Definitions

  • the present invention was made toeliminate the defects encountered in the prior art blast furnace cooling systems, and is characterized in that a number of staves are interposed-between the furnace bricks and the steel shell; and replaceable members are inserted from the exterior of the blast furnace into appropriate stave cooling portions so as to' extend inward beyond the inner surface of the furnace.
  • FIGS. 1 to 3 are explanatory views illustrating the conventional blast furnace employing the conventional staves for cooling the furnace;
  • FIG. 11 is a view similar to FIGS. 8 and 10 illustrating a further embodiment of the present invention.
  • each cooling plates 6 is scalable fixed bricks 2 may be prevented from falling off from the fur-.
  • the members (the metal plates 5 and the cooling plates 6) of a blast furnace cooling system are removably disposed between the staves or within the staves which in turn are interposed between the furnace bricks and the steel shell. Therefore, the bricks may be prevented from falling off from the furnace wall, and the upward blow of the high temperature gases between the furnace wall or bricks and the charge may be prevented even when the bricks are damaged,'so that the service life of the staves may become longer. Furthermore the members (the metal plates 5 and the cooling plates 6) may be immediately replaced with new ones when they are damaged, so that the service life ofthe staves may be increased. Therefore the productivity may be much improved with the conventional cooling systems.
  • a blast furnace as claimed in claim lwhe reln said metal plate extends inwardly into said refractory brick lining at least to the same extent as said cooling plate.
