摘　　要：采用盐浴炉退火处理方法,测定了两种冷轧ELC-BH钢在两种恒温条件下发生再结晶的时间,并在所测盐浴处理升温时间的基础上,根据Arrhenius公式计算了两种钢的再结晶激活能,并由此确定了其在30s、60s、90s退火时间条件下的再结晶温度。试验结果显示,硼含量是影响BH钢再结晶温度的重要因素。The recrystallization times at two different constant temperatures of two cold rolled ELC-BH steels were measured respectively by salt bath furnace annealing method. With the measured heating-up time, the recrystallization activation energies of two steels were calculated using Arrhenius formula. Consequently, the recrystallization temperatures were determined at annealing time of 30s, 60s and 90s respectively. The test results showed that B content was an important element to influence the recrystallization temperature of BH steel.
