A numerical study on the transient heating of a cast iron slab in a car-hearth furnace is presented. The influence of the direction of jets issuing from the burners on the velocity and temperature fields during the heating period was investigated. The standard k-t turbulence model is used in the present study. It is found that the direction of the jets has a significant influence on the temperature distribution in the slab. It is also shown that inclined jets produce a more uniform temperature field and that the time needed for the slab to reach a predetermined temperature can be significantly reduced which results in the reduction of energy consumption.
