我們单位由于想寻求镍鉻电热絲的代用品,机电组的全体同志在党的領导下发揮了敢想敢干的精神,成功地应用经过淬火处理的铁絲代替了镍鉻电热絲,解决了电炉絲缺乏的困难。現在我单位加热器具已絕大部分使用这种电热絲,使用一个多月来,效果十分良好。由于铁絲价格低廉,因而推广这方法,能大大节約国家財富。为此,特把制造方法簡介于下。 1.方法: 把20~#至22~#的鉄絲在铁捧上繞成象普通电阻絲一样的螺旋状。然后将它拿下来放在800—300℃淬火的馬弗炉中,煅燒15分钟左右,取出迅速投于冷水中
In order to seek substitutes for nickel-chrome electric heating wire, all our comrades of the electromechanical group played a bold and daring spirit under the leadership of the party. We successfully replaced the nickel-chromium electric heating wire with the quenched iron wire, Solve the lack of electric wire difficulties. Now my unit has been the vast majority of heating appliances use this heating wire, the use of more than a month, the effect is very good. Due to the low price of wire, so to promote this method can greatly save the country’s wealth. To this end, especially the manufacturing method is briefly below. 1. Method: The 20 ~ # to 22 ~ # reeling in the iron around the wire as the same general resistance wire spiral. Then take it down and place it in a quenched muffle furnace at 800-300 ° C and calcine it for about 15 minutes and remove it quickly into cold water
