| Abstract: | The high quality heavy rail must be produced by high precision rolling technology. The conventional technology of 2-H mill adopted in our country is difficult to produced it. The universal pass is the best method of rolling high precision heavy rail. The paper studied the influence factors, such as mill size, pass number and shape, on the rail size precision and carried out the test. |
