Metal melting apparatus |
| 摘要 |
A refractory well (16) for melting scrap metal pieces into a molten metal bath, comprises an inlet (18) for introducing metal into said well, the inlet being located so as to cause a circular flow of molten metal in said well, an outlet (19) for the flow of metal from said well and an electromagnetic pump (22) located beneath the refractory well for pumping said molten metal from said well through said outlet. |

1. A refractory well for melting solid scrap metal pieces into a molten metal bath, comprising:
an inlet for introducing the molten metal into said refractory well from the molten metal bath, said inlet being located so as to cause a circular flow of the molten metal in said refractory well; an outlet for the flow of the molten metal from said refractory well; an electromagnetic pump located beneath the refractory well for pumping said molten metal from said refractory well through said outlet; and a bypass conducting a portion of the molten metal past said outlet, said bypass being arranged so as to enable heat transfer from the molten metal in said bypass to said refractory well at or adjacent said outlet thereby to minimize the risk of blockage of solid metal scraps in said outlet, the refractory well defining a cavity. |
