摘要
根据冷轧高强度低合金钢HC420LA的产品要求对其冷轧连续退火工艺进行了研究。HC420LA钢产品成分采用Nb、Ti微合金化成分体系、生产工艺选择热连轧+冷轧连续退火的工艺路线。通过实验室再结晶温度试验测定了HC420LA钢产品的再结晶温度,在工业化试生产阶段对连续退火工艺进行了试验研究,得出冷轧低合金高强钢HC420LA的再结晶温度为700℃,工业化生产时最佳加热均热温度为760℃。
Continuous annealing process of cold rolled high strength low alloy( HSLA) HC420 LA steel was studied according to the production requirements.The composition of HC420 LA steel product adopted Nb and Ti microalloying composition system.The hot rolled and cold rolled continuous annealing process were selected as the production process.The recrystallization temperature of HC420 LA steel product was determined by laboratory recrystallization temperature test.The continuous annealing process was studied in the industrial trial production stage.It is concluded that the recrystallization temperature of the cold-rolled HSLA HC420 LA steel is 700 ℃ and the optimum heating soaking temperature in industrial production is 760 ℃ .
