Description

Technical Field

[0001] The utility model relates to the technical field of torpedo ladles, and specifically relates to a molten iron protection device that is convenient to operate. Background Art

[0002] When a torpedo ladle is in use, it is required to have good heat preservation performance to slow down the cooling rate of the molten iron inside, and prevent the physical properties of the molten iron inside from being affected due to too fast cooling or too large temperature difference.

[0003] The inside of the torpedo ladle is composed of three parts: a heat-insulating layer, a permanent layer, and a working layer. The combined action of these three parts plays a role in insulating the molten iron inside the torpedo ladle. However, during the actual operation process, when the molten iron is loaded into the torpedo ladle from the blast furnace, heat loss occurs due to contact with normal-temperature air; moreover, the temperature of the torpedo ladle is also close to normal temperature, and the molten iron will also reduce its temperature when contacting it; the erosion and scouring of the torpedo ladle refractory by the molten iron make the heat preservation effect of the torpedo ladle worse; due to reasons such as a long transportation process and complex operation, the heat loss of the molten iron is the most serious, and the flue gas in the molten iron will also pollute the environment.

[0014] 2. When the molten iron in the torpedo ladle is poured out, quickly close the steel furnace cover and the refractory material casting furnace cover to reduce heat loss. When transporting molten iron again, the heat loss when the molten iron contacts the torpedo ladle is reduced.
