Postheating soaking time recommendations

To achieve effective postheating, the entire cross-section of the plate must reach the target temperature, generally for all steel grades. A certain amount of time is required for the heat to spread throughout the plate. It's important to note that the surface should be maintained at the target temperature consistently during the soaking period. The graphs provided can be used to determine the required soaking time.

For example, when preheating a 100mm plate to 175°C from both sides, when a surface temperature of 175°C is reached, this temperature should be maintained for 11 minutes to ensure the core of the plate has the same temperature.

Required soaking time when heat is applied from both sides, for example heating in a furnace

Required soaking time when the heat is supplied from one side only, for example, heating with propane torches or heating with electrical mats
