ADDITIONAL COLUMN FOR CHECKER BRICK RECEIVING METALLIC MATERIAL, CHECKER BRICK RECEIVING METALLIC MATERIAL AND COLUMN ADDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an additional column for checker brick receiving metallic material capable of corresponding high temperature by increasing heat storage amount of a checker brick, reducing running cost and shortening work period, a checker brick receiving metallic material and a column adding method.SOLUTION: There is provided a checker brick receiving metallic material 10 having a lattice metallic material 20 receiving a checker brick of a hot blast stove 2 and an existing column 40 arranged between the lattice metallic material 20 and a furnace bottom surface 21, a coaxial additional column 50 arranged in outside of the existing column 40 coaxially, the coaxial additional column 50 has a column body 51 arranged in outside of the existing column 40 coaxially and a height adjustment mechanism 59 for adjusting height of the column body 51, the column body 51 has a plurality of column cylindrical bodies 52 piled up in a height direction.SELECTED DRAWING: Figure 6
