METHOD FOR FORECASTING POSSIBILITY OF ADDITIONAL CONTINUOUS-CONTINUOUS CASTING ON CONTINUOUS CASTING PROCESS

摘要

The present invention allows for continuous casting to predict whether additional annual performance by predicting the degree of immersion nozzle clogging relates to an open play predictable method , the method comprising: measured by collecting in open play (heat) is set within the back-pressure pipe (Back Pressure) according to the argon gas to be supplied in accordance with the stopper , the argon gas is collected in the set open play calculating an argon gas back pressure ratio (x) by using a back pressure and a step of calculating the area ratio index in (y) the immersion nozzle by the argon gas ratio calculated by the back pressure , and calculated by the area ratio index (y ) and by predicting the log is large enough compared to the preset reference value and provides the step of predicting the performance , open to availability . ;
