Isithando somlilo se-arc kagesi

Isithando somlilo sikagesi anisithando somlilo sikagesi sokuncibilikisa insimbi nensimbi ekushiseni okuphezulu okukhiqizwa yi-electrode arc.Lapho ukukhishwa kwegesi kwenza i-arc, amandla agxila kakhulu, futhi izinga lokushisa lendawo ye-arc lingaphezu kuka-3000 ℃.Ukuze kuncibilike insimbi, isithando somlilo se-arc sikagesi sinokuguquguquka okukhulu kwenqubo kunezinye iziko zokwenza insimbi, singasusa ngokuphumelelayo ukungcola okufana nesibabule ne-phosphorus, izinga lokushisa lesithando somlilo kulula ukulawula, futhi imishini ihlanganisa indawo encane, efanelekile ukuncibilika okuphezulu- izinga i-alloy steel.

Izithando zama-arc zikagesi zingahlukaniswa ngezindlela eziningi.
Ngokusho kwefomu lokuncibilika kwe-electrode
(1) Isithando somlilo se-electric arc esingasebenziseki sisebenzisa i-tungsten noma i-graphite njenge-electrode.I-electrode ngokwayo ayidli noma idle kancane enqubweni yokuncibilikisa.
(2) Isithando somlilo se-electric arc esisebenzisekayo sisebenzisa insimbi encibilikisiwe njenge-electrode, futhi i-electrode yensimbi iyazidla yona ngenkathi incibilika.
Ngokwemodi yokulawula yobude be-arc
(1) I-arc voltage othomathikhi yokulawula isithando somlilo se-arc kagesi incike ekuqhathanisweni phakathi kwe-voltage phakathi kwezigxobo ezimbili kanye ne-voltage enikeziwe, futhi umehluko ukhuliswa isignali ukushayela i-electrode esetshenziswayo ukuthi inyuke futhi yehle, ukuze kugcinwe ugesi. ubude be-arc njalo.
(2) Ubude be-arc obungaguquki bulawula isithando somlilo se-arc sikagesi, esicishe silawule ubude be-arc obungashintshi ngokuncika ku-voltage ye-arc engashintshi.
(3) I-Droplet pulse othomathikhi elawula isithando somlilo se-arc kagesi ilawula ngokuzenzakalelayo ubude obungaguquki be-arc ngokuya ngemvamisa ye-pulse ekhiqizwa inqubo yokwakheka kwamaconsi ensimbi kanye nokuconsa kanye nobudlelwano phakathi kobude be-pulse nobude be-arc.
Ngokusho kwefomu lokusebenza
(1) Ukusebenza kwezikhathi ezithile kwesithando somlilo se-arc kagesi, okungukuthi, isithando somlilo ngasinye sokuncibilikisa sithathwa njengomjikelezo.
(2) Ukusebenza okuqhubekayo kwesithando se-arc sikagesi, esinezinhlobo ezimbili.Olunye uhlobo olujikelezayo lomzimba wesithando somlilo;Okunye ukuthi izithando zomlilo ezimbili zihlanganyela ugesi owodwa we-DC, okungukuthi, lapho ukuncibilikiswa kwesithando somlilo kuqediwe, shintsha ukunikezwa kwamandla kwesinye isithando somlilo bese uqala ukuncibilika kwesithando somlilo esilandelayo ngokushesha.
Ngokusho kwesakhiwo somzimba wesithando somlilo, singahlukaniswa sibe
(1) Isithando somlilo sikagesi esingashintshi.
(2) Isithando somlilo esijikelezayo sikagesi.
