摘要： An adjustable mold for direct chill casting of metals has longitudinally movable end walls which are clamped between the mold side walls during casting. Each end wall is secured to a sliding carriage which supports the end wall and allows it to be moved along the end portions of the side walls. The sliding suspender has a clamping mechanism which applies a clamping force to one or both of the side walls, the force being transversely directed through a center of the end wall. The side walls are pivotable relative to one another to allow clamping and unclamping of the end walls. Preferably, one end of each side wall is pivotable so as to transversely displace the opposite end of the side wall, with the pivoting ends of the respective side walls preferably being opposite one another across the mold.

摘要： Magnesium hydroxide is added to aqueous sprays used in the cooling of steel produced by continuous casting to reduce the corrosion of ferrous metals in contact with these sprays. The magnesium hydroxide when added to aqueous sprays used in the cooling of steel produced by continuous casting further reduces the potential for calcium fluoride scale formation by reducing the fluoride content of the system water.

摘要： A twin roll casting machine that can reduce an amount of inert gas to be fed for prevention of oxidization. The machine includes an enclosure enclosing a strip in a range from chilled rolls to pinch rolls, a first swing wall within the enclosure and having a tip end movable toward and away from a surface of the strip, a sealing roll rotatably supported by the tip end of the first swing wall, a second swing wall within the enclosure and having a tip end movable toward and away from the other surface of the strip, a sealing roll rotatably supported by the tip end of the second swing wall, sealing members between peripheral edges of the swing walls and an inner surface of the enclosure, and conduits for supplying inert gas into the enclosure. The respective swing walls are swung to bring the sealing rolls close to the strip to thereby suppress flow of the inert gas from a first space to a second space.

摘要： In direct cooling an ingot emerging from a mold, two sets 136 and 142 of liquid coolant streams are discharged onto the ingot from an annulus 62 circumposed about the lower end opening 72 of the mold. One set of streams, 136, is discharged downwardly at 22.5 degrees to the axis 12 of the mold, and the other, 142, is discharged downwardly at 45 degrees to the axis of the mold. The two sets are staggered to one another circumferentially of the mold, and because of the high angle of incidence of the 45 degree set to the axis of the mold, substantial portions of the 45 degree streams rebound from the surface of the ingot at their points 144 of impact with the ingot, and mushroom into corolla-like masses of air borne liquid coolant spray 146 lying crosswise the paths of the 22.5 degree streams, which in turn entrain the spray and impact the successive layers 138 of coolant therebelow with the spray. To aid in the entrainment, the respective streams are spaced apart from one another so closely that the respective pairs of adjacent corolla-like masses of spray actually shoot up "interaction fountains" 148 of spray directly in the paths of the 22.5 degree streams of coolant. The effect is to widen the bands 135 of turbulence in the layers 138 of coolant; and the bands may even be widened to the extent of eliminating the laminar flow regime 137 in each layer. The height 133 of the bands is also commonly raised.
摘要翻译：在直接冷却从模具出来的铸块中，液体冷却剂流的两组136和142从围绕模具的下端开口72围绕的环状空间62排出到锭上。一组流136向模具的轴线12向下排出22.5度，另一组流体142向模具的轴线45度向下排出。两组在模具的周向彼此交错，并且由于45度设定在模具的轴线上的高角度入射，45度流的大部分在其点处从铸锭的表面反弹 144与锭的冲击，以及蘑菇变成花冠状的空气传播的液体冷却剂喷雾146的质量横向于22.5度流的路径，这又导致喷雾并且随着喷雾冲击连续的冷却剂层138。为了帮助夹带，相应的物流彼此间隔开，使得相应的相邻的花冠状喷雾物质对实际上直接在22.5度冷却剂流的路径中喷射喷雾的“相互作用喷射器”148 。效果是扩大冷却剂层138中的湍流带135。并且带甚至可以扩大到消除每层中层流状态137的程度。带的高度133也是普遍提高的。
