Ukuveliswa kunye nokuSetyenziswa kweCemented Carbide Crushed Grits
Imveliso kunyeAisicelo seI-Cemented Carbide iGrits etyumkileyo
Inkqubo yokuvelisa i-carbide echotshoziweyo iquka iinkqubo ezimbini: ukutyumza kunye nokuhlola.
Okokuqala, aukutyunyuzwa kwe-lloy kunokwahlulwa zibe ziindlela ezimbini: ukutyunyuzwa ngesandla kunye nokutyumzwa ngoomatshini.
1. I-alloy i-waste hard alloy ishushu ngaphezu kwe-800 ° C kwisithando somlilo nge-manual crushing method, kwaye ifakwe ngokukhawuleza emanzini ukuze ipholile, ukwenzela ukuba i-carbide ene-cemented cracks. I-carbide eqhekekileyo ke icudiswe ngaphakathi kwintsimbi yentsimbi.
2. Mechanical crushing method ukutyunyuzwa ngoomatshini kunokusetyenziswa njengesityumzi esando okanye isityumzi. Kungcono ukhethe izityuli ezimbini zokutyumba kulo msebenzi, esinye senziwa ngokuqhawuka ngokurhabaxa, esinye saphule kakuhle. Ukutshintsha umgama phakathi kwee-roller ezimbini ze-roller crusher, unokwenza lo msebenzi unzima, itafile enye ukwenza ukwaphuka okurhabaxa, enye ukwenza ukwaphuka kakuhle. Ukutshintsha umgama phakathi kwee-roller ezimbini ze-roller crusher, unokwenza lo msebenzi unzima, itafile enye ukwenza ukwaphuka okurhabaxa, enye ukwenza ukwaphuka kakuhle. Ukutshintsha i-pitch phakathi kwee-roller ezimbini ze-roll crusher, i-carbide ene-cemented ingaphulwa ibe ngamacandelo ahlukeneyo okuziinkozo kwimveliso.
Si-econ, ukuhluzwa kunye nokuhlelwa.
Isixa esincinci seemveliso ezaphukileyo ngesandla zihluzwa ngesampulu eqhelekileyo yesikrini.Ukuveliswa kobuninzi benani elikhulu leemveliso zokusebenzisa isikrini sokungcangcazela ngoomatshini.Ukuba isikrini sokungcangcazela esine-five-layer sikhethiwe, imveliso inokujongwa kwiintlobo ezintlanu zobukhulu bamasuntswana ngexesha elinye. Iimilimitha ze-coarse grained cemented carbide zinokuhlelwa ngesikrini sesandla sentsimbi engenasici.Ipleyiti yensimbi engenastainless enobunzima obuyi-2 mm idityaniswe kwipleyiti engekho nzulu, kwaye eminye imingxunya igrunjwa kwipleyiti engekho nzulu ngokoluhlu oluthile lwesayizi yesuntswana ukuze ibe yimilimitha erhabaxa yesikrini.
Uluhlu oluhlukeneyo lobungakanani be-granular cemented carbide, ukusetyenziswa kwayo kuyahluka.Okulandelayo ndiza kuthetha malunga nosetyenziso lwegranular carbide kuluhlu lobungakanani bamasuntswana ahlukeneyo. Kuya kubakho izicelo ezilishumi zizonke.
1. Izixhobo zokomba zeJoloji
I-Carbide composite welding rod yenziwe nge-carbide etyunyuziweyo kunye nobukhulu be-3 ~ 5 mm kunye nobhedu okanye isinyithi sesiseko sokuzalisa isinyithi, kwaye intonga ye-welding inyuswe kumlebe we-drill bit kunye ne-oxygen acetylene flame ukwenza i-geological drill core drill.Ngale ndlela, i-drill bitana edityanisiweyo ingagrumba ibe yi-5 ~ 6 ephakathi kolwakhiwo lwamatye, kwaye iphucule ukusebenza kakuhle kwamaxesha angama-2 ~ 3 kune-drill bit enamazinyo adityanisiweyo e-carbide, kwaye ukusetyenziswa kwe-carbide sisinye kwishumi kuphela bit drill jikelele. Olu hlobo lwe-geological drill ene-carbide surfacing welding etyumkileyo inefuthe lokuzilola.
2.Well ukuzinzisa
I-carbide powder eyenziwe ngesamente eyaphukileyo ngoomatshini ixutywe kunye nomthamo ofanelekileyo wokuguquguquka kwaye ifakwe kwityhubhu yentsimbi ye-08 yokwenza iintonga ze-welding, kwaye intonga ye-welding iphezu kwebar ye-oyile ye-stabilizer, ephucula kakhulu ubomi benkonzo. isizinzisi. Ubomi benkonzo ye-oil well stabilizer bunyuka ngamaxesha angama-2 kunye namaxesha angama-10, ngokulandelanayo. Ubomi benkonzo ye-stabilizer surfacing nge-cemented cemented carbide yi-1 ixesha elide kune-cast tungsten carbide electrode, kunye namaxesha angama-15 ngaphezu kwe-cobalt chromium tungsten electrode.
