Intshayelelo:

Intsimbi yeTungsten, ekwabizwa ngokuba yi-cemented carbide, ibhekisa kwinto ehlanganisiweyo edityanisiweyo equlethe ubuncinci i-carbide enye yentsimbi. I-tungsten carbide, i-cobalt carbide, i-niobium carbide, i-titanium carbide, kunye ne-tantalum carbide zizinto eziqhelekileyo zentsimbi ye-tungsten. Ubungakanani beenkozo zecandelo le-carbide (okanye isigaba) ngokuqhelekileyo phakathi kwe-0.2-10 microns, kwaye iinkozo ze-carbide zibanjwe kunye zisebenzisa i-binder yensimbi. Isibophelelo sikholisa ukubhekisa kwicobalt yesinyithi (Co), kodwa kwizicelo ezithile ezikhethekileyo, nickel (Ni), intsimbi (Fe), okanye ezinye iintsimbi kunye nealloys nazo zingasetyenziswa. Inhlanganisela edibeneyo ye-carbide kunye nesigaba se-binder esiza kugqitywa sibizwa ngokuba yi "grade".

Ukwahlula kwensimbi ye-tungsten kwenziwa ngokwemigangatho ye-ISO. Olu lwahlulo lusekwe kuhlobo lwezinto eziphathekayo (ezifana namabakala P, M, K, N, S, H). Ukubunjwa kwesigaba se-binder kusetyenziselwa amandla ayo kunye nokumelana nokubola.

I-matrix yensimbi ye-tungsten iqukethe iinxalenye ezimbini: enye inxalenye yinqanaba elinzima; enye inxalenye yintsimbi edibanisayo. Iintsimbi ezibophezelayo ziqhelekile ziintsimbi zeqela lentsimbi, icobalt esetyenziswa ngokuqhelekileyo kunye nenickel. Ngoko ke, kukho i-tungsten-cobalt alloys, i-tungsten-nickel alloys kunye ne-tungsten-titanium-cobalt alloys.

Kwiintsimbi eziqulethe i-tungsten, njengentsimbi yesantya esiphezulu kunye nezinye iintsimbi ezitshisayo zokusebenza, umxholo we-tungsten kwintsimbi unokuphucula kakhulu ukuqina kunye nokumelana nokushisa kwentsimbi, kodwa ukuqina kuya kuhla ngokukhawuleza.

Ukusetyenziswa okuphambili kwezixhobo ze-tungsten kwakhona i-carbide ene-cemented, oko kukuthi, i-tungsten steel. I-Carbide, eyaziwa ngokuba ngamazinyo oshishino lwanamhlanje, isetyenziswa ngokubanzi kwiimveliso zensimbi ye-tungsten.

Ubume bezithako

Inkqubo yeSintering:

I-Sintering yensimbi ye-tungsten kukucinezela umgubo kwi-billet, emva koko ungenise iziko lokutshisa ukutshisa kwiqondo elithile lobushushu (ubushushu be-sintering), uyigcine ixesha elithile (ubambe ixesha), kwaye uyipholise phantsi, ukuze ufumane. impahla yensimbi ye-tungsten eneempawu ezifunekayo.

Amanqanaba amane asisiseko enkqubo yensimbi ye-tungsten yokuthambisa:

1. Kwinqanaba lokususa i-arhente yokwenza kunye ne-pre-sintering, umzimba we-sintered wenza utshintsho olulandelayo kweli nqanaba:

Ukususwa kwe-ejenti yokubumba, kunye nokunyuka kweqondo lokushisa kwinqanaba lokuqala le-sintering, i-ejenti yokubumba ngokuthe ngcembe ibola okanye i-vaporize, kwaye umzimba we-sintered awubandakanywa. Uhlobo, ubuninzi kunye nenkqubo ye-sintering yahlukile.

Iioksidi kumphezulu womgubo ziyancipha. Kwiqondo lobushushu le-sintering, i-hydrogen inokunciphisa i-oxides ye-cobalt kunye ne-tungsten. Ukuba i-arhente yokwenza isuswe kwi-vacuum kwaye i-sintered, i-carbon-oxygen reaction ayinamandla. Ukuxinzezeleka koqhagamshelwano phakathi kweengqungquthela zepowder kupheliswa ngokuthe ngcembe, i-powder yensimbi edibeneyo iqala ukubuyisela kwaye iphinde ihlaziye, i-surface diffusion iqala ukwenzeka, kwaye amandla e-briquetting aphuculwe.

