Nau'in Nau'in Aikace-aikacen Samar da Ƙimar Nozzle da Gane Ƙimar Carbide Nozzle

Carbide nozzles daidaitattun abubuwan da aka yi su ne ta hanyar sarrafa kayan carbide mai wuya (musamman tungsten carbide, WC) tare da masu ɗaure ƙarfe (kamar cobalt, Co). Yin alfahari da taurin Vickers sama da 1300 HV, kyakkyawan juriya na lalacewa (sau 10-20 sama da ƙarfe mai sauri), da kwanciyar hankali mai ƙarfi, sun zama sassa masu mahimmanci a sassa kamar sarrafa masana'antu, makamashi, da lantarki. Makullin haɓaka ƙimar aikace-aikacen su yana cikin daidaitaccen daidaita nau'in yanayi-wanda ya dace da nau'in bututun ƙarfe mai kyau zuwa takamaiman yanayin aiki don daidaita aiki, dorewa, da ingancin farashi.

A cikin al'amuran sarrafa jet na abrasive, gami da fashewar sandblasting don cire tsatsa mai tsatsa da matsanancin ruwa jet yankan faranti na ƙarfe, bangon bututun ciki yana ci gaba da tasiri kuma yana lalata ta da sauri mai sauri (har zuwa 800 m / s) barbashi abrasive (misali, alumina, silicon carbide). Don wannan, nozzles carbide na hatsi mai kyau (tare da girman ƙwayar tungsten carbide na 0.5-1μm) shine mafi kyawun zaɓi. Matsakaicin ƙananan ƙananan ƙananan su yana rage yawan shigar da barbashi masu ɓarna, yana rage yawan lalacewa na bangon ciki sosai-ƙara rayuwar sabis ta sau 3-5 idan aka kwatanta da nozzles na yumbu na gargajiya da kuma yanke saukowa akai-akai.

Domin high-zazzabi masana'antu al'amurran da suka shafi kamar karfe smelting flue gas tsarkakewa da sharar gida incineration shaye jiyya, nozzles dole jure dogon lokacin da daukan hotuna zuwa 800-1000 ℃ high yanayin zafi yayin da rike airflow kwanciyar hankali. Anan, tungsten-cobalt carbide nozzles (tare da abun ciki na cobalt na 6% -8%) suna yin kyau sosai. Cobalt mai ɗaure yana samar da tabbataccen haɗin gwiwa tare da hatsin tungsten carbide, yana hana fashewar tsarin da ya haifar da girgizar zafi da kuma tabbatar da daidaitaccen tasirin atomization na feshi, wanda ke da mahimmanci don haɓakar iskar gas mai inganci da cire ƙura.

A cikin daidaitattun filayen isar da ruwa kamar tsabtace guntu na semiconductor da murfin panel LCD, ko da ƙaramin tashin hankali na ruwa na iya haifar da lahani (misali, 0.1μm-sikelin sikelin) akan saman samfuran. Nozzles carbide da aka goge-tare da ƙarancin bango na ciki na Ra≤0.02μm (wanda aka samu ta hanyar madaidaicin mataki na 12) - kawar da eddies na ruwa, yana ba da damar ɗaukar hoto na uniform (tare da karkatacciyar ƙasa da 5%) da saduwa da matsananciyar madaidaicin buƙatun masana'antar semiconductor.

Don wuraren hakar ma'adinai masu nauyi (misali, ma'adinan ma'adinan da ke ƙarƙashin ƙasa da kuma jigilar bututun ma'adinai), nozzles suna fuskantar ƙalubale biyu: karo na inji daga gutsuttsuran kwal/dutse da lalata daga ruwa mai wadatar ma'adinai. Ƙaƙƙarfan ƙwayar carbide mai kauri (tare da kauri na bango na 5-8mm, sau 2-3 na daidaitattun nozzles) da kuma rufin anti-lalata (misali, chromium plating) warware wannan matsala. Suna rage mitar sauyawa da sama da 60% idan aka kwatanta da na yau da kullun na nozzles na karfe, rage farashin kulawa don kamfanonin hakar ma'adinai.

Fahimtar ƙimar nozzles na carbide ya samo asali ne daga wannan haɗin gwiwar nau'in yanayi mai zurfi. Ta hanyar keɓance samfuran kayan aiki (misali, daidaita abun ciki na cobalt), ƙirar tsarin (misali, bangon kauri), da ingantaccen aiki (misali, polishing mai kyau) zuwa takamaiman buƙatun masana'antu, ba wai kawai rage farashin kulawa da 30% -50% ba da haɓaka haɓakar samarwa ta hanyar 20% -30n-ƙarshen fashewar fasaha amma har ma da goyan bayan fage mai ƙarfi. Yanke bangaren injin sararin samaniya (yana buƙatar nozzles tare da daidaiton girman ± 0.005mm). Kamar yadda masana'antu kamar sabon makamashi, semiconductor, da sararin samaniya suna bin matakan aiki mafi girma, daidaita yanayin yanayi na nozzles na carbide zai ƙara buɗe yuwuwar su, zama babban direba don haɓaka masana'antu da haɓaka mai inganci.
