The cooling plate 1 comprises a cast iron element having substantially the shape of a parallelepiped, embedded longitudinally extending tubes 3; 103 disposed vertically and parallel to one another and extending out of said element on a first side 2b; 102b of said element, and a protective sleeve 4a, 4b surrounding portions of said tubes extending out of said element. A second side of said element opposed to said first side has a waffle shape formed by rows of bosses 8; 108 evenly spaced apart transversely of said element. The bosses of a row define projecting surfaces 9; 109 comprising substantially aligned portions of a cylinder, said cylinders having axes substantially coinciding with axes of said tubes 3.

Cooling plates for blast-furnaces

The plate comprises a cast iron element of substantially parallelepipedic shape. Cooling tubes which are disposed parallel to one another, embedded in the element and extend longitudinally of the element, issue from the latter on the same main side, respectively in the upper and lower parts of the element, in a protective sleeve. The side of the element opposed to the main side from which the cooling tube issue has a waffle shape.

Cooling plate for blast-furnaces

This invention relates to a cooling installation for a blast furnace using stave coolers in which circulates a cooling fluid, these staves being arranged in successive superimposed rings along the internal wall of the shell of the blast furnace and being traversed by internal fluid circulation tubes, the internal tubes of two staves adjacent in a vertical plane being interconnected so as to define a network of vertical fluid circulation lines, wherein this network is connected at each of its extremities to an external circulation and fluid cooling circuit defining a pressurized forced closed circuit in which the cooling fluid is maintained in the liquid phase.
