Description
The cooling process of a hot steel plate in the forced cooling of the laminar water flow was experimentally and analytically discussed. The main results obtained in this paper are as follows: <BR>1) The heat transfer coefficient α of the forced cooling of the laminar water flow can be deduced as "α=500·(θS-θW)1/2" where θS and θW are the temperature of the cooled surface and the cooling water, rerspectively. <BR>2) The radius RB of the circular black zone can be described as " RB= a√t" where t is the cooling time and a is the constant determined by the water flow rate and the vertical distance between a nozzle exit and cooled plate surface. <BR>3) The cooling curve calculated at a given point in the steel plate using the heat transfer coefficient indicated in 1) agrees with the experimental cooling curve when the water cooling diameter RW is assumed to be " RW=a√t+ 10".
