Abstract

The invention provides a replacement method of a coiler mandrel. The method comprises a step of hoisting out an old mandrel and a step of reassembling a new mandrel. Research and on-site investigationand measurement find that a coil stripping trolley can still move for 2.1 meters toward the driving side under in the normal gate position, the distance can completely ensure that most part of a mandrel can be pushed out of a coiler rack, the hoisting requirement is met, and tedious dismounting when a coiler is moved out and complicated debugging when the coiler is moved back are omitted. Accordingly, a special tool used for supporting the mandrel to move when the coil stripping trolley horizontally moves the mandrel is mounted on the coil stripping trolley and is matched with an overhead crane, the purpose of replacement by moving out the mandrel under the assistance of the coil stripping trolley is achieved, and the mandrel replacement difficulty and strength are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of metallurgical construction, in particular to a method for replacing a reel of a coiler. Background technique [0002] At present, there are two general methods to replace the reel of the coiler; one is to lift the reel out after the coiler is moved horizontally, and the other is to use the guide chain, wire rope, etc. to lift the reel bit by bit. Derived from the ground, the defect of these two methods is that the operation is very cumbersome, not only wastes time, but also consumes manpower, and the difficulty and intensity of reel replacement are quite large. Contents of the invention [0003] In view of this, the present invention proposes a method for replacing a reel of a coiler, aiming at solving the problem of difficulty and high strength of the existing method for replacing a reel. [0004] The invention proposes a method for replacing a reel of a coiler, the method includes the following steps...
