退火絲是用低碳鋼冷拔、加熱、恒溫、保溫等工藝而成的一種軟質(zhì)鐵絲產(chǎn)品。退火絲按用途不同,成分也不一樣,它含有的成分有:鐵,鈷,鎳,銅,碳,鋅,還有其他元素。將熾熱的金屬坯軋成6.5mm粗的鋼條也就是盤(pán)條,再將其放入拉絲裝置內(nèi)拉成不同直徑的線,并逐步縮小拉絲盤(pán)的孔徑,進(jìn)行冷卻、退火、涂鍍等加工工藝制成各種不同規(guī)格的鐵絲。退火絲:絲號(hào)對(duì)照表wire gauge sizeSWG(mm)BWG(mm)metric(mm)84.064.194.0093.663.76-103.253.403.50112.953.053.00122.642.772.80132.342.412.50142.032.11-151.831.831.80161.631.651.65171.421.471.40181.221.251.20191.021.071.00200.910.890.90210.810.8130.80220.710.7110.70
