The specific embodiment
Below describe preferred implementation of the present invention in detail.
Fig. 1 is the profile of expression embodiments of the present invention, the 1st, utilize pillar 2 and supported up body of heater, and the 3rd, chassis.The following of body of heater 1 opens wide.Chassis 2 utilizes and has omitted the below vertically lifting of illustrated elevating mechanism from body of heater 1 with original same.Chassis 3 is formed with shelf 5 on the platform 4 of centre, load to be sintered thing W.In addition, around it, form the siege 6 of level.In the present embodiment, siege 6 is heating resisting metal systems.
Shown in amplifying among Fig. 2, Fig. 3, in the present invention, the sealing ring 7 that seals between body of heater 1 and the chassis 3 is set in the body of heater lower face side.That is, in the present embodiment, the box 8 of heating resisting metal system is set in the bottom of body of heater 1, at its lower surface, inner seal circle 7a and outside sealing ring 7b give prominence to downwards and are provided with certain interval.These sealing rings 7 are stable on heating, support its both sides with metallic plate 7c.Inner seal circle 7a closely contacts with the upper surface of siege 6 when chassis 3 rises with outside sealing ring 7b, forms seal cavity.
As shown in Figures 2 and 3, between inner seal circle 7a and outside sealing ring 7b, be provided with sealing gas supply hole 9 with institute's determining deviation.In the present embodiment, sealing is formed at the bottom surface of box 9 with gas supply hole 9.As shown in Figure 1, on this box 8, be connected with, in seal cavity, supply with for example sealing gas of 1.5kPa with gas supply hole 9 from sealing as the pipeline 10 of sealing with gas supply nitrogen.
