. Fahimtar masu yankewa da PDC bit geometry dole ne su kasance daidai don samar da isassun bayanai yayin yin ɗan zaɓi.

Zzbetter yana ba da babban abin yanka PDC tare da kwanciyar hankali mai kyau. Ƙungiyarmu tana aiki tuƙuru sosai don kera samfuran inganci. Muna sa ran hidimar kasuwancin ku.

Idan kuna sha'awar masu yankan PDC kuma kuna son ƙarin bayani da cikakkun bayanai, kuna iya tuntuɓar mu ta waya ko wasiku a hagu, ko AIKA WASkon Amurka a kasan shafin.
