What are the Differences Between Hot and Cold Metal Rolling?

The modern world relies heavily on all kinds of metalwork, with metal rolling being one of the most important manufacturing processes. At one point during the manufacturing process, all metal products are subject to this unique rolling technique, which is the first of many steps required to create a raw metal form. Reducing thickness is the aim, and the entire rolling process will be classified based on the metal’s temperature.

Sheets produced with rolling mills will start off as a bloom or slab, which will then be used with heavy applications in all kinds of industries, such as aeroplane fuselages, household appliances and car bodies. Before you call on a team of professionals to assist you, it’s a good idea to familiarise yourself with the differences between hot and cold metal rolling.

The Basics of Hot Metal Rolling

Iron and steel are the two types of metal most commonly used for both metal rolling processes. A hot strip mill is used for hot rolling, and this mill will roll slabs weighing up to 30 tons. Heated near melting point, the metal will be transported away from the mill with a coil handling system, before being loaded into the correct areas.

The Basics of Cold Metal Rolling

Before metal is rolled, slabs will be assigned to particular orders and placed individually on a roll line. Once the weight and dimensions are confirmed, the metal will be compressed. This will result in a smooth surface, and the level of strain will be dependent on the type of metal and its overall strength/hardness. Full hard, half hard, quarter hard and skin-rolled are a few examples of the cold metal rolling conditions you can choose from.

The Qualities of a Good Company

Modern rolling practises must be followed by the company you work with, and all machinery should be up-to-date. Aside from this, you must request to see the licenses and qualifications of staff members to make sure all work is completed to a satisfactory standard. Does the company have a positive list of client testimonials? Have they been in business for 10 years or more? Have big name companies collaborated with them in the past? These are just some questions you ought to ask before signing contracts.
