Tinokuendesa kuWATT Carbide inopinza kugadzira nzvimbo paZhuzhou kuti uone magadzirirwo anoiswa. Ona kuti zvinoitwa sei!

Transcript Zvinenge zvese zvakagadzirwa nesimbi zvinogadzirwa nemuchina wekuisa. Iyo yekuisa inofanirwa kutsungirira kupisa kwakanyanya uye simba, saka inogadzirwa nezvimwe zvezvinhu zvakaomesesa pasirese.

Kuiswa kwakajairika kunogadzirwa ne80% tungsten carbide uye simbi matrix inosunga dzakaoma carbide tsanga pamwechete, uko cobalt ndiyo inonyanya kuwanda. Zvinotora anopfuura mazuva maviri kugadzira yekuisa, saka inonetsa maitiro.

Mumba yekuchengetera zvinhu, mutsara mushure memutsara wezvakagadzirwa zvakaiswa. Tungsten carbide yatinoshandisa inobva kuvatengesi vakanyatsosarudzwa; batch imwe neimwe yakaedzwa zvine hungwaru mulabhu. Mamwe mabikirwo ane zvidiki zvishoma zvezvinhu zvakasarudzwa zvinowedzerwa nemaoko. Mishonga mikuru inobva yapihwa otomatiki panzvimbo dzakasiyana-siyana dziri pedyo nemutsetse wekuyera. Muimba yekugayira zvinhu zvinogayiwa kusvika pakukura kwechidimbu chinodiwa pamwe chete ne ethanol, mvura uye organic binder.

Iyi nzira inotora kubva maawa masere kusvika ku55, zvichienderana nekubika. Slurry inopombwa mudhiri yekupfapfaidza umo gasi rinopisa renitrogen rinopfapfaidzwa kuti ribudise musanganiswa we ethanol nemvura. Kana hupfu hwaoma, hunosanganisira spherical granules ehukuru hwakafanana. Sample inotumirwa kuLab kuti itariswe kunaka. Madhiramu e100 kilograms ehupfu yakagadzirira-ku-press anosvika pamushini wekutsikirira. Binder rinowedzerwa muimba yekugaya ndiro binder rinobata hupfu pamwe chete mushure mekudzvanya.

Kusvikira ku12 matani ekumanikidza anoshandiswa, zvichienderana nerudzi rwekuisa. Binder yakawedzerwa muimba yekugaya ndiyo inobata hupfu pamwe chete mushure mekudzvanya. Iyo nzira ndeye otomatiki zvachose. Imwe neimwe inoiswa inoyerwa uye pane dzimwe nguva inodzorwa zvinoonekwa nemushandisi. Izvo zvakatsikirirwa zvinopinza zvakanyanya kusimba uye zvinoda kuomeswa muchoto chinopisa. Kuita uku kunotora maawa gumi nematatu patembiricha ingangoita 1,500 degrees Celsius. Iwo anoiswa anopinzwa muchigadzirwa chakaomesesa-samende-carbide, chakaoma sedhaimani.

Organic binder inopiswa uye chinoiswa chinodzikira kusvika pahafu yehukuru hwayo hwepakutanga. Kupisa kwakanyanya kunodzokororwa uye kushandiswa kupisa nzvimbo munguva yechando, uye kutonhora mukati mechirimo. Iwo anopinza akaiswa pasi, rimwe nerimwe, mumhando dzakasiyana dzemashini ekukuya kuti uwane iwo chaiwo saizi, geometry uye kushivirira. Sezvo simende inoisa carbide yakaoma kudaro, dhisiki rine mamiriyoni zana nemakumi mashanu emadhaimondi emuindasitiri madiki, rinoshandiswa kukuya. Iyo yakawandisa carbide inodzokororwa, pamwe nemafuta anoshandiswa sekucheka mvura.

Ruzhinji rwekuisa rwakaputirwa, kungave kuburikidza nemakemikari vapor deposition (CVD) kana yemuviri vapor deposition (PVD). Pano, tinoona PVD-maitiro. Izvo zvinoiswa zvinoiswa mumafixtures ... ... uye kuiswa muchoto. Iro rakatetepa rekupotera rinoita kuti chinopinza chiome uye chiome. Apa ndipo panowanikwawo ruvara rwayo.

Kunyangwe iyo yekuisirwa yakaongororwa murabhoritari nguva nenguva panguva yese yekuita, inoongororwa nemaoko zvakare isati yaiswa chiratidzo uye kurongedzerwa. Mushure mekunyora, mabhokisi egrey akagadzirira kutumirwa kune vanogadzira pasi rese.
