Simulation of Nozzle Clogging during the Continuous Casting of Aluminum-Killed Steel

Abstract

Nozzle clogging is a common problem associated with the casting of aluminum-killed steel. for this reason, a casting simulation apparatus was designed to measure the effect of metallurgical and refractory factors on nozzle clogging. Measurements taken with the apparatus were used to calculate a clogging factor (CF). the CF provides a quantitative method of evaluating the rate of accretion formation. This paper evaluates the effect of aluminum level, holding time before casting, and nozzle diameter on clogging. Microscopy of nozzles used in the simulation indicated that the accretions in the simulation nozzles were reasonably similar to those found in industry.
