Description

Cover moving device Technical Field The utility model relates to the technical field of blast furnace metallurgical equipment, in particular to a cover moving device. Background At present, with the development of blast furnace metallurgical technology, a blast furnace tapping system is continuously optimized and perfected, the intracranial pressure of the blast furnace is continuously increased, the tapping amount of a tapping field is increased, and molten iron splashing is larger during tapping, so that the method is suitable for increasingly severe environment protection situations, improves the working environment in front of the blast furnace, reduces the damage of heat radiation to other equipment such as tapping machines, mud guns and the like, and a cover moving machine is developed. The cover moving machine is covered above the iron runner after the tapping field tapping machine finishes the operation and returns to the original position, so that dust and iron slag generated during tapping are prevented from splashing everywhere, meanwhile, production staff can approach the furnace door to perform slag removal and other works on the tapping hole when tapping is about to be finished, protection effects are achieved on tapping equipment in front of the furnace, the cover moving machine is required to be moved away before tapping, the tapping machine can work, the cover moving machine is required to be moved away after tapping is finished, and the gun can be used for blocking eyes.
