Abstract
The present invention relates to a method for repairing a protective lining of an industrial reaction or transport vessel, such as a converter vessel, electric arc furnace, or ladle. The method comprises identifying combined areas of the lining having a thickness below a predetermined threshold value by means of a measuring device, which measuring device measures the residual thickness of the lining and a processing unit, which processing unit in a first step transforms the residual thickness data into binary data, by comparing the measured residual thickness data with the predetermined threshold value for the thickness of the lining, and assigning the binary value '1' to areas of the lining having a thickness below the pre-determined threshold value, and the binary value '0' to areas of the lining having a thickness equal or higher than the pre-determined threshold value, or vice versa, in a second step combines isolated areas of the lining having a thickness below the predetermined threshold value into combined areas of the lining to which the binary value for areas of the lining having a thickness below the pre-determined threshold value is assigned, and in a third step computes the position and repair sequence of each of the combined areas and transfers these data to a repair device, and applying monolithic lining material onto the combined areas computed by the processing unit by means of a repair device.
