Z-mill - Wikipedia

Sendzimir Mills commonly carry the prefix ZR, which stands for "Zimna," the Polish word for "cold," and "reversing." This prefix was used the first time to describe Silesia's first reduction mill. The numbers, and sometimes letters, following this prefix describe the mill's geometry, the relative size of its work roll, and the widest strip that the mill can roll.

Cold Rolling - process overview - EngineeringClicks

The cold rolling mill is usually fitted with thickness gauges that check the steel as it comes out of the rollers. Reversing mills are designed so that the steel can be reversed and pushed back through the rollers which are brought closer together each time until the desired thickness is achieved. Multi-stand mills have three to six pairs of rollers in a series, each pre-set to reduce the ...

roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product. Roll Bite temperatures in slower heavily drafted stands can peak in the region of 300oC, diminishing with the reducing thickness and increasing speed in the downstream mill ...

Cold Rolled Products - ArcelorMittal

The pickled hot rolled strip is cold reduced in a cold rolling mill to the specified thickness. The critical points at this stage are flatness and precise thickness. Mittal Steel South Africa meets these criteria by using fully automated and computerised equipment. Annealing Cold rolling elongates the grains of the steel in the direction of rolling, making the steel hard and brittle. Annealing ...

Hot Rolled Steel & Cold Rolled Steel - Difference .

Therefore, cold rolled steel is identifiable by an oily and smooth surface. As the working takes place in temperatures below the rescrystallisation temperature, strain hardening occurs. The rolls induce plastic deformation. Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel ...
