I-carbide enosimende iwumkhiqizo we-powder metallurgy owenziwe nge-carbide (WC, TiC) yezinga le-micron-level powder of high hardness refractory metal njengengxenye eyinhloko, ene-cobalt (Co) noma i-nickel (Ni), i-molybdenum (Mo) njenge-binder, enentshisekelo i-vacuum furnace noma isithando sokunciphisa i-hydrogen.
Ukuhlukaniswa kanye namaBanga
①I-Tungsten ne-Cobalt Cemented Carbide
Ingxenye eyinhloko i-tungsten carbide (WC) ne-binder cobalt (Co).
Ibanga lakhiwe ngokuthi “YG” (“hard, cobalt” ngesi-Hanyu Pinyin) kanye nephesenti lokuqukethwe kwe-cobalt okumaphakathi.
Isibonelo, i-YG8, isho i-WCo emaphakathi = 8%, kanti enye i-tungsten carbide carbide.
②I-tungsten, i-titanium ne-cobalt efakwe usimende carbide
Izingxenye eziyinhloko yi-tungsten carbide, i-titanium carbide (TiC) ne-cobalt.
Ibanga lakhiwe ngokuthi “YT” (“hard, titanium” ngesi-Hanyu Pinyin) kanye nesilinganiso sokuqukethwe kwe-titanium carbide.
Isibonelo, i-YT15, isho isilinganiso se-WTi = 15%, okusele i-tungsten carbide nokuqukethwe kwe-cobalt ye-tungsten titanium cobalt carbide.
③Tungsten-titanium-tantalum (niobium) uhlobo lwe-carbide
Izingxenye eziyinhloko yi-tungsten carbide, i-titanium carbide, i-tantalum carbide (noma i-niobium carbide) ne-cobalt.Lolu hlobo lwe-carbide lubizwa nangokuthi i-general-purpose carbide noma i-universal carbide.
Amazwe akhiqizayo amakhulu
Kunamazwe angaphezu kuka-50 emhlabeni akhiqiza i-carbide enosimende, futhi inani eliphelele lingafinyelela ku-27,000-28,000t-, amazwe akhiqizayo ayinhloko yi-USA, Russia, Sweden, China, Germany, Japan, UK, France, njll. Imakethe ye-carbide enosimende ngokuyisisekelo isesimweni sokugcwala, futhi ukuncintisana kwemakethe kushubile kakhulu.Imboni yaseShayina ye-carbide enosimende yasungulwa ngasekupheleni kwawo-1950, futhi yathuthuka ngokushesha kusukela ngawo-1960 kuya ko-1970.Ekuqaleni kwawo-1990, inani lokukhiqiza laseShayina le-carbide enosimende lafinyelela ku-6000t, kanti inani eliphelele le-carbide enosimende lafinyelela ku-5000t, likleliswe endaweni yesi-3 emhlabeni ngemva kweRussia ne-United States.
Izinduku ze-Carbide zingamathuluzi okusika i-carbide, afanele imingcele ehlukene yokugaya, izinto zokusika kanye nezinto ezingezona ezensimbi.Isetshenziswa kuma-lathes ajwayelekile kanye ne-semi-automatic, njll.
Okokuqala, ibha ye-carbide inohlu olubanzi lwezinhlelo zokusebenza emkhakheni wemishini.Ingasetshenziselwa ukwenza amathuluzi okuguqula isivinini esikhulu, amathuluzi okugaya, amakhanda e-cobalt, amathuluzi okubuyisela kabusha namanye amathuluzi okudweba, angathuthukisa isivinini sokusika.
Ingakwazi ukuthuthukisa isivinini sokusika nokusebenza kahle, ukunciphisa izindleko zokucubungula, futhi iphinde iqinisekise ukunemba kanye nekhwalithi ephezulu yezingxenye zomshini.
Okwesibili, emkhakheni wokucubungula impahla, izinduku ze-carbide ezinosimende nazo zinezinhlelo zokusebenza ezibalulekile.
Ingenza izinsimbi zokugaya uwoyela, izinsimbi zokubhoboza amatshe, izingcezu zokusika nokunye okufayo, okungagcina ukusebenza okuzinzile ngaphansi kwemvelo enzima yamandla aphezulu, ubulukhuni obuphezulu nokucindezela okuphezulu, ukuthuthukisa ngempumelelo ukusebenza kahle kokucubungula kanye nekhwalithi.
