摘要
研究了加热温度和冷却速度对高碳钢正火钢丝的显微组织和力学性能的影响。通过大量实验室研究和生产试验证实，若提高正火时的冷速，采用水浴和铜冷正火，可使高碳钢丝的正火加热温度降至820℃左右。年产3000t的钢绳厂，采用低温正火新工艺，每年可节电40万kw·h以上。
The effect of heating temperature and cooling speed on the micro-structure and mechanics characteristics of high-carbon-steel wire normalized was studied in this paper. A number of lah studies and production trials proved that using water bath and copper c(x,ling to increase the cooli11g speed of nomalization could make the heating lemperature of high-carbon-stee1 wire droping to about 820℃The 4. 0 mi lion kwh of power could be saved yearly at steel rope plant. 3000 tons of annual output,applied by the new low temperature nomalization technology.
