Description

Technical Field

[0001] The utility model relates to a molten iron ladle transportation device, in particular to a heat preservation transportation device for molten iron ladles. Background Art

[0002] A molten iron ladle is an essential container for receiving molten iron and smelting reactions in a steel plant. During the transportation of the molten iron ladle, due to the open top of the molten iron ladle, there is a large temperature difference between the molten iron ladle car and the external environment. The molten iron ladle car for receiving molten iron continuously radiates heat to the outside, resulting in serious heat loss of the molten iron. Especially in rainy and snowy weather, the heat loss is even more serious. Particularly in steel plants where the molten iron ladle car directly receives molten iron during the tapping of the blast furnace, the heat dissipation of the molten iron ladle car accounts for the vast majority of the heat loss of the molten iron during transportation. In subsequent processes, there are high requirements for the temperature of the molten iron. Usually, it is necessary to perform secondary heating treatment on the molten iron, wasting energy and time. In addition, due to excessive temperature drop of the molten iron, too much condensed steel slag precipitates, increasing material losses. Content of the Utility Model
