【考案の詳細な説明】
本考案はタングステン、モリブデン等の高融点金属の焼
結インゴットの未焼結部分である端部の再焼結装置に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for resintering an end portion, which is an unsintered portion, of a sintered ingot of a high melting point metal such as tungsten or molybdenum.
一般にタングステン、モリブデン等の高融点金属のイン
ゴットは、それらの金属粉の圧搾枠を直接抵抗体として
通電加熱により焼結されているが、焼結されたインゴッ
トの両端部は液体を吸収できる程の未焼結の１１である
。Generally, ingots of high-melting point metals such as tungsten and molybdenum are sintered by heating with electricity using the compressed frame of the metal powder as a direct resistor, but both ends of the sintered ingot have a high melting point that can absorb liquid. It is unsintered 11.
未焼結部分は鍛造加工すると割れ易く歩留が悪い。When the unsintered part is forged, it easily breaks and the yield is poor.
本考案の目的は、簡単な構成により、焼結インゴットの
端部のみを再度通電加熱し、インゴットの未焼結部分を
解消する装置を提供するものである。An object of the present invention is to provide an apparatus that has a simple configuration and heats only the end portion of the sintered ingot by applying electricity again to eliminate the unsintered portion of the ingot.
図面について実施例の詳細を説明する。The details of the embodiments will be explained with reference to the drawings.
第１図に本考案の実施例を示しているが、水冷された銅
パイプ１に高融点金属の電極２を有する銅クランプ３を
取付け、焼結された高融点金属のインゴット（４ａ又は
４ｂ）’ｔアスベストの架台６に乗せ、そのインゴット
の端部４ａを電極２に接触すると共にインゴットの端部
４ａの間に高融点金属板５を装入させることにより複数
のインゴットの端部を同時に直列に接触する。An embodiment of the present invention is shown in FIG. 1, in which a copper clamp 3 having an electrode 2 of a high melting point metal is attached to a water-cooled copper pipe 1, and a sintered high melting point metal ingot (4a or 4b) is attached. The ends of a plurality of ingots are placed on an asbestos pedestal 6, the ends 4a of the ingots are brought into contact with the electrodes 2, and the high melting point metal plate 5 is inserted between the ends 4a of the ingots, thereby simultaneously connecting the ends of a plurality of ingots in series. come into contact with.
接触力は、両水冷銅パイプをわずかに押し開くことによ
り付与される押圧力で十分である。A pressing force applied by slightly pushing open both water-cooled copper pipes is sufficient as the contact force.
このように配置したのち、銅パイプ１に電流を通じるこ
とにより電極２の接触部４ａのみが加熱され、所定時間
加熱されて再焼結は完了するが、通電中は第１図全体が
水素雰囲気下で行われることは当然である。After being arranged in this way, only the contact portion 4a of the electrode 2 is heated by passing an electric current through the copper pipe 1, and the re-sintering is completed after being heated for a predetermined time, but while the electricity is being applied, the entire area in Fig. 1 is in a hydrogen atmosphere. It is natural that this is done below.
本装置の電源は既設焼結装置をその捷＼切替えて使い、
交流０〜２０ボルト、Ｏ〜５０００アンペアを提供出来
る。The power source for this device is the existing sintering device.
It can provide AC 0-20 volts and O-5000 amperes.
再焼結されたインゴットの端部は、水等の液体を吸収せ
ず、鍛造加工での割れ折れが減少できる。The edges of the resintered ingot do not absorb liquids such as water, which reduces cracking during forging.
