Intshayelelo:

Intsimbi yeTungsten, eyaziwa ngokuba yiCarbide eqinisiweyo, ibhekisa kwizinto ezidityanisiweyo eziqulathe ubuncinane iCarbide enye yesinyithi. ICarbide yeTungsten, iCobalt Carbide, iNiobium Carbide, iTitanium Carbide, kunye neTantalum Carbide zizinto eziqhelekileyo zentsimbi yeTungsten. Ubungakanani bengqolowa yenxalenye yeCarbide (okanye isigaba) buhlala buphakathi kwe-0.2-10 microns, kwaye iinkozo zeCarbide zibanjwa kunye kusetyenziswa iMetallic Binder. IBinder idla ngokubhekisa kwiMetal Cobalt (Co), kodwa kwezinye izicelo ezikhethekileyo, iNickel (Ni), iIron (Fe), okanye ezinye iiMetal kunye neeAlloys nazo zingasetyenziswa. Indibaniselwano yokwakheka kweCarbide kunye neBinder Phase eza kugqitywa ibizwa ngokuba "yiGrade".

Uhlu lwentsimbi ye-tungsten lwenziwa ngokwemigangatho ye-ISO. Olu hlu lusekelwe kuhlobo lwezinto ezisetyenziswayo (ezifana neeklasi ze-P, M, K, N, S, H). Ulwakhiwo lwesigaba se-binder lusetyenziswa kakhulu ngenxa yamandla alo kunye nokumelana nokugqwala.

I-matrix yentsimbi ye-tungsten inamacandelo amabini: inxalenye enye yi-hardening phase; enye inxalenye yi-bonding metal. Ii-binder metals zihlala ziintsimbi zeqela lesinyithi, ezisetyenziswa kakhulu yi-cobalt kunye ne-nickel. Ke ngoko, kukho ii-tungsten-cobalt alloys, ii-tungsten-nickel alloys kunye nee-tungsten-titanium-cobalt alloys.

Kwizinyithi ezine-tungsten, ezifana nentsimbi ekhawulezayo kunye nezinye izinyithi ezishushu ezisebenzayo, umxholo we-tungsten kwintsimbi unokuphucula kakhulu ubulukhuni kunye nokumelana nobushushu bentsimbi, kodwa ubulukhuni buya kwehla kakhulu.

Eyona ndlela iphambili yokusebenzisa izixhobo ze-tungsten yi-carbide eqinisiweyo, oko kukuthi, intsimbi ye-tungsten. I-Carbide, eyaziwa ngokuba ngamazinyo eshishini lanamhlanje, isetyenziswa kakhulu kwiimveliso zentsimbi ye-tungsten.

Ulwakhiwo lwezithako

Inkqubo yokuhluza:

Ukutshiza intsimbi ye-tungsten kukucinezela umgubo kwi-billet, uze ungene kwisithando sokutshisa ukuze sifudumale ukuya kubushushu obuthile (ubushushu bokutshiza), usigcine ixesha elithile (ixesha lokubamba), uze usipholise, ukuze ufumane izinto zentsimbi ye-tungsten ezineempawu ezifunekayo.

Amanqanaba amane asisiseko enkqubo yokusila intsimbi ye-tungsten:

1. Kwinqanaba lokususa i-arhente yokwenza kunye nokutshiza kwangaphambili, umzimba otshiziweyo udlula kolu tshintsho lulandelayo kweli nqanaba:

Ukususwa kwe-molding agent, xa ubushushu bunyuka kwinqanaba lokuqala lokusila, i-molding agent iyabola okanye iphele kancinci kancinci, kwaye umzimba osila ukhutshiwe. Uhlobo, ubungakanani kunye nenkqubo yokusila zahlukile.

Ii-oxides ezikumphezulu womgubo ziyancitshiswa. Xa kushushu ukunyibilikisa, i-hydrogen inokunciphisa ii-oxides ze-cobalt kunye ne-tungsten. Ukuba i-agent yokwenza isusiwe kwi-vacuum kwaye itshiswe, impendulo ye-carbon-oxygen ayinamandla. Uxinzelelo loqhagamshelwano phakathi kwamasuntswana omgubo luyasuswa kancinci kancinci, umgubo wesinyithi obophayo uqala ukubuyela kwimeko yesiqhelo kwaye uphinde usetyenziswe, ukusasazeka komphezulu kuqala ukwenzeka, kwaye amandla e-briquetting ayaphucuka.

