Insimbi ye-tungsten (i-tungsten carbide) inezimpawu ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokuguguleka, ukuqina okuhle nokuqina, ukumelana nokushisa nokumelana nokugqwala, ikakhulukazi ukuqina kwayo okuphezulu nokumelana nokuguguleka, ngisho noma izinga lokushisa lingu-500 ℃. Ayishintshile ngokuphelele, futhi isenokuqina okuphezulu ku-1000 °C.

Igama lesiShayina: insimbi ye-tungsten

Igama langaphandle: Igama elingelona elenziwe nge-Carbide

Izici: Ubulukhuni obuphezulu, ukumelana nokuguguleka, amandla amahle nokuqina

Imikhiqizo: Induku eyindilinga, ipuleti lensimbi ye-tungsten

Isingeniso:

Insimbi ye-tungsten, eyaziwa nangokuthi i-carbide eqinisiwe, ibhekisela ezintweni ezihlanganisiwe ezihlanganisiwe eziqukethe okungenani i-carbide eyodwa yensimbi. I-Tungsten carbide, i-cobalt carbide, i-niobium carbide, i-titanium carbide, kanye ne-tantalum carbide yizingxenye ezivamile zensimbi ye-tungsten. Usayizi wezinhlamvu zengxenye ye-carbide (noma isigaba) ngokuvamile uphakathi kwama-microns angu-0.2-10, kanti izinhlamvu ze-carbide zihlanganiswa ndawonye kusetshenziswa i-metallic binder. I-binder ivame ukubhekisela ku-cobalt yensimbi (Co), kodwa kwezinye izinhlelo zokusebenza ezikhethekile, i-nickel (Ni), insimbi (Fe), noma ezinye izinsimbi nama-alloy nazo zingasetshenziswa. Inhlanganisela yokwakheka kwe-carbide kanye nesigaba se-binder okufanele inqunywe ibizwa ngokuthi “ibanga”.

Ukuhlukaniswa kwensimbi ye-tungsten kwenziwa ngokwezindinganiso ze-ISO. Lokhu kuhlukaniswa kusekelwe ohlotsheni lwezinto zokwakha (njenge-P, M, K, N, S, H grades). Ukwakheka kwesigaba se-binder kusetshenziselwa kakhulu amandla ayo kanye nokumelana nokugqwala.

I-matrix yensimbi ye-tungsten inezingxenye ezimbili: ingxenye eyodwa iyisigaba sokuqina; enye ingxenye iyinsimbi yokubopha. Izinsimbi ze-binder ngokuvamile ziyizinsimbi zeqembu lensimbi, ezivame ukusetshenziswa njenge-cobalt ne-nickel. Ngakho-ke, kunezinhlobo ze-tungsten-cobalt, izinhlobo ze-tungsten-nickel kanye nezinhlobo ze-tungsten-titanium-cobalt.

Ngezinsimbi eziqukethe i-tungsten, njengensimbi esheshayo kanye nezinye izinsimbi ezishisayo, okuqukethwe kwe-tungsten ensimbini kungathuthukisa kakhulu ubulukhuni kanye nokumelana nokushisa kwensimbi, kodwa ukuqina kuzokwehla kakhulu.

Ukusetshenziswa okuyinhloko kwezinsiza ze-tungsten nakho kuyi-carbide eqinisiwe, okungukuthi, insimbi ye-tungsten. I-Carbide, eyaziwa ngokuthi amazinyo ezimboni zanamuhla, isetshenziswa kabanzi emikhiqizweni yensimbi ye-tungsten.

Isakhiwo sesithako

Inqubo yokuhlanza:

Ukushiswa kwensimbi ye-tungsten kuwukucindezela i-powder ibe yi-billet, bese ungena esithandweni sokushiswa ukuze ushiswe kufike ezingeni lokushisa elithile (izinga lokushisa lokushiswa), uyigcine isikhathi esithile (isikhathi sokubamba), bese uyipholisa, ukuze uthole izinto zensimbi ye-tungsten ezinezakhiwo ezidingekayo.

Izigaba ezine eziyisisekelo zenqubo yokusila insimbi ye-tungsten:

1. Esigabeni sokususa i-ejenti yokwakha kanye nokuhlikihla ngaphambi kokuhlikihla, umzimba ohlikihliwe ubhekana nezinguquko ezilandelayo kulesi sigaba:

Ukususwa kwe-ejenti yokubumba, ngokuphakama kwezinga lokushisa esigabeni sokuqala sokubumba, i-ejenti yokubumba iyabola kancane kancane noma iphele, bese umzimba omboziwe ukhishwa. Uhlobo, ubuningi kanye nenqubo yokubumba kuhlukile.

Ama-oxide ebusweni bempuphu ayancishiswa. Lapho izinga lokushisa lincishiswa, i-hydrogen inganciphisa ama-oxide e-cobalt ne-tungsten. Uma into edala isuswa ku-vacuum bese incishiswa, ukusabela kwe-carbon-oxygen akunamandla. Ukucindezeleka kokuxhumana phakathi kwezinhlayiya zempuphu kuyasuswa kancane kancane, i-bonding metal powder iqala ukululama futhi iphinde isetshenziswe, ukusabalala kobuso kuqala ukwenzeka, futhi amandla e-briquetting ayathuthuka.

