摘要
针对从德国引进的５０ｔＵＨＰ（ＥＢＴ）电炉－ＬＦ精炼生产线在试生产中存在的工艺参数不稳定、生产效率低、消耗高及钢品种开发少等问题，莱钢特钢厂从优化生产工艺参数和稳定操作入手，通过设计合理的精炼渣系，使脱硫率提高了３０％以上，轴承钢中钢的含氧量降低到２．０×１０－３％以下，成本降低了３５．５２元／ｔ钢。
t UHP(EBT) electric arc
furnace-LF refining production line of special steel plant of Laiwu iron and steel general works
is introduced from Germany,the main questions of this production line are unstable process
parameter,low productivity,high consumption and weak development of kinds of
steel,etc,Through optimizing process parameter and stabilizing operation of production system,
reasonable design refining slag system,the desulphurization ratio is increased by a factor of
30% above,the oxygen content in bearing steel is decreased to below 210-3% and the
production cost is decreased by 3552 yuan/t,steel