3. Imathiriyeli yomzimba wesuntswana ledayimane lokubhola
Kwilizwe lethu, izinto zomzimba we-diamond drill zihlala ziphosa i-tungsten carbide. Ukusukela ngo-1985, iNorth China Petroleum Administration ibisenza i-tungsten carbide njengesixhobo somzimba wedayimane kwilizwe lethu. Zininzi iingenelo zokusebenzisa i-WC-Co i-particle alloy njengesixhobo somthunzi. Xa kuthelekiswa nokuphosa i-tungsten carbide, i-carbide etyumkileyo yomelele ngakumbi kumdibaniso wedayimane, idityaniswe ngokusondeleyo nomzimba wentsimbi, kwaye i-drill igudile kwaye intle emva komatshini.
4. Izixhobo zokuloba kunye nezixhobo zokusila
Intonga ye-welding yenziwe nge-carbide etyumkileyo kunye ne-elastic nickel yesilivere ye-alloy filler metal, kwaye emva koko ijonge kwi-oyile yokuloba kunye nezixhobo zokugaya nge-oxyacetylene flame, edlala indima enkulu kakhulu ekwembeni kweoli.
5. Dip i-surfacing ye-blast furnace bell
Intsimbi yesithando somlilo ihlala iphantsi kwe-friction ye-iron ore, i-coke kunye ne-limestone, kwaye ukunxiba kubi kakhulu. Kwixesha elidlulileyo, i-chromium ephezulu yentsimbi yentsimbi ye-welding isetyenziselwe ukunciphisa ukunxiba kwentsimbi. Intsimbi yesithando somlilo kunye nobubanzi beemitha ezi-5 kunye nomthamo we-cubic metres ye-5000 ifakwe kwaye iphezulu nge-carbide enesamente. Ubomi benkonzo yentsimbi yesithando somlilo esijongene nale ndlela yi-3 ~ 8 ixesha elide kunolo kunye ne-electrode yentsimbi ephezulu ye-chromium.
6. Incakuba yesarha engenamazinyo
Le blade yesarha ayinayo i-serration, kwaye isiphelo sayo senziwe ngamasuntswana angenakubalwa e-carbide enesamente edityaniswe kwiphepha lesixhobo sentsimbi. Le blade isarha ibukhali kwaye inokusika izinto ezininzi ezinzima kakhulu, ngokufanelekileyo nangoqoqosho.
7. Juba intloko yehamile kunye nebhola yentsimbi
I-carbide echotshoziweyo ene-cemented isasazwa kwi-mold casting, insimbi etyhidiweyo ifakwe kwaye i-carbide echotshoziweyo edibeneyo idibaniswe kunye nokuphosa ubukhulu obuhlukeneyo bejometri yeendawo ezinqabileyo zokunxiba. Olu hlobo lweendawo ezityhidiweyo kunye nezakhiweyo - ngokubanzi zisebenzisa i-20 ~ 30 okanye i-40 ~ 60 ye-mesh ye-granular cemented carbide, i-cast kunye ne-inlaid ngentsimbi yentsimbi kungcono ukusebenzisa i-manganese steel.
8. Imathiriyeli ehlanganisiweyo ye-Carbide enesamente
Umgubo ocoliweyo we-WC-Co wealloy kunye nomgubo wentsimbi zixutywe ngokulinganayo, zicinezelwe kwaye zitshiswe, kwaye emva koko zifakwe kwi-alloy yobhedu ukwenza izinto ezidibeneyo. Izixhobo ezinqabileyo zokunxiba ezenziwe ngolu hlobo zineempawu ezintle zoomatshini kunye nokuxhatshazwa kokugqoka.
9. Ukumelana nokunxiba okuphezulu
I-coarse crystal WC powder kunye ne-WC-CO granular alloy zixutywe ngokulinganayo kumlinganiselo we-60:40, zigqunywe kumzimba othwele intsimbi, ze emva koko zifakwe kwisiseko sentsimbi yobhedu, kwaye zenziwe ngoomatshini ukuze zibe yintsimbi enokumelana nokunxiba okuphezulu.
10.Thermal spray welding izigaba nzima izongezo
Itekhnoloji ye-thermal ye-welding ye-self-fluxing alloy powders efana nentsimbi, i-nickel kunye ne-cobalt ikwi-ascendant. Kwezi ntlobo zingasentla ezahlukeneyo zokuzixuba ingxubevange yomgubo, yongeza inani elithile le-150-320 i-mesh granular cemented carbide powder, kwaye emva koko utshize i-welding, ngenxa yamasuntswana e-carbide asasazwe kumaleko we-welding wokutshiza, ukuxhathisa kokutshiza kwe-welding layer. yande kakhulu. Ngokomzekelo, i-fan exhaust blade eyenziwe nge-medium carbon steel ingasetyenziselwa iinyanga ezi-4 kuphela, kwaye ubomi benkonzo bunyuswa ukuya kwiinyanga ze-16 emva kwesitofu samalahle kunye ne-nickel-based self-fusing alloy powder kunye ne-50% etyumkileyo ye-carbide powder. I-scraper ye-alloy ephantsi yomxube wensimbi, ubomi bokuqala buyienyanga ezi-2 kuphela, kwaye ubomi benkonzo bandiswa kwiinyanga ezili-12 emva kokutshiza i-welding kunye ne powder engentla.
Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluninzi kunye neenkcukacha, unakoQHAGAMSHELANA NATHIngefowuni okanye ngeposi ekhohlo, okanyeSITHUMELE imeyileemazantsi thisiphepha.
