Umehluko phakathi kwesithando somlilo esincibilikisa induction kanye nesithando somlilo se-arc kagesi, yikuphi ukwenza insimbi okungcono? Ubuhle nobubi? …
1. Izici mayelana nekhono lokucwenga
Izithando ze-arc zikagesi zingcono kunezifutho zokuncibilika zokungeniswa ngokwemibandela yokususwa kwe-phosphorus, isulfure nomoya-mpilo.
2. Izinga eliphezulu lokubuyisela kabusha izakhi ze-alloy ezincibilikisiwe
Isivuno sama-elementi e-alloying ancibilikisiwe ngesithando somlilo esincibilikisayo singaphezulu kwalokho kwesithando somlilo se-arc sikagesi. Ukulahleka kwe-volatilization kanye ne-oxidation yezakhi kukhulu ngaphansi kwezinga lokushisa eliphezulu le-arc. Izinga lokulahlekelwa okushisayo kwezakhi ze-alloy ngesikhathi sokuncibilika esithandweni sokuncibilika sokungeniswa liphansi kunalelo lesithando somlilo se-arc kagesi. Ikakhulukazi, izinga lokulahlekelwa okuvuthayo kwezakhi ze-alloy ezintweni ezibuyayo ezilayishwe isithando somlilo liphakeme kakhulu kunalelo lesithando somlilo esincibilikayo. Ekuncibilikiseni kwesithando somlilo se-induction, singabuyisa ngempumelelo izakhi ze-alloying ezintweni ezibuyayo. Ngesikhathi sokuncibilika kwesithando somlilo se-arc kagesi, izakhi ze-alloying ezintweni zokubuyisela kuqala zifakwe i-oxidized zibe yi-slag, bese zincishiswa kusukela ku-slag kuya ensimbi encibilikisiwe, futhi izinga lokulahlekelwa okuvuthayo landa kakhulu. Izinga lokutholwa kwento yengxubevange yesithando somlilo sokungeniswa siphezulu kakhulu kunaleso somlilo we-arc kagesi lapho okubuyiswayo kuncibilikiswa.
3. Ukwanda kwekhabhoni ephansi ensimbi encibilikisiwe ngesikhathi sokuncibilika
Isithando somlilo se-induction sincike kumgomo wokushisisa okufakwayo ukuze kuncibilike ukushaja kwensimbi ngaphandle kokukhuphuka kwekhabhoni yensimbi encibilikisiwe. Isithando somlilo se-arc sikagesi sincike kuma-electrode egraphite ukushisisa ukushaja nge-arc kagesi. Ngemva kokuncibilika, insimbi encibilikisiwe izokwandisa ikhabhoni. Ngaphansi kwezimo ezijwayelekile, lapho kuncibilika insimbi ye-high-alloy nickel-chromium, ubuncane bekhabhoni yokuqukethwe kwekhabhoni ekuncibilikiseni kwesithando somlilo se-arc ngu-0.06%, futhi ekuncibilikeni kwesithando somlilo esincibilikayo, kungafinyelela ku-0.020%. Ukwenyuka kwekhabhoni kunqubo yokuncibilikisa i-arc yomlilo kagesi kungu-0.020%, kanti lokho kwesithando somlilo esincibilika ku-0.010%.
4. I-electromagnetic stirring yensimbi encibilikisiwe ithuthukisa izimo ze-thermodynamic neziguquguqukayo zenqubo yokwenza insimbi Izimo zokunyakaza kwensimbi encibilikisiwe esithandweni sokuncibilika se-induction zingcono kunalezo zesithando somlilo se-arc kagesi. Isithando somlilo se-arc kagesi kumele sifakwe isivusivunguvungu sikagesi esine-low-frequency electromagnetic stirrer kule njongo, futhi umphumela waso awukabi muhle njengesithando somlilo esincibilikayo.
5. Imingcele yenqubo yenqubo yokuncibilikisa kulula ukuyilawula. Izinga lokushisa, isikhathi sokucwenga, ukuqina okushukumisayo kanye nokushisa okungaguquki kwesithando somlilo sokuncibilika ngesikhathi sokuncibilika konke kulula kakhulu kuneziko likagesi ze-arc futhi kungenziwa nganoma yisiphi isikhathi. Ngenxa yezici ezishiwo ngenhla zesithando somlilo esincibilikayo, sithatha isikhundla esibalulekile ekuncibilikisweni kwezinsimbi nama-alloys ane-alloy ephezulu.
