how pass line is calculated in hot rolling mill. Online optimization of pass schedules (thickness reduction schedules) that. Get Price How pass line is calculated in hot rolling millAnswers . The pass line is a line that runs parallel through the roll partings and passes through the centre of the stock area of each pass at every stand.
using an FEM model during the initial passes in a blooming mill, as a function of three different pass schedules, roll groove depth, collar taper angle and corner radius. The simulations predicted the effective strain penetration, load, torque, sh tail billet end shapes, and metal ow behaviour at a chosen temperature, mill rpm and draft.
Skin pass is another type of rolling process. Skin pass rolling is defined as a process in which fine structure give to the newly generated grain. After annealing process so that it become useful for forming operation. In case of skin rolling also known as a skin pass having less reduction around %.
Thickness measurement is one of the most important measurement tasks in hot rolling mills. With the Oframe and Cframe thicknessCONTROL MTS 820x and MTS 920x series, MicroEpsilon offers high precision measurement systems. Based on laser triangulati
Jun 18, 2014 #183; Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.
severe rolling accidents, due to faults by operators, weak rolled materials with internal defects, or because of other problems in a mill such as a power cut, mechanical problems of transportation or in the water cooling system. Problems of this kind can never really be calculated but they have a
how pass line is calculated in hot rolling mill? If your Answer is chosen as the accepted #187; Learn More. Slit rolling Danieli Corp. 2 Morg#229;rdshammar Guide Systems, a Division of Morg#229;rdshammar AB, is a world wide known producer of fine guide equipment for hot rolling mills.
Hot rolling (above recrystallization point) strain rate effect, plane strain von Mises Average strain rate = = f R b h h L V t ln amp; m 2flow = =amp; average flow stress: due
The final dimensional quality of the rolled product is determined by the rolling stands within the finishing mill. The dimensional accuracy in the final product depends on many factors including the initial stock dimensions, roll pass sequence, temperature, microstructure, roll surface quality, roll and stand stiffness and the stock/roll friction condition.
A hot rolling schedule of non With the procedure total rolling force and the distribution of rolling force per width of each pass for HC mill are calculated using The off line simulation
SKINPASS MILL Excellent Flatness and a Perfect Finish The advantages of skinpass mills (also known as temper mills) from Primetals Technologies include full compliance with tight strip elongation tolerances; excellent flatness performance; high surface quality with respect to roughness, peak count and low residuals; and the availability of wet and dry skinpassing modes.

Nov 27, 2015#183; Rolls and roll pass design. Rolls are the tools of the rolling mill and are the costliest consumable in a rolling mill. The way the rolls are used to execute their duty of deforming steel is in many cases largely determined by the roll pass design.
How pass line is calculated in hot rolling mill The pass line is a line that runs parallel through the roll partings and passes through the centre of the stock area of each pass
#0183;#32;Roll pass design in continuous bar mills 1. African Foundries Ltd. Lagos, Nigeria Presented by Rul Kishore 2. Basics of Rolling A rolling mill consist of several, at least two rolls cylindrical or nearly cylindrical bodies which are termed as roll and which rest in bearings at their ends. The normal and average center distance from the center of one roll to the
is basically the same as that for finishing mill in the hot strip mill described in, the setup calculation is executed before each pass. The crown and flatness at passes that have completed rolling are calculated using actual values, and CNP#174; roll shift positions and work roll bending forces for passes that have not completed
The pass line in a cold rolling mill passes through the center of the billet which is on the funace exit rollers and runs through each stand through the shear blades dividing the shear prior to
