#0183;#32;What I claim is 1. A rolling mill stand of the type including a pair of roll frames arranged in spaced relationship, a plurality of vertically adjustable rolls, a plurality of vertically adjustable frame caps for supporting said rolls and a plurality of tie rods connected to said frames the improvement which comprises, a stationary top plate, means for connecting the upper ends of said tie
roll stand, but is guided on the roll neck by the axial bearing. Since the guidance forces are not very high, a deep groove ball bearing is fitted here. This only increases the width of the bearing arrangement to a small degree. It is advisable to use a deep groove ball bearing with the same section height as
shown that this quantity is a function of the roll radius, R, and the coefficient of friction,, between the strip and the roll by the following relationship: d max Thus, as expected, the higher the friction and the larger the roll radius, the greater the maximum possible draft becomes. Note that this situation is similar
The assembled roll pair is sent to rolling mill. Chocks and bearing inspections are carried out periodically. The function of roll shop also includes grinding of the shear blades which have become blunt during their use in the rolling mill. The modern roll shop in a rolling mill has the following facilities.
The number and arrangement of the roll stands of a rolling mill are determined by the function of the mill, the number of times the metal must pass between the rolls to produce a given section, and the assigned output. Eight types of rolling mills are distinguished on this basis. Singlestand mills include most blooming mills, slab mills, ball
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.
Section Rolling Mill. Rolling mills are facilities that carry out a series of processes including rolling the billets, blooms, slab and beam blanks extracted from the reheating furnace into the prescribed size and correcting any bending, cutting them into given lengths,
Tandem cold rolling mills are named by their stand arrangement and designed as sheet mills if they reduce hot band to sheet gauge or tin mills if they roll the same incoming material to tinplate stock. A typical five stand tandem cold rolling mill is illustrated in Figure 1. Figure 1: A typical five stand tandem cold rolling mill
Rolling Mill Control. Our system makes sure our customers roll their products with ease, ensuring minimum material stress between the stands. No matter if you have one strand or two we have the solution for controlling your mill. Impact Speed Drop Compensation.
The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened
The workroll diameter is 340 mm compared to 475 mm in a conventional UCM. When the standard UCM mill with five stands is considered, and if the rolling load is limited to the allowable values from the No. 1 stand onwards, the rolling load at the No. 5 stand will eventually exceed the maximum limit value.
#0183;#32;Conclusion 1. It is a good practice to use the principle of the threestand mill modeling developed at investigation of rolling mills with different number of the continuous stands. 2. The actual rolling mill has been quantitatively evaluated with regard to the force interaction of the electric drives at fluctuations of the rolling conditions. 3.
Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (Ibeams, angle stock, channel stock), bar stock, and rails. Most steel mills have rolling mill divisions that convert the semifinished casting products into finished products.
Single or double stand skinpass mills are placed inline at the exit of continuous annealing and continuous galvanizing lines. 6 high UCMMILLs are supplied in response to recent requirements to roll harder material, such as hard tin plate and SS, with improved strip flatness control capability.
