Может ли графизированный нефтяной кокс способствовать будущему плавки “сверхчистой стали “?

I-graphitized petroleum coke ingadlala indima ebalulekile ekwenzeni kube lula ukuncibilikisa “insimbi ehlanzekile kakhulu” esikhathini esizayo, kanti iminikelo yayo ibonakala kakhulu ezicini ezifana nobumsulwa obuphezulu, okuqukethwe okungcolile okuphansi, ukuqina okuphezulu kwekristalu kanye nokuqina kokushisa okuphezulu, isakhiwo esinezimbobo kanye nokusebenza okuphezulu, kanye nokusetshenziswa kwayo kabanzi njengezinto zokusetshenziswa ezibalulekile. Okulandelayo ukuhlaziywa okuqondile:

Ukuhlanzeka Okuphezulu kanye Nokuqukethwe Okuphansi Kokungcola: I-graphitized petroleum coke iphathwa nge-graphitization yokushisa okuphezulu (ngokuvamile ngaphezu kuka-2500°C, ifinyelela ngisho naku-3000°C), okunciphisa kakhulu okuqukethwe kokungcola okufana ne-sulfur ne-nitrogen. Ekuncibilikisweni kwensimbi ehlanzekile kakhulu, okuqukethwe kokungcola okuphansi kubalulekile ngoba izinto ezifana ne-sulfur ne-nitrogen zingabangela amaphutha afana nokuqhekeka kanye nokuqhekeka kwensimbi, okuthinta ubumsulwa bayo kanye nokusebenza kwayo. Isici sobumsulwa obukhulu be-graphitized petroleum coke sisiza ukunciphisa ukungcola kwalokhu kungcola ensimbini, ngaleyo ndlela kuthuthukise ubumsulwa bayo.

Ukuqina Okuphezulu Kwekristalu Nokuzinza Kwezinga Lokushisa Eliphezulu: I-graphitized petroleum coke ikhombisa ukuqina okuphezulu kwekristalu, okwenza iqine kakhulu emazingeni okushisa aphezulu futhi ingathambekeli kakhulu ekushiseni nasekuwohlokeni. Ngesikhathi senqubo yokuncibilikisa insimbi ehlanzekile kakhulu, ehilela izinyathelo ezifana nokuncibilikisa nokuhlanza izinga lokushisa eliphezulu, ukuzinza okuphezulu kwe-graphitized petroleum coke kuqinisekisa ukuthi igcina ukusebenza okuzinzile kuzo zonke lezi zinqubo, ihlinzeka ngomthombo wekhabhoni othembekile wokuncibilikisa.

Isakhiwo Esinezimbobo kanye Nokusabela Okuphezulu: I-graphitized petroleum coke inesakhiwo esinezimbobo, esiza ukwandisa indawo yayo ethile kanye nokusabela kwayo. Ngesikhathi sokuncibilikisa, lesi sakhiwo esinezimbobo sikhuthaza ukuthintana okwanele kanye nokusabela phakathi kwe-petroleum coke nensimbi encibilikisiwe, sithuthukise ukusebenza kahle kokumuncwa kwekhabhoni futhi ngaleyo ndlela sikhulise ngempumelelo okuqukethwe kwekhabhoni ensimbini encibilikisiwe. Okwamanje, ukusabela okuphezulu nakho kunegalelo ekunciphiseni ukusetshenziswa kwamandla nesikhathi ngesikhathi senqubo yokuncibilikisa, kuthuthukisa ukusebenza kahle kokukhiqiza.

Ukusetshenziswa Okubanzi Njengezinto Ezibalulekile Zokusetshenziswa: I-graphitized petroleum coke ayiyona nje into ebalulekile yokusetshenziswa kwezithasiselo ze-carbon kodwa futhi isetshenziswa kabanzi ekukhiqizweni kwamabhulokhi amakhulu e-cathode, ama-electrode amakhulu e-carbon, ama-electrode amakhulu e-graphitized, kanye nama-electrode paste asebenza kahle kakhulu. Le mikhiqizo idlala indima ebalulekile enqubweni yokuncibilikisa yensimbi ehlanzekile kakhulu, njengokuhlinzeka ngokushisa okuzinzile njengezinto ze-electrode noma ukubamba iqhaza ekuphenduleni kokuncibilikisa njengezinto ezinciphisa umswakama. Ukusebenza okuhle kakhulu kwe-graphitized petroleum coke kwenza le mikhiqizo ihlangabezane nezidingo eziqinile zokusetshenziswa kwe-super clean steel smelting.
