Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace steelmaking, in particular to a double-end pure electric drive rail torpedo type molten iron ladle car. Background Art

[0002] Molten iron ladle cars are also called molten iron transport cars. The molten iron ladle cars widely used at home and abroad are mainly divided into two types: ordinary molten iron ladle cars and torpedo-type molten iron ladle cars. Torpedo-type molten iron ladle cars are horizontally longer torpedo-shaped molten iron ladle used in large blast furnaces, also known as mixed iron cars. Molten iron ladle is also called iron ladle, iron ladle, iron barrel, which is specially designed for steelmaking furnaces. Therefore, there are many types of molten iron ladle according to capacity, but the shapes are similar. Compared with most industrial furnaces in steel mills, the molten iron ladle has a simpler structure and the lining material requirements are not high. Generally, high-aluminum, aluminum-carbon or aluminum silicon carbide refractory materials are used. The construction sequence is: bottom permanent layer, wall permanent layer, bottom working layer, and wall working layer. The construction machine is a special hydraulic lift. The permanent layer of the molten iron ladle has a brickwork structure and is also cast. The bottom and wall working layers are generally brickwork. There are two methods of brickwork for the wall working layer: ring laying and spiral laying.
