Embodiment Construction

[0012] The method relates in particular to metallurgical furnaces. As an exemplary embodiment, the cross-section of one such furnace 10 is at figure 1 shown in . In this example, the furnace is a converter 10 known per se for the production of steel. The converter 10 basically consists of a metal shell 15, a refractory lining 12, valves 20 and gas sweep plugs 17, 18 which can be coupled to a gas supply (not detailed).

[0013] The molten metal poured into said converter 10 in operation is metallurgically treated, for example, by blowing (it will not be detailed here). Typically, several of said converters 10 are used simultaneously in a steelworks to produce steel, and data for each converter will be recorded.

[0014] The valve 20 is arranged in a side area of ​​the converter 10 and is used to discharge the molten metal which has been processed. The valve 20 is composed of a valve passage 21 , a sleeve-shaped valve block 22 forming the valve passage, and a metal discharge...

Abstract

The invention relates to a method for determining the state of a fire-resistant lining of a vessel (10) containing molten metal in particular. In the process, 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 a vessel (10) after the vessel (10) has been used. Said data is then 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 said data or parameters are evaluated by means of 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.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for determining the state of valves, in particular of metallurgical furnaces. Background technique [0002] There are various calculation methods for the construction of refractory linings for valves and furnaces, especially metallurgical furnaces, in which determined data or empirical values ​​are converted into mathematical models. Since these mathematical models are not sufficiently accurate to detect the effective wear mechanisms used in metallurgical furnaces or do not take such mechanisms into account, the possibility of mathematically determining the condition of the refractory lining and the condition of the valves and the maintenance of this lining is very limited. However, decisions regarding the refractory lining of the furnace or its valves, such as the refractory lining of a converter, must still be manually made. [0003] According to publication WO-A-03 / 081157, in a ...
