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.
