Chat OnlineSMS group Cold pilger mills
Cold pilgering is a rolling process for metal tubes that reduces diameters and wall thicknesses. The Process. Located inside the tube is a stationary mandrel (1) which tapers in the rolling direction. This is attached to a long mandrel bar (2) which is secured in and rotated by a thrust block. Two dies (3) "form" the tubular stock in the same way that a rolling pin rolls out pastry.

The subsequent rolling operation in the high-speed tandem mill diminishes the interpass RX process while self-annealing might occur during the cooling of coiled hot rolled strip (35 36). The effect of strain mode and hot rolling parameters on the microstructure and texture evolution is summarized in Figure 4 .
Chat OnlineThe calculation of rolling forceInnoval Technology
The calculation of rolling force. When manufacturing sheet products it s important to understand the rolling force. This is because you need it to set the appropriate roll gap on the mill accounting for the stretch of the stand. The prediction of rolling force can be challenging due to the large number of inter-connected process variables
