NICKEL AND NICKEL ALLOY BARS We manufacture Nickel alloy bars in diameters between 6.35mm and 450mm. These can be supplied in fixed lengths or random lengths, in accordance with customer specifications and tolerances or international standards. These alloys are melted from raw materials and master alloys in accordance with our own chemical analysis specifications. Melting is performed either in an open electric furnace, or in a vacuum furnace. If required by the melt route, the alloy might then be re-melted by means of ESR or VAR technology and finally poured into the ingot mould or continuous casting apparatus. The subsequent hot forming processing of the ingots usually takes place in two stages via ingot hot-rolling and then billet hot-rolling. An alternative forging production route can also be selected, depending on the final size and condition of the bar. In this case the hot working would be performed by a forging press and also by a radial forging machine (eg. GFM), depending on final size. These hot worked black bars can then be processed into cold worked semi-finished products. For the most part, the cold working operation consists of peeling, drawing and straightening steps, combined with intermediate and/or final heat treatment processes. The finished bars could be as long as 8.5 metres and can be packed in accordance with the customer’s requirements and despatched.

镍和镍基合金棒材德镍（Deutsche Nickel)生产的镍和镍基合金棒材，直径范围从6.35毫米到450毫米。这些棒材可根据客户规范或国际标准以固定长度或随机长度供应。这些合金是按照我们自己的化学成分规范，从原材料和母合金中熔炼而成的。熔炼可在开放电炉或真空炉中进行。如果对熔炼有进一步需要，合金可通过ESR或VAR技术重新熔炼，最后倒入铸锭模或连续铸造设备中。接下来，铸锭通常通过两次热轧加工成型，先是铸锭初轧成方坯，然后是对方坯热轧。根据棒材的最终尺寸和状态，也可以选择另一种锻造生产工艺。在这种情况下，热加工将由锻压机和径向锻造机（如GFM）完成，具体取决于最终尺寸。这些热加工的黑棒可以进一步冷加工成半成品。冷加工过程主要包括剥皮、拉拔和矫直等步骤，还可能包括中间和/或最终热处理过程。成品棒材的长度可达8.5米，可根据客户要求进行包装并发货。
