Steel is an iron and carbon alloy. Most steel mills use iron oxide, mixed with fine sand, and coal or charcoal. Coal plays a dual role in steel making: as a fuel or as a reducer. There are three stages in the process: reduction, refining and lamination.
The cold rolling mill is used to pass hot-rolled coils produced from the hot rolling mill between two rotating rolls and produce products of the desired thickness. The cold rolling process provides a more refined surface, improved mechanical properties …

RFS-4 - Hot Mill Roll Force Measurement System Step-by-step demonstration of the affordable, precise and smart RFS-4, a built-for-purpose roll force measurement system, specifically designed for use on both new and existing rolling mills.
The rolling mills are similar to that used in hot rolling. The cold rolling process has the advantage of providing close dimensional tolerance up to 0.025 mm. It also improves toughness, hardness, mechanical strength, surface finish of the material. Softer metals like tin, silver, gold, aluminum and its alloys undergo cold rolling.

The rolling of metals above the recrystallisation temperature is called hot rolling. The temperature at which new grains are formed in the metal is known as recrystallisation temperature. This temperature should not be too high; otherwise the metal will burn and become unsuitable for use.

Below is an animation sowing the cam hammer in action – Hammers like these would continue to be in use until the early 20th century where they were replaced by rolling mills, these were much more powerful and efficient at rolling sheet metal down to its desired dimensions, they rely on the brute force that can be utilized with today's ...

The Sarum iron rolling mill used a technique known, as the name implies, as iron rolling. The initial iron rolling methods used a process where an iron sheet or bar was passed through a pair of strong metal rollers. By passing through the rollers, the iron becomes much denser and has better surface features, which lead to higher quality ...

DC MOTOR WORKING PRINCIPLE: The DC motor working principle is that a current-carrying conductor experiences a mechanical force when placed in a magnetic field. This is known as the Lorentz force. And the direction of this force is given by FLEMING'S LEFT-HAND RULE. DC motor working principle is similar to the working principle of a DC generator.

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.