2. Isigaba sokusila esiqinileyo (800℃——ubushushu be-eutectic)

Kwiqondo lobushushu ngaphambi kokuba kuvele isigaba solwelo, ukongeza ekuqhubekeni kwenkqubo yesigaba sangaphambili, impendulo yesigaba esiqinileyo kunye nokusasazwa kwayo kuyaqiniswa, ukuhamba kweplastiki kuyandiswa, kwaye umzimba osikiweyo uncipha kakhulu.

3. Inqanaba lokusila lesigaba solwelo (ubushushu obuphuma e-eutectic - ubushushu bokusila)

Xa i-liquid phase ibonakala emzimbeni osikiweyo, ukuncipha kugqitywa ngokukhawuleza, kulandele utshintsho lwe-crystallographic ukuze kwenziwe isakhiwo esisisiseko kunye nesakhiwo se-alloy.

4. Inqanaba lokuphola (ubushushu bokutshiza - ubushushu begumbi)

Kule nqanaba, ulwakhiwo kunye nokwakheka kwesigaba sentsimbi ye-tungsten kuneenguqu ezithile kwiimeko ezahlukeneyo zokupholisa. Olu phawu lungasetyenziselwa ukutshisa intsimbi ye-tungsten ukuphucula iimpawu zayo zomzimba nezoomatshini.

Intshayelelo yesicelo

Intsimbi yeTungsten yeyekhabhayithi eqinisiweyo, ekwaziwa ngokuba yi-tungsten-titanium alloy. Ubunzima bungafikelela kwi-89~95HRA. Ngenxa yesi sizathu, iimveliso zentsimbi yeTungsten (iiwotshi zentsimbi zeTungsten eziqhelekileyo) azilula ukuzinxiba, ziqinile kwaye azoyiki ukuqhoboshelwa, kodwa zibuthathaka.

Izinto eziphambili ze-carbide efakwe isamente yi-tungsten carbide kunye ne-cobalt, ezithatha i-99% yazo zonke izinto, kwaye i-1% zezinye izinyithi, ngoko ke ikwabizwa ngokuba yi-tungsten steel.

Isetyenziswa kakhulu kwi-machining echanekileyo kakhulu, izixhobo zesixhobo ezichanekileyo kakhulu, iilathe, ii-impact drill bits, ii-glass cutter bits, ii-tile cutters, eziqinileyo kwaye azisoyiki ukuqhoboshelwa, kodwa zibuthathaka. Zezesinyithi ezinqabileyo.

Intsimbi yeTungsten (i-tungsten carbide) ineempawu ezintle kakhulu ezifana nokuqina okuphezulu, ukumelana nokuguguleka, amandla alungileyo kunye nokuqina, ukumelana nobushushu kunye nokumelana nokugqwala, ngakumbi ubunzima bayo obuphezulu kunye nokumelana nokuguguleka, nokuba kubushushu obuyi-500 ℃. Ayitshintshi ngokusisiseko, kwaye isenobunzima obuphezulu kwi-1000 °C. ICarbide isetyenziswa kakhulu njengezinto, ezifana nezixhobo zokujika, izixhobo zokusika, iiplaner, iidrill, izixhobo zokubhoboza, njl.njl., zokusika isinyithi esityhidiweyo, iintsimbi ezingezizo i-ferrous, iiplastiki, iifayibha zeekhemikhali, igraphite, iglasi, ilitye kunye nentsimbi eqhelekileyo, kwaye ingasetyenziselwa ukusika intsimbi enganyangekiyo. Izinto ezinzima ukusetyenzwa ngomatshini ezifana nentsimbi eshushu, intsimbi engatyiwayo, intsimbi ephezulu ye-manganese, intsimbi yesixhobo, njl.njl. Isantya sokusika secarbide entsha efakwe isamente siphindwe kalikhulu kunesentsimbi yekhabhoni.

Intsimbi yeTungsten (iTungsten Carbide) ingasetyenziselwa ukwenza izixhobo zokubhola amatye, izixhobo zokumba, izixhobo zokubhola, izixhobo zokulinganisa, iindawo ezinganyangekiyo, izinto ezirhabaxa zesinyithi, ii-linings zesilinda, ii-precision bearings, ii-nozzles, njl.njl.

Ukuthelekiswa kwamanqanaba 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 YL10.2 YL60 YG15 YG20 YG25 YG28YT5 YT14 YT15 P10 P20 M10 M20 M30 M40 V10 V20 V30 V40 Z01 Z10 Z20 Z30

Intsimbi ye-tungsten, iimela ze-carbide eziqinisiweyo, kunye nemigangatho eyahlukeneyo ye-tungsten carbide zinezinto ezininzi ezisetyenzisiweyo, kwaye iindawo ezingenanto ziyafumaneka kwisitokhwe.
