Analysis and control on the cause of tundish's nozzle clogging in casting ML35 steel

Weiqiang Zhang

Abstract

The cause of tundish nozzle clogging in casting KISC ML35 steel has been investigated and analyzed by X ray diffraction in connection with process analysis.The results show that the main cause of the clogging is inadequacy of Ca-treatment.Accroding to the investigation the process is optimized.As the result tundish nozzle clogging has been eliminated and the average heats of continuous casting increased from 8 heats/batch to 23 heats/batch and casting process stabilized thereupon.
