This leads to severe damage to the converter and causes the production process to stop.<!--more--><\/p>\n<p style=\"text-align: justify;\">Due to the fact that the converters are used in high temperature conditions, so the possibility of cracking in them due to the activation of the mechanisms of degradation of steels at high temperatures is greatly enhanced. Accordingly, in the framework of the project to investigate the root causes of destruction, the technical and process causes of this destruction were
