Редукционно-растяжной стан горячей прокатки труб в линии горизонтального гидравлического пресса

Abstract

Considered technological version of the direct combination of compression and reduction rolling tube to almost final size at which the pipe is subjected to intensive cooling. This option involves rolling extrusion heat. This eliminates all the known shortcomings of traditional technology. Hot rolling reduces the energy consumption for plasticdeformation. The continuous reduction rolling press in lines align the performance of these processes. After pressing the chemical treatment is required to remove oxides. Eliminates the need for an intermediate heat treatment. Proposed to use the hydraulic roll reducing mill, and introduced the concept of automatic speed coordination pressing and rolling.
