Abstract
一种隔板构件,用它在转包中构成一个包室,以便用镁来处理铸铁熔料。转包的隔板构件的大小和形状对在转包中处理铸铁熔料的效率,以及对获得剩余镁含量的精度均有决定性的影响。为了对这个影响进行最佳控制,隔板构件的长度L按照公式L=600×T0.45×A来确定,而其高度H则按公式H=0.5L×A来确定,式中A是一个系数,它的数值介于0.5至1.5之间,其具体数值取决于硫的重量含量在0.01%至0.15%间的取值,它还取决于转包包身中的耐火材料衬料的厚度在40至150毫米之间的取值情况。
Description
本发明涉及一种隔板结构,可用它在转包中构成一个包室,以便用镁对铸铁熔料进行处理。
用镁处理铸铁熔料的转包,在转包的底部有一个包室,该包室借助于包室壁与熔料隔开。该包室壁在相对转包底部不同高度的地方开一定数量的孔。在转包从它的水平装料位置旋转到它的垂直处理位置期间及其以后,铸铁熔料穿过最底部的开孔进入该包室,并以某一被控制的方式汽化镁。镁蒸汽通过上面各个开孔从包室中逸出进入铸铁熔料中。必须把一定数量的镁加到含有某一硫含量的大量铸铁中,因此例如最初的0.1%硫含量被减少到0.006%,并且在铸铁熔料中能获得例如是0.045%的剩余镁含量。
按前面提到的理由,围成包室的隔板相对于被处理的铸铁熔料数量必须有一定的形状和大小。如果包室的体积选的过大和过小,则处理效率将降低,而且在铸铁熔料中获得预定剩余镁含量的精度也要受损害。
因此,本发明的主要目的是提供一种隔板,该隔板可供相对于被处理铸铁熔料的数量具有某一形状和大小的转包包室使用,它能保证以高效率用镁处理铸铁熔料,并能以高精度在铸铁熔料中获得预定的剩余镁含量。
根据本发明,一个用于使用镁处理铸铁熔料的隔板构件(或称转包室)具有弓形和直角形形状,并带有一定数量的开孔。这些开孔位于距转包包底不同高度的位置上。以毫米为单位的隔板长度L相*于以吨做单位的铸铁熔料的数量T的关系按公式L=600×T0.45×A来确定,而以毫米为单位的隔板高度H则按公式H=0.5L×A来确定,公式中A是一个系数,它的值处在0.5~1.5之间,具体值取决于处在0.01~0.15%之间的硫的含量,并取决于处在40~150毫米间的转包包身的耐火材料炉衬的厚度。
表征本发明的新颖性的各种特点是通过权利要求中的特征指出来的,这些权利要求附加在本发明中并构成本发明公开的一部分。为了对本发明及由它的使用所获得的各个操作优点及特定目的更好地理解,应该参照附图和描述的事情,后者用图和发明的最佳实施例叙述。
在附图中:
图1表示截面视图,它表示出在转包底部区域有一个包室,隔板具有弓形形状;
图2是对图1沿A-A线剖开的示意截面图;
图3是转包底部的示意截面视图,它具有隔板为直角形的包室;
图4是沿B-B线把图3剖开的示意截面视图。
正如附图所示,包室2位于包身1内。镁4通过开孔5a被置于包室2中,开孔5a可用一个关闭物5对其封闭。包室2的隔板2a具有开孔3、3a和3b,这些开孔具有不同的功能。开孔3用来使金属熔料6流进包室2内,而镁的蒸汽4通过开孔3a和3b离开包室2。包身1以已知的方式从附图中未示出的水平位置旋转到如图1和3所示的垂直处理位置,从而使镁在铸铁熔料6穿过开孔3进入包室2的瞬间开始汽化。
以毫米为单位计量的隔板2a的长度L是按照公式L=600×T0.45×A相对于以吨为单位计量的将被处理的铸铁熔料6的数量T来决定的。而以毫米为单位计量的隔板2a的高度H是按照公式H=0.5L×A确定的。系数A的值处在0.5至1.5之间,其具体值取决于在0.01%至0.15%之间的硫含量的取值。也取决于包身1的耐火材料炉衬的厚度S在40毫米到150毫米之间的取值。
在隔板2a上的开孔3,3a和3b的以厘米2为单位计量的总横截面积F按照公式F=7.3×T0.3×B来确定,式中T仍旧是以吨为单位计量的要被处理的铸铁熔料6的数量。系数B视硫成分的含量在0.01%至0.15%间的变化而在0.6到1.4间变化。
开孔3,3a和3b总的横截面积被有利地加以分配,以便使一个和多个较低的开孔构成横截面积的25~45%,并使一个和几个上面的开孔3a构成横截面积的15~35%,还使一个或几个中间的开孔3b构成横截面积的35~55%。
隔板2a可以取如图1所示弓形形状,或取如图3所示的直角形状。包身1可以取如图1所示的圆形形状或取图3所示的直角形状。
虽然为了说明本发明各个原理的应用,本发明的各个特定实施例已被示出和详细叙述,但人们应该理解;在不偏离这些原理的前提下也可以用另外方式具体实施。
