SHIFTABLE TYPE HANG-CHANGING DEVICE, UNIT AND METHOD FOR CONSTRUCTING, DEMOLISHING AND ASSEMBLING FURNACE BODY IN BLAST FURNACE

摘要

PROBLEM TO BE SOLVED: To efficiently convey an existing furnace body by dividing the existing furnace body into a plurality of furnace body annular blocks from the furnace top part to the furnace bottom part. SOLUTION: At the lower end parts of four supporting columns 7 disposed at four corners of rectangular shape in the plane, a transporting carrier 23 for hang-changing device is inserted and disposed and also, the lower end surface of the supporting column is shifted as the cutting state from the ground by ascending the transporting carrier for hang-changing device and the lower end surface of the supporting column is made to be in the touching state to the ground by descending the transporting carrier for hang-changing device.
