Ukuhlaziywa kwenzuzo kwemishini yokushisa ye-billet eqhubekayo:

Ngokusebenzisa inqubo yokugoqa okuqondile (thatha isilinganiso saminyaka yonke samathani ayizigidi ezingu-1 njengesibonelo), izinzuzo ezihlukahlukene ezikhiqizwayo:

1. Ukusetshenziswa kwamandla kanye nokunciphisa ukukhishwa kwesithando somlilo

Ezigayweni ezijwayelekile ze-billet nezintambo zokugaya, ukusetshenziswa kwamandla ngethani ngalinye lokukhiqiza insimbi cishe ku-650kWh, cishe u-520kWh esetshenziselwa ukushisa i-billet ku-1150 ° C, kuyilapho ukusetshenziswa kwamandla okuginqika kungu-110kWh kuphela. Kodwa-ke, ukushisa kwangempela ngokomzimba ngethani ngalinye le-billet kulokhu kushisa kungu-230kWh kuphela, futhi ukulahlekelwa ukushisa okuhlukahlukene okufana nokusebenza kahle kokushisa kwesithando sokushisa kudlula ama-50%. Ngakho-ke, ukugoqa okuqondile ngaphandle kokushisisa kungasindisa uphethiloli futhi kunciphise ukusetshenziswa kwamandla.

Okokusebenza okuqhubekayo kokushisisa kwe-billet esebenzisa amalahle njengophethiloli, ngisho nasendabeni yokulethwa okuqhubekayo kokusakazwa kwe-billet hot, ukusetshenziswa kwamalahle okumaphakathi kwesithando somlilo kuyinsimbi engu-45kg/t. Ukuqedwa kwenqubo yokushisa isithando somlilo kungonga amathani angaba ngu-45,000 117,000 amalahle avamile unyaka ngamunye, okuhunyushwa ekuncishisweni kwamathani angu-382.5 333 okukhishwa kwekhabhoni, amathani angu-XNUMX e-sulphur dioxide, namathani angu-XNUMX e-nitrogen oxides.

Iyunithi yentengo yamalahle ingu-1,000 yuan/t, futhi ukuqedwa kokushisisa nokusebenzisa ukugingqika okuqondile kungonga ama-yuan angama-45 ngethani lensimbi, elingonga ama-yuan ayizigidi ezingama-45 ngonyaka.

Ukuze isithando somlilo sishisise sisebenzisa i-blast furnace gas njengophethiloli, ngisho noma kwenzeka ukukhishwa okuqhubekayo kokulethwa kwe-billet hot, ukusetshenziswa kwegesi okumaphakathi kwesithando somlilo kuyinsimbi engu-250m3/t. Inqubo yokushisa isithando somlilo ikhanseliwe futhi igesi ye-blast furnace isetshenziselwa ukukhiqiza amandla. Ngokwegesi ye-3.5m3 blast furnace, i-kilowatt-hora likagesi lingaphehlwa, futhi ithani lensimbi lingashintshwa libe ngu-1kwh. Ngokwezibalo zenzuzo yokuphehla amandla engu-71.4 yuan/kwh ngemva kokudonswa kokuzithengela nokusetshenziswa, inzuzo yonyaka yokukhiqiza amandla engeziwe yi-yuan eyizigidi ezingu-0.5.

2. Ukuncipha kokushiswa kwe-oxidation

Ukusetshenziswa kokugoqa okuqondile kugwema ukushisa kwesibili kwe-billet futhi kunganciphisa ukulahlekelwa kokushiswa kwe-oxidation okungenani ngo-0.6%. Intengo yeyunithi ingu-2,000 yuan/t, engonga amayuan ayizigidi eziyi-12 ngonyaka.

3. Ukusika umlilo okuqhubekayo nokusika ukuncishiswa komthungo

Ukugoqa okuqondile kuyamukelwa, futhi i-billet yokuphonsa eqhubekayo iyashintshwa isuka kusisiki sethoshi iye kushear ye-hydraulic. Izindleko zokusetshenziswa kwegesi komsiki wethoshi zingaba ngu-0.5 yuan/t, futhi yonke i-12m billet slit ingu-5mm, ukusetshenziswa kwensimbi okulingana ngu-0.47kg/t. Ngokwezibalo zamathani ayizigidi ezingu-1, ilingana ne-1.44 million yuan ekunciphiseni ngonyaka izindleko zegesi yokusika nokusika umlilo.

4. Ukugcinwa kwesithando sokushisa nokunciphisa abasebenzi

Ukukhishwa kwaminyaka yonke kwamathani ayizigidi ezingu-1 wesithando somlilo esishisayo kulingana nesilinganiso sezindleko zonyaka zokulungisa ama-yuan angu-750,000, ukusebenza kubiza i-yuan eyisigidi, kanti ukushisisa iziko kubiza izigidi ezingu-1. Ngemuva kokukhanselwa okuphelele kwesithando sokushisa, izindleko zesondlo nezokusebenza zingancishiswa ngezigidi ezingu-1.5.

Ukufingqa izinzuzo zemishini yokugoqa ye-billet eqhubekayo, yolayini ojwayelekile wokwenza insimbi kanye nokukhiqiza amathani ayizigidi ezingu-1 ngonyaka kusetshenziswa igesi yesithando somlilo njengophethiloli nokushaja okushisayo kanye nokulethwa okushisayo kwamabhilidi asakazayo, ngemva kokushisisa. isithando somlilo siqedwa, inqubo eqhubekayo yokusakazwa nokugingqa ingasetshenziswa. Iletha inzuzo yonyaka yama-yuan ayizigidi ezingu-52.4, futhi ngokusho kwedatha yokusebenza, ukusetshenziswa kukagesi kwempahla eqhubekayo yokusakazwa nokugingqika esanda kungezwa kucishe kulingane nalokho kombhede wokuqala wokupholisa, ithebula le-hot feed roller, kanye ne-crane yokuhamba. Izinga lokushisa eliphansi le-billet eligoqiwe lizokwandisa ukusetshenziswa kwamandla okugoqa ngensimbi engaba ngu-10kwh/t, okuholela ekusetshenzisweni kwamandla okungeziwe ngonyaka okungaba izigidi eziyisi-6. Ngemuva kokudonswa kwemali, inzuzo yomnotho iyonke isengama-yuan ayizigidi ezingama-46.4, okuyinto emangalisa kakhulu.
