摘　　要：为了适应长材轧制技术中无头轧制的工艺要求,短应力线轧机需具备带载压下功能。实现带载压下功能则要求压下装置具有较高的强度。通过对短应力线轧机压下装置的压下力矩、零部件承载能力、传递效率的计算和分析,得到了带载压下装置的力能参数,为带载压下技术的实现提供了理论支撑。采用该方法设计出合理的带载压下装置结构,实际应用表明效果较好。The short stress path rolling mill should be with the function of on-load pressure to meet the processes requirements of endless rolling for long products.The screw-down device should have higher strength to realize the function of on-load pressure.The force parameters was determined by the calculation and analysis of pressure force torque,bearing capacity of components and transmission efficiency of the screw-down device of short stress path rolling mill,which provided the theoretical support for the implementation of on-load pressure technology.The proper structure of the screw-down device was designed in this way exhibited satisfactory effect in actual application.
