摘要： PURPOSE: To make the highest possible utilization of the space possible in a tray by interposing thin films between the green compacts to be arrayed in the tray and sintered.
CONSTITUTION: In arraying circular cylindrical green compacts 1 on a tray 2, paper 3 as a thin film is inserted between each row in a transverse (lateral) direction, and the green compacts 1 of the adjacent rows adjoin to each other via the paper 3 with a shift corresponding to the half diameter thereof. The adjacent green compacts in the same row are arranged to the extent of contacting with each other lightly. Such green compacts are fed in a longitudinal (vertical) direction, and are sintered in a nonoxidative atmosphere of endothermic gas or gaseous ammonia. In this case, the paper 3 carbonizes but remains in the form of thin films and therefore the binding between the powder moldings of the adjacent rows is prevented. The powder moldings in the same row are bound in one row and since bound points 4 are two points at most, they can be easily parted by a small force. Since the feeding into the furnace is performed in the longitudinal direction of the row, there is no possibility of causing sticking at points 4.

摘要翻译：目的：通过在要排列在托盘中的生坯和介质之间插入薄膜，尽可能最大限度地利用托盘中的空间。构成：在托盘2上排列圆柱形绿色压块1时，作为薄膜的纸3以横向（横向）方向插入每排之间，并且相邻行的生坯1经由纸3彼此相邻其移位对应于其半径。相邻行的相邻的绿色压块被布置成彼此轻微接触的程度。这种生坯在纵向（垂直）方向上进料，并在吸热气体或气态氨的非氧化气氛中烧结。在这种情况下，纸3碳化，但保持为薄膜的形式，因此防止相邻行的粉末成型品之间的结合。同一行中的粉末成型品一行结合在一起，由于结合点4最多为两点，因此它们很容易被小力分开。由于沿排的长度方向进入炉内，所以不可能在点4处发生粘附。
