【Abstract】 High-carbon steel wires were fog-cooling patented using low concentration polymer (CMC、PVA) aqueous solution by means of atomization system. The effect of polymer on the cooling behaviours upon fog-cooling patenting was analysed according to cooling curves and characteristic curves measured. Thereby, the approach to non-lead-patenting for high-carbon steel wires is further exploited. Experimental results show that the controlled fog-cooling patenting with polymer aqueous solution have the advantage over pure water fog-cooling patenting in cooling charateristics, and the microstructure and mechanical properties of high-carbon steel wires patented with polymer aqueous solution come up to those of lead patented steel wires.更多还原
