Indlela yokuvelisa i-tungsten carbide

I-tungsten carbideYikhompawundi eyenziwe ngetungsten kunye nekhabhoni.Ukuqina kwayo kufana nedayimani.Iimpawu zayo zeekhemikhali zizinzile kwaye zithandwa kakhulu kwiinkalo ezahlukeneyo zoshishino.Namhlanje, uSidi Xiaobian uya kuthetha nawe malunga nendlela yokuvelisa i-tungsten carbide.

Ngokweemfuno zetungsten carbide rollerubukhulu, ubukhulu obuhlukeneyo be-tungsten carbide busetyenziselwa iinjongo ezahlukeneyo.Izixhobo zokusika i-Carbide, ezifana nomatshini wokusika i-blade V-shaped cutting tool, i-alloy ecocekileyo kunye ne-ultrafine subfine tungsten carbide particles.I-alloy emdaka usebenzisa i-tungsten carbide ephakathi;I-alloy ye-gravity cut and heavy cut yenziwe nge-medium coarse tungsten carbide.Ilitye elisetyenziselwa izixhobo zemigodi linobunzima obuphezulu kunye nemithwalo yempembelelo kwaye lisebenzisa i-tungsten carbide.Impembelelo encinci yamatye, umthwalo omncinci wempembelelo, kunye neqhekeza eliphakathi i-tungsten carbide njengendawo ekrwada engagugiyo;Ekugxininiseni ukuxhathisa ukunxiba, ukumelana noxinzelelo kunye nokuguda komphezulu, i-ultrafine ultrafine medium particle tungsten carbide isetyenziswa njengento eluhlaza.Isixhobo sempembelelo ikakhulu sisebenzisa i-tungsten carbide ekrwada ephakathi kunye nerhabaxa.

I-tungsten carbide inomxholo wekhabhoni we-theory ye-6.128% (i-50% ye-athomu).Xa umxholo wekhabhoni we-tungsten carbide mkhulu kunomxholo wekhabhoni yethiyori, i-carbon yamahhala ibonakala kwi-tungsten carbide.Ubukho bekhabhoni yasimahla yenza ukuba amasuntswana e-tungsten carbide akhule abe makhulu ngexesha le-sintering, okukhokelela kumasuntswana e-carbide angalinganiyo.I-Tungsten carbide ifuna ngokubanzi i-carbon carbon (≥6.07%) kunye nekhabhoni yamahhala (≤0.05%), ngelixa i-carbon iyonke ixhomekeke kwinkqubo yokuvelisa kunye noluhlu lwesicelo se-carbide ene-cemented.

Phantsi kweemeko eziqhelekileyo, ikhabhoni iyonke ye-vacuum sintering tungsten carbide ngendlela yeparafini imiselwa ikakhulu sisiqulatho esipheleleyo se-oksijini yebriquette phambi kokuba sintering.Inxalenye yomxholo we-oksijeni inyuke nge-0.75 inxalenye, oko kukuthi, i-carbon iyonke ye-tungsten carbide = 6.13% + umxholo we-oksijeni % × 0.75 (ucinga ukuba kukho umoya ongathathi hlangothi kwisithando somlilo, eqinisweni, i-carbon iyonke ye-tungsten carbide kwi uninzi lweziko lokufunxa lungaphantsi kwexabiso elibaliweyo) [4] Isiqulatho sisonke sekhabhoni yetungsten carbide yaseChina inokwahlulwa ngokwenkqubo ezintathu zeparafini.

I-vacuum sintered tungsten carbide inomxholo wekhabhoni iyonke malunga ne-6.18±0.03% (ikhabhoni yasimahla iya kwanda).Isiqulatho esipheleleyo sekhabhoni yeparafini i-hydrogen sintering tungsten carbide yi-6.13±0.03%.Isiqulatho sekhabhoni iyonke yerabha ye-hydrogen sintering tungsten carbide yi-5.90±0.03%.Ezi nkqubo ngamanye amaxesha ziyatshintshana.Ngoko ke, i-carbon content ye-tungsten carbide inqunywe ngokwemiqathango ethile.
