なってしまう。[Problems to be Solved by the Invention] In the following two conventional devices, the metal plates I and I to be charged are
The rotational speed of the metal plate charging belt 5 is constant regardless of variations in the weight of the metal plate charging belt 5. Therefore, the metal plates 1 are charged into the metal melting furnace 6 with variations in weight, resulting in significant fluctuations in the molten metal within the metal melting furnace 6.
そして、この溶湯の変動に連動して、注湯量が不安定と
なり、これが以降の工程に影響して均一な品質の鋳造品
の生産が困難となってしまう。In conjunction with this fluctuation in the molten metal, the amount of poured metal becomes unstable, which affects subsequent steps and makes it difficult to produce cast products of uniform quality.
また、これに起因して鋳造作業上のトラブル、特に金属
溶解炉内の温度のバラツキが生じ易い。Further, due to this, troubles in casting operations, particularly temperature variations within the metal melting furnace, are likely to occur.

急落し、逆に重量の小さいものを装入すると炉内温度は
急昇してしまう。このため溶体温度が不安定になり、よ
って高品質の鋳造製品を得ることが極めて困難となる。If a heavy item is charged, the temperature inside the furnace will drop sharply, and conversely, if a light weight item is charged, the temperature inside the furnace will rise rapidly. This makes the solution temperature unstable, making it extremely difficult to obtain high quality cast products.
併せて前述の流量のバラツキと相まって不安定な温度で
