Four Ways of Cold Rolling Metal

July 04, 2012 | Comments: 0 | Views: 245

Everyone knows that metal plays an important role in just about every modern industry. Look around and you will see a roofs and even entire businesses or appliances made from metal. Cold metal rolling is extremely useful in forming and moulding these metals.

Cold rolling is a metal working method that is used to reduce the thickness and size of metal. Unlike induction bending or hot rolling, this all takes place while the material is cold. This type of rolling not only shrinks the size of the material you are using, but it also makes it a lot stronger and harder as well. Each sheet or pipe is passed through two or more rollers that at room temperature. The rollers flatten this out and decrease the thickness while increasing the strength and hardness. And all of this is accomplished without losing any ductility. This means that your finished metal will not be more prone to cracking or forming fracture lines.

Cold metal rolling differs from hot rolling or induction bending due to the amount of heat that is applied to the metal product throughout the process. In cold metal rolling the metal is usually at room temperature differing from hot rolling where the temperature of the material is raised to a much higher degree. There are four basic methods for cold metal rolling, and each is used for a different function.

Skin rolling

Skin rolling is used to reduce the thickness of metal by.5 to 1%. The final product will be a smooth sheet that is more ductile than those produced with other methods.

Quarter Hard

Metal that is cold rolled using the quarter hard method can be bent or rolled back onto itself without cracking. This method can reduce the size of a metal by up to 50 percent.

Half Hard

Metal sheets or bars that undergo the half hard rolling process can only be bent to a 90 degree angle. This method can reduce its size by up to 50 percent.

Full Hard

When metal is cold rolled with the full hard process it can only be bent at to a 45 degree angle. This method can reduce the size of a metal by up to 50 percent.

Cold rolled metal usually produces smaller end products than when the same materials are hot rolled or undergo induction bending. These products can be used for various applications metals including:

· Sheet · Foil · Plate · Strip · Bars, beams, and rods

There are many different rolling processes attribute to metal working, and each one is used to accomplish different results. From ring rolling and controlled rolling to flat rolling and roll bending, these processes have been tweaked and developed since the early 18th century to assist in the creation of various metals to be used industry wide. Cold metal rolling is the preference of many since it tends to have a better surface finish and is twenty percent stronger than other methods.

Tube bending and metal bending has been one of the expertise of Benpro for more than a couple of decades now servicing clients from all over Australia. So, if you want to experience personalised service, go to and be amazed.
