一体式浇注泥套在包钢7^(#)、8^(#)高炉上的应用

Application of Funnel-shaped Fossula Rotunda for Monoblock Casting in 7^(#)and 8^(#)Blast Furnaces of Baotou Steel

文章利用三维造型软件对适用于大型高炉的铁口泥套进行设计,总结出一体式浇注铁口泥套的制作方法,介绍了该方法的技术特点及在包钢7^(#)、8^(#)高炉的应用情况。试验表明:一体式浇注泥套的使用寿命大幅提高,降低了炉前工人的劳动强度,有利于高炉稳定顺行。

In this paper,the three dimension(3 D)modeling software is used to design the funnel-shaped fossula rotunda at iron notch suitable for large blast furnace,the manufacture method of funnel-shaped fossula rotunda at iron notch for monoblock casting is summarized as well as its technical characteristics and application in 7^(#)and 8^(#)blast furnaces of Baotou Steel are introduced.The experiment results showed that the service life of funnel-shaped fossula rotunda for monoblock casting was greatly improved and labor intensity of furnacemen was reduced,which were to the benefit of stable and trouble-free operation of blast furnace.
