Abstract
An apparatus for cooling hot steel plate and sheet has a plurality of cooling units disposed along the plate or sheet delivery line. Each cooling unit has a top and a bottom roll-and-nozzle assembly and a device for coupling them. The top and bottom assemblies each have a roll to restrain the plate or sheet and a nozzle to spray a coolant thereon. The coupling device has a screwdown mechanism to adjust the space between the top and bottom rolls and a device for adjusting the restraining force working on the plate or sheet being cooled. This cooling apparatus permits rapid cooling of steel plate and sheet without causing distortion thereof, and the apparatus is easy to maintain.
