REFRACTORY BATCH AND USE THEREOF

摘要

The invention relates to a batch made of refractory mineral materials for lining of assemblies used for nonferrous metal melts, containing over 90% by weight of a mixture of the following constituents or very preferably consisting 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 bis 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.The invention further relates to the use of the batch for producing refractory products.
