摘要： A sliding nozzle apparatus for a molten metal holding vessel including a fixed nozzle member and a fixed plate therefor which are supported by an upper or fixed bracket secured to the vessel, and a movable nozzle member and a slidable plate therefor which are supported by a lower or movable bracket having one edge hinged to the upper bracket, while its opposite edge remote from its hinged connection to the upper bracket is removably connectable to the upper bracket to bring the slidable plate into contact with the fixed plate. A first set of coil springs are located adjacent to the edge of the lower bracket at which it is hinged to the upper bracket, and a second set of coil springs are located adjacent to the opposite edge of the lower bracket. The first set of coil springs are deflected to a greater degree than the second set of coil springs, or are, in other words, preloaded differently from the second set of springs.

摘要： A casting nozzle joint structure capable of easily positioning and jointing a nozzle without any holder for fixing and supporting a continuous casting nozzle therethrough. The joint structure comprises fitting mechanism formed in and on the mating faces of the continuous casting nozzle and the pressure clamper. The fitting mechanism includes a convex portion and a concave portion formed in and on the mating faces of the continuous casting nozzle and the pressure clamper so that they fit one another. The concave or convex portion formed in the mating face of the continuous casting nozzle is fitted on or in the convex or concave portion formed in the mating face of the pressure clamper, and this pressure clamper clamps the fitted engagement. Thus, the nozzles can have their outlet bores positioned, and the submerged entry shroud can have its discharge port oriented.

摘要翻译： 一种铸造喷嘴接头结构，其能够容易地定位和接合喷嘴，而没有任何用于固定和支撑连续铸造喷嘴的保持器。 接头结构包括形成在连续铸造喷嘴和压力夹持器的配合面中及其上的配合机构。 配合机构包括形成在连续铸造喷嘴和压力夹持器的配合面中及其上的凸部和凹部，使得它们彼此适配。 形成在连续铸造喷嘴的配合面中的凹部或凸部配合在形成于压力夹持件的配合面的凸部或凹部中，该压力夹持器夹持配合接合。 因此，喷嘴可以具有它们的出口孔定位，并且浸没的进入护罩可以使排出口定向。
