Reduction in the Accident Rate in Casting Steel in the CCM
The work represents the analysis of the influence of defects of the gripping devices of the CCM upon appearance of emergency situations at the initial stage of casting. Stressed-deformation strain state of metal in the head [part of the gripping device of continuous casting machine was analyzed. The analysis shows that residual strain of the head part of the gripping device can lead to an increase of the value of friction forces against the walls of crystallizer and alternations in the heat removal intensity. It may be on of the reasons of creation of emergency situations.
