摘要
The present invention relates to a continuous-continuous casting feasibility prediction method in continuous casting, which predicts the feasibility of additional continuous-continuous casing by predicting the degree of clogging of an immersion nozzle during continuous casting; and provides a step for collecting the back pressure from the predetermined continuous-continuous casting by actually measuring the back pressure in a pipe generated by argon gas that is supplied along a stopper; a step for calculating the back pressure ratio (x) of the argon gas by using the back pressure of the argon gas collected from the predetermined continuous-continuous casting; a step for calculating the area rate index (y) inside the immersion nozzle by using the calculated back pressure ratio; and a step for predicting the feasibility of continuous-continuous casting by predicting the degree of clogging by comparing the calculated area rate index with a predetermined reference value.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) Start;(BB) End;(S10) Supply argon gas through a stopper during casting;(S11) Measure the back pressure values of initial argon gas from a first continuous-continuous casting and a fourth continuous-continuous casting;(S12) Calculate a gas back pressure ratio using the argon gas back pressure values;(S13) Calculate an area rate index using the gas back pressure;(S14) Estimate a clogging degree by comparing the area rate index and a reference value;(S15) Predict the feasibility of additional continuous-continuous castings
