Abstract

连铸钢带的结晶器，它具有被冷却的宽侧壁和窄侧壁，宽侧壁构成漏斗形的浇口区，浇口区向窄侧壁方向及沿浇注方向减小到要浇铸的带材的尺寸。为了使连铸结晶器中紧靠金属液面下方铸坯的应力较小，浇口区(9)的宽侧壁(1，2)由基本上相互平行的第一段(a，a′)的两面距离逐渐缩减到铸带厚变的另一段(b，b′)构成，第一段持续深入到在浇注期间要进行调节的金属液面(11)之下面。

Description

本发明涉及一种连铸钢带的结晶器，它具有加以冷却的宽侧壁和窄侧壁，其中宽侧壁的浇道进口区作成漏斗形，浇道进口区向窄侧壁的方向及沿浇注的方向减小到要浇铸的带材的尺寸。
由DE-PS887990已知一种这种类型的连铸结晶器，它由具有平行侧壁的下部和上部组成，上部从下部向上直到结晶器上棱边呈漏斗形展宽，为浸入熔融金属的浇注管提供了一个空间。金属液面和形成铸坯外壳的起点都位于倾斜的侧壁范围。浇道进口区的形状由浇注管的直径和浸入的深度，以及所要求的浇注管下棱边距宽侧壁的距离确定。
本发明的目的在于，提供一种上述类型的连铸结晶器，它能使连铸结晶器中紧靠金属液面下方铸坯外壳的负荷较小。
本发明达到上述目的所采取的措施为：宽侧壁的浇道进口区各由第一段和与其相连的另一段构成，两个第一段基本上相互平行，而与其相连的段落相互间的距离减小至铸模的厚度，第一段深入到在浇注期间进行调节的金属液面下方。
首先，发明人认为，浇道进口区的形状不一定必须取决于浇注管的直径和浸入深度，在金属液面上方，在一定的范围内，它是可以作成任意形状的。本发明在金属液面的范围内采用了平行的宽侧壁，使紧靠金属液面下方、还比较薄的铸坯外壳能在没有变形的条件下得到引导。
为了防止出现长裂纹的危险，第一段中的宽侧壁可以略有偏斜，为了在铸坯外壳中产生压应力，在浇注方向上相互略带有一点斜度。
宽侧壁第一段在浇注方向上的长度最好是150至350毫米。
本发明的另一特征为，平面和/或曲面的第二段与第一段圆滑地相连接。
本发明的实施例示于下述的附图中。
其中，
图1为具有展宽浇道进口区的带式浇铸结晶器之俯视图
图2为具有窄侧壁的带式浇铸结晶器之宽侧壁的内部视图
图3为沿图1Ⅱ-Ⅱ线的断面图
在图示的连铸结晶器中，两个相对着的宽侧壁1、2和两个位于宽侧壁1、2的平行部分之间的窄侧壁3、4构成了造型空间。为了冷却，宽侧壁1、2设有通道5，而通道5设有冷却介质的输入、输出导管6、7。窄侧壁3、4同样也被冷却，他们的位置可以通过螺杆8在宽侧壁1、2之间进行调节。
宽侧壁1、2朝向其中部形成漏斗形展宽的浇道进口区9，导入钢水的浇注管10伸入浇道进口区中。每一个宽侧壁1、2的内侧具有三段不同的轮廓。第一段a，a′基本上相互平行。在这段中，从金属液面11向下开始凝固，由此使还比较薄的铸坯外壳免受弯曲负荷。
在b、b′段，连铸铸坯外壳缩小到要浇注的带材的厚度。在图2中，b段用一条倾斜的直线表示，而b′段用一条弧线表示，由此清楚地表示出了可能的成型方式，即以平面或曲面或平面及曲面相组合的成型方式。
C、C′段相互的距离等于带材的厚度。
为了避免出现台阶，给铸坯外壳造成负荷，a、a′、b、b′和C、C′段之间的过渡区作成弧形。
