Synopsis : In the hot-rolling process of seamless steel pipe by the helical rolling mill using fixed guide shoes, there are some problems due to galling between the shoes and pipe such as (1) occurrence of outside surface defects of pipe, (2) lowering of the operation rate, and (3) a decrease in shoe life. To solve these problems, unique drive roller shoes were developed and applied to the elongator in our Medium Diameter Seamless Pipe Plant, Chita Works. As a result, production with high quality and at lower cost has been accomplished. |
