    摘要： The weight and distribution of a coating applied to a moving substrate are controlled by directing a gaseous fluid through a nozzle opening to the substrate while the coating is in a liquid state. The gaseous fluid impinges onto the substrate and removes excess coating material and generally smooths out the liquid coating. The nozzle opening tapers uniformly from its ends to about its midpoint causing the gaseous fluid passing therethrough to establish a coating profile which is substantially uniform or which is slightly heavier along the central portion of the substrate than along the edges. In accomplishing coating control, the rate of taper on the profile of the nozzle opening is adjusted in response to changes in coating operation variables which affect coating weight and distribution. The apparatus of the invention allows for rapid changes to be made in the profile of the nozzle opening.

    摘要翻译： 施加到移动的基底上的涂层的重量和分布通过将气体流体通过喷嘴开口引导到基底而被控制，同时涂层处于液体状态。 气态流体冲击到基板上，并去除多余的涂层材料，并且通常使液体涂层平滑。 喷嘴开口从其端部均匀地逐渐变细到其中点，导致通过其中的气体流体形成基本上均匀的涂层轮廓，或者沿着衬底的中心部分比沿着边缘略微重的涂层轮廓。 在完成涂层控制时，响应于影响涂层重量和分布的涂布操作变量的变化，调节喷嘴孔的轮廓上的锥度比率。 本发明的装置允许在喷嘴开口的轮廓中进行快速变化。

    摘要： H2S emissions during slag quenching are significantly minimized by a process involving the pouring of slag into holding pits in incremental layers and time intervals which lead to given slag thermal arrest temperatures. The incrementally poured slag may be air cooled for a 2 to 4 day period or quenched with oxidant containing water to further minimize H2S emissions.

    摘要： Significant shape control is attained during strip rolling without significant gage variation by selection of an operating point or range in which considerable variations in roll force can be made without producing significant gage variation. The operating point is selected with regard to final strip gage and roll diameter.

    摘要： An internally liquid cooled rotatable drum open to the atmosphere for continuously solidifying molten metal on its outer surface is provided with a coaxially rotating spider carrying rollers in radial slots which under the action of centrifugal force roll on the drum inner surface. The spider is rotated at a speed sufficient to throw a rotating layer of cooling liquid against the inside surface of the drum by centrifugal force, and the action of the rollers on the surface being cooled breaks up incipient film boiling.
