PURPOSE: An excessive oxygen supplying apparatus for a continuous annealing simulator is provided to control the supplying amount of excessive oxygen into the simulator heated at high temperature. CONSTITUTION: An excessive oxygen supplying apparatus(50) for a continuous annealing simulator comprises a heating furnace, a combustion pipe(55c) a liquefied natural gas(LNG) feeder, an air feeder, and a controller(58). One side of the heating furnace is connected to the continuous annealing simulator for increasing the temperature of the continuous annealing simulator. The combustion pipe is located in a hollow hole inside the heating furnace, and burns LNG by mixing with air. The LNG feeder is connected to the other side of the heating furnace. The controller controls the flow of the LNG and the air by being connected to the LNG feeder and the air feeder. |
