Abstract
Coils of metal strip are cooled by being placed on porous supports with the coil axes vertical. Water is introduced into the coil interiors and most of the water overflows the coil tops and thereby cools the coil tops and peripheries. A small proportion of the water flows out through the porous supports and thereby cools the bottom ends of the coils. The water is preferably introduced from below. Apparatus for performing cooling is disclosed.
Claims7
A method of cooling a coil of metal strip, in which said coil is placed, with its axis substantially vertical, on a porous support with the lower face of the coil standing on the support, introducing a stream of water into the interior of the coil to fill the said interior, a minor proportion of the water flowing from the coil interior along the said lower face by way of the said support, and a major proportion of the water flowing over the upper face of the coil and over the peripheral surface of the coil.
Apparatus for cooling cylindrical coils of metal strip, comprising a support grid, liquid coolant discharge means associated with the support grid, at least one cylindrical coil support plate supported by the grid and defining at least one cylindrical coil position, at least one liquid coolant supply aperture at each said cylindrical coil position, liquid coolant supply means communicating with said at least one liquid coolant supply aperture for delivering liquid coolant to the interior of a cylindrical coil standing at said cylindrical coil position, and a porous cylindrical coil support at each said cylindrical coil position providing a radial flow path for the liquid coolant across the bottom surface of said cylindrical coil.
