Abstract
A statistical investigation was carried out to clarify the relations among the various factors influencing the conditions of cupola operation.
In this experiment a water cooled hot blast cupola was operated in basic condition and specially selected steels with uniform contents were charged. The operating conditions were maintained unchanged during the operation.
The data on various factors were obtained continuously extending over 2 hours during an operation.
From the results of the process analysis, several influencing factors were found to be the height of coke bed, CO2 content in top gas and the tapping speed and temperature as the information factors, and to be the temperature of hot blast as the controlling factor.
