Background
The steel ladle is used as a steel container between a steel making process and a continuous casting process, and the pouring temperature of molten steel must be strictly controlled within a castable range in order to ensure the normal production and the product quality of continuous casting steel billets. There are two main ways for the heat loss of molten steel: firstly, refractory material absorbs and stores heat of molten steel; secondly, the heat conduction and the heat radiation between the molten steel and the air are directly realized. For a 150t ladle as an example, the heat loss from the liner to the air by radiation within the first 20min after the start of the empty ladle will result in a loss of up to 15 ℃ in the temperature of the next furnace of molten steel, with 40% of this heat loss occurring in the first 5min after the start of the empty ladle. In the turnover process of the steel ladle, the time of the steel ladle at a non-treatment position accounts for more than half of the total turnover period, so that the heat preservation of the steel ladle and molten steel is very important for ensuring the pouring quality or controlling the cost.
