摘要： A metallurgical ladle, and more particularly the bottom of the ladle or a ladle block in the bottom of the ladle, have an outlet through which the molten metal can drain. The ladle bottom contains an open-end channel bounded by at least one wall with a major dimension perpendicular to a line joining the center of the outlet entrance to the center of the wall. In selected configurations, opposing faces of the walls bounding the open-end channel are convex in the horizontal plane and concave in the horizontal plane, respectively.

摘要： A purge plug containing a refractory material is configured to be inserted in the bottom of a ladle for introducing purging gas through a heat of molten metal in the ladle. The purge plug houses a retention chamber for holding the lead content of lead-containing molten steel alloys that leaches into, or infiltrates into, the purge plug. The purging gas supply tube is provided with a portion that protrudes into the retention chamber, thereby preventing the lead content of lead-containing molten steel alloys from entering and blocking the purging gas supply tube.

摘要： A device for connecting a fluid circulating line to a refractory element having a wall provided with a cylindrical bore comprises a gasket intended to be located into the bore and a first supporting element compressing the gasket from the outside of the bore. A second supporting element which can be introduced into the bore sandwiches the gasket together with the first Supporting element and a rod brings the two supporting elements closer so as to compress the gasket. Also, a refractory element, notably a nozzle or pouring shroud, is provided with a cylindrical bore size to receive two supporting elements and a tightening gasket sandwiched by these supporting elements.

摘要： The present invention relates to a ladle block for use in a bottom of a molten metal ladle. The ladle block reduces the amount of contaminants, particularly slag, exiting the ladle during casting operations. The ladle block includes a floor defining an outlet and sidewalls substantially orthogonal to the floor. The floor and sidewalls define a channel having dimensions of length, width and height. Channel dimensions are determined from the Froude number, which is based at least partially on the casting flow rate.

摘要： The invention relates to a crucible for the crystallization of silicon and to the preparation and application of release coatings for crucibles used in the handling of molten materials that are solidified in the crucible and then removed as ingots, and more particularly to release coatings for crucibles used in the solidification of polycrystalline silicon. The objective of the inventor was to provide a crucible which does not require the preparation of a very thick coating at the end user facilities, which is faster and cheaper to produce and which presents a stronger coating with an improved adherence to the walls. It has now been found that these problems can be solved with a crucible for the crystallization of silicon comprising a) a base body comprising a bottom surface and side walls defining an inner volume; b) an intermediate layer comprising 50 to 100 wt. % of silica at the surface of the side walls facing the inner volume; and c) a surface layer comprising 50 to 100 wt. % of silicon nitride, up to 50 wt. % of silicon dioxide and up to 20 wt % of silicon on the top of the intermediate layer.

摘要： A refractory roll cover is described that reduces the amount of noxious dust during the production of glass sheet. The roll cover comprises a plurality of segments, including low dusting millboard segments mechanically supported by highly rigidized compressed fiber segments. The millboard segments are adapted to contact the glass sheet. The millboard is chosen so that any dust produced has little affinity for the glass sheet or is not easily fluidized by convective currents. The highly rigidized compressed fiber has a fused surface that releases little dust. The resultant roll cover substantially eliminates dusting while providing a mechanically superior roll cover.
摘要翻译：描述了一种在玻璃板生产期间减少有害灰尘的量的耐火辊盖。辊盖包括多个段，包括由高度刚性化的压缩纤维段机械地支撑的低灰尘刨花板段。铣板段适于接触玻璃板。选择该刨花板使得产生的任何粉尘对玻璃板具有很小的亲和力，或者不容易被对流电流流化。高度刚性化的压缩纤维具有很少的灰尘的融合表面。所得的辊盖基本上消除了粉尘，同时提供了机械上优越的辊盖。
