Hi, Thank you for sharing experiance :). I have same termometer, that have problem laser pointer. 10 cm rise up where you want to see heating. Pointer showing wrong place :)

Thanks for the video. You probably know by now that it's not a good idea to put enameled copper wire into the crucible, since the varnish is quite flammable. Also, just FYI, the cooling fan appears to be sucking a lot of heat (and fire") right down onto the board. I'd suggest putting some sort of divider between the work coil and the pcboard. This the first time I have seen one of these 4000 watt zvs induction heaters demonstrated and it sure looks like a powerful beast! How hot did your cooling water get during this melt?

Hey! I knew it would catch fire as I did it with my propane melts but wasn't thinking about the suction power of that fan! I have since put one of my light fire bricks on the tubing as a wall which keeps heat and flame away. You can put your hand close to the crucible when it's fully heated, as long as there is no flame. I don't remember the temperature but it was pretty warm when finished, not hot but getting there. I only had about 2.5 litres of very cold water and added another 1.5 litres of very cold water about half way through. I would say about 8 litres cold water would do for a 15 minute melt without the need for checking it constantly. I've since bought a larger container for that at.....the Dollar Store!

Great video! not bad 11minutes to melt few kilos copper impressive inverter. However My Thyristor also 4000watts operating on high voltage 300VDC/12Amps takes 5 mins to melt similar load. Nevertheless Thank you for this video it helps me compare performances.

can the copper tubing be extended so its not so close to the electronics?
@shivercanada
6 ай бұрын
Yes I did that with another tube I made very slightly smaller. It doesn’t affect the electronics because of that giant fan which blows a lot of air and cools well. Making a tube too small will blow the unit as the seller explained. This is why the zero load type heaters are superior.

Have you noticed any degradation of the graphite crucible yet? Most of us feel that they last for about 10 "heats" before getting too thin to be safe.

Thanks for watching! After about 4 melts it seems to be thinning a bit, mainly the Ceramic but there is always some graphite powder after cooling. It's hard to find these ceramic lined crucibles at decent prices I might get some Ceramic fibre blanket and fit a graphite crucible inside it as a test later. cheers!

If it was steel or a ferrous metal it would heat both up but with copper the Crucible is doing the heating. This is why the water cooled copper tube doesn't itself melt. thanks for stoping by!

great video thanks, using this induction heating method could you tell if the carbon crucible was the source of heat or the copper or both? I need to use a non-carbon crucible and was curious if the induction would work on the copper only. Perhaps slower heating rate?
@shivercanada

Only if the crucible has ferrous elements in it, then the crucible will heat up the copper. The crucible will need a buffer like a ceramic blanket between the copper coil of the heater and crucible. Also “starlight” crucibles won’t work and porcelain will crack in an induction heater

Does the crucible heat up on it's own without anything in it? How is the coating on the copper coil holding up?
@shivercanada
3 жыл бұрын
I haven't tried that but I'm 99% sure it would heat up since it'e the Graphite itself that interacts with the magnetic field. This is why you can melt any metal in it, even non magnetic metals. It's still holding up, copper tubing hasn't warped or anything, the cold water is absolutely necessary...though the ceramic coated graphite crucible helps contain most of the heat inward.

@@shivercanada there this machine called the nimbus it uses dry ice(10lbs), it heats water (4gl) by 2 heating resistor (1800W each) has a metal basket that fill with dry ice and when the water gets hot you sink the basket into the hot water. It's not very efficient but does get trick done, It takes like 1hr to heat up the water with a single resistor. time can be cut in half by using the 2 heating resistors but you got to use a second cord. what I had in mind was to heat up water instantly with this, use a pump to spray it to the dry ice instead of sinking, also I was planing on using lit-poly cells(3.7v 200Amax) about 10-12 in series should give me the working voltage. I already have the inductor, batteries but don't know how to increase the heating coil, also I had read that heat inductors are more efficient on ferous metal, I was planing on using stainless steel Tube 1/4 or 1/8, do 4,6,8, passes thru the heating coil. I appreciate your time and input thank you.

Hey I got this on Aliexpress, it kind of does the job but I wouldn’t recommend it because there’s no way it’s actually 4000 W. I would recommend a “15 kW 100% load” induction heater box. They’re double the price but many many times better, makes a steel bar white hot, you can interchange coils and coil sizes and you can run it non stop all day without any damage to the unit.
