摘要： A molded, fireproof product, which contains graphite, in particular natural graphite, and is based on fireproof granular materials. The granular-material grains of the product are consolidated to form a molded body by means of a binder known per se and/or ceramic bonding. The product has a homogeneous mixture of at least two graphite types, which each have a different coefficient of thermal expansion. One graphite type is predominant by amount and the other graphite type acts as an auxiliary graphite type. The invention further relates to a method for producing a product and to the use of the product.

摘要： A refractory has the form of a dry, mineral batch of fire-resistant mineral materials combined in such a way that refractories which are long-term resistant to fayalite-containing slags, sulfidic melts (mattes), sulfates and non-ferrous metal melts and are used for refractory linings in industrial non-ferrous metal melting furnaces can be manufactured. The refractory at least contains: —at least one coarse-grained olivine raw material as the main component; —magnesia (MgO) meal; —at least one fire-resistant reagent which, during the melting process, acts (in situ) in a reducing manner on non-ferrous metal oxide melts and/or non-ferrous metal iron oxide melts and converts same into non-ferrous metal melts.

摘要： There is a process for creating graphite free non-fired refractory products, which are molded using presses and which includes using a plurality of different binders. The binders comprise a first binder for binding grains of granulation between room temperature and 400° C., a second binder binding the grains of granulation between 300 and 900° C.; and a third binder binding granulations of the refractory materials that enter into ceramic binding at temperatures above 900° C. This process is for producing at least one of magnesia chromite bricks, magnesia spinel and spinel bricks, magnesia zirconia and magnesia zircon bricks, magnesia hercynite and magnesia galaxite bricks, dolomite, dolomite-magnesia, and lime bricks, forsterite and olivine bricks, magnesia forsterite bricks, magnesia pleonast bricks, magnesia bricks. These products are configured to operate as a fire-side, refractory lining of large-volume industrial furnaces operated with an essentially oxidizing atmosphere, for the production of cement, lime, magnesia, and doloma.
