Abstract

Many studies have been performed to improve the quality and Cleanliness of steel ingots produced by Continuous casting process. One of the important defects is entrapping of mold lubricant powder in the ingot. In the paper, the mathematical modeling methods and Computational fluid dynamic (CFD) were used to investigate the powder fluid behavior during Continuous casting of steel. For this purpose, the factors of Powder entrapping and the behavior of the powder in the melt were investigated and some solutions were proposed to prevent these defects. Therefore, the boundary and initial conditions were studied in developed model and the effect of each one were investigated. The results showed that it can be possible to prevent the Powder entrapping in the steel ingot by decreasing the casting speed from 0. 9 to 0. 76 m/min, increasing the nozzle dip depth from 130 to 140 mm, decreasing the nuzzle diameter from 42 to 36mm, decreasing the powder particles size from 500 to 63 micrometers and by pouring of clean steel melt without the large inclusions.
