Uhlalutyo lwenzuzo yezixhobo zokufudumeza eziqhubekayo ze-billet
Uhlalutyo lwenzuzo yezixhobo zokufudumeza zebillet eziqhubekayo:
Usebenzisa inkqubo yokuqengqeleka ngokuthe ngqo (thatha isiphumo sonyaka seetoni ezisisigidi esi-1 njengomzekelo), iinzuzo ezahlukeneyo eziveliswayo:
1. Ukusetyenziswa kwamandla kunye nokunciphisa ukukhutshwa kwesithando sokufudumala
Kwiibhilidi eziqhelekileyo kunye neentambo zocingo, ukusetyenziswa kwamandla ngetoni nganye yemveliso yensimbi malunga ne-650kWh, malunga ne-520kWh isetyenziselwa ukutshisa i-billet ukuya kwi-1150 ° C, ngelixa ukusetyenziswa kwamandla kwi-rolling yi-110kWh kuphela. Nangona kunjalo, obona bushushu bomzimba ngetoni nganye yebillet kobu bushushu bungama-230kWh kuphela, kwaye ilahleko ezahlukeneyo zobushushu ezifana nokusebenza kakuhle kobushushu beziko lokufudumeza kudlula i-50%. Ngoko ke, ukuqengqeleka ngokuthe ngqo ngaphandle kokufudumeza kunokugcina amafutha kunye nokunciphisa ukusetyenziswa kwamandla.
Ukuphoswa ngokuqhubekayo izixhobo zokufudumeza i-billet ezisebenzisa amalahle njengamafutha, nakwimeko yokuhanjiswa kwe-billet ngokuqhubekayo, umyinge wokusetyenziswa kwamalahle eziko lokufudumeza yi-45kg / t yentsimbi. Ukupheliswa kwenkqubo yeziko lokufudumeza kunokonga malunga neetoni ezingama-45,000 zamalahle asemgangathweni nyaka ngamnye, nto leyo eguqulela ekuncitshisweni kweetoni ezili-117,000 zokukhutshwa kwekharbon, iitoni ezingama-382.5 zesulfure dioxide, kunye neetoni ezingama-333 zenitrogen oxides.
Ixabiso leyunithi yamalahle yi-1,000 yuan / t, kwaye ukupheliswa kokufudumeza kunye nokusetyenziswa kwe-rolling ngokuthe ngqo kunokugcina i-yuan engama-45 ngetoni yensimbi, enokugcina i-yuan yezigidi ezingama-45 ngonyaka.
Isithando somlilo sisebenzisa i-blast furnace gas njenge-fuel, nakwimeko yokuhanjiswa kwe-billet ngokuqhubekayo, i-avareji yokusetyenziswa kwegesi yesithando somlilo yi-250m3 / t yensimbi. Inkqubo yesithando somlilo iyacinywa kwaye igesi yomlilo isetyenziselwa ukuvelisa amandla. Ngokutsho kwegesi ye-3.5m3 yokuqhuma kwesithando somlilo, i-1 kilowatt-yure yombane inokuveliswa, kunye netoni yensimbi inokuguqulwa ibe yi-71.4kwh. Ngokobalo lwenzuzo yokuvelisa amandla e-0.5 yuan/kwh emva kokuba kutsalwe ukuzisebenzisela kunye nokusetyenziswa, inzuzo yonyaka yokuvelisa amandla okongeziweyo yi-35.71 yezigidi zeeyuan.
2. Ukunciphisa ilahleko yokutshisa i-oxidation
Ukusetyenziswa kwe-rolling ngokuthe ngqo kuthintela ukufudumeza kwesibini kwe-billet kwaye kunokunciphisa ilahleko yokutshisa i-oxidation ubuncinane nge-0.6%. Ixabiso leyunithi yi-2,000 yuan / t, enokugcina i-12 yezigidi zeeyuan ngonyaka.
3. Ukuqhubela phambili ukuphosa ukusika umlilo kunye nokunciphisa umthungo
Ukuqengqeleka ngokuthe ngqo kwamkelwa, kwaye i-billet eqhubekayo yokuphosa iyatshintshwa ukusuka kwi-torch cutter ukuya kwi-shear ye-hydraulic. Iindleko zokusetyenziswa kwegesi ye-torch cutter malunga ne-0.5 yuan / t, kwaye yonke i-12m ye-billet slit yi-5mm, ukusetyenziswa kwensimbi elinganayo yi-0.47kg / t. Ngokwezibalo ze-1 yezigidi zeetoni, ilingana ne-1.44 yezigidi ze-yuan ekunciphiseni ngonyaka i-slitting kunye neendleko zegesi zokusika umlilo.
4. Ukugcinwa kweziko lokufudumeza kunye nokunciphisa abasebenzi
Imveliso yonyaka ye-1 yesigidi seetoni ze-push-steel zokufudumeza ilingana ne-avareji yeendleko zonyaka zokugcinwa kwe-750,000 yuan, abasebenzi baxabisa i-yuan yesigidi esi-1, kwaye ukusetyenziswa kwamandla ngoomatshini bokufudumeza kubiza i-1.5 yezigidi. Emva kokucinywa ngokupheleleyo kwesithando somlilo, ukugcinwa kunye neendleko zabasebenzi zingancitshiswa nge-3.25 yezigidi.
Ukushwankathela izibonelelo eziqhubekayo zokuphosa izixhobo zokuqengqeleka ze-billet, zokwenza intsimbi eqhelekileyo kunye nomgca wemveliso oqengqelekayo kunye nemveliso yonyaka yeetoni ezi-1 zezigidi kusetyenziswa igesi yomlilo yoqhushumbo njengamafutha kunye nokutshaja okushushu kunye nokuhanjiswa okushushu kweebhilidi zokuphosa eziqhubekayo, emva kokufudumeza. isithando somlilo siphelisiwe, inkqubo eqhubekayo yokuphosa kunye ne-rolling ingasetyenziswa. Izisa inzuzo yonyaka ye-52.4 yezigidi zeeyuan, kwaye ngokwedatha yokusebenza, ukusetyenziswa kombane kwesixhobo esitsha sokuphosa kunye nokuqengqeleka kuphantse kulingana naleyo yebhedi yokuqala yokupholisa, itafile yerola yokutya eshushu, kunye necrane ehambayo. Ukushisa okuphantsi kwe-billet echanekileyo kuya kwandisa ukusetyenziswa kwamandla okuguqa malunga nentsimbi ye-10kwh / t, okubangelwa ukusetyenziswa kwamandla onyaka okongeziweyo malunga nezigidi ezi-6. Emva kokuxhuzulwa, inzuzo yezoqoqosho iyonke iseyi-46.4 yezigidi zeeyuan, nto leyo enomtsalane kakhulu.
