Study on the Law of Concurrent Heating of Blast Furnace Slag by Taking Iron Tailings as Conditioning Agents

Abstract

Based on the heat balance principle, and by using thermodynamic software FactSage6.4 simulation software, the study analyzed the impact of the ratio of iron tailings on the thermodynamic parameters of slag system, and explored the blast furnace slag and iron tailings and the change rule of heat transfer between the blast furnace slag and iron tailings and the influence law of the ratio of iron tailings on the temperature and concurrent heating quantity of the slag system; the study further adopted the least squares method, multiple regression analysis method to establish the mathematical model of the temperature drop ΔT and concurrent heating quantity of the slag system; Based on the above research, the study constructed the coordinated control chart of the ratio of iron tailings, the temperature of slag fluidity, and concurrent heating quantity so that the law of concurrent heating of the slag system by taking the iron tailings as conditioning agent was obtained.
