Abstract: A method for maintaining the optimal argon injection flow rate which will result in production of steel slab of a chosen alloy having optimal cleanliness. The steel is cast using an argon injected slide gate. The selected steel has a known optimal argon injection flow rate Qb* for casting steel of optimal cleanliness. The method involves calculating the present steel pressure and determining the present injection flow rate conductance Gb′ of the argon injected slide gate during either of 1) a steel pressure change event; or 2) an argon flow change event. The measurements are used to calculate present argon pressure required to insure the required injection flow rate of argon into the steel for optimal cleanliness of the cast steel.
