The electrode 1 is made of tungsten and is fixed to a support tool 8, and the support tool 8 is fixed to a positioning device 9. The electrode 1 is adjusted up and down and back and forth by a positioning device 9 via a support 8.

前記した溶解装置では、溶解時、回転軸を介して大電流を流すため、回転軸が 損傷して、るつぼ受けの寿命を短くするという問題がある。また、るつぼ受けの 側面と底部が一体構造となっているため、溶解時のるつぼの強熱によって、るつ ぼ受けが膨張し、変形して、正常な溶解ができなくなるという問題がある。さら に溶湯を湯口に注入する際のるつぼ受けの回転が自重によるもので、傾斜速度が おそく注入までに長時間を要する。また、るつぼ受けが回転止めまで回転したと き、回転止めに当たった衝撃で、るつぼ受けが撥ね、溶湯が飛び散って安定した 注入ができないという問題がある。 In the above-mentioned melting apparatus, a large current is passed through the rotating shaft during melting, so that the rotating shaft is damaged and the life of the crucible receiver is shortened. Further, since the side surface and the bottom portion of the crucible tray are integrated, there is a problem that the crucible tray expands and deforms due to strong heat of the crucible at the time of melting, and normal melting cannot be performed. In addition, the rotation of the crucible holder when pouring the molten metal into the sprue is due to its own weight, and it takes a long time until the pouring is slow. In addition, when the crucible holder rotates to the rotation stopper, the impact of the rotation stopper causes the crucible holder to repel, causing the molten metal to scatter and prevent stable injection.
【０００８】 本考案は、上記の問題点を解決するためになされたもので、溶解電流を広い面 を介してるつぼ受けに流すとともに、るつぼ受けの前面に開口部を、底部にスリ ットを設け、さらにるつぼ受けをばねで付勢し、回転止めに磁石を設けることに よって、るつぼ受けの寿命を延ばし、安定した溶解と注入ができる高融点金属の 溶解装置を提供することを目的とする。The present invention has been made in order to solve the above-mentioned problems, and a melting current is caused to flow through a wide surface to a crucible receiver, and an opening is formed on the front surface of the crucible holder and a slit is formed on the bottom. It is an object of the present invention to provide a melting point of a high melting point metal, which can extend the life of the crucible holder and can perform stable melting and pouring by providing the crucible holder with a spring and urging the crucible holder with a magnet. ..
