Problems solved by technology
[0003] In the actual production process, since the weight of cover A is about 20 tons, if there is a failure of the cover remover, or the position of cover A shifts on the main ditch, so that the cover remover cannot hook the lifting lug on the ditch cover, it will be difficult on site. There are other ways to remove the A cover, resulting in the mud gun machine being blocked by the A cover and unable to block the iron hole, resulting in a major production safety accident

The invention relates to an emergency cover moving system, kit and method for a main iron runner cover A, and belongs to the technical field of ironmaking blast furnace operation. The emergency covermoving system comprises a first fixed pulley and a second fixed pulley; the first fixed pulley is fixedly arranged at the side, away from a main runner, of the cover A; the second fixed pulley is arranged at the side, away from a blast furance, of the cover A; and the emergency cover moving kit comprises the emergency cover moving system and further comprises a traction rope and a plurality of rolling rods. The emergency cover moving method provides the emergency cover moving kit and comprises the following steps that the traction rope sequentially winds around the first fixed pulley and the second fixed pulley, a crane lifts the end, away from the blast furnace, of the cover A, the rolling rods are placed between the cover A and the main runner, the traction rope winds around the second fixed pulley, and the crane drives the cover A to move towards the hoisting range of the crane. An existing casting house crane is utilized, the cover A can be moved emergently, production accidents caused by the fact that an iron notch cannot be blocked are avoided, accident handling cost is reduced, and machine tool preparation time is shortened.
Description
technical field [0001] The invention belongs to the technical field of ironmaking blast furnace operation, and relates to an emergency cover removal system, a kit and a method for a main iron ditch A cover. Background technique [0002] In the design process of modern blast furnaces, in order to reduce the flue gas produced by blast furnace iron tapping and the heat radiation of molten iron in the main ditch of the blast furnace, a ditch cover is usually set above the main ditch. The trench cover is generally divided into four sections A, B, C, and D, wherein the covers B, C, and D are hoisted in place by the driving of the casting yard. see figure 1 , because the A cover is located under the tuyere platform, it cannot be hoisted by the driving of the casthouse. Therefore, a hydraulic cover shifter is usually provided to shift the A cover. Cover A stands still on the side of the main ditch when the iron is not being tapped. After the tap hole machine has opened the tap ho...
