钢管连铸连轧工艺的实验研究

在 Gleeble－ 1500热模拟实验机上模拟连铸坯直轧、热装热送轧制和冷装再加热轧制 3种工艺制度下 32Mn6钢连铸坯的穿孔过程，分析在不同工艺下压缩试样的组织和力学性能，比较不同工艺对组织和性能的影响，探索采用连铸坯直轧和热装轧制钢管的可能性。

Experimental research on process of continuous rolling of steel tubes from continuously cast billets

： The processes of piercing 32Mn6 steel CC billet under the three technological schedules i. e. on－ line pipe－ rolling with hot CC billets, off－ line pipe－ rolling with hot－ charged＆ hot－ transferred CC billets and off－ line pipe－ rolling with cold－ charged＆ reheated CC billets were simulated with the Gleeble－ 1500 thermal simulator to investigate the structural and mechanical properties of the compressed samples under the said different technological schedules, the structural properties VS the said schedules and the feasibility for on－ line pipe－ rolling with hot－ CC billets and off－ line pipe－ rolling with hot－ charged CC billets.
