针对82B高碳钢盘条实际生产条件及存在的问题,应用Gleeble-1500热/力模拟机测定82B高碳钢盘条动态连续冷却转变曲线,分析了终轧温度和冷却速度对盘条组织的形成、演变规律的影响。结果表明,终轧温度在950℃时,盘条轧后冷却速度<1℃/s时,有网状渗碳体沿晶界析出,6℃/s时开始生成马氏体组织;终轧温度在700℃时,形成的珠光体组织更加细小均匀,冷速直到9℃/s时才产生马氏体组织。 According to the actual production conditions and existing problems of 82B high carbon steel wire rod, the dynamic continuous cooling transformation curve of 82B high carbon steel wire rod was measured by Gleeble-1500 thermal / dynamic simulator. The effects of finishing temperature and cooling rate on the microstructure of wire rod, Formation, evolution of the law. The results show that when the finishing temperature is 950 ℃ and the cooling rate is less than 1 ℃ / s after rolling, reticular cementite is precipitated along the grain boundary and martensite begins to form at 6 ℃ / s. The finishing temperature At 700 ℃, the formation of pearlite microstructure more uniform, cooling until 9 ℃ / s martensite produced.
