Q460D钢板轧制工艺研究
Rolling Process of Q460D Steel Plate
摘要
Abstract
The production processes of different kinds of Q460D medium and heavy plate produced were studied by controlled cooling rolling process. The results show that the first stage is rolling in the austenite recrystallization zone, and the temperature of the billet is 1 050～1 100 ℃, and the reduction rate is more than 10％. The second stage is rolling in austenite non-recrystallization, and the rolling temperature is less than or equal to 950 ℃, the finishing temperature is 860～790 ℃, until the temperature after the cumulative reduction ratio is more than 50％, more than 12％ times the rate of deformation. The laminar cooling is used, the steel will exhibit a good toughness.关键词
