Building a stainless steel product from the ground up involves a lot of work, technology and science. Even though there are billions of users of stainless steel items around the world, there are very few people (relatively) who know what goes into making a stainless steel product from scratch. The manufacturing process of a stainless steel product is indeed fascinating and it gives you an insight into how far our ability to craft materials has evolved since the early days of the Industrial Revolution. Here are the six most important steps in the manufacturing process of a stainless steel product:

 

1) Material handling

Uncoiler-A material handling machine located at the beginning of a process line used to hold and safely pay off or uncoil the steel strip. It controls the speed and direction of the strip of metal as it unwinds from the coil and is sent to the line for processing, such as slitting or tube mill entry.

 

2) Forming

Deep drawing press- In the second stage, the semi-finished steel shapes undergo a series of forming operations. For instance, the stainless steel is hot rolled (heated and passed through enormous rolls). The blooms and billets mentioned above are converted to bar and wire. The slabs on the other hand are formed into plates, strips or sheets. It is very common to turn semi-finished steel shapes into bars, as it is the most versatile stainless steel form. The reason why it is versatile is because it comes in all grades and sizes. You have round, squared, octagonal and hexagonal bars, each suitable for a different type of application.

 

3) Heat Treatment

Annealinf furnaces- Up next we have the heat treatment. As the name clearly suggests, the various stainless steel forms undergo a thorough annealing process during this step. Annealing is another name for heat treatment where the stainless steel is heated and cooled in a controlled environment. The purpose of this heat treatment is to relieve the pent up stress inside the stainless steel and soften the material to make it more suitable for a wide variety of applications. The people in charge of carrying out the annealing process have to be very careful about control the conditions as even the slightest of changes in the temperature, pressure, duration or cooling rate could result in a faulty product.

 

4) Descaling

Pickling- During the annealing process, a certain amount of scale appears on the surface of the stainless steel. This scale can be removed using a number of different processes that are collectively known as descaling. Pickling is one of the more common methods of carrying out the descaling process.

 

5) Cutting and Punching

The semi-finished, heat treated and descaled stainless steel forms are cut into specific shapes in this step. Mechanical cutting is performed with the aid of guillotine knives, blanking, nibbling and high speed blades. And in this step, the tap hole and the over flow will be made.

 

6) Finishing and Polishing

Polishing machine- Finishing is applied to help the stainless steel product achieve its signature aesthetically appealing appearance. Finishes are also needed to make the stainless steel product smooth and easier to clean, which is a top requirement in sanitary applications.

What is plasma cutting?
EDAWELD CO.,LTD

Plasma cutting uses a plasma torch to cut metals of various thicknesses. The Plasma Cutter blows compressed air out of a nozzle at high speed and at the same time forms an electrical arc between the nozzle and the metal to be cut. The resulting plasma is hot enough to melt the metal and the speed ensures that the molten metal is blown away from the cut.

What is plasma?

To properly explain how a plasma cutter works, we must begin by answering the basic question [What is plasma?  In its simplest terms, plasma is the fourth state of matter.  We commonly think of matter having three states: a solid, a liquid, and a gas.  Matter changes from one state to the other through the introduction of energy, such as heat.  For example, water will change from a solid (ice) to its liquid state when a certain amount of heat is applied.  If the heat levels are increased, it will change again from a liquid to a gas (steam).  Now, if the heat levels increase again, the gases that make up the steam will become ionized and electrically conductive, becoming plasma.  A plasma cutter will use this electrically conductive gas to transfer energy from a power supply to any conductive material, resulting in a cleaner, faster cutting process than with oxyfuel. 

The plasma arc formation begins when a gas such as oxygen, nitrogen, argon, or even shop air is forced through a small nozzle orifice inside the torch.  An electric arc generated from the external power supply is then introduced to this high pressured gas flow, resulting in what is commonly referred to as a [plasma jet".  The plasma jet immediately reaches temperatures up to 40,000° F, quickly piercing through the work piece and blowing away the molten material. 

Plasma system components

Power supply -- The plasma power supply converts single or three phase AC line voltage into a smooth, constant DC voltage ranging from 200 to 400VDC.   This DC voltage is responsible for maintaining the plasma arc throughout the cut.  It also regulates the current output required based on the material type and thickness being processed.
Arc Starting Console – The ASC circuit produces an AC voltage of approximately 5,000 VAC at 2 MHz which produces the spark inside of the plasma torch to create the plasma arc.
Plasma torch – The function of the plasma torch is to provide proper alignment and cooling of the consumables.  The main consumable parts required for plasma arc generation are the electrode, swirl ring, and nozzle.  An additional shielding cap may be used to further improve cut quality, and all the parts are held together by inner and outer retaining caps.
