Abstract: A heat insulating casting tube is disposed between the outlet orifice of a first metallurgical vessel and a second metallurgical vessel. One end of the casting tube has a removable and substantially leaktight engagement about a casting nozzle or an adapter forming an extension of the nozzle of the first vessel. The casting tube is formed of a material sinterable under the action of the heat of the liquid metal as it flows in the tube. A ring of refractory material is disposed on the tube end engaged on and surrounding the lateral surface of the casting nozzle or adapter. The internal surface of this ring is shaped as the lateral surface of the casting nozzle or adapter and has a substantially leaktight engagement with that lateral surface. The height of the ring is such that its bottom edge is located above the zone in which the liquid metal which is poured into the tube would be liable to come into contact with the internal surface of the tube.

Abstract: A coating for protecting constructions against fire and heat, comprises 10 to 80% by weight of aluminous and/or Portland cement and 5 to 20% by weight of hydrated trisodium phosphate (Na.sub.3 PO.sub.4.12H.sub.2 O). A small but effective amount of a flux can be included, which can be calcium borate and/or fluorspar, the amount being effective to assure superficial sintering of the refractory particles at a temperature between 850.degree. and 900.degree. C. This temperature range is selected because if sintering takes place below 850.degree. C., the cracks which form in the coating are filled too soon by fusion of the inorganic particles under the action of the flux; while if sintering takes place above 900.degree. C., the coating becomes detached from the supporting surface because the binder loses all of its adhesive power. The coating can also include inorganic particles, e.g. alumina, sand, perlite and/or vermiculite, and also organic particles.

Abstract translation: 用于保护结构免受火和热的涂层包含10至80重量％的铝和/或硅酸盐水泥和5至20重量％的水合磷酸三钠（Na 3 PO 4·12H 2 O）。 可以包括小但有效量的助熔剂，其可以是硼酸钙和/或氟石，该量有效地确保耐火颗粒在850℃和900℃之间的表面烧结。该温度范围被选择 因为如果在850℃以下进行烧结，则在焊剂的作用下，通过无机粒子的熔融，填充在涂层中形成的裂纹， 而当烧结高于900℃时，由于粘合剂失去其所有粘合力，所以涂层从支撑表面脱离。 涂层还可以包括无机颗粒，例如。 氧化铝，砂，珍珠岩和/或蛭石，以及有机颗粒。

Abstract: A blanket powder for covering a molten metal bath in order to prevent oxidation and to provide heat insulation contains, in addition to the ash of cereal hulls, approximately 5 to 50% by weight of non-calcined cereal hulls. The powder can thus be transported and handled without any attendant danger of contaminating dust formation and has enhanced heat-insulating power.

Abstract: A filter for molten metal comprises a series of at least two refractory mineral material plates which define between them one or more cavities. The plates each comprise a series of holes through which the liquid metal passes and by which the liquid metal is filtered. At least one of the cavities contains a material for treating the metal, for example a material for inoculating the liquid metal. The filter is used among other things to filter and treat molten metals simultaneously and to improve the quality of the metal.

Abstract: The lining for a metallurgical container comprises a series of removable plates of heat insulating material designed to be applied to the inside of the metallurgical container against the lateral walls and the bottom of the latter, at least a part of these plates being quadrangular and identical. The quadrangular and identical plates include on their two opposite edges a rib extending over a major fraction of the length of the corresponding edge, this rib defining a support surface designed to receive an identical rib formed along the adjacent edge of another plate. Each plate includes also, on the remaining fraction of the length of said edge, a protuberance defining a support surface oriented in the opposite direction with respect to that of the rib, the support surface of this protuberance being designed to receive an identical protuberance formed on the adjacent edge of another plate. The invention is particularly useful for the internal coating of casting distributors or tundishes.
