荷兰Hoogovens厂的复合吹炼转炉,底部装有一种标准透气砖进行底吹,顶部则采用一种双流氧枪。据称,在离一般氧枪头部一定距离处,装上一个环形的铜片,就可以改成双流氧枪。采用双流氧枪可以提高废钢比和金属收得率,二次氧喷咀的寿命达250炉。 Hoogovens厂转炉冶炼用铁水的成份（％）是:C 4.3—4.5,Mn 0.7,Si 0.6,Ti 0.08,S 0.022,P 0.01,铁水温度为1350℃。 100t复合吹炼转炉的冶炼情况是:一次氧流量为300m~3/min,二次氧流量为50
Hoogovens plant in the Netherlands compound blowing converter, the bottom with a standard blower for bottom blowing, the top is the use of a double-flow oxygen gun. Allegedly, at a distance from the general lance head at a distance, fitted with a ring of copper, you can change to double-flow lance. The use of double-flow oxygen lance can improve scrap ratio and metal recovery rate, secondary oxygen nozzle life of 250 furnaces. The composition (%) of the hot metal for converter smelting in Hoogovens plant is: C 4.3-4.5, Mn 0.7, Si 0.6, Ti 0.08, S 0.022, P 0.01, and the hot metal temperature is 1350 ° C. 100t compound blowing converter smelting situation is: an oxygen flow of 300m ~ 3 / min, secondary oxygen flow of 50
