Abstract
(EN)
The present invention makes it possible to suppress variations in the weight of a high viscosity substance at each extrusion of the high viscosity substance and each cut-off to the extent possible. Metallic sodium (5) filled into an extruder main body (3) is extruded from a nozzle (7) of the extruder main body (3) by a pressing tool (4), and when extrusion of the metallic sodium (5) to a prescribed position is detected, movement of the pressing tool (4) is stopped and then the extruded metallic sodium (5) is cut. In this instance, the impulse (P) after stopping until the load ceases to act on the metallic sodium (5) within the extruder main body (3) after the movement of the pressing tool (4) has stopped is made to approach a constant value by adjusting the speed of movement of the pressing tool (4).
(FR)
La présente invention permet de supprimer les variations de poids d'une substance à viscosité élevée à chaque extrusion de la substance à viscosité élevée et chaque tronçonnage dans la mesure du possible. Selon l'invention, du sodium métallique (5) introduit dans un corps principal (3) d'extrudeuse est extrudé à partir d'une buse (7) du corps principal (3) de l'extrudeuse au moyen d'un outil de pressage (4) et lorsque l'extrusion du sodium métallique (5) en une position prescrite est détectée, le déplacement de l'outil de pressage (4) est arrêté et ensuite le sodium métallique (5) extrudé est coupé. Dans ce cas, l'impulsion (P) après l'arrêt jusqu'à ce que la charge cesse d'agir sur le sodium métallique (5) à l'intérieur du corps principal (3) de l'extrudeuse après que le déplacement de l'outil de pressage (4) s'est arrêté est amenée à s'approcher d'une valeur constante par réglage de la vitesse de déplacement de l'outil de pressage (4).

高粘性物質の各押出しにおいて、各切断される高粘性物質の重量がばらつくことを極力抑制する。押出機本体(3)内に装填された金属ナトリウム(5)を押圧具(4)により押出機本体(3)のノズル(7)から押出し、金属ナトリウム(5)所定位置に至るまで押出されたことを検出したとき、押圧具(4)の移動を停止した上で、押出された金属ナトリウム(5)を切断する。この場合、押圧具(4)の移動停止後、押出機本体(3)内における金属ナトリウム(5)に荷重が作用しなくなるまでの間の停止後力積(P)を、押圧具(4)の移動速度を調整することにより、一定値に近づける。