2. Inqanaba eliqinileyo lenqanaba le-sintering (800℃——ubushushu be-eutectic)

Kwiqondo lokushisa ngaphambi kokubonakala kwesigaba se-liquid, ngaphezu kokuqhubeka nenkqubo yesigaba sangaphambili, ukuphendulwa kwesigaba esiqinileyo kunye nokusabalalisa kuqiniswa, ukuhamba kweplastiki kuphuculwe, kwaye umzimba we-sintered uyancipha kakhulu.

3. Ulwelo isigaba sintering isigaba (ubushushu eutectic - sintering lobushushu)

Xa isigaba se-liquid sibonakala kumzimba we-sintered, i-shrinkage igqitywe ngokukhawuleza, ilandelwa ukuguqulwa kwe-crystallographic ukwenza isakhiwo esisisiseko kunye nesakhiwo se-alloy.

4. Inqanaba lokupholisa (ubushushu be-sintering - ubushushu begumbi)

Ngeli nqanaba, ukwakheka kunye nesigaba sokubunjwa kwensimbi ye-tungsten kunotshintsho oluthile kunye neemeko zokupholisa ezahlukeneyo. Eli nqaku lingasetyenziselwa ukutshisa intsimbi ye-tungsten ukuze kuphuculwe iimpawu zayo zomzimba kunye nezomatshini.

Intshayelelo yesicelo

Intsimbi yeTungsten yeyekhabide enesamente, ekwabizwa ngokuba yi-tungsten-titanium alloy. Ubunzima bunokufikelela kwi-89 ~ 95HRA. Ngenxa yoko, iimveliso zensimbi ze-tungsten (iiwotshi zensimbi eziqhelekileyo ze-tungsten) azilula ukugqithwa, zilukhuni kwaye zingoyiki ukuxhamla, kodwa zincinci.

Amacandelo aphambili e-carbide ene-cemented yi-tungsten carbide kunye ne-cobalt, eyenza i-99% yazo zonke izinto, kunye ne-1% yezinye isinyithi, ngoko ke kuthiwa yi-tungsten steel.

Ngokuqhelekileyo isetyenziswe kwi-high-precision machining, izixhobo zesixhobo ezichanekileyo, iileyile, i-drill drill bits, i-glass cutter bits, i-tile cutters, ilukhuni kwaye ingoyiki i-annealing, kodwa i-brittle. Yeyentsimbi enqabileyo.

Intsimbi yeTungsten (i-tungsten carbide) inoluhlu lweempawu ezigqwesileyo ezinjengokuqina okuphezulu, ukuxhathisa ukunxiba, ukomelela okuhle kunye nokuqina, ukumelana nobushushu kunye nokumelana nomhlwa, ngakumbi ukuqina kwayo okuphezulu kunye nokumelana nokunxiba, nokuba kubushushu obungama-500 ℃. Ihlala ingatshintshanga, kwaye isenobunzima obuphezulu kwi-1000 °C. I-Carbide isetyenziswa ngokubanzi njengezinto eziphathekayo, ezifana nezixhobo zokuguqula, ii-milling cutters, iiplani, ii-drills, izixhobo ezikruqulayo, njl. kwaye ingasetyenziselwa ukusika intsimbi enganyangekiyo. Izinto ezinzima kumatshini ezifana nentsimbi eshushu, insimbi engenasici, insimbi ephezulu ye-manganese, insimbi yesixhobo, njl.

I-Tungsten steel (i-tungsten carbide) ingasetyenziselwa ukwenza izixhobo zokwemba amatye, izixhobo zemigodi, izixhobo zokubhoboza, izixhobo zokulinganisa, iindawo ezingagugiyo, i-abrasives yesinyithi, i-cylinder linings, iibheringi ezichanekileyo, imilomo, njl.

Ukuthelekiswa kwamabanga entsimbi 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 YL00 YL10 YG20 YG25 YG28YT5 YT14 YT15 P10 P20 M10 M20 M30 M40 V10 V20 V30 V40 Z01 Z10 Z20 Z30
