摘要
采用两种管线钢材料 ,通过再结晶区和未再结晶区的五道次变形将试样厚度从 6 0 mm轧为 8mm。热轧后的试样进行水幕冷却 ,然后分别放置于 5 0 0℃和 40 0℃的加热炉中随炉冷却以模拟卷取。结果表明 。
Two pipe line steel specimens with 60 mm thickness were deformed to 8 mm thickness in five passes in either recrystallized or non recrystallized austenite regions subsequent to austenitization at 1200 ℃ After hot rolling, the specimens were spray water cooled and then furnace cooled from 500 ℃ and 400 ℃ to simulate coiling process The result shows that under the appropriate cooling process, the microstructure that contains mainly acicular ferrite could be obtained in all the two steels
