Aluzinc. Aluzinc, Aluminium and Zinc alloy Aluminium (55%), Zinc (43.4%) and Silicon (1.6%), is a cold-rolled galvanized steel. Aluzinc has excellent corrosion resistance in most atmospheric conditions, this is achieved through the combination of sacrificial protection of the zinc, and the barrier protection of the aluminium.

How Does a Cold Rolling Mill Work? The process of cold rolling a metal alloy starts with either sheet metal or strip coil. These materials are placed into large rollers, which compress it down and squeeze it under high pressure just below its ultimate tensile strength. Depending on the amount of compression, different mechanical properties and

2018-2-21 · mined by edging and rolling the strip in the roughing mill. The width deviation after the finishing mill arises from the width deviation in front of the finishing mill and from width-spread anomaly occurring inside the finish-ing mill. The behavior of width spread in a finishing mill depends on effects in roll bite and on the creep defor-mation

Rolling oils are widely used in cold rolling to improve the surface quality of the metal products and to reduce the mill power consumption and roll wear. In practice, mixed film regime prevails in the roll bite, where the film is thin and metal to metal contact occurs at the surface asperities. Simplified analytical models have been developed
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished 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 steel sheet for transport to the next process.
The sheet can whip/hit into the roll surface and mark it. As a result, the following coil produced through the hot strip mill will have these bruises on the head end. If the marks on the work rolls are light, the defect only bruises the next coils surface and eventually wears off the rolls due to friction while rolling that coil.
