Ziziphi iingenelo ezipheleleyo kwezoqoqosho ezinokuziswa kumashishini kusetyenziso lwe-graphitized petroleum coke carbon additive esemgangathweni ophezulu?

Ukusetyenziswa kwe-graphitized petroleum coke recarburizers ezikumgangatho ophezulu kunokuzisa amashishini iingenelo ezipheleleyo zoqoqosho kwiinkalo ezininzi, kubandakanya ukunciphisa iindleko zemveliso, ukuphucula umgangatho wemveliso, ukuphucula ukusebenza kakuhle kwemveliso, kunye nokuphucula iingenelo zokukhusela okusingqongileyo. Uhlalutyo oluthile lulandelayo:

I. Ukunciphisa Iindleko Zemveliso Nokuphucula Ukusetyenziswa Kwezinto Ezisetyenzisiweyo

Ukunciphisa Ukusetyenziswa kweNsimbi yeHagu: Ii-recarburizer ze-petroleum coke ezisemgangathweni ophezulu, ezibonakaliswa ngumxholo wekhabhoni ozinzileyo ophezulu (ngesiqhelo i-≥98%) kunye nokungcola okuphantsi, zinokuthatha indawo yomthombo wekhabhoni kwintsimbi yehagu. Ngokwedatha yeshishini, ukusebenzisa le recarburizer kunokunciphisa ukusetyenziswa kwentsimbi yehagu nge-20%-40%, kunciphisa iindleko ngetoni nganye yee-castings malunga ne-300-500 yuan. Umzekelo, ishishini lokwakha izinto zokwenziwa ligcine ngaphezulu kwesigidi se-yuan kwiindleko zokuthengwa kwentsimbi yehagu ngonyaka ngokuphucula umlinganiselo we-recarburizer.

Ukuphucula Izinga lokuFunxa: Unyango lweGraphitization luvumela iiathom zekhabhoni ukuba zenze isakhiwo esicwangcisiweyo, nto leyo enyusa izinga lokufunxa ukusuka kwi-60% yee-recarburizers eziqhelekileyo ukuya kwi-90%-95%. Oku kuthetha ukuba kufuneka i-recarburizer encinci ukuze kufikelelwe kumxholo wekhabhoni ekujoliswe kuwo, nto leyo enciphisa iindleko zezinto. Umzekelo, ekwenzeni intsimbi ye-arc furnace yombane, ukongeza i-0.1%-0.3% ye-recarburizer eyenziwe ngegraphitized kunokulungisa umxholo wekhabhoni kwintsimbi enyibilikisiweyo ngelixa kunciphisa ixesha lokunyibilikisa ngemizuzu eli-15-20 kunye nokunciphisa ukusetyenziswa kwamandla.

II. Ukuphucula uMgangatho weMveliso kunye nokuphucula uKhuphiswano kwiMarike

Ukuphucula Ukusebenza Kokuphosa: Ii-microcrystals ze-graphite kwi-graphitized petroleum coke recarburizers ezikumgangatho ophezulu zingasebenza njenge-crystallization nuclei, zikhuthaza ukukhula okufanayo kwee-graphite flakes kwi-cast iron. Kwi-grey cast iron, oku kunokunyusa amandla okutsalwa nge-15%-25%; kwi-ductile iron, kunokuphucula ukuxinana nge-10%-20%. Umzekelo, emva kokutshintshela kule recarburizer, umenzi weebhloko zesilinda seenjini zeemoto unciphise izinga lokusilela kokuphosa ukusuka kwi-15% ukuya kwi-3%, nto leyo ephucula kakhulu isivuno semveliso.

Ukuhlangabezana neemfuno eziphezulu: Iimpawu zesalfure ephantsi (≤0.05%) kunye nenitrogen ephantsi (≤400ppm) zenza ukuba i-graphitized petroleum coke recarburizers zibe zizixhobo ezibalulekileyo zokuvelisa i-castings yeemoto eziphezulu, izixhobo zamandla omoya, kunye nezinye izinto ezibalulekileyo. Ukusebenzisa le recarburizer kunokuthintela iziphene ze-cast ezifana nokuqhekeka kunye nokuqhekeka okubangelwa bukungcola kwesalfure kunye ne-nitrogen, okunyusa ixabiso lemveliso.

III. Ukuphucula ukusebenza kakuhle kwemveliso kunye nokunciphisa imijikelo yemveliso

Ukwandisa Isantya Sokunyibilikisa: Ngexesha lokwenza intsimbi, ii-recarburizer ze-petroleum coke ezikumgangatho ophezulu ezisemgangathweni zinokunyibilikisa ngokukhawuleza kwaye zisasazeke ngokulinganayo, nto leyo enciphisa ixesha lokunyibilikisa. Umzekelo, i-steel mill yanciphisa umjikelo wayo wokunyibilikisa i-electrical arc furnace nge-15%-20% emva kokusebenzisa le recarburizer, nto leyo eyandisa imveliso yentsimbi yonyaka ngaphezulu kweetoni ezili-10,000.

Ukuzinzisa Iinkqubo Zemveliso: Ubunyulu obuphezulu kunye nokungcola okuphantsi kwe-recarburizer kuthintela i-oxidation kunye nokuwohloka kumaqondo obushushu aphezulu, kunciphisa ukuguquguquka kwemveliso. Umzekelo, ekubunjweni okuqhubekayo, ukusebenzisa le recarburizer kunokugcina umxholo wekhabhoni ozinzileyo kwisinyithi esinyibilikisiweyo, kuthintelwe imiba yomgangatho wokubunjwa okubangelwa kukuguquguquka komxholo wekhabhoni.

IV. Ukuphucula iiNzuzo zoKhuseleko lweNdalo kunye nokuhlangabezana neemfuno zoPhuhliso oluZinzileyo

Ukunciphisa Ukukhutshwa Kokungcola: Iimpawu zesalfure ezisezantsi kunye nenitrogen ephantsi ze-graphitized petroleum coke recarburizers zinciphisa kakhulu ukukhutshwa kwe-sulfur dioxide kunye ne-nitrogen oxides ngexesha lokutsha. Umzekelo, emva kokusebenzisa le recarburizer, i-foundry yanciphisa iindleko zayo zokukhupha i-flue gas desulfurization ngama-40% kwaye yanciphisa ukukhutshwa kwe-sulfur dioxide yonyaka ngama-toni amaninzi.

Ukukhuthaza ukuHlaziya izixhobo: Ngexesha lokuveliswa kwee-recarburizers ze-petroleum coke ezifakwe i-graphitized, ubushushu obumdaka bungafunyanwa ukuze kuvelise umbane, kongiwe i-300 kWh yombane ngetoni nganye yemveliso. Ukongeza, igesi yomsila inganikezelwa kwamanye amacandelo emizi-mveliso (njengezityalo ze-ceramic) njengepetroli, nto leyo efezekisa ukusetyenziswa kakuhle kwezixhobo. Umzekelo, ngemodeli yezoqoqosho olujikelezayo, ipaki ye-eco-industrial inciphise ukukhutshwa kwekhabhoni nge-1.2 yeetoni ngetoni nganye ye-recarburizer eveliswayo.
