Title: Research and development of secondary cooling heat transfer model for Baosteel 1930 mm slab continuous casting
Abstract:Based on the theory of two-dimensional non-steady-state heat transfer model and the law of heat dissipation in the secondary cooling zone of continuous casting,the heat transfer process in between the...Based on the theory of two-dimensional non-steady-state heat transfer model and the law of heat dissipation in the secondary cooling zone of continuous casting,the heat transfer process in between the neighboring pinch rolls is divided into four different processes,namely heat transfers(1) by pinch roll contact,(2) by steam evaporation,(3) by water flushing and(4) by radiation.In light of the current condition of Baosteel 1930 mm slab caster,the mathematical model of secondary cooling heat transfer in slab continuous casting has been developed.By using the object-oriented computer language Visual Basic 6.0,the computer simulation software of secondary cooling in slab continuous casting has been developed.The infrared ray temperature measurement has been conducted to validate the results of model.The difference between the measured slab temperature and calculated one is less than 20 ℃,and the deviation range is well controlled within 1.0 %~2.5 %.All this shows that the simulation model and results are good and reliable.By using the simulation software,the secondary cooling system of Baosteel 1930 mm slab caster can be researched and optimized for guiding the practical production.Read More
