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.

摘要： A method for producing a granular material from sintered magnesia by sintering of pressed articles, in particular pellets, from MgO powder, preferably from caustic MgO powder, and subsequent mechanical comminution of the pressed articles, the sintering being carried out in such a way that the granular material has a grain porosity (total porosity), according to DIN EN 993-1:1195-04 and DIN EN 993-18:1999-01, of from 15 to 38 vol %, preferably 20 to 38 vol %. Also, a batch for producing a coarse ceramic, refractory, shaped or unshaped product containing the porous sintered magnesia, to such a product produced from the batch and to a method for its production, to a lining, in particular a working casing and/or a backing, of a large-volume industrial furnace, the lining, in particular the working casing and/or the backing, having at least one such product, as well as to such an industrial furnace.
