Abstract: Method for determining the state of a fire-resistant lining of a vessel containing molten metal in particular in which maintenance data, production data, and wall thicknesses at least at locations with the highest degree of wear are measured or ascertained together with additional process parameters of at least one identical/similar vessel after the vessel has been used. The data is collected and stored in a data structure. A calculating model is generated from at least some of the measured or ascertained data or parameters, and the data or parameters are evaluated using the calculating model using calculations and subsequent analyses. Thus, related or integral ascertaining processes and subsequent analyses can be carried out, on the basis of which optimizations relating to both the vessel lining as well as the complete process of the molten metal in the vessel are achieved.

Abstract: The invention relates to a refractory ceramic batch for the production of an unformed refractory ceramic batch, the use of a batch of this kind for lining metallurgical melting vessels and also a metallurgical melting vessel which is lined with an unformed refractory ceramic product based on a batch of this kind.

Abstract: A tap on a metallurgical vessel, in particular an electric arc furnace, is provided with a refractory end brick (6) that has an outlet opening (10). There is assigned to the lower face surface (11) of the end brick (6) a slot (15) which is shaped such that with the latter a tear-off edge (16) is generated on the outlet opening (10) when emptying the vessel. This slot (15) is annular in form and is provided here with a radially outwardly inclined inclined surface (18), and this tear-off edge (16) is thus formed immediately following the outlet opening (10). Thus, after each tapping process, the tap can be cleaned without manual assistance by shearing off with the front edge of the plate of the closure device.

Abstract: The invention concerns a batch for manufacturing a refractory ceramic product, a method for applying a gunning mass or casting mass to a surface, a method for manufacturing a refractory ceramic product, a refractory ceramic product as well as the use of a batch.

Abstract: The invention relates to a method for determining the state of the tap of a vessel (10) containing molten metal in particular. In the process, data of the fire-resistant lining of the tap (20), such as materials, wall thickness, type of installation, etc., is detected or measured and evaluated. Said data is then collected and stored in a data structure. A calculation model is generated from the data structure on the basis of at least some of the measured or ascertained data or parameters, and said data or parameters are evaluated by means of the calculation model using calculations and subsequent analyses. Thus, in addition to measurements, related or integral ascertaining processes and subsequent analyses can also be carried out for a metallurgical vessel in order to ascertain the current state of the fire-resistant lining of the tap of the vessel after the vessel has been used.
