| Abstract Scope |
Accelerated cooling on the run-out table of a hot rolling mill plays a key role to tailor microstructure and properties of steel products. In order to develop a heat transfer model for predicting the temperature evolution of steel plates during run-out table cooling, systematic experimental studies have to be carried out to determine the effect of various processing parameters on heat extraction. In the present study, a series of experiments was conducted using a planar water nozzle to study the effect of water flow rate (100 to 250 L/min) and temperature (10 to 40°C) on the heat transfer rate for stationary plates. Temperature data were recorded at different locations from the stagnation line using intrinsic thermocouples and heat fluxes at the top surface were subsequently calculated. These experimental results provide the basis to develop heat extraction relationships as an upper limit for slow moving plates. |
