Ukusikwa kwegesi yomshini wokusika igesi kuyinqubo yokushiswa kwensimbi: okokuqala, insimbi iyashiswa ngaphezu kwendawo yayo yokushisa ngelangabi le-oxy-acetylene, bese kuvulwa umoya-mpilo ophezulu, insimbi izoshisa ngamandla ku-oxygen. , kanye nama-oxide akhiqizwa ukushiswa yi-Oxygen ephezulu yokucindezela ishaywa, futhi ukushisa okuvela ekushiseni kuyaqhubeka nokushisa insimbi.
Yiziphi izimfuneko izinto zokusika zomshini wokusika iGesi ezihlangabezana nazo?
Yiziphi izinyathelo zokuphepha zokusebenzisa umshini wokusika iGesi?
Ungawusebenzisa kanjani umshini wokusika igesi ukwenza ama-grooves?
Yiziphi izimfuneko izinto zokusika zomshini wokusika iGesi ezihlangabezana nazo?
Inqubo yokusika igesi yomshini wokusika igesi iyinqubo yokushisa, ukushisa nokushaywa kwe-slag, kodwa akuzona zonke izinsimbi ezingahlangabezana nezidingo zale nqubo. Izinsimbi kuphela ezihlangabezana nemibandela elandelayo ezingasikwa igesi.
1. Indawo evuthayo yensimbi kumoya-mpilo kufanele ibe ngaphansi kunendawo yayo yokuncibilika;
2. Iphuzu lokuncibilika le-oxide yensimbi kufanele libe phansi kunephuzu lokuncibilika lensimbi ngesikhathi sokusika igesi;
3. Ukushiswa kwensimbi ekugezeni komoya-mpilo okusika kufanele kube ukusabela kwe-exothermic;
4. I-conductivity yokushisa yensimbi akufanele ibe phezulu kakhulu;
5. Kukhona ukungcola okumbalwa kwensimbi okuvimbela inqubo yokusika igesi futhi kuthuthukise ukuqina kwensimbi.
Yiziphi izinyathelo zokuphepha zokusebenzisa umshini wokusika iGesi?
Ukusika igesi komshini wokusika igesi ngokuvamile kusetshenziswa kuphela insimbi ye-carbon ephansi, insimbi ephansi ye-alloy kanye ne-titanium ne-titanium alloys. Ukusika igesi kuyindlela evame ukusetshenziswa yensimbi yokusika ezishisayo emikhakheni ehlukahlukene yezimboni, ikakhulukazi ukusika igesi ngesandla kuyaguquguquka futhi kulula ukuyisebenzisa.
Izimo eziyinhloko zokusetshenziswa komshini wokusika iGesi, indawo yokuthungela yezinto ezizonqunywa iphansi kunendawo yayo yokuncibilika. Uma iphoyinti lokuthungela liphakeme kunendawo yokuncibilika, lizoncibilika ngaphambi kokuba lishiswe, futhi ingxenye encibilikisiwe izophephuka, ukuze insimbi ingakwazi ukufinyelela endaweni yokuthungela. , ayinakunqunywa. Lokhu kunjalo nge-iron cast. Indawo yokuncibilika yensimbi enekhabhoni engu-0.7% ilingana nendawo yokuthungela. Uma okuqukethwe kwekhabhoni kungaphezulu kwaleli nani, ukusika igesi akukwazi ukusetshenziswa. Okuqukethwe kwekhabhoni yensimbi ekhonjiwe kungu-2% kuya ku-4%.
Ungawusebenzisa kanjani umshini wokusika igesi ukwenza ama-grooves?
Sebenzisa ilangabi elikhulu, futhi ilangabi litshekele kancane lapho liya khona. Yehlisa kancane ijubane.
Okokuqala, usebenzisa i-propane, ene-calorie ephansi. Okwesibili, ilangabi alishisi libheke phezulu lapho inkaba isikwa, futhi izinga lokushisa elingaphezulu liphansi. Okwesithathu, i-oxygen yokusika isusa ukushisa okungaphezu kwalokho okukhiqiza ngesikhathi sokuvutha, ukwehlisa izinga lokushisa elingaphezulu. Ngakho-ke, ukushisa okuqhubekayo, ukushisa nokushaywa kwe-slag akunakwenzeka. Phezulu kubukeka sengathi umsele. Hhayi muhle.
Uma ukusika okuqhubekayo, lokhu kuzonyamalala kancane kancane njengoba izinga lokushisa lensimbi likhuphuka kancane kancane. Lesi simo singabuye siqedwe ngokushisa kwangaphambili.
