摘要： An extrusion process for forming consumable anodes and the product produced therein. The process comprises the co-extrusion of a wire core having a non-ferrous light metal surface with an overcoating of a dissimilar light metal. A synthetically produced non-ferrous metal oxide layer is interposed between the dissimilar light metal surfaces to reduce the incidence of core wire breakage during extrusion operations. It is believed that alloying of the light metal core surface with the dissimilar extruded overcoating is inhibited by the oxide layer, thereby substantially eliminating adherence of a low melting, non-ferrous alloy to the extrusion die. Breakage of the core wire during extrusion is thereby minimized.
摘要翻译：用于形成消耗性阳极的挤出工艺及其中生产的产品。该方法包括将具有有色金属轻金属表面的线芯与不相似的轻金属的外涂层共挤出。在不同的轻金属表面之间插入合成生产的有色金属氧化物层，以减少挤压操作期间芯线断裂的发生。据信，轻金属芯表面与异种挤出外涂层的合金化被氧化物层抑制，从而基本上消除了低熔点非铁合金对挤出模头的粘附。因此，在挤出过程中芯线的断裂最小化。
