Izici nokusetshenziswa kwe-Cemented Carbide

Izici ze-tungsten carbide

I-Tungsten carbide inokuqina okuphezulu nokumelana nokugqoka. Ijubane lokusika lamathuluzi e-carbide liphakeme izikhathi ezi-4 kuya kweziyi-7 kunelensimbi enesivinini esikhulu kanye nezikhathi ezi-5 kuye kwezingama-80 impilo yesevisi ephakeme. Imikhiqizo ye-Carbide ingasika izinto eziqinile ezingaba ngu-50HRC. Lezi zihloko zizokwethula ulwazi olubalulekile mayelana ne-carbide enosimende.

Izinto ezibonakalayo ze-tungsten carbide

I-carbide enosimende ngokuyinhloko iyimpushana ewusayizi omncane we-carbides (WC, TiC) yezinsimbi eziphikisayo ezinokuqina okuphezulu. Izingxenye eziyinhloko imikhiqizo eyimpuphu yensimbi efakwe esithandweni somlilo noma isithando somlilo sokunciphisa i-hydrogen ene-cobalt (Co), i-nickel (Ni), ne-molybdenum (Mo) njengesibophezelo.

I-matrix ye-carbide enosimende yakhiwe izingxenye ezimbili: ingxenye eyodwa yisigaba sokuqina, kanti enye ingxenye iyinsimbi yokubopha.

Isigaba esiqinile yi-carbide, njenge-tungsten carbide, i-titanium carbide, ne-tantalum carbide. Ukuqina kwayo kuphakeme kakhulu. Izindawo zayo zokuncibilika zingaphezu kuka-2000°C, kanti ezinye zize zedlule ku-4000°C. Ukuba khona kwesigaba sokuqina kunquma ubulukhuni obuphezulu kakhulu nokumelana nokugqoka kwe-carbide.

Izidingo zikasayizi wokusanhlamvu we-Tungsten carbide WC ze-carbide enosimende zisebenzisa usayizi wokusanhlamvu ohlukile we-WC ngokuya ngezicelo ezahlukahlukene.

Lesi sihloko sethula ikakhulukazi ukusetshenziswa okuthathu kwe-carbide enosimende:

1. I-Tungsten carbide yokwenza amathuluzi okusika i-carbide

Amathuluzi okusika i-Carbide asetshenziswa kabanzi ukusika insimbi nokwenza imishini. Ama-alloys omshini amahle njengama-foot cutter blades nemimese ye-V-CUT asebenzisa i-ultra-fine, sub-fine, kanye ne-WC elungiswe kahle. Ama-alloys ama-rough-machining asebenzisa i-WC yezinhlamvu ezimaphakathi. Ama-alloys okusika amandla adonsela phansi kanye nezinsimbi zokusika ezisindayo zisebenzisa i-Granular WC ephakathi nendawo futhi emahhadla njengempahla eluhlaza.

2. I-carbide enosimende yokwenza amathuluzi okumba i-carbide

Idwala linobulukhuni obuphezulu kanye nomthwalo onomthelela omkhulu. I-coarse WC yamukelwa, futhi umthelela wedwala mncane ngomthwalo omncane. I-WC enosayizi omaphakathi isetshenziswa njengempahla eluhlaza.

3. I-Hard alloy yokwenza izingxenye ze-carbide ezingagugi

Uma kugcizelela ukumelana kwayo nokugqokwa, ukumelana nokucindezela, kanye nokuqedwa kwendawo, i-WC enobukhulu obuhlukene isetshenziswa njengempahla eluhlaza, kanti impahla eluhlaza ye-WC ephakathi nendawo kanye ne-coarse-grained isetshenziswa njengento eyinhloko.

4. Insimbi eqinile yokwenza i-tungsten carbide Iyafa

I-carbide dies inempilo yesevisi ende ephindwe amashumi amaningana kunesikhunta sensimbi. Isikhunta se-carbide sinokuqina okuphezulu, amandla aphezulu, ukumelana nokugqwala, ukumelana nezinga lokushisa eliphezulu, kanye ne-coefficient encane yokwandisa, ngokuvamile eyakhiwe nge-tungsten cobalt.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
