Metal bars are one of the most used materials in many industries, and their production is a complex process. Are you interested in learning how they are manufactured? If so, you’ve come to the right place. Below, this centerless ground bar supplier in Cleveland, Ohio is going to explain how metal bars are created through various steps that involve melting, casting, and cooling of metals.
We’ll also look at some of the different types of metal bars available in the market and what they’re used for. Finally, we’ll explore how advances in technology have changed the way these products can be produced.
Step #1: Melting the Metal
The first step in the production of metal bars is melting the metal. This latest, most-“green” process involves heating scrap and small quantities of alloys (depending on the specification) beyond its melting point and transforming it into a liquid state.
The type of metal melted depends on the purpose for which it will be used, but popular options include steel, aluminum, copper, and brass.
When melting metals, safety precautions need to be taken by the manufacturing mill that supplies your centerless ground bar supplier in Cleveland, Ohio due to the high temperatures involved.
There are several methods for melting metals — such as induction furnaces, and electric arc furnaces — that require skilled operators for successful operations.
These furnaces can hold up to 200 tons of molten material at any given time and include refractory linings made from ceramic materials to prevent damage to the furnace shell from the high temperature of the furnace.
Step #2: Molding the Metal
Once the metal has been melted, it is then poured into a mold. The mold provides shape and size to the ingot, which will depend on its intended use.
Molten metals are poured into the mold at temperatures ranging between 700°C and 2200°C, depending on the grade and once the liquid cools down to room temperature, the ingots, as they are known can be removed from their molds.
Depending on the type of metal being produced, additional post-molding treatments such as heat treating or annealing may also be necessary for further strengthening of the product.
Step #3: Rolling the Metal Bar
The third step in producing metal bars is rolling the ingot to the final bar size. This involves cogging or forging the ingot down to a smaller diameter to improve internal cohesiveness, then processing through a set of rolls to gradually reduce the size of the bar to its finished size.
If necessary, your centerless ground bar supplier in Cleveland, Ohio may request additional processing such as heat treating to achieve the specific mechanical properties required for the project.
Once cooled down, the bar can be inspected for quality control to ensure full adherence to specification.
How Are Centerless Ground Bars Made?
Centerless ground bars are produced through a process known as centerless grinding. This involves passing the hot rolled bar between two rotating grinding wheels, with the workpiece held in place by an adjustable guide rail.
The result is a metal bar that has been precisely measured and is uniform in size and shape.
The surface of these metal bars can also be further refined through polishing or buffing processes to give them extra shine and tighter tolerances. In addition to its aesthetic qualities, centerless ground bars generally have higher mechanical properties compared to non-ground metal bars.
