SYSTEM AND METHOD FOR CONTROL OF A COPPER MELTING FURNACE |
| 摘要 |
A method and system of controlling a melting process of copper in a copper melting furnace including measuring at least one furnace parameter, wherein the at least one furnace parameter includes one or both of a furnace temperature and a furnace exhaust oxygen concentration, calculating a first rate of change of the furnace parameter over a first time period, calculating a second rate of change of the furnace parameter over a second time period at least a portion of which occurs after the first time period, comparing the first rate of change with the second rate of change, and indicating substantial completion of a process phase in the furnace when the second rate of change deviates by a predetermined threshold percentage from the first rate of change. |

1. A method of controlling a melting process of copper in a copper melting furnace, comprising:
measuring at least one furnace parameter, wherein the at least one furnace parameter includes one or both of a furnace temperature and a furnace exhaust oxygen concentration; calculating a first rate of change of the furnace parameter over a first time period; calculating a second rate of change of the furnace parameter over a second time period at least a portion of which occurs after the first time period; comparing the first rate of change with the second rate of change; and indicating substantial completion of a process phase in the furnace when the second rate of change deviates by a predetermined threshold percentage from the first rate of change. |
