If it were shut down abnormally , the direct economic loss will be at least 300 thousand yuan rmb per hour . even if it switched on immediately after shutoff , the oxygen and nitrogen production can return to normal at least four hours later , and it has to spend seventy - two hours to make liquid oxygen and its purity meet the requirements , in which the losses from half a steelmaking and ironmaking production loads or so are not included 如果非正常停車一次每小時(shí)至少直接經(jīng)濟(jì)損失30萬(wàn)元,即使停車后馬上啟動(dòng),也至少要4個(gè)小時(shí)以后氧氮產(chǎn)量才可能恢復(fù)正常,液氬產(chǎn)量和純度要達(dá)到要求則需要72個(gè)小時(shí),這還不包括煉鋼和煉鐵要減一半左右生產(chǎn)負(fù)荷的損失。
