Abstract：The content of H2 in gas gives a big influence for convection transfer coefficient and temperature of strip in rapid cooling section of vertical continuous annealing furnace. The situation explains the relation between physical character of gas, transfer coefficient and temperature of strip. The heat transfer character of gas and strip was studied, the change of convection transfer coefficient and temperature of strip was analyzed. It calculates convection transfer coefficient and cooling temperature of strip with different content of H2 in gas, applied relations of equipment configuration parameters, Nusselt number and convection transfer coefficient of gas. The calculating method can offer certain basis for production and designing engineering projects.
