矿用信号电缆是一种信号传输工具。一般信号电缆传输的信号很小，为了避免信号受到干扰，信号电缆外面有一层屏蔽层，包裹的导体的屏蔽层，一般为导电布，编织铜网或铜泊（铝），屏蔽层需要接地，外来的干扰信号可被该层导入大地，避免干扰信号进入内层导体干扰同时降低传输信号的损耗。

In order to evaluate the flame-retardant performance of wire cables, iec 60332-1, iec 60332-2 and iec 60332-3 were formulated respectively. Iec60332-1 and iec60332-2 are respectively used to evaluate the flame retardant capability of a single cable when it is laid on an incline and vertically (corresponding to GB12666.3 and GB12666.4 in China). Iec60332-3 (domestic e to gb12666.5-90) is used to evaluate the flame retardant capability of beam cable when it is vertical, compared with that of beam cable when it is vertical.

主要工艺过程为:原矿磨细与粉煤混合制团，团矿经干燥和高温还原焙烧，焙烧矿团再磨细，矿浆进行选矿(重选和磁选)分离得到镍铁合金产品。该工艺的Zui大特点是生产成本低，能耗中的85%能源由煤提供，吨矿耗煤16-18kg。而火法工艺电炉熔炼的能耗8%以上由电能提供，吨矿电耗56-6kWh，两者能耗成本差价很大，按照目前的价值计算，两者价格相差3-4倍。但是该工艺存在的问题还比较多，大江山冶炼厂虽经多次改进，工艺技术仍不够稳定，经过几十年其生产规模仍停留在年产镍1万t左右。
