The present invention relates to a heating furnace having a multi-chamber. The heating furnace having the multi-chamber comprises: a temperature increasing chamber which allows a material to be charged therein, increasing a temperature of the material to a first temperature; a temperature maintaining chamber which maintains the temperature of the material having a temperature increased in the temperature increasing chamber at a second temperature, thereby reducing a time required to heat the material and uniformly maintaining the required temperature of the material. |
