上海第五钢铁厂—炼钢厂在电炉短网导线的供导电接触处涂敷一种接触导电膏,不但可以代替原来使用的镀银、镀锡工艺,而且节电效果好。使用这种新型导电膏后,电炉短网电阻降低0.02Ω,导致额定电流下,减少有功功率损耗约5.4kW,而在短路电流时有功功率减少更多,经统计,吨钢约减 Shanghai Fifth Steel Works - Steel Works in the short-circuit wire for electric contacts coated conductive contact with a conductive paste, not only can replace the original use of silver, tin plating process, and energy-saving effect. After using this new type of conductive paste, the short-circuit resistance of the electric furnace is reduced by 0.02Ω, resulting in a reduction of active power loss of about 5.4kW at rated current and more reduction of active power in short-circuit current. According to statistics,
