Advantages Of Forged Glass Coating And Seamless Ring Rolling Forging Technique In Manufacturing Of Many Necessary Units Like Autos, Transport And Other


Metals, in industries, like manufacturing, construction, aircraft and automotive play an important role. A highly ductile form of metal is required by these sectors for manufacturing of various necessary units like cars, transportation and any other significant units. For this reason, forging has become a critical process in extrusion of metals.

Forging is a method which is done for forming or molding of metals. It is done through many techniques which are different for different metals and are used according to their temperature. Various lubricants are used for carrying out this process and commonest of them are MoS2, graphite, synthetics, and glass. Glass lubricants for forging method are used as they are very brittle even at higher temperatures. Thus, because of this these glass lubricants are used in hot forging method which is done at a temperature of 1300 degrees Celsius and is later decreased to 750 degrees Celsius.

Throughout this process, a forged glass coating is formed over metals which are water based and lead free. This glass coating is inculcated with high lubrication and heat insulation properties. So, they are used for forging of some certain alloys of metals like titanium, stainless steel, tungsten, and nickel. A few of the benefits that make this process critical as a forging lubricant for aircraft industry are as follows:

- This process prevents oxidization of metals that has undergone forged technique. So, it aids the structures made from these metals to remain in its original shape and prevents their reaction with oxygen.

- This is an excellent lubricant as it takes the form of plastic at higher temperatures.

- Most significantly forged glass is the only lubricant that can bear so much high temperature without losing its technical characteristics.

A general forging technique used in aerospace industry is seamless ring rolling forging. In this technique a hole is punched in thick, piece of metal which creates its shape like a donut. After this these pieces are drawn under rolling & squeezing process into a ring. The diameter of ring differs according to the quantity of metal to be forged.

These seamless rings rollers can be either flat or cylindrical in shape. The height of these configurations varies between 0.5 inches to 9 feet. All this depends on the instruments used and based on it wall thickness and height are proportioned. The ordinary proportion range is 1:16 at the base and 16:1 at the top, but this can vary in case of special processing's.

Forging technique is important for increasing ductility and tangential strength of metals that make them suitable for components that are resistant to pressure like engines for aircrafts, couplings, gears, rotor pacers, cases and sealed discs, pressure vessels, wheel bearings, valve bodies and flanges.
