Method for determining the state of the tap of a metallurgical vessel in particular

A method for determining the state of the tap of a metallurgical vessel in particular, wherein data of the refractory lining of the tap (20), such as materials, wall thickness, type of installation and others are detected or measured and evaluated, characterised in that the following measured or established data of each vessel (10) are collected and stored in a data structure, namely

• the initial refractory construction of at least the refractory lining of the tap (20), such as materials, material properties, wall thicknesses of the tap blocks (22) and/or injected materials as maintenance data;
• production data during use, such as amount of molten mass, temperature, composition of the molten mass or the slag and its thickness, tapping times, temperature profiles, treatment times and/or metallurgical parameters;
• additional process parameters such as the manner of pouring or tapping the molten metal into or out of the vessel;
• that a calculation model is generated from at least some of the measured or ascertained data or parameters, by means of which these data or parameters are evaluated by means of calculations and subsequent analyses.
