性を有している。[0003] In the heating furnace according to the present invention, most of the combustion gas generated in each unit furnace or zone is discharged to the outside through the heat storage body of the unit furnace or zone, and the adjacent other unit furnace or zone. Or it hardly flows into the zone. Thus, by adjusting the amount of combustion in each unit furnace or zone, the in-furnace temperature of each unit furnace or zone can be changed for each unit furnace or zone. And this change in furnace temperature occurs only in each unit furnace or zone,
Since it does not affect other adjacent unit furnaces or zones, it has the characteristic that the furnace temperature pattern of the entire heating furnace can be set freely as compared with a heating furnace having a conventional burner.

熱温度や加熱温度パターンを変える必要がある。However, in a heating furnace for steel, the temperature of an object to be heated charged in the heating furnace is distributed in a range from room temperature to several hundred degrees, and these are heated to the same temperature. It is necessary to change the heating temperature and the heating temperature pattern in accordance with the requirements of the product quality even if the temperature of the object to be heated is the same or the temperature of the object to be heated is the same.

いた。[0005] The heating furnace having the regenerative alternating combustion burner system is capable of setting the furnace temperature pattern for each unit furnace or zone as described above. When an object to be heated (high-temperature heating material) needs to be heated and then an object to be heated to low temperature (low-temperature heating material) is inserted, the amount of combustion increases to heat the high-temperature heating material. Heat is stored in the furnace body of the burned unit furnace or zone, and even if the combustion of the unit furnace or zone is stopped due to the low-temperature heating material, the temperature drops to a predetermined temperature suitable for heating the low-temperature heating material. It took a long time, and it was not possible to heat the low-temperature heating material at a predetermined temperature or heating pattern in a short time, which hindered improvement in work efficiency.

The temperatures 2c and 2d) are measured and controlled based on the relationship between the amount of combustion gas calculated from the thermal inertia of the unit furnace and the amount of temperature decrease (see FIG. 6). Further, since the O 2 concentration in the supplied combustion gas is low, the oxide scale of the object to be heated does not increase. Furthermore, since the combustion gas generated in the furnace is reused, it does not cause a cost increase as compared with the case where another gas is supplied.
