熱を施こせば、加工歪が除去されるとともに一部融着が
生じる等の効果によってきめて強化な結合が得られる。The molybdenum wire is knitted by a usual method and apparatus such as plain weaving and twill weaving to form a net as a single product. A plurality of nets obtained in this manner are superposed and pressed from both sides. This pressurization is for plastically deforming the plurality of superimposed nets so that they are in close contact with each other. Pressing is also possible, but it is practically preferable to use rolling milling. This roll processing is preferably performed at a roll interval of about 1/2 of the total thickness of the superimposed net. Further, it is preferable to complete the processing in one pass in order to minimize the processing distortion. By this roll processing, a plurality of nets are brought into close contact with each other and integrated, but in order to further strengthen this bonding, it is preferable to heat at a temperature of 1300 to 1600 ° C. for about 1 to 3 hours to reduce the strength of the bonding portion. Improve. In this case, since molybdenum rapidly oxidizes when heated in an oxidizing atmosphere, it is preferable to heat in a furnace in a non-oxidizing atmosphere, preferably a reducing atmosphere such as a hydrogen atmosphere. At the time of this heating, it is preferable to place a weight made of a block of a high melting point metal such as tungsten or molybdenum on the superimposed net and heat while applying pressure. The magnitude of the pressure may be, for example, about 20 g / cm 2 or more. By applying the above-mentioned pressurized heating, a strengthening bond can be obtained by the effect of eliminating processing strain and causing partial fusion.

m, all of which were electropolished wires. This wire is knitted (plain weave, twill weave) and is a single net (primary net) with a width of 1000 mm.
Was formed. The details were as shown in FIG. 2 (a).
The net was chemically cleaned and degreased sufficiently, and a plurality of the nets were stacked and cut to a predetermined size. The number of superposed sheets is 2 for normal use.
Although the number of sheets may be sufficient, the production is relatively easy even when, for example, about five sheets are superposed. When using a roll with a width of 600 mm in the next rolling process, the cutting dimensions are 300 mm width x 1000 mm length, and the width is 4 mm.
When a 00 mm roll was used, it was cut into a width of 200 mm and a length of 1000 mm.
圧延は、重ね合わせた厚みの1/2に仕上るようにロー

た。Pressurized heating was maintained at 1600 ° C. for 3 hours or more in a hydrogen stream. The heating temperature was changed depending on the wire diameter so that embrittlement did not occur. The weight for pressurization was a block of molybdenum and tungsten, and the weight was 10 kg for an area of 150 mm × 300 mm. Thus, a net material as shown in FIG. 2 (b) was obtained. Next, this was cut to a predetermined size and subjected to press working to produce a box-shaped firing board, which was excellent in air permeability and high-temperature strength.
