Abstract: A metallurgical tilting vat, such as a steel mill converter, which, by means of vat extensions or projections, rests on a surrounding tilting mechanism, so that it can be tilted 360.degree., and where radial and axial heat expansion and contractions are accommodated. The tilting mechanism is equipped with dynamic test cells for weighing the vat and/or vat contents. This type of metallurgical tilting vat equipped with weighing devices serves to ascertain the vat contents in order to observe the steel production process based on differing weights of the vat contents, and, in turn, to regulate the decarbonization process based on the weight data and/or data graphs thus obtained.