2. Isigaba sokusila esiqinile (800℃——izinga lokushisa le-eutectic)

Emazingeni okushisa ngaphambi kokuvela kwesigaba soketshezi, ngaphezu kokuqhubeka nenqubo yesigaba sangaphambilini, ukusabela kwesigaba esiqinile kanye nokusabalala kuyaqiniswa, ukugeleza kwepulasitiki kuyakhuliswa, futhi umzimba osikiwe uncipha kakhulu.

3. Isigaba sokusila sesigaba soketshezi (izinga lokushisa le-eutectic - izinga lokushisa lokusila)

Uma isigaba soketshezi sivela emzimbeni osikiwe, ukuncishiswa kuqedwa ngokushesha, kulandelwe ukuguqulwa kwekristalografikhi ukuze kwakheke isakhiwo esiyisisekelo kanye nesakhiwo se-alloy.

4. Isigaba sokupholisa (izinga lokushisa lokushisisa - izinga lokushisa legumbi)

Kulesi sigaba, isakhiwo kanye nokwakheka kwesigaba sensimbi ye-tungsten kunezinguquko ezithile ezihambisana nezimo zokupholisa ezahlukene. Lesi sici singasetshenziswa ukufudumala nokukhipha insimbi ye-tungsten ukuze kuthuthukiswe izakhiwo zayo zomzimba nezemishini.

Isingeniso sohlelo lokusebenza

Insimbi ye-tungsten ingeye-carbide eqinisiwe, eyaziwa nangokuthi i-tungsten-titanium alloy. Ubulukhuni bungafinyelela ku-89~95HRA. Ngenxa yalokhu, imikhiqizo yensimbi ye-tungsten (amawashi ensimbi ye-tungsten avamile) akulula ukuwagqoka, aqinile futhi awasabi ukuncibilika, kodwa ayaphuka.

Izingxenye eziyinhloko ze-carbide esimende yi-tungsten carbide kanye ne-cobalt, okubalwa u-99% wazo zonke izingxenye, kanti u-1% ezinye izinsimbi, ngakho-ke ibizwa nangokuthi insimbi ye-tungsten.

Ivame ukusetshenziswa ekusetshenzisweni komshini wokulungisa izinto ngokunemba okuphezulu, ezintweni zamathuluzi ngokunemba okuphezulu, emishinini yokugaya izinto, kuma-drill bits, kuma-glass cutter bits, kuma-tile cutters, aqinile futhi awesabi uku-annealing, kodwa ayaphuka kalula. Ingeyensimbi engavamile.

Insimbi ye-tungsten (i-tungsten carbide) inezici eziningi ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokuguguleka, amandla nokuqina okuhle, ukumelana nokushisa nokumelana nokugqwala, ikakhulukazi ubunzima bayo obukhulu nokumelana nokuguguleka, ngisho noma izinga lokushisa lingu-500 ℃. Ihlala ingashintshile, futhi isenokuqina okuphezulu ku-1000 °C. I-Carbide isetshenziswa kabanzi njengezinto zokwakha, njengamathuluzi okujika, okusika izigayo, ama-planer, ama-drill, amathuluzi okubhoboza, njll., ukusika insimbi ephothiwe, izinsimbi ezingezona i-ferrous, amapulasitiki, imicu yamakhemikhali, i-graphite, ingilazi, itshe kanye nensimbi evamile, futhi ingasetshenziswa futhi ekusikeni insimbi engamelani nomshini. Izinto ezinzima ukuzisebenzisela umshini njengensimbi eshisayo, insimbi engagqwali, insimbi ephezulu ye-manganese, insimbi yamathuluzi, njll. Ijubane lokusika le-carbide entsha efakwe ukhonkolo liphindwe kangamakhulu kunensimbi yekhabhoni.

Insimbi ye-tungsten (i-tungsten carbide) ingasetshenziswa futhi ukwenza amathuluzi okubhoboza amatshe, amathuluzi okumba, amathuluzi okubhoboza, amathuluzi okulinganisa, izingxenye ezingagugi, izinto zokukhuhla zensimbi, ama-lining esilinda, ama-bearings anembile, ama-nozzle, njll.

Ukuqhathaniswa kwamazinga ensimbi ye-tungsten: S1, S2, S3, S4, S5, S25, M1, M2, H3, H2, H1, G1 G2 G5 G6 G7 D30 D40 K05 K10 K20 YG3X YG3 YG4C YG6 YG8 YG10 YG12 YL10.2 YL60 YG15 YG20 YG25 YG28YT5 YT14 YT15 P10 P20 M10 M20 M30 M40 V10 V20 V30 V40 Z01 Z10 Z20 Z30

Insimbi ye-tungsten, imimese ye-carbide eqinisiwe, kanye nezinhlobo ezahlukene ze-tungsten carbide ezijwayelekile zinempahla enkulu, futhi izikhala ziyatholakala esitokweni.
