The most important concern regarding the use of coal combustion in transient processes, as encountered in reheating furnaces, is the justifiable compromise between computational expense and accuracy. Further, to the authors' knowledge, very few works have been reported for simulation with pusher type reheating furnaces [19].

Most hazards in rolling process arise from coming in contact with moving hot material, falling etc. Second threat is from emissions of reheating furnaces whichcontain toxic gases such as carbon monoxide, Sulphur dioxideNOx, etc. Also leakage of fuel gas like producer gas, Piped Natural Gas (PNG), Coal Bed Methane (CBM) etc is a constant threat. 2.

Reheating furnaces After the continuous casting (see Fig. 1), the metal is split into slabs, billets or booms, which must be reheated in reheating furnaces up to 1250 °C before milling. An example of recent furnace, with digital control and lateral burners is shown in Fig. 3. Fig. 3. Example of reheating furnace for slabs, with lateral burners.

For a reheating furnace, an analysis of thermal efficiency depends on precise investigations of the combustion and flow characteristics inside a furnace. Especially, the flow field of the hot gas has significant influence on heating slabs. The slabs are heated up to the temperature over 1500 K, and then they are transported to the rolling mill.
