Indlela yokuvelisa i-Carbide Substrate yePDC Cutters

Abasiki bePDC basetyenziswa kakhulu kwimigodi, ioyile, kunye namashishini okugrumba irhasi. Njengoko sisazi, isakhiwo se-PDC cutter sineenxalenye ezimbini, enye i-diamond layer, kwaye enye i-carbide substrate. Abasiki bePDC badibanisa kunye nedayimane ngobulukhuni obuphezulu kunye ne-carbide substrate ekuchaseni impembelelo. Umsiki wePDC okumgangatho ophezulu awufuni itekhnoloji elungileyo kuphela, kodwa kunye nemathiriyeli ekrwada yeprimiyamu. I-substrate ye-carbide idlala indima ebalulekileyo kuyo. Namhlanje singathanda ukwabelana ngendlela eyaveliswa ngayo i-carbide substrate.

I-Cemented carbide (i-tungsten carbide) yinto enzima eyenziwe ngamaqhekeza amancinci e-carbide afakwe kwi-composite yi-binder metal. I-Cemented Carbides zifumana ubulukhuni bazo kwiinkozo ze-Tungsten Carbide kunye nokuqina kwazo kwi-bonding eveliswa yisenzo se-cementing ye-Cobalt metal. Ngokutshintsha inani le-Cobalt, sinokutshintsha ukuqina, ukumelana nokunxiba, kunye nokuqina (umothuko okanye ukuchasana kwempembelelo) ye-carbide ukubonelela ngokusebenza okuphezulu kwisicelo sakho esithile. Ibakala le-carbide le-PDC cutter substrate liyahluka ukusuka kwi-YG11 ukuya kwi-YG15.

Eyona nkqubo yokuvelisa i-carbide substrate yile ingezantsi:

Ifomula malunga nebakala: Okokuqala, i-WC powder, i-cobalt powder, kunye nezinto ze-doping ziya kuxutywa ngokwefomula esemgangathweni yiZithako ezinamava. Ngokomzekelo, kwibakala lethu le-UBT20, liya kuba yi-10.2% ye-Cobalt, kwaye ibhalansi yi-WC powder kunye ne-doping elements.

Umgubo wokusila omanzi: Umgubo oxutyiweyo weWC, umgubo wecobalt kunye nezinto zedoping ziya kufakwa kumatshini wokusila omanzi. Ukugaya ibhola emanzi kuya kuhlala iiyure eziyi-16-72 malunga nobuchwepheshe bemveliso eyahlukeneyo.

Ukomisa umgubo: Emva kokugaya, umgubo uya kutshizwa womiswe ukuze ufumane umgubo owomileyo okanye igranulate. Ukuba indlela yokwenza i-extrusion, i-powder edibeneyo iya kuxutywa kwakhona nge-Adhesive.

Ukucinezela ngundo: Lo mxube we powder ufakwe kwi-mold kwaye ucinezele ngoxinzelelo oluphezulu kwimilo.

Sintering: Kwi-1380℃, i-cobalt iya kuhamba kwiindawo ezikhululekile phakathi kweenkozo ze-tungsten carbide. Ixesha le-sintering limalunga neeyure ezingama-24 ngokuxhomekeke kumabakala ahlukeneyo kunye nobukhulu.

I-ZZbetter inolawulo olungqongqo lwemathiriyeli ekrwada yegrit yedayimane kunye ne-carbide substrate. Yiyo loo nto sinokukuvelisela abasiki bePDC abakumgangatho ophezulu.

I-ZZbetter inoluhlu olupheleleyo lobungakanani bee-PDC cutters zokhetho lwakho. Ukuhanjiswa ngokukhawuleza kwiintsuku ze-5 ukugcina ixesha lakho. Umyalelo wesampula wamkelekile kuvavanyo. Xa ufuna ukuhlaziya isuntswana lakho le-drill, i-ZZbetter inokukunika i-PDC cutter ngokukhawuleza.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
