瑞典Motala Verkstad厂已装设了一台现代化的直接铸钢装置,并已成功地进行了生产。本文叙述它的一些主要特点。钢液注入底部有一个注口的中间包内。中间包注口与结晶器在同一中心线上。注口大小根据所要求的浇注速度与铸坯断面来选择。若用底注盛钢桶,一般要安装人工操作的塞棒系统。在这种情况下,盛钢桶的衬砖一般要比普通操作时用的衬砖具有更好的绝热性能。在Motala厂,却用普通的衬砖,但盛钢桶比平常更充分地被预热。在盛钢桶与结晶器之间加一个耐火材料砌成的中间包,这是为了在达到所要求的最大流速时能获得纯 A modern direct cast steel unit has been installed at the Motala Verkstad plant in Sweden and production has been successfully carried out. This article describes some of its main features. The molten steel is poured into the tundish with a nozzle at the bottom. The tundish nozzle and mold are on the same centerline. The size of the sprue is chosen according to the desired casting speed and slab section. If the bottom note ladle, the general installation of manually operated stopper system. In this case, the ladle lining bricks generally have better thermal insulation properties than the lining bricks used in ordinary operations. At Motala, ordinary lining bricks were used, but ladle was preheated more fully than usual. Add a refractory tundish between the ladle and the crystallizer in order to get pure when reaching the required maximum flow rate
