Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of molten iron transportation, in particular to a molten iron ladle covering device and a molten iron ladle car. BACKGROUND

[0002] In the metallurgical industry, the molten iron produced in the ironmaking process is generally contained in a molten iron ladle and transported to the next process by a molten iron ladle car. During transportation, the molten iron ladle on the molten iron ladle car is generally open, which easily leads to heat loss of the molten iron, a decrease in the temperature of the molten iron, and an increase in energy consumption of the next process. At the same time, if the molten iron splashes, it may cause a safety accident, especially when transporting over a long distance in the rain. If the molten iron comes into contact with rainwater, an explosion may occur, causing a serious safety accident.

[0003] Therefore, it is necessary to design a molten iron ladle covering device and a molten iron ladle car to reduce the problem of increased energy consumption caused by heat loss of the molten iron and to avoid safety problems caused by splashing of the molten iron.
