Aluminum concentration management method of temperature control and the molten zinc of molten zinc concentration and temperature estimation method and hot-dip galvanized in a pot of material components in the fluid system

摘要

PPROBLEM TO BE SOLVED: To provide a temperature and concentration estimation method of, even in a fluid system having a complicated flow field, estimating the temperature of entire fluid and the concentration of a substance component in the fluid system without imposing a restriction to the disposition of a temperature measurement device. PSOLUTION: This method includes: a temperature measurement step (step S701) of measuring fluid temperature even at the arbitrarily defined actual temperature measurement point of a fluid system; estimation steps (steps S702 to S704) of estimating temperature based on an index and measurement temperature at an arbitrarily defined temperature estimation point; a concentration measurement step (step S706) of measuring the concentration of a substance component at the arbitrarily defined actual concentration measurement point; and concentration estimation steps (steps S707 to S709) of estimating the concentration of the substance component based on the index and the measurement concentration at the arbitrarily defined concentration estimation point.
