Designing a plate mill is far more than an exercise in mechanical engineering. It is a special and unique example of combining operational efficiency and metallurgical function. Plate products derive their properties from the deformation and temperature path they follow, and this means that the flexibility to roll a broad mix in a single mill must be built into the layout and the machine parameters.
A method for modeling of the work roll contour in a four high mill is presented in Paper B. The active parameters were found to be the plate length and the variations of the pressure from the plate and the back-up roll on the work roll along the work roll barrel. The method is build up with statistical methods.
To match every technical requirement and budget, liners and wear plates are available in compound (clad) steel, solid alloy tool steel, and solid surface hardened steel. ASKO also offers plate mill levelling rolls, back-up rolls, and bearings through its partner BSA S.R.L. and furnace rolls through its

Online-Adaptation of model parameters for model based control; Description. In heavy plate rolling, the heated plates are plastically deformed by rolling mills. For this task, reversing four-high mill stands consisting of two work-rolls and two backup-rolls are often used. The plate is deformed between the two work-rolls in several rolling passes.
Plate Size: ~7" L x 2" W Plate Thickness: ~2.5mm The plate may be slightly curved when it arrives, and that’s okay! It will not harm your rolling mill, as the plates will curve with use anyway. The metal used for the plate is softer than the rolls of a rolling mill and will not damage them. It
