    • An applicator spreads a treatment agent, such as flux powder or granules, uniformly on the surface of molten metal during continuous casting. The flux is supplied to the applicator and argon or other gas under pressure is also supplied adjacent the applicator in at least two directions. A programmable controller controls the gas feed in each of the directions so that each gas flow is independently controllable. The applicator preferably is a frusto-triangular-shaped pan having a narrow end and a wider end with the narrow end connected to the supply of flux. The applicator is supported by a base having an upper surface with a series of channels defined by vanes so that the flux is divided along the channels and then exits at the wider end of the applicator. The base is either flat or domed.
    • 连续铸造期间,涂布器将熔剂粉末或颗粒剂等处理剂均匀地铺展在熔融金属表面上。 助熔剂被供应到施加器,并且在至少两个方向上也在施加器附近供应氩气或其它压力气体。 可编程控制器在每个方向上控制气体进料,使得每个气体流量是独立可控的。 施加器优选地是截头圆锥形的盘,其具有窄端和较宽端,窄端连接到焊剂的供应。 施加器由具有上表面的基座支撑,该上表面具有由叶片限定的一系列通道,使得通量沿通道分开,然后在施加器的较宽端处离开。 基地是平坦的或圆顶的。

    • A molten metal slide gate valve for use on a ladle or tundish. The slide gate valve uses a refractory plate or plates having a shallow groove all around the periphery of one or both surfaces of the plate. The groove surrounds the molten metal orifice in the plate. The base of the groove has a porous refractory insert connected to a source of nonoxidizing gas under pressure to provide a nonoxidizing gas seal all around the molten metal orifices in the slide gate valve and to prevent the aspiration of air into the molten metal orifices during discharge of the molten metal from the ladle or tundish.
    • 一种用于钢包或中间包的熔融金属滑动闸阀。 滑动闸门使用在板的一个或两个表面的周边周围具有浅槽的耐火板或板。 槽围绕板中的熔融金属孔。 槽的底部具有与压力下的非氧化气体源连接的多孔耐火材料插入件,以在滑动闸阀中的熔融金属孔周围提供非氧化气体密封,并且防止在排放期间将空气吸入熔融金属孔中 的来自钢包或中间包的熔融金属。
