Gas Atomization Slow Motion
Gas Atomization of nickel alloys for metal powder production from our VersaMelt Multi Melting Mode Inert Gas Atomiser. This shows a slow motion disruption in a free fall jet (or die) of the metal stream/droplets. Full credit to NCSU for sharing this footage! The powder produced will go into additive manufacturing or other powder metallurgy. The base atomizer has induction melting capacity and plasma arc melting capacities, so most any metal can be melted and atomized. Recently it has bee used for super alloys, RHEA and HEA powder research.

Strip Casting Small Furnace
มุมมอง 1913 หลายเดือนก่อน
This is small batch strip casting for magnetic materials/metals. Known as strip casting or melt spinning, this is the method used for rapidly quenching materials/alloys for magnetic or other properties. In this video it was the first test run with this furnace. Visit us at www.arcastinc.com if you want to learn more about strip casting, melt spinning, arc melting, gas atomizing or cold crucible...
Gas Atomization by Arcast Inc for Metal Powder Production
มุมมอง 53310 หลายเดือนก่อน
This is an example of an gas atomizing of metal powder for 3D printing or other powder metallurgy applicaiotns. Gas atomising is the way most metal powder is produced for addative manuafacturing.

Plasma Arc Melting with Stirring
มุมมอง 8K4 ปีที่แล้ว
This is cold crucible arc melting with electromagnetic stirring. This shows melting with and without stirring current. You can clearly see the stirring in action, you can see the melt open up and expose the bottom of the crucible. You can clearly see rigorous stirring as the arc is moved around mixing all the material without the need to flip and remelt like you would see in conventional arc me...
CEIT's Inert Gas Atomizer

Close-Coupled Inert Gas Atomizer, with 30-250 kg capacity. This is a steel atomizing run with argon. Visit Arcast Inc. for more information, www.arcastinc.com .
Arc 200 Atomization of titanium.
มุมมอง 9464 ปีที่แล้ว
Arc Melting and Atomization. This is Arcast's Arc 200 model with gas atomizer option. The metal being atomized is titanium to form metal powder. The process involves melting metal with an arc and a specially designed gas jet pulls this metal into a high velocity argon jet that breaks the metal into very small droplets and forms metal powder for 3D printing or AM.
Melt Spinner
มุมมอง 2.5K5 ปีที่แล้ว
This is a short video showing the Arcast Inc. melt spinner product. The process is fast and only takes a few seconds once the metal is fully molten. The metal is ejected onto a spinning water cooled copper wheel. The purpose is to rapidly quench the alloy to achieve advanced properties and structures. Often this material is crushed into powder and reformed and sintered into the final shape. Thi...
Free Fall Atomization Arc/Plasma Melting
มุมมอง 1.1K5 ปีที่แล้ว
Tube feed, arc/plasma melting, inert gas atomization of recycled titanium machine chip. This is just the start of the process. Arcast has developed an advanced way to process a semi-continuous feed of various feed-stocks. This method can be used for any metal and most any form. It produces high quality spherical metal powder for 3D printing or additive manufacturing. This is one of many melting...

Which type torch you can explain torch model
The torch type is a DC transfer arc. A bit like in TIG welding.
Could you cast me a iridium ring if I provide the metal I would like 2 •30 gram rings
It might be possible. The melting point is very high and it would freeze very quickly. The quality of the casting may not be very good. It may be better to melt it into a ring shaped crucible.
This work is taking place at the Royce Translational Centre at the University of Sheffield. Dr Rob Deffley is the expert running the process in this video.
Can Quartz / Silica be purified using these furnaces in the process of production of High Purity Quartz?
It may be possible. We have melted glass/oxides in these furnaces.
Which material is the crucible made of?
It is made from copper and water cooled.
do you need a degree to work doing this?
It depends on the organisation, but no it should not be necessary.
I am a melter and do this process for a living. I always find it cool to see the atomization from the tower.
Would that work with Iridium or even tungsten? Could those metals be cast into a mold ?
Yes, the stirring works for these materials. Casting is difficult because of how quickly these materials freeze. But, in some cases it can be done.
may know the what type of mechanism used for electrode revolving and moving down
This uses a batch melt in a ceramic crucible. The bar/rod feeder type simply uses a rotating chuck mounted on lead screws and uses vacuum feedthroughs for seals.
@@Arcast123 thank for your valuable replay And i have one doubt can i get experimental values??
What type of gases are used for these plasma torches. Can these gases be customized. What is the atmosphere inside the furnace (vacuum?)?
Normally argon is used, but helium is also an option. Some gas is needed to ionize. It should be inert to prevent reactions with the electrode. The chamber is evacuated first to a high vacuum standard, then backfilled with some gas.
@@Arcast123 thanks for your response. What are the capacities of these arc furnaces that you make?
@@maniranjan7948 we make furnaces that melt 10s of grams up to 100s of kilograms. All metals can be melted.
Can one use arc melting + electromagnetic stirring to mix filler material into the melt? It works with mechanical melt stirring, but the method shown here seems to be able to handle smaller batch sizes.
It is possible. It depends on the material?
Hello ! What is the base metal that the plasma torch is making the puddle on ?
In this case it is titanium.
@@Arcast123 Will the plasma puddle stick to the titanium base ? Thxs
@@firefox2716 the molten titanium is held in a water cooled copper crucible, so it doesn't stick or react in any way. This is one of the only ways to hold molten titanium.
@@Arcast123 Thanks , that's pretty amazing ! I was trying to locate a plasma smelter that melts copper metals ! I seen the Electric arc rod smelters, but I know the plasma is different . Happy Thanksgiving

How many amp use, can you provide torch brand name
The amperage can be 50-2400 amps in our products. It is a DC transfer arc type.
Excellent!!!!!!!
Excellent Operations
Thank you for your VIDEO.
Can you please give me your contact details. Do you sell furnaces for gas atomizer?
Yes we do. You can find our details and some product info at www.arcastinc.com
Sorry I didn't see this comment before. Please visit www.arcastinc.com
These melting furnaces are incredible fun to run!
Does it work on tungsten
Yes, most any metl can be melted in this way.
Is that a supersonic nozzle?
It has the potential to be supersonic, but we have not confirmed this with any measurements. The gas pressures ranges from 500 psi to 1500 psi. We use a wide range of gas jets/dies for atomization. They all have different applications and benefits. This type is considered a free-fall type and this relates to the melt delivery. The two common types are close-coupled and free-fall but there are other ways of doing this work. I hope this helps! It is hard to know how to reply if you do not know the questioner's back ground.
Wonderful video and melting.
it is very inter esting and first lol
