In order to adapt the production of big diameter seamless steel pipe, the 100mm Mannesmann Piercer matched with Accu-Roll pipe mill is reformed by reselecting the bearing and reforming the roll box, so the rolling force and the life of the bearing are increased, the product's diameter is up to 159mm, thereby the needs of the process are me

Cause of water flowing into roll box, problem existing normally in high- speed wire rolling, is analyzed as well as the counter-measures.

A projection of advanced three times pouring two times compounding is used to resolve the technical problem of the low tensile strength in the compound layer and core of high chromium compound cast iron rolls.

To exploit the high performance roll is the target that the roll researchers are searching for because the quality of rolls directly affects the output and quality of the rolling material.

The characteristic of the high-speed stssl rolls is described in the article.

This paper introduces the numerical simulations of the blade rolling technology by MSC/superform of American MARC Co.

the technology of roll is the method of using the rolling way to produce the part and is alsothe important component of the advanced manufacturing technology .
