Cold rolling mill – A mill that reduces the cross sectional area of the metal by rolling at approximately room temperature. Cold strip mill – A mill that rolls strip without first reheating. Cold work – Plastic deformation at such temperatures and rates that substantial increases occur in the strength and hardness of the metal.

Cold rolling is a process that occurs after hot rolling in order to reduce the thickness, increase the yield and tensile strength and pliability of metal. It is a relatively expensive and labour-intensive process, but the improved mechanical properties increase the value of the finished product, whether that is a sheet, strip, or coil.

LPBFed parts tend to exhibit much finer structures due to their much higher cooling rates (typically 10 6 –10 8 K/s ) than LDED (typically 10 3 –10 5 K/s ). These phenomena could be observed from microstructures taken from the horizontal and vertical cross-sections of the LPBF and LDED fabricated C300 MS specimens, as illustrated in Fig. 8 .

It consists in flattening a strip (width L) between two flat, parallel anvils (width 2 a ). From the measurements of force F and final thickness 2 h (initial thickness 2 h0 ), the friction factor m can be easily deduced: (1) F=2aL 2σ 0 ( ε. ̄. ) 3 1+m a 4h where σ0 is the yield stress. The friction stress is τ=mσ 0 / 3.

A strip mill is a type of steel mill invented in the early 1900s. Strip mills and their new technology produced larger sheets of steel at lower costs, revolutionizing the industry and the future of steel. With increased production at lower costs, steel and tin could be used for many more products. There are several types of strip mills that ...

Modelling of a rolling process can be performed for a variety of goals. Early SM-based strip rolling models [1, 2] were in search of roll loads and torques to dimension stands and set up the roll gap; later on, the UBM [], then the FEM [4–6] were used to study "spread", i.e. hot rolled slab widening and edge shape in view of optimized pass design.
