Emva kweminyaka engaphezu kwama-80 yophuhliso, ishishini le-calcium ye-calcium carbide liye laba lushishino olubalulekileyo lwemichiza ekrwada. Kwiminyaka yakutshanje, eqhutywa luphuhliso olukhawulezayo loqoqosho lwasekhaya kunye nemfuno ekhulayo ye-calcium carbide ezantsi, umthamo wasekhaya we-calcium carbide uye wanda ngokukhawuleza. Kwi-2012, kwakukho amashishini angama-311 e-calcium carbide e-China, kwaye umphumo wafikelela kwi-18 yezigidi zeetoni. Kwisixhobo somlilo se-calcium carbide, i-electrode yenye yezixhobo ezibalulekileyo, ezidlala indima yokuqhuba kunye nokudlulisa ukushisa. Kwimveliso ye-calcium carbide, umbane okhoyo ufaka igalelo kwisithando somlilo ngokusebenzisa i-electrode ukuvelisa i-arc, kwaye ubushushu bokumelana kunye nobushushu be-arc busetyenziselwa ukukhulula amandla (iqondo lokushisa ukuya malunga ne-2000 ° C) kwi-calcium carbide smelting. Ukusebenza okuqhelekileyo kwe-electrode kuxhomekeke kwizinto ezifana nomgangatho we-electrode paste, umgangatho weqokobhe le-electrode, umgangatho we-welding, ubude bexesha lokukhululwa koxinzelelo, kunye nobude bomsebenzi we-electrode. Ngethuba lokusetyenziswa kwe-electrode, inqanaba lokusebenza lomsebenzisi lingqongqo. Ukusebenza ngokungakhathali kwe-electrode kunokubangela ngokulula ukuphuka okuthambileyo kunye nokuqina kwe-electrode, kuchaphazela ukuhanjiswa kunye nokuguqulwa kwamandla ombane, kubangele ukuwohloka kwemeko yesithando somlilo, kwaye kubangele nomonakalo koomatshini kunye nezixhobo zombane. Ukhuseleko lobomi bomsebenzi. Ngokomzekelo, ngoNovemba 7, 2006, kwaphuka i<em>electrode ethambileyo kumzi-mveliso we<em>calcium carbide eNingxia, nto leyo eyabangela ukuba kutshiswe abasebenzi abali-12 kwindawo yexhwayelo, kuquka ukufa komntu om-1 kunye nokwenzakala okumasikizi abayi-9. Ngo-2009, ikhefu elinzima le-electrode lenzeke kwiplanti ye-calcium carbide e-Xinjiang, ebangela ukuba abasebenzi abahlanu kwindawo yesiganeko batshiswe ngokubi.
Uhlalutyo lwezizathu zekhefu elithambileyo nelinzima le-calcium carbide furnace electrode
1.Uhlalutyo lwe-Cause yekhefu elithambileyo le-calcium carbide furnace electrode
Isantya se-sintering se-electrode siphantsi kunezinga lokusetyenziswa. Emva kokuba i-electrode engacinywanga ibekwe phantsi, iya kubangela ukuba i-electrode iphuke kancinci. Ukungaphumeleli ukukhupha umqhubi wesithando somlilo ngexesha kunokubangela ukutshisa. Izizathu ezicacileyo zokuqhekeka okuthambileyo kwe-electrode zezi:
1.1 Umgangatho ombi wokunamathisela i-electrode kunye nee-volatiles ezigqithisileyo.
1.2 Icwecwe lentsimbi ye-electrode libhityile kakhulu okanye lingqindilili kakhulu. Ibhityile kakhulu ukumelana namandla amakhulu angaphandle kunye nokuqhekeka, okubangela ukuba umgqomo we-electrode ugoqeke okanye uvuze kunye nekhefu elithambileyo xa ucinezelekile; ngqindilili kakhulu ukwenza ukuba iqokobhe lentsimbi kunye nondoqo we-electrode ungadibanisi ngokusondeleyo kwaye undoqo unokubangela ikhefu elithambileyo.
