本发明公开了一种可有效改善钢轨矫直盲区的新型钢轨矫直机，避免将矫直盲区切除造成生产浪费。
The invention discloses a novel rail-straightening machine capable of effectively improving a straightening dead zone of a rail, and avoids waste caused by cutting off the straightening dead zone.
测定了矫直前后钢轨外形尺寸变化(包括轨头宽度、轨高、钢轨长度)，分析了轨高减少的原因。
The contour size changes of rail before and after straightening, involving width of rail head, rail height and rail length, were measured. The causes of rail height decrease were analyzed.
本发明公开了一种可减小钢轨弯曲度的热轧钢轨的空冷堆垛方法，保证矫直后钢轨的平直度达到标准的要求。
The invention discloses a hot-rolled steel air cooling and stacking method capable of reducing bending of a rail to ensure straightness of the straightened rail to meet standard requirement.
同时，钢轨的矫前弯曲度还影响矫直力的大小，进而影响矫直机的寿命。
Simultaneously, the curvature before straightening also affects the size of force on straightening, and it also affects the life span of straightening machine deeply.
