摘要

Heating process comprises pushing hot material through the furnace. Preferably a distance spacer is placed between two hot materials before being pushed through the furnace. Several distance spacers are joined together via couplings and/or connected to the pushing furnace. Scale formed on the hearth is pushed through the furnace using the distance spacer.
