Intonga ye-tungsten ye-carbide yi-tungsten carbide bar bar, ekwabizwa ngokuba yi-tungsten steel bar, kulula ukuyithetha, i-tungsten steel bar engqukuva okanye i-tungsten carbide bar bar.I-Tungsten carbide yinto edibeneyo eveliswa ngumgubo wesinyithi kwaye yenziwe ngamacandelo esinyithi esichasayo (isigaba esinzima) kunye neentsimbi ezidibeneyo (isigaba se-binder).
Kukho iindlela ezimbini zokwenza ukuveliswa kwe-tungsten carbide imivalo ejikelezayo: enye i-extrusion, kunye ne-extrusion yindlela efanelekileyo yokuvelisa imivalo emide.Inokunqunyulwa kuyo nayiphi na ubude obufunwa ngumsebenzisi ngexesha lenkqubo ye-extrusion.Nangona kunjalo, ubude bubonke abunakudlula i-350mm.Enye i-compression molding, yindlela efanelekileyo yokuvelisa isitokhwe esifutshane sebha.Njengoko igama libonisa, umgubo we-carbide owenziwe ngesamente ucinezelekile ube ngumbumba.
I-carbide ene-cemented inoluhlu lweepropati ezibalaseleyo ezifana nobunzima obuphezulu, ukuxhathisa ukunxiba, ukomelela okulungileyo kunye nokuqina, ukumelana nobushushu, ukuxhathisa ukubola, ngokukodwa ubunzima bayo obuphezulu kunye nokumelana nokunxiba, okuhlala kungatshintshi nakwiqondo lobushushu le-500 ° C, kwaye kunjalo. inobunzima obuphezulu kwi-1000 °C.I-tungsten carbide isetyenziswa ngokubanzi njengezixhobo zesixhobo, ezifana nezixhobo zokujika, abasiki bokungqusha, abasiki beplani, iidrili, abasiki abakruqulayo, njl.njl., ukusika intsimbi, iintsimbi ezingezizo intsimbi, iiplastiki, imicu yemichiza, igraphite, iglasi, ilitye kunye nesiqhelo. intsimbi, kwaye ingasetyenziselwa ukusika intsimbi ukumelana nobushushu, intsimbi, intsimbi ephezulu manganese, isixhobo sentsimbi kunye nezinye izinto ezinzima zokusila ezimanzi (ilitye lokusila, ikhabhathi yokomisa, i-Z-mixer, igranulator---), ukucinezela (ngecala uxinzelelo lwe-hydraulic press okanye i-extruder), --- i-sintering (isithando somlilo, isithando somlilo esidibeneyo okanye i-HIP yoxinzelelo oluphantsi lomlilo).
Izinto eziluhlaza zisila ngokumanzi, ukomisa, i-glue doping, emva koko ukomisa kunye nokunciphisa uxinzelelo emva kokubunjwa okanye ukukhutshwa, kwaye ekugqibeleni wenze i-alloy yokugqibela engenanto ngokudibanisa kunye ne-sintering.
Ukungalungi kwemveliso ye-bar extrusion ejikelezayo kukuba umjikelo wemveliso ude.Ukucudisa imivalo emincinci ejikelezayo engaphantsi kwe-3mm kunye nokuphula iziphelo ezimbini kuya kuchitha inani elithile lezinto.Ubude obude be-carbide encinci yebhayibhile ejikelezayo, imbi ngakumbi ukuthe tye kwe-blank.Ngokuqinisekileyo, iingxaki ezithe tye kunye nokujikeleza zinokuphuculwa ngokusila kwi-cylindrical kwixesha elizayo.
Enye i-compression molding, yindlela yokuvelisa isitokhwe esifutshane sebha.Njengoko igama libonisa, sisingundo esicinezela i-carbide powder eyenziwe ngesamente ibe yimilo.Inzuzo yale ndlela yokwenza ibha ye-carbide kukuba inokubunjwa kwipasi enye kwaye iyancipha i-scrap.Yenza lula inkqubo yokusika ucingo kunye nokuphelisa umjikelo wezinto ezomileyo zendlela yokukhupha.Eli xesha lifutshane lingasentla linokugcina abathengi iintsuku ezi-7-10.
Ukuthetha ngokuthe ngqo, ucinezelo lwe-isostatic lukwakwindlela yoxinzelelo.Ukucinezela kwe-Isostatic yeyona ndlela ifanelekileyo yokwenza imveliso yee-tungsten carbide round bar.Ngokusebenzisa izitywina zepiston eziphezulu kunye nezantsi, ipompo yoxinzelelo ifaka i-liquid medium phakathi kwe-cylinder yoxinzelelo oluphezulu kunye ne-rubber ecinezelekileyo, kwaye uxinzelelo luhanjiswa ngerabha ecinezelweyo ukwenza i-cemented carbide powder icinezele ukwenza.
