摘要

70 t电弧炉的炉料装入量为80～81 t

其中热直接还原铁热压块HBI为14.6～15.2 t

铁水23～27 t

其出钢量77～78 t

电耗316～324 kWh/t

氧耗29.7～33.0 m~3/t

冶炼周期48～54 min。生产实践表明

热压块是优质废钢的替代品

可促进电弧炉脱磷和脱碳反应

降低氧耗1.3～3.2 m

但每增加1%热压块则增加电耗3.5kWh/t

所以炉料为全废钢时不宜配加热压块

当加入30%铁水和加入10%热压块时可以达到冶炼过程最优化。

Abstract

Charged weight for the 70 t arc furnace is 80-81 t including direct reduction iron hot briquette (HBI) 14.6-15.2 t and hot metal 23-27 t

its tapping liquid amount is 77-78 t

electric power consumption 316 ~ 324 kWh/t

oxygen consumption 29.7-33. 0 m3/t and tap-to-tap time 48 ~54 min. Steelmaking practice shows that HBI is a substitute for quality scrap

it is available to improve dephosphorization and de-carbon reaction

decrease oxygen consumption 1.3-3.2 m

but with increasing every 1% charge of HBI the electric power consumption increases 3. 5 kWh/t

therefore it is not suitable charging HBI only with scrap

as charging 30% hot metal and 10% HBI the steelmaking process is optimization.
