根据下列原料成分性质,计算烧结矿成分: 求烧结矿的TFe%?
正确答案:
①精矿带入烧结矿中铁的含量:
70×(1-8%)×68%=43.792
精矿烧成量=64.4
②石灰石烧成量:
14×(1-2%)×(1-45%)=7.546
③白云石烧成量:
2×(1-4%)×(1-45%)=1.056
④生石灰烧成量:
3×(1-20%)=2.4
⑤焦粉的烧成量:
5×(1-7%)×(1-80%)=0.930
⑥高炉灰的烧成量:
6×(1-7%)×(1-10%)=5.022
高炉灰带入烧结矿中含铁量
6×(1-7%)×45%=2.511
带入烧结矿中总铁量
43.792+2.511=46.303
总的烧成量:
64.4+7.546+1.056+2.4+0.93+5.022
=81.354
烧结矿TFe%=(46.303/81.354)*100%=56.92%
烧结矿TFe%为56.92%。
70×(1-8%)×68%=43.792
精矿烧成量=64.4
②石灰石烧成量:
14×(1-2%)×(1-45%)=7.546
③白云石烧成量:
2×(1-4%)×(1-45%)=1.056
④生石灰烧成量:
3×(1-20%)=2.4
⑤焦粉的烧成量:
5×(1-7%)×(1-80%)=0.930
⑥高炉灰的烧成量:
6×(1-7%)×(1-10%)=5.022
高炉灰带入烧结矿中含铁量
6×(1-7%)×45%=2.511
带入烧结矿中总铁量
43.792+2.511=46.303
总的烧成量:
64.4+7.546+1.056+2.4+0.93+5.022
=81.354
烧结矿TFe%=(46.303/81.354)*100%=56.92%
烧结矿TFe%为56.92%。
