Umunara ukoreshwa mu gusibanganya, kweza, kuwunyunyuza, kurigata hamwe nibindi bikoresho bya shimi, ibyinshi mubikoresho by umunara bigomba kuvugana na aside, alkali, umunyu, imashanyarazi kama nibindi bitangazamakuru byangirika, bityo rero birakenewe ko hagaragara ahantu hanini harwanya ruswa. muri silinderi no gufunga ibice. Nuburyo bwiza bwo kugaragara, kwambura imirongo ikoreshwa cyane mugusudira umunara wibikoresho bya shimi.
Ubuhanga gakondo bwa electrode igaragara ni tekinoroji ya arc igizwe na tekinoroji ya arc igaragara hamwe ninzibacyuho irwanya ruswa, ariko iri koranabuhanga rifite igihe kirekire cyo gukora kandi nigiciro kinini cyo gukora. Kugira ngo iki kibazo gikemuke, JingQunCo yateguye ibikoresho byo gusudira byo mu rwego rumwe (GDS-309LA yo gusudira, GXS-ED308L electroslag flux), bishobora kugera ku ngaruka ziterwa n’ibice bibiri hamwe no kugaragara gusa, kandi birashobora koroshya inzira yo kugaragara kuva kumurongo ibiri igaragara kugeza kumurongo umwe.

Porogaramu yubuhanga
1.Isuzuma ryo gusudira kubakiriya
2. Kubaka ikibanza cyabakiriya
Nyuma yimyaka yubushakashatsi niterambere, Jingqun igorofa imwe ya electroslag igaragara hejuru yo gusudira ibikoresho birahamye kandi byizewe, bifite byinshi byagezweho mubikorwa bya injeniyeri.