1.3 Igobolondo lentsimbi ye-electrode yenziwe kakubi okanye umgangatho we-welding umpofu, obangela ukuqhekeka, okubangelwa ukuvuza okanye ikhefu elithambileyo.
1.4 I-electrode icinezelwe kwaye ibekwe rhoqo, ikhefu lifutshane kakhulu, okanye i-electrode ide kakhulu, ibangela ikhefu elithambileyo.
1.5 Ukuba i-electrode paste ayifakwanga ngexesha, indawo yokunamathisela i-electrode iphezulu kakhulu okanye iphantsi kakhulu, eya kubangela ukuba i-electrode iphule.
1.6 I-electrode paste inkulu kakhulu, ingenankathalo xa idibanisa i-paste, iphumla kwiimbambo kunye nokuba ngaphezulu, inokubangela ukuphuka okuthambileyo.
1.7 I-electrode ayifakwanga kakuhle. Xa i-electrode iyancipha kwaye emva kokuba iyancipha, okwangoku ayikwazi ukulawulwa ngokufanelekileyo, ukwenzela ukuba i-current ikhulu kakhulu, kwaye i-electrode case iyatshiswa kwaye i-electrode iyaphulwa kancinci.
1.8 Xa isantya sokunciphisa i-electrode sikhawuleza ngaphezu kwesantya se-sintering, amacandelo okunamathisela ekubunjweni abonakaliswe, okanye i-conductive elements iza kubonakaliswa, i-electrode case ithwala yonke into yangoku kwaye ivelise ubushushu obuninzi. Xa i-electrode case ishushu ngaphezu kwe-1200 ° C, amandla okuqina ayancipha ukuya kwi-Ayikwazi ukuthwala ubunzima be-electrode, ingozi ye-soft break iya kwenzeka.
Uhlalutyo lwe-2.Cause yekhefu elinzima le-calcium carbide furnace electrode
Xa i-electrode iphukile, ukuba i-calcium carbide etyhidiweyo ichithwa, umqhubi akanalo imilinganiselo yokukhusela kwaye ukungaphumeleli ukuphuma ngexesha kunokubangela ukutshisa. Izizathu ezicacileyo zokuphuka kanzima kwe-electrode zezi:
2.1 I-electrode paste ngokuqhelekileyo ayigcinwanga ngokufanelekileyo, umxholo womlotha uphezulu kakhulu, ukungcola okungaphezulu kufakwe, i-electrode paste iqulethe into encinci eguquguqukayo, i-sintering ngaphambi kwexesha okanye i-adhesion embi, ebangela ukuba i-electrode ibe nzima.
2.2 Imilinganiselo ye-electrode yokunamathisela ehlukeneyo, umlinganiselo omncinci we-binder, ukuxuba ukungalingani, amandla ama-electrode amabi, kunye ne-binder engafanelekanga. Emva kokuba i-electrode paste iyancibilika, ubukhulu beengqungquthela buya kuncipha, okunciphisa amandla e-electrode kwaye kunokubangela ukuba i-electrode iphule.
2.3 Kukho ukumka kombane okuninzi, kwaye umbane udla ngokumiswa kwaye uvulwe. Kwimeko yokungaphumeleli kwamandla, amanyathelo ayimfuneko awathathwanga, okubangela ukuqhekeka kwe-electrode kunye ne-sintering.
2.4 Kukho uthuli oluninzi oluwela kwiqokobhe le-electrode, ngakumbi emva kwexesha elide lokuvalwa, umqolo ongqindilili womlotha uya kuqokelelana kwigobolondo lentsimbi ye-electrode. Ukuba ayicocwanga emva kokuhanjiswa kwamandla, iya kubangela i-electrode sintering kunye ne-delamination, eya kubangela i-Electrode ikhefu elinzima.
2.5 Ixesha lokungaphumeleli kwamandla lide, kwaye icandelo elisebenzayo le-electrode alingcwatywanga kwintlawulo kwaye i-oxidized kakhulu, eya kubangela ukuba i-electrode ibe nzima.
