随着我国减排政策的加强落实,各地方城市规划和环保工作的快速发展,以前承建的高能耗、污染大、产能低的小型铝电解槽逐步改建为300 kA以上大型铝电解槽。大型铝电解槽是高产值、低能耗、环保型的先进冶炼设备,但是这种大型铝电解熔炼面积较大、电流强度和电磁场较高、下料和打壳点多等特点,铝电解槽投产运行后要全面考虑后期有可能发生的应急事件、预定有效地解救方案、预制简易快捷的应急备件。一旦发生应急事件后悔莫及、损失极大,严重的使系列断电瘫痪。
With the implementation of China’s emission reduction policies and the rapid development of urban planning and environmental protection in various localities, the small-scale aluminum reduction cells previously constructed with high energy consumption, high pollution and low production capacity have been gradually converted into large-scale aluminum reduction cells above 300 kA. The large-scale aluminum electrolytic cell is an advanced smelting equipment with high output, low energy consumption and environment-friendly. However, this large-sized aluminum electrolytic smelting area is large, the current intensity and electromagnetic field are high, After the operation, it is necessary to fully consider the emergency events that may occur in the later period, and plan to effectively rescue the plan and prefabricate quick and easy emergency spare parts. In the event of emergency regret, the great loss, serious paralysis of the series off.
