METHOD AND APPARATUS FOR CONTROLLING THE HEAT TRANSFER OF LIQUID COOLANT IN CONTINUOUS CASTING

摘要

A method is provided for continuously controlling the heat exchange capacity of a liquid-gas mixture which is a liquid containing gas bubbles or a gas containing droplets of liquid, said method comprising the steps of: detecting the relative density of said bubbles or droplets: comparing said relative density to a reference density range; and varying the amount of gas in said liquid so that said relative density is within said reference range.
