PURPOSE:To reduce each variation in the longutidinal direction and in the direction of width in the section of a bed by loading a plural kinds of materials on the basis of a bed compounding program. CONSTITUTION:When a plural kinds of ores A, B, and C are loaded onto a bed, the material having the average constituent of the whole on the bed or a prescribed constituent value close to the average constituent out of the above- described materials is loaded preferentially onto the core part 3 of the bed so that a nearly isosceles triangle form in is formed section. Then, other materials are loaded in the order where the loading speed per a prescribed constituent is increased or reduced, and thus the variation of the bed constituent is reduced, and the variation of the quality of sintered crystal is suppressed. |
