Carbide Nozzle Scenario Chishandiso Rudzi Rudzi Kugadziriswa uye Kukosha Kuziva

Carbide nozzles zvinhu chaizvo zvinogadzirwa ne sintering hard carbide zvinhu (kunyanya tungsten carbide, WC) nemabhinda esimbi (senge cobalt, Co). Kuzvikudza kuomarara kweVickers kweanopfuura 1300 HV, yakanakisa kupfeka kuramba (10-20 yakakwira kupfuura simbi inomhanya), uye kugadzikana kwakasimba kwemafuta, zvave zvisingadzoreki mativi muzvikamu zvakaita semaindasitiri ekugadzirisa, simba, uye zvemagetsi. Kiyi yekuwedzera kukosha kwekushandisa kwavo iri mune chaiyo mamiriro-mhando yekuchinja-kufananidza iyo chaiyo nozzle mhando kune chaiwo mamiriro ekushanda kuenzanisa kuita, kusimba, uye mutengo-kubudirira.

Mune abrasive jet processing scenarios, kusanganisira jetblasting yekubvisa ngura pamusoro uye high-pressure water jet kucheka kwemaplate esimbi, madziro emukati emukati anoramba achibatwa nekudzvanywa nekumhanya-mhanya (kusvika 800 m/s) abrasive particles (semuenzaniso, alumina, silicon carbide). Nokuda kweizvi, zviyo zvakanaka-zviyo carbide nozzles (ine tungsten carbide zviyo saizi ye 0.5-1μm) ndiyo yakanakisa sarudzo. Yavo yakanyanya-dense microstructure inodzikisira kupinda kweabrasive particles, ichideredza yemukati yekupfeka kwemadziro zvakanyanya-kuwedzera hupenyu hwesevhisi ne3-5 nguva zvichienzaniswa neyekare ceramic nozzles uye kucheka pasi pekugara kutsiva downtime.

Kune akakwira-tembiricha maindasitiri senge simbi inonyungudutsa flue gasi kucheneswa uye marara ekupisa epositi kurapwa, nozzles dzinofanirwa kutsungirira kuratidzwa kwenguva refu kune 800-1000 ℃ tembiricha yakakwira ichichengetedza kugadzikana kwemhepo. Pano, tungsten-cobalt carbide nozzles (ine cobalt binder yemukati ye6% -8%) inoita zvakanyanya. Iyo cobalt binder inoumba chisungo chakatsiga netungsten carbide zviyo, kudzivirira kutsemuka kwechimiro kunokonzerwa nekupisa kwekushisa uye kuve nechokwadi chakafanana chekupfapfaidza atomization mhedzisiro, iyo yakakosha kune inoshanda flue gasi desulfurization uye kubvisa guruva.

Muminda yekuburitsa mvura chaiyo semiconductor chip kucheneswa uye LCD pani yekuputira, kunyangwe kushomeka kwemvura kunogona kutungamira kune micro-hurema (semuenzaniso, 0.1μm-chikero scratches) panzvimbo yechigadzirwa. Yakanatswa carbide nozzles-ine yemukati madziro pamusoro roughness of Ra≤0.02μm (inowanikwa kuburikidza 12-nhanho chaiyo kugaya) -kubvisa fluid eddies, zvichiita yunifomu pfapfaidzo kufukidzwa (nekutsauka kweisingasviki 5%) uye kusangana ne-ultra-high precision zvinodiwa zveindasitiri yesemiconductor.

Kunzvimbo dzemigodhi inorema (semuenzaniso, mugodhi wemarasha wepasi pevhu kudzvanywa uye kutakura zvicherwa zvepombi), mhuno inotarisana nematambudziko maviri: kudhumhana kwemagetsi kubva kumarasha/zvimedu zvematombo uye ngura kubva mumvura ine mineral-rich. Makobvu-walled carbide nozzles (aine madziro ukobvu hwe5-8mm, 2-3 nguva iyo yeakajairika nozzles) uye pamusoro anti-corrosion coating (semuenzaniso, chromium plating) kugadzirisa dambudziko iri. Ivo vanoderedza kutsiva frequency neanopfuura 60% zvichienzaniswa neakajairwa simbi nozzles, kudzikisa mari yekugadzirisa yemabhizinesi emigodhi.

Iko kukosha kwekuziva kwe carbide nozzles kunobva pane iyi yakadzika mamiriro-mhando synergy. Nekugadzirisa mafomula ezvinhu (semuenzaniso, kugadzirisa cobalt zvirimo), zvimiro zvemagadzirirwo (semuenzaniso, kukora madziro), uye kunyatsogadzirisa (semuenzaniso, Ultra-yakakwenenzverwa kupenya) kune chaiyo indasitiri inodiwa, ivo havangodzikisire mutengo wekugadzirisa ne30% -50% uye vanovandudza kugadzirwa kwehunyanzvi ne20% -30% asiwo vanotsigira tekinoroji-yepamusoro-soro. chikamu chekucheka (chinoda ma nozzles ane dimensional accuracy ye ± 0.005mm). Sezvo maindasitiri akaita sesimba idzva, semiconductors, uye aerospace achiteedzera maitiro epamusoro ekuita, mamiriro-anomisikidzwa emhando yecarbide nozzles anozowedzera kuvhura kugona kwavo, kuve mutyairi akakosha wekusimudzira maindasitiri uye kusimudzira kwemhando yepamusoro.
