Tungsten y'umuringa
Ibisobanuro birambuye ku gicuruzwa
Ibirango by'ibicuruzwa
Ningbo De-Shin itanga ubwoko bwose bwa tungsten y'umuringa (6 ~ 50wt.% Cu) ku nganda zitandukanye. Ikoresha uburyo bwo kwinjira mu cyuma gishyushye kandi ibicuruzwa byose byujuje ibisabwa na GB / T 8320-2003, ASTM B 702-93 (Byongeye kwemezwa 2004). Tungsten y'umuringa ni iy'ibumba ryihariye kandi ifite ubushobozi bwo kudashira bwa tungsten ndetse n'amashanyarazi menshi y'umuringa.
Uburyo bwo gukora:ifu ivanze –> kanda –> sintering –> infiltration vacuum –> machining –> QC. Iyi gahunda yose yo gukora igenzurwa cyane na QC kugira ngo habeho imikorere myiza.
Ibyiza:
1. Ubudahangarwa bwinshi bw'umurambararo hamwe n'ubushobozi bwiza bwo gutwara amashanyarazi.
2. Ubushyuhe bwinshi butuma ibintu bihinduka.
3. Kwaguka k'ubushyuhe buke.
Porogaramu:
1. Gufata imiyoboro n'imiyoboro y'imyanda mu byuma bigabanya ingufu z'amashanyarazi menshi n'aciriritse cyangwa ibikoresho bigabanya imyanda.
2. Ama-electrode mu mashini zica imirasire y'amashanyarazi.
3. Icyitegererezo cy'ibicuruzwa! Ibikoresho bishyushya nk'ibintu bikonjesha bidakoresheje ibikoresho by'ikoranabuhanga n'ibikoresho byo gupfunyikamo ibikoresho by'ikoranabuhanga.
4. Ama-electrode yo gusudira uburinzi.
Ingano y'imigabane:
Inkoni ya tungsten y'umuringa: umurambararo≥0.5mm; uburebure≤300mm.
Isahani y'umuringa ya tungsten: ubugari≥1.0mm; uburebure n'ubugari≤300mm.
