FEUERFESTER VERSATZ UND SEINE VERWENDUNG
A batch made of refractory mineral materials for lining of assemblies used for nonferrous metal melts, contains over 90% by weight of a mixture of the following constituents:—from 3 to 74% by weight of at least one coarse-grain raw olivine material with at least 70% by weight forsterite content and having grain sizes of 50% by weight over 0.1 mm—from 25 to 49% by weight of at least one ground magnesia with grain sizes of 50% by weight≤1 mm—from 0.9 to 14% by weight of at least one ground silicon carbide (SiC) with grain sizes of 50% by weight≤1 mm—from 0.1 to 10% by weight of at least one fine-particle dry pulverulent silica with particle sizes≤500 μm—from 0 to 4% by weight of at least one antioxidant known per se for refractory products—from 0 to 4% by weight of at least one additional granulated refractory raw material known per se, more particularly having grain sizes of 50% by weight, in particular of 80% by weight, preferably of 100% by weight over 0.1 mm—from 0 to 2% by weight of at least one additive known per se for the production of refractory products from batches—from 0 to 4% by weight of at least one additional substance known per se made of ground refractory materials and/or in the form of what is known as medium-grain-size material and/or of what is known as coarse-grain-size material—from 0 to 10% by weight of at least one binder known per se for refractory materials, e.g. in dry form or in ancillary packaging in liquid form.
