Beschreibung
Zusammenfassung:	The invention discloses a method for heating a CAS-OB refining furnace, which is characterized in that the content of oxygen supplied to CAS-OB molten steel is controlled to be below 50ppm, the slag amount of a converter in a steel ladle is controlled to be below 10kg/t, and a leaching cover is lowered to be 100-200mm below the slag surface in the heating process of the CAS-OB refining furnace. The invention relates to a method for heating a CAS-OB refining furnace, which is characterized in that the content of oxygen supplied to CAS-OB molten steel is controlled to be below 50ppm, the slag amount of a converter in a steel ladle is controlled to be below 10kg/t, and a leaching cover is lowered to be 100-200mm below the slag surface in the heating process of the CAS-OB refining furnace. 本发明公开了一种CAS-OB精炼炉升温的方法，其供CAS-OB钢水的氧含量控制在50ppm以下，钢包中转炉下渣量控制在10kg/t以下，CAS-OB精炼炉升温过程将降浸罩降低至渣面下100-200mm。本发明一种CAS-OB精炼炉升温的方法，其特征在于，其供CAS-OB钢水的氧含量控制在50ppm以下，钢包中转炉下渣量控制在10kg/t以下，CAS-OB精炼炉升温过程将降浸罩降低至渣面下100-200mm。
