高强度钢绞线用盘条复合强化生产方法
摘要：
本发明公开了一种高强度钢绞线用盘条复合强化生产方法。包括冶炼、脱氧合金化、LF钢包精炼、连铸、加热、轧制、冷却，其特征在于：脱氧合金化时配加Cr：0.20-0.35％，V：0.05-0.10％；加热时，控制出钢温度1050-1150℃，且保证头尾温度差为0-30℃；轧制过程控制精轧温度900-950℃；控制吐丝温度850-950℃，强冷至550-650℃。本方法所得产品性能稳定，产品强度达到1250-1300MPa，平均索氏体片间距为0.16-0.18μm，可用于制作2000MPa的高强度钢绞线。
摘要（英）：

The invention discloses a compound strengthening production method of high-strength steel wire rods for steel strands. The method comprises the following steps: smelting, deoxidation alloying, LF ladle refining, continuous casting, heating, rolling and cooling. The method is characterized in that 0.20-0.35% of Cr and 0.05-0.10% of V are added during deoxidation alloying; during heating, the tapping temperature is controlled to 1050-1150 DEG C, the temperature difference from the front to the end is ensured to 0-30 DEG C; the finish rolling temperature during rolling is controlled to 900-950 DEG C; the laying temperature is controlled to 850-950 DEG C, and the product is intensively cooled to 550-650 DEG C. The product obtained by the method has stable performance, the product strength is up to 1250-1300MPa, the average sorbite spacing is 0.16-0.18mu m, and the product can be used to prepare 2000MPa of high-strength steel strands.
