Abstract: A submerged guide member for guiding a strip of metal in a molten metal coating bath in the form of a roller or fixed guide consisting of sintered, fused or vitreous silica or a mixture of at least 80% by weight of fused or vitreous silica and up to 20% by weight of one or more members of the group consisting of refractory earth elements, metal oxides and compounds of oxides, carbides, borides, oxynitrides, SiAlON, thermal decomposition products of carbosilanes, calcia, magnesia, zircon (ZrSiO.sub.4), zirconia, chromia and silicon carbide. The process concerns the deposition of a protective layer of, for example, zinc on a strip of sheet metal by submerging the metal strip in a bath of molten metal or metal alloy, and guiding the strip with one or more submerged rollers or fixed guide members of the fused silica material set forth above.

Abstract: The invention concerns a new material for molding elements as well as the molds produced in this manner. This material contains more than 30% vitreous fused silica and various adjuvants and binders and presents the advantage of the possibility of modulating the thermal conductivity of the molds. Application to all types of industries utilizing shaping by molding of liquid or paste-like materials, or by the hot deformation of flat products.

Abstract: The invention concerns a composite material for a receptacle for transferring molten metal.It is comprised of a refractory material and a frame chosen in the group comprised of mineral refractory wires and metallic wires.Application to the foundry industry.
