Temperature regulating agent as well as preparation method and application thereof

The invention particularly relates to a temperature regulating agent and a preparation method and application thereof, and belongs to the technical field of molten steel smelting, the temperature regulating agent comprises the following raw materials in percentage by mass: 50-80% of ball-milled granular iron, 20-40% of fuel, less than or equal to 5% of binder and less than or equal to 10% of auxiliary material; fuel and ball-milled granular iron generated in the 40 slag steel ball milling and washing process are used as main raw materials, by adjusting components and proportions of all the raw materials, the ball-milled granular iron is mainly composed of TFe, the fuel is mainly composed of fixed carbon, part of auxiliary materials are added, the cost is reduced, and the prepared temperature adjusting agent can meet the converter steelmaking requirement; and the manufacturing cost of the converter is reduced while the molten steel cooling speed of the converter is reduced and the high-value utilization of the
