新的薄板坯连铸机的最大特点,结晶器宽面板的几何形状是一种完全新式的设计。其目的在固定式结晶器的宽面板之间形成一个垂直方向带锥度的漏斗区(漏斗开孔处的宽度为170 mm,相当于普通板坯结晶器的宽度),以便提供足够的空间,能使用适当的异形浸入式水口。而中间漏斗区的两个侧壁仍然是平行的,其间的距离相当于板坯的厚度。在结晶器上部漏斗区形成的坯壳通过结晶器时被改型成薄板坯的尺寸。第一台试验设备已于1985年10月11日在该公司的布什铸钢厂第一次试浇成功,顺利地浇完了5 t
The greatest feature of the new thin slab caster, the wide geometry of the mold is a completely new design. The purpose of this is to create a vertically tapered funnel zone (the width of the funnel opening is 170 mm, corresponding to the width of a conventional slab mold) between the wide panels of the stationary crystallizer in order to provide sufficient space for Use a suitable shaped immersion nozzle. While the two side walls of the intermediate funnel zone are still parallel, with a distance corresponding to the thickness of the slab. The shell formed at the upper hopper zone of the crystallizer is modified to the size of the slab as it passes through the crystallizer. The first test equipment was successfully poured on the first test at the company’s bush steel plant on October 11, 1985, and poured successfully for 5 t
