It tends to reduce the intended performance of the device. Taking a heating furnace or a soaking furnace as an example, a scale layer deposited on the hearth worsens the combustion situation in the furnace, which causes uneven heating of the slab, resulting in dimensional accuracy and shape defects after rolling. Become like Therefore, it was necessary to periodically remove the scale layer deposited in the furnace.

After cooling the furnace down to about 50 ° C,
Dozens of workers per furnace entered the furnace, excavated the scale layer using a pickaxe or rock drill, etc., and manually discharged the excavated scale outside the furnace. Since the latent heat inside the scale is released by excavation of the scale layer, it is inevitable that the temperature inside the furnace will rise again. Therefore, the work in the furnace is limited to a few dozen minutes at a time, requiring constant replacement. As a result, the furnace shut down time was prolonged, a large amount of labor had to be secured, and work efficiency was poor.
