Cold Rolling – Process Overview
Cold rolling takes the hot rolled product and processes it further. After hot rolling, the steel is cooled to room temperature, then passed through cold rollers at a temperature lower than its recrystallisation temperature. This rolling process is called annealing and relieves stress and leads to a higher yield strength and greater hardness.

A study on the tribological behavior of water-based
Corrugated rolling is one of the metal forming processes using corrugated rolls to machine hard-to-deform metals, which leads to problems of high friction and severe wear. Lubricants are essential to reduce rolling forces, extend the life of corrugated rolls, and improve efficiency. In this work, a comparison of the surface quality of copper plates …
How to pick the best rolling mill! – Pepetools
When annealing silver, a simple trick is to use a sharpie marker and draw a clear line on the surface of the silver. As you heat, you will reach a point where the sharpie mark disappears. Quench in water immediately. Whilst you work your material through a rolling mill, it will quickly harden again.
Rolling of magnesium alloys
Conventional rolling is the main established production method to produce thin, flat sheets as well as profiled products.
