HEAT RADIATION PREVENTIVE LID OF MOLTEN IRON TRANSPORTING CONTAINER, HEAT RETAINING METHOD OF THE MOLTEN IRON TRANSPORTING CONTAINER, AND THE MOLTEN IRON TRANSPORTING CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a heat radiation preventive lid of molten iron transporting container capable of receiving molten iron while the lid is attached to the molten iron transporting container in order to suppress heat radiation from the molten iron transporting container in an empty condition, and heat radiation from the opening part of the molten iron transporting container, when receiving the molten iron; a heat retaining method for performing heat retention of the molten iron transporting container using the heat radiation preventive lid; and the molten iron transporting container with the heat radiation preventive lid mounted thereon.SOLUTION: A through-hole 4 for making molten iron pass therethrough when receiving the molten iron from a blast furnace, is formed in the thickness direction of a heat radiation preventive lid 1 placed on the opening part 6 of a molten iron transporting container 5 for receiving the molten iron from the blast furnace. The minor axis dof the through-hole 4 is smaller than the inside diameter dof the opening part 6 of the molten iron transporting container 5. The heat radiation preventive lid 1 is placed on the opening part 6 of the molten iron transporting container 5. The molten iron transporting container 5 is arranged at the molten iron receiving position for receiving the molten iron from the blast furnace. The molten iron is received from the blast furnace through the through-hole 4 into the molten iron transporting container 5 while the heat radiation preventive lid 1 is placed on the opening part 6.
