Hot Metal vs Forged - What's the Difference?

Hot metal is a type of steel that was developed during the late 19th century in conjunction with the development of pig iron making techniques

When pig iron is melted, it becomes molten and a great deal of energy is required to keep it at this temperature. To do this, hot-working furnaces were developed that could melt pig iron castings in order to forge them into wrought iron. These open-hearth furnaces allowed the molten metal to be heated by hot air through jets or by hot coke or coal dust being blown on top of the molten metal. This process allowed for much more control over the temperature of the molten metal and consequently made possible much higher quality finished products than those produced by traditional methods.

What is Forging Service

Metal forging is a manufacturing process in which metal is heated and placed under pressure to produce parts with a desired shape. Forging can be done using a variety of tools and machines, such as hammers and presses, to shape the metal into the desired shape. The process of forging can produce parts that are stronger and more durable than those made using other manufacturing methods. Many different metals, including steel, aluminum, and brass, can be forged using this process.

How Does Forging Service Work

Once we open the die/mold of forging process and get ready, then we start forging mass production.

The processes of forging are as below:

1/ The metal is heated to a high temperature in a forge or furnace. The heated metal is placed on an anvil or forging die.

2/ The metal is struck with a hammer or press to shape it into the desired form.

3/ The metal may be reheated and reshaped multiple times to achieve the desired shape and properties.

4/ The metal is cooled and hardened by quenching it in water or oil.

The forged metal parts normally need further processed by machining, heat treatment, or other methods to achieve the final desired properties and finish.
