全年可少用铁水一千六百三十二吨,价值二十五万三千元。涟源钢铁厂顶吹转炉生产,原来三班操作不一,长期存在化渣不良、渣料多、喷溅严重、吹损大、供氧时间长等问题。最近,他们对装入、造渣、供氧等三项顶吹转炉炼钢关键制度进行分析,认为喷枪位置不当是化渣不良、大量喷溅的主要因素,因而决定用0.618法在6000—1200毫米(指喷枪端距平静金属液面高度)范围内进行优选。
A total of 1,632 tons of hot metal will be available for less than two hundred and fifty-three thousand yuan a year. Lianyuan Iron and Steel Plant top-blown converter production, the original three different operations, the existence of long-term bad slag, slag and more splashes, blowing large, long oxygen supply and other issues. Recently, they analyzed the key systems of the three top-blown converter steelmaking such as loading, slagging and oxygen supply, and concluded that the improper position of the spray gun is the main factor of bad slag and splashing. Therefore, they decided to use 0.618 method at 6000-1200 Mm (referring to the gun end of the level of calm metal liquid level) is preferred.
