Abstract: The granular insulation product is intended more particularly for the insulation, protection or processing of metal baths during their manufacture or transport. The product comprises a solid phase having a certain mineral matter content and an organic binder comprising cellulose-based pulp, and preferably paper pulp. The granulation is carried out under conditions such that the granules being formed experience no appreciable compression likely to break the structure of the solid phase containing the mineral matter.

Abstract: The heat insulating lining of the metallurgical vessel includes a permanent layer in a refractory material and a consumable layer arranged in the interior of the vessel and intended to be in direct contact with the liquid metal. This layer consists of a mixture of inorganic particles and of mineral and/or organic fibers embedded in an organic and/or inorganic binder. Between the permanent layer and the consumable layer is fitted a relatively compressible layer of an inorganic and/or organic fibre base resistant to the temperature pertaining at the contact of the consumable layer, these fibres being partially embedded in an organic and/or inorganic binder.

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: A pulverulent insulating and purifying covering (3) for the surface of liquid metal (2) contained in a metallurgical receptacle (1), comprises a layer (4) which includes at least one metallic oxide of basic character, capable of reacting with oxide inclusions contained in the liquid metal. This layer (4) covers a first layer (5) in direct contact with the liquid metal and including also at least one such metallic oxide and additionally a flux (6) in a quantity sufficient to render fluid this first layer (5) under the influence of the heat of the liquid metal (2). The metallic oxide is selected from the group consisting of lime, magnesia, calcium carbonate, magnesium carbonate, calcium hydroxide, magnesium hydroxide, dolomite and a mixture thereof. Each layer (4, 5) includes a mixture of lime and magnesia. The first layer (5) in contact with the liquid metal (2) includes a substantial amount up to 30% by weight of flux, while layer (4) which covers the first layer (5) is substantially free from flux. There is added, either continuously or periodically, to the first layer (5) flux sufficient to maintain the first layer in a fluid condition under the influence of the heat of the liquid metal (2). This can be done by feeding the flux through a conduit which opens below the lower surface of the second layer (4), for example by introducing the flux into a casting tube (9) through which the liquid metal (2) has been introduced into the metallurgical receptacle (1) , or by introducing the flux through both layers ( 4, 5) and into the liquid metal so that the flux rises to the underside of the first layer (5).

Abstract: There is applied on the internal wall of a metallurgical vessel a composition containing a carbonate of an alkaline-earth metal to which there has been added a certain proportion of refractory material in grains and this lining is heated in order to remove CO.sub.2 and in order to obtain an oxide layer of the alkaline-earth metal of porous structure. The proportion of refractory material is sufficient to endow the lining with sufficient resistance to erosion by the molten metal which is poured into the vessel. To be used for obtaining a purifying lining having good resistance to erosion from molten metal poured into the vessel.
