Dear Hamid , I would like to estimate the power requirement , Please suggest : The available data from vender is : – consumption of hot metal : 0.75 – Consumption of DRI : 0.705 – Steel Scrap : 0.045 – Tapping weight (proposed) : 112.8 T per heat – Average electrical power reqd. : 47.6 MW (say 50 MW) (@ 280 KWH/T) – Power on time: : 27 Min. – Blowing time : 31 Min. – Tap to Tap time : 40 Min. (Considering both the vessels) – Nos. of Heats : 36 per day – Productivity based on 320 days/yr. (320 days x 36 heats x 112.8 T/heat) : Approx. 1.3 MTPY On this given information I calculate the power as below : – Tapping weight (proposed) : 112.8 T per heat Energy units required per T : @280 KWH/T Total Energy units required for 1 Heat : 112.8 x 280 = 31584 KWH Power on time: : 27 Min. = 0.45 H – In order produce 112.8 T in 27 min Amount of power required : 31584 /0.45 = Approx 70 MW Please recheck and confirm the conflic in power estimation i.e 70 MW instead of 50 MW ….. Thnx & Regards ASAD
