High-temperature modeling of hot metal tapping from the converter with argon supply to the tap hole cavity
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 5
Abstract
High-temperature modeling of tapping from the converter with different processing modes of metal flow by argon is carried out. Experiments are conducted on the basis of steel-making laboratory of department of ferrous metallurgy of Dniprovsk State Technical University. The obtained data are indicative of the possibility of gas-metal flow formation with different arrangement levels. The laws of impact of tap hole geometrical dimensions and consumption characteristics of inert gas on flow arrangement are established. The reasonability of two-chamber tap hole for metal flow processing by argon is shown. The authors defined that in case of flow processing by argon with consumption of 1 m3/t with using the two-chamber tap hole, the gas-metal flow possesses high-level arrangement and moves in line with protective gas. This is conductive to the process of carbon deoxidation not only in gas-feeding zone, but also in the open area of jet. The peculiarities of behavior of liquid metal particles of various sizes in the argon flow out of tap hole are studied with the use of video recording.