Ngaphezu kwalokho, izinduku ze-carbide ezinosimende nazo zidlala indima ebalulekile emkhakheni wezimayini.Ingasetshenziselwa ukwenza amathuluzi okumba izimayini, amathuluzi okumba amalahle, amathuluzi okumba i-geological kanye namanye amathuluzi, angakwazi ukwenza izinhlobo ezahlukene zokumba, ukubhoboza, ukutholwa kwamaphutha kanye neminye imisebenzi endaweni yezimayini eyinkimbinkimbi kanye ne-multi-intersection, ukuqinisekisa ukuphepha. kanye nokutholakala okunembile kwendawo yezimayini.
Ngokuvamile, izinduku ze-carbide ezinokumelana nokugqoka okuphezulu, amandla aphezulu nokusebenza okuphezulu kokushisa zisetshenziswa kabanzi ekukhiqizeni imishini, ukucubungula izinto ezibonakalayo, izimayini nezinye izinkambu, ezingathuthukisa ukuqina nokusebenza kahle kwamathuluzi, futhi ngaleyo ndlela kuzuzwe ukusebenza kahle kwezimboni, ukonga amandla kanye nemvelo. ukuthuthukiswa kokuvikela.
Izici:
Isetshenziswa kakhulu ku-PCB drill bits, izinhlobo ezahlukene zezigayo zokugcina, ama-reamer, ama-reaming drill, njll.;
- Ukusetshenziswa kwe-ultra-fine specication sub-micron, inhlanganisela ephelele yokumelana nokugqokwa okuhle kakhulu kanye nokuqina komthelela;
- Ukumelana nokuguquguquka nokuchezuka;
- I-China tungsten Online inobuchwepheshe obuphambili bokukhiqiza be-tungsten alloy round bar;
Indlela "yokuguqula" ibha eyindilinga ye-carbide ibe ithuluzi le-carbide?Ngokuthuthuka okuqhubekayo kwezinga lezimboni, izidingo zekhwalithi ze-carbide round bar nazo ziyanda.Embonini yemishini enembayo ephezulu, ukuphela kwamathuluzi e-carbide kunomthelela obulalayo ekunembeni kwemikhiqizo, futhi izinga lenkomba yokuphuma kwamathuluzi linqunyelwe ikakhulukazi inkomba yesilinda yamabha e-carbide.Enqubweni yokukhiqiza ye-carbide bar, i-cylindrical yebha enentshisekelo engenalutho ithintwa yinqubo yezinto ezibonakalayo kanye ne-powder metallurgy, ngakho-ke ukulawulwa kwe-cylindrical ye-carbide fine grinding bar ikakhulukazi ekucubunguleni okulandelayo kanye nokwelashwa okukhethekile.Ngokuvamile, indlela eyinhloko yokucubungula imigoqo ye-carbide iwukugaya okuphakathi nendawo.Inqubo yokugaya ephakathi nendawo yakhiwe izingxenye ezintathu: isondo lokugaya, isondo lokulungisa kanye nesibambi somsebenzi, lapho isondo lokugaya empeleni lisebenza njengomsebenzi wokugaya, isondo lokulungisa lilawula ukujikeleza komsebenzi futhi libangele ucezu lomsebenzi ukuba lwenzeke. ngesilinganiso sokuphakelayo, futhi ngokuqondene nomnikazi wesiqeshana somsebenzi, osekela ucezu lomsebenzi ngesikhathi sokugaya, lezi zingxenye ezintathu zingaba nezindlela eziningana zokubambisana (ngaphandle kokuyeka ukugaya), zonke ezifanayo ngokwesimiso.
I-Cylindrical inkomba ebanzi yokulinganisa ukujikeleza nokuqondile kwebha.I-cylindrical yebha ye-carbide ithintwa kakhulu ukuphakama okumaphakathi kwesiqephu somsebenzi esicutshunguliwe, inani lokuphakelayo kwamathuluzi, isivinini sokuphakelayo, kanye nesivinini sokuzungezisa sesondo lomhlahlandlela enqubweni yokugaya engenamaphakathi.Ngakho bamba inkomba ye-cylindrical ukuze wenze ibha ye-carbide "iguqulwe" ngempumelelo ibe ithuluzi lekhwalithi ephezulu ye-carbide.
