Pilger rolling is a basic process of the seamless steel tube. The tube billet is rolled by the pass with the variable section, which gradually shrinks to reduce the diameter and wall. As shown in Figure 2, the electromagnetic induction heating device is fixed on the moving stand of the rolling mill and moves synchronously with the rollers at 1200#176;C.
pilger mill groove grinding machine manufacturers. Used Cold Pilger Mill in Good Condition. Product Introduction. This is used cold rolling machinery is three roll type, which use three 120degree of each other rollers and mandrel to form a groove to roll high precision thin wall seamless pipes and tubes.
#0183;#32;The conversion of the rolling mill to a pilger mill consisted of removing the mechanical linkages that connected the gear motors to the roll dies. The pilger mill system was designed to use indexable servo motors that are connected to the large drive rolls directly. This design allows for more flexibility in the degree and speed of die rotation.
Therefore, our cold pilger mill is suitable for processing medium or large diameter tubes. + More. LG325H Cold Pilger Mill. Tube conveying system with rolls applied in our cold pilger mill is easy to adjust and can keep the finished tubes along the rolling line. Thus,
Institute Tsvetmetobrabotka proposes to carry out modernization of roller type cold rolling tube mills CRTMR (HPTR) 815, 1530, 3080, 60120 of VNIIMETMASH and AZTM companies in order to extent technological possibilities of existing equipment, to increase the quality of rolled tubes, to decrease cost of mill equipment repair and maintenance.
The method and pilger mill of the invention are suitable for effecting maximum reduction of the billet in a single pass simultaneously over its inside diameter and across the tube wall, which makes it possible to substantially enhance the production efficiency of the mill used for rolling hardtodeform metals and alloys, as compared to the priorart pilger mills which perform rolling either with the aid of rollers or
