摘要

abstract filler of mineral refractory materials for a nonferrous metal melting aggregate coating; process for producing a refractory product using a filler; and brick produced the invention relates to a filler of mineral refractory materials for a nonferrous metal melt aggregate coating containing more than 90% by weight of a mixture of the following components or most preferably composed of the following components: 74% by weight of at least one coarse-grained olivine feedstock having a forsterite content of at least 70% by weight and having a particle size of 50% by weight greater than 0.1 mm - 25 to 49% by weight of at least one magnesia in the form of flour with a particle size of 50% by weight? 1 mm - 0,9 to 14% by weight of at least one silicon carbide (sic) in the form of flour with a particle size of 50% by weight? 1 mm - 0.1 to 10% by weight of at least one fine particulate dry powder silicic acid with particle size? 500 µm - 0 to 4 wt.% Of at least one known antioxidant for refractory products - 0 to 4 wt.% Of at least one additional refractory feedstock granule known per se, in particular having 0% particle size by weight, in particular 80% by weight, preferably 100% by weight, greater than 0.1 mm - 0 to 2% by weight of at least one additive known per se for the production of refractory fillers - 0 to 4% by weight of at least one known self-contained refractory material in flour form and / or in the form of so-called medium grain and / or so-called coarse grain - 0 to 10% by weight of at least one known binder for refractory products, for example in dry form or added in liquid form. The invention further relates to the use of filler in the manufacture of refractory products. 1/1