2.6 I-electrodes ixhomekeke ekupholiseni ngokukhawuleza kunye nokufudumeza ngokukhawuleza, okubangela ukungafani okukhulu koxinzelelo lwangaphakathi; umzekelo, umehluko weqondo lokushisa phakathi kwee-electrode ezifakwe ngaphakathi nangaphandle kwezinto ngexesha lokugcinwa; umehluko weqondo lokushisa phakathi kwangaphakathi nangaphandle kwendawo yoqhagamshelwano inkulu; Ukufudumala okungafaniyo ngexesha lokuhanjiswa kwamandla kunokubangela ikhefu elinzima.
2.7 Ubude bokusebenza be-electrode bude kakhulu kwaye amandla okutsala makhulu kakhulu, nto leyo engumthwalo kwi-electrode ngokwayo. Ukuba utyando alukhathali, lunokubangela ikhefu elinzima.
2.8 Ubungakanani bomoya obunikezelwa ityhubhu yesibambi se-electrode incinci kakhulu okanye imisiwe, kwaye umthamo wamanzi okupholisa uncinci kakhulu, obangela ukuba i-electrode paste inyibilike kakhulu kwaye ibe njengamanzi, ibangela ukuba i-particulate carbon material iqhube, ichaphazele. amandla e-sintering ye-electrode, kunye nokubangela ukuba i-electrode iphuke nzima.
2.9 Ubuninzi be-electrode yangoku bukhulu, nto leyo enokubangela ukuba i-electrode ibe nzima.
Amanyathelo okuthintela ukunqanda ikhefu elithambileyo nelinzima le-electrode
1.Amanyathelo okuthintela ukuphepha ikhefu elithambileyo le-calcium carbide furnace

I-2.Amanyathelo okuthintela ukuphepha ikhefu elinzima le-calcium carbide furnace electrode
2.1 Bamba ngokuthe ngqo ubude bokusebenza be-electrode. I-electrode kufuneka ilinganiswe rhoqo kwiintsuku ezimbini kwaye kufuneka ichaneke. Ngokuqhelekileyo, ubude bokusebenza be-electrode buqinisekisiwe ukuba bube yi-1800-2000mm. Ayivumelekanga ukuba ibende okanye ibemfutshane kakhulu.
2.2 Ukuba i-electrode ide kakhulu, unokwandisa ixesha lokukhululwa koxinzelelo kunye nokunciphisa umlinganiselo we-electrode kwesi sigaba.
2.3 Khangela ngokuthe ngqo umgangatho we-electrode paste. Umxholo wothuthu awunakugqitha ixabiso elichaziweyo.
2.4 Khangela ngononophelo ubungakanani bokunikezelwa komoya kwi-electrode kunye nendawo yegiya ye-heater.
2.5 Emva kokungaphumeleli kombane, i-electrode kufuneka igcinwe ishushu kangangoko kunokwenzeka. I-electrode kufuneka ingcwatywe ngezinto eziphathekayo ukukhusela i-electrode kwi-oxidizing. Umthwalo awukwazi ukunyuswa ngokukhawuleza emva kokuhanjiswa kwamandla. Xa ixesha lokusilela kwamandla lilide, tshintshela kwi-Y-uhlobo lombane lokufudumala i-electrode.
2.6 Ukuba i-electrode hard breaks amaxesha amaninzi ngokulandelelana, kufuneka ihlolwe ukuba ngaba umgangatho we-electrode paste uhlangabezana neemfuno zenkqubo.
2.7 Umgqomo we-electrode emva kokufakwa kwe-paste kufuneka ugqunywe ngesiciko ukuthintela uthuli ukuba lungangeni.
2.8 Abasebenzi abenza imisebenzi yobushushu obuphezulu kufuneka banxibe izixhobo zokuzikhusela ezikwaziyo ukumelana namaqondo obushushu aphezulu kunye nokutshiza.
ukuququmbela
Ukuveliswa kwe-calcium carbide kufuneka ibe namava okuvelisa ocebileyo. Isithando ngasinye se-calcium carbide sineempawu zayo kwixesha elithile.
