UHP Graphite electrode
Kev piav qhia
Ultra-high-power graphite electrodes yog ua los ntawm high-zoo koob coke raws li lub ntsiab raw khoom, thiab yog tsim los ntawm kev sib sau, roasting, impregnating, graphitizing thiab mechanical processing.Lawv tau siv dav hauv hluav taws xob arc rauv ua cov khoom siv hluav taws xob.
Specification
Lub cev thiab tshuaj indexes ntawm Ultra-siab zog graphite electrodes thiab txiv mis xa mus rau YB / T 4090-2015
Cov lus qhia ntawm graphite electrode
1.Electrodes yuav tsum tau muab cia rau hauv qhov chaw huv si, qhuav, kev poob siab thiab kev sib tsoo kom tsis txhob muaj kev sib tsoo.Nws yuav tsum tau qhuav ua ntej siv.
2.Thaum txuas lub txiv mis, ntxuav lub qhov nrog compressed cua, ces ntsia hlau lub txiv mis rau hauv nws carfully tsis ua puas lub theads.
3.Ua rau lub taub hau electrode los ntawm cov cua compressed thaum ob lub electrodes yog 20-30mm deb.
4.Thaum cov electrodes txuas nrog lub wrenches, nws yuav tsum tau nruj nruj rau lub lacation teev tias qhov sib txawv ntawm ob lub electrodes yog tsawg dua 0.005mm.
5. Kom tsis txhob muaj cov electrode breakage, thov kom deb ntawm cov ntaub ntawv qhia blocks.
6. Txhawm rau kom tsis txhob muaj cov electrode tawg, tso lub aniseed block rau hauv qab thiab teem lub me me thaiv rau sab sauv.
