細は次に挙げる実施例に関連して説明することとする。Action: The firing work of the pottery furnace is performed at time points t 1 and t 2 as shown in FIG.
"Roast fired", "Proactive fired" in the period from the time point t 2, t 3, is divided into "Nerashi" between time t 3, t 4, the fuel supply is time t between
Refused at 3 . The firing operation there is a reduction firing performed in under a reducing atmosphere and an oxidizing calcination is carried out in under an oxidizing atmosphere, a reducing sintering atmosphere to "aggressive fired" in the period from the time point t 2, t 3 to reducing This is what you do.
The above-mentioned pottery furnace according to the present invention has the above-mentioned drawbacks of the conventional pottery furnace using a kerosene burner (a drawback that black smoke and a medium are generated during reduction firing, the time interval between time points t 2 and t 3 is 4 to 6 hours) is avoided by the cooperation of the distributor and the oxidative flame generator described above, and the details of the operation will be described in connection with the following examples.
