Definitions
- the present invention relates to a method and an apparatus for easily sintering a silver clay compact.
- silver clay is obtained by mixing pure silver powder or silver alloy powder with a binder or the like.
- the silver clay compact obtained by molding and drying this silver clay into a predetermined shape is placed in a temperature-controllable electric furnace or gas furnace, heated and sintered to produce ornaments, etc. I do.
- the gas burner is used in an open state in principle, so the sintering of the silver clay compact is performed with the gas burner flame visible. It is.
- the gas burner's flame is often adjustable but adjustable, and is often ignited by shock, resulting in the use of gas, especially by women. And fear of gas burners, they may become less willing to make silver clay ornaments.
- a method of sintering by heating with a gas burner flame in a refractory container has also been proposed.However, in order to sinter the silver clay compact while moving the gas burner in the container, the space in the container must be increased. If not, the workability will decrease.
- the container becomes large, as a result, labor is required to install the container, and it is necessary to secure a space for storing the container after the sintering operation is completed.
- gas burners have the convenience of freely adjusting the state of the flame, it is difficult to adjust the temperature of the flame to the optimum temperature for sintering the silver clay molded body. However, the temperature often deviates from the optimum temperature for sintering the silver clay compact, and as a result, it was difficult to obtain a desired decorative product.
- the present inventors have studied to develop a method that can easily and easily sinter silver clay.

When applied directly to the silver clay compact, the silver clay compact can be easily sintered.
- Solid alcohol fuel is easy to handle because there is no need to use a lamp device with a core like liquid alcohol fuel, and the area of the burning part can be expanded in a disk shape, causing a flame. By expanding the area, it is possible to create a flame that wraps around the silver clay compact.
- This solid alcohol fuel is usually formed into a disk-shaped or column-shaped body having upper and lower planes having a relatively large area. Therefore, by igniting the relatively large upper surface, a relatively large soft flame is generated, and the relatively large soft flame can be sintered while wrapping the silver clay molded body.
- the solid alcohol fuel is burned in a sintering space surrounded by heat insulating material to prevent fluctuation of the flame of the solid alcohol fuel due to the breeze. preferable.
- the temperature inside the sintering space can reach 700 ° C or more relatively quickly, but can exceed 830 ° C. Absent. As a result, the temperature inside the sintering space is maintained at 700 to 800 ° C while the solid alcohol fuel is burning. Since this temperature of 700 to 800 ° C is the optimal temperature range for sintering silver clay compacts, a special temperature is required when sintering silver clay compacts using solid alcohol fuel. No adjustment is required.
