The input into the rolling process is aluminium slab of 400-600 mm thick-ness. After pre-heating to 500°C and rolling, the exit strip thickness is in the range of 18-45 mm. This material is heated again to 400°C and then it enters into a tandem hot rolling mill (Figure 3) as strips of 20-45 mm thickness. The output thickness is typically ...
Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].
the rolling process, especially in a cold strip mill. If the thickness variation of the hot-rolled aluminum strip can be reduced, it will be possible to increase the production speed of the cold strip mill. These claims set new demands on the acceptable rolling forces and torques which, together with the roll pass design, have a significant ...

Li et al. proposed a multi-objective optimization model for draft scheduling of steel hot strip mill aiming at minimizing rolling power, rolling force ratio distribution and good strip shape. Jing et al. [ 51 ] and Che et al. [ 52 ] showed a rolling schedule model based on the slippage factor to equal power margin and prevent the slip phenomenon.

The process stability of finishing mill is significantly influenced by the clearance between the chocks and housing in mill stands. The on-site data of a finishing mill had shown that the clearances in the finishing mill stands were clearly associated with the incidence of strip end flip. The aim of this work was to establish a numerical model to analyze the effect of the clearances on the ...

The factors that significantly influence the temperature of coiled strips are the rolling rate and the amount of CM supplied to the mill stands during cold rolling. The change in the strip temperature by 50°C is equivalent to the change in the reel unit tension by about 130 N/mm 2, whereas the rated specific tension of coiled strips is 21 to ...

After passing through in-line hot rolling mills and typically undergoing 10–50% thickness reduction, 4) the hot strip passes onto a run-out table, where it is rapidly cooled by spraying water jets and is subsequently coiled. 4,10) The strips may then be uncoiled, cold-rolled, and annealed, so as to obtain more desirable microstructures and ...
Aluminum bearing alloy on the bonded bi-metal strips has internal stresses and the stress on the boundary between the aluminum and steel strip. The stresses may lead to the bearings failure therefore stress relief operation of the bonded strips is necessary. In addition to this the aluminum grains and tin plates adjacent to the grains surfaces are elongated along the Rolling direction.
