Ukusika igesi yomshini wokusika iGesi yinkqubo yokutshisa isinyithi: okokuqala, isinyithi sishushu ngaphezu kwendawo yokutshisa i-oxy-acetylene flame, kwaye emva koko i-oksijeni ephezulu yoxinzelelo ivuliwe, isinyithi siya kutshisa ngamandla kwi-oxygen. , kunye nee-oxides eziveliswa ngumlilo zi I-oksijeni yoxinzelelo oluphezulu luvuthelwa, kwaye ubushushu obuvela ekutshiseni buqhubeka butshisa isinyithi.
Ziziphi iimfuno ezifunekayo izixhobo zokusika umatshini wokusika iGesi?
Zeziphi izilumkiso zokusebenzisa umatshini wokusika iGesi?
Uwusebenzisa njani umatshini wokusika igesi ukwenza imijelo?
Ziziphi iimfuno ezifunekayo izixhobo zokusika umatshini wokusika iGesi?
Inkqubo yokusika igesi yomshini wokusika iGesi yinkqubo yokutshisa, ukutshisa kunye nokuvuthela kwe-slag, kodwa akuzona zonke izinyithi ezinokuhlangabezana neemfuno zale nkqubo. Kuphela isinyithi esihlangabezana nale miqathango ilandelayo sinokunqunyulwa kwegesi.
1. Indawo yokutshisa isinyithi kwi-oksijini kufuneka ibe ngaphantsi kwendawo yokunyibilika kwayo;
2. Indawo yokuncibilika kwe-oxide yensimbi kufuneka ibe ngaphantsi kwendawo yokuncibilika kwesinyithi ngexesha lokusika igesi;
3. Ukutsha kwesinyithi kwi-oksijini yokusika kufuneka kube yi-reaction exothermic;
4. I-thermal conductivity yensimbi akufanele ibe phezulu kakhulu;
5. Kukho ukungcola okumbalwa kwintsimbi ethintela inkqubo yokusika igesi kunye nokuphucula ukuqina kwentsimbi.
Zeziphi izilumkiso zokusebenzisa umatshini wokusika iGesi?
Ukusika igesi kumatshini wokusika igesi ngokuqhelekileyo kusetyenziselwa kuphela intsimbi ephantsi yekhabhoni, intsimbi ephantsi ye-alloy kunye ne-titanium kunye ne-titanium alloys. Ukusika igesi yindlela esetyenziswa ngokuqhelekileyo yensimbi yokusika i-thermal kumacandelo ahlukeneyo amashishini, ngokukodwa ukusika igesi yezandla kuyaguquguquka kwaye kulula ukuyisebenzisa.
Iimeko eziphambili zokusetyenziswa komatshini wokusika iGesi, indawo yokutshisa izinto eziza kunqunyulwa iphantsi kunendawo yokunyibilika kwayo. Ukuba indawo yokutshisa iphezulu kunendawo yokunyibilika, iya kunyibilika ngaphambi kokuba ivuthe, kwaye inxalenye etyhidiweyo iya kuqhunyiswa, ukwenzela ukuba isinyithi singakwazi ukufikelela kwindawo yokutshisa. , ayinakunqunyulwa. Le yimeko yentsimbi. Indawo yokunyibilika yentsimbi enomxholo wekhabhoni ye-0.7% ilingana nendawo yokutshisa. Ukuba umxholo wekhabhoni uphezulu kuneli xabiso, ukusika igesi akunakusetyenziswa. Umxholo wekhabhoni wentsimbi etyhidiweyo yi-2% ukuya kwi-4%.
Uwusebenzisa njani umatshini wokusika igesi ukwenza iigrooves?
Sebenzisa ilangatye elikhulu, kwaye ilangatye lithambekele kancinane kwicala elisikiweyo. Yehlisa isantya.
Okokuqala, usebenzisa ipropane, ephantsi kweekhalori. Okwesibini, ilangatye alitshisi ngokuthe nkqo xa i-groove isikwa, kwaye ubushushu bomhlaba buphantsi. Okwesithathu, i-oksijini yokusika isusa ubushushu obuninzi kunokuba buvelise ngexesha lokutshisa, ukunciphisa ubushushu bomhlaba. Ngoko ke, ukufudumala okuqhubekayo, ukutshisa kunye nokuvuthela kwe-slag akunakwenzeka. Phezulu kubonakala ngathi ngumsele. Ayintle.
Ukuba ukusika okuqhubekayo, oku kuya kuthi shwaka kancinci njengoko ubushushu bentsimbi yentsimbi bunyuka ngokuthe ngcembe. Le nto inokupheliswa ngokutshisa kwangaphambili.
