Frosty Posted March 23, 2009 Share Posted March 23, 2009 Ayup, that's induction heating. Frosty Quote Link to comment Share on other sites More sharing options...
Ferrous Beuler Posted March 23, 2009 Share Posted March 23, 2009 Yes, that is induction heating. I saw another vid somewhere on youtube showing another one. I was amazed at how fast a heat was taken. That bit from 1:15 to 1:35, what sort of blacksmithing technique is that???? Quote Link to comment Share on other sites More sharing options...
Sabre Posted March 23, 2009 Share Posted March 23, 2009 yes it is!!, i think its cool, wonder how much power it uses...... Quote Link to comment Share on other sites More sharing options...
TASMITH Posted March 23, 2009 Share Posted March 23, 2009 I don't know how much power they consume but I do know that when we put a new addition on one of our plants and installed three Lasco hammers each with their own Induction heating coil units Ontario Hydro run a seperate high voltage transmission line into the plant to supply the power. I do know that they convert the power input to an extremely high frequency and that they could heat an 1 1/2" rd bar from room temperature to 2250 deg F in under 20 seconds! They used to run about 3 1/2 bars of 1 1/2" rd per minute when forging large connecting rods in the hammer. Terry Quote Link to comment Share on other sites More sharing options...
dablacksmith Posted March 24, 2009 Share Posted March 24, 2009 from the people who run them ive been told that they dont add apreciably to your electric bill...ive seen one used at a demo and if i had the bucks would really like one!

brianbrazealblacksmith Posted March 24, 2009 Share Posted March 24, 2009 Grant Sarver, Off Center Forge, was working on making an affordable induction forge the last time I saw him. When I saw it I was amazed and asked him if he had ever welded with it. He said no, but the next day at the ABANA conference he said he did weld with it that night after we left. If I could afford one I'd have one. It would save a serious blacksmith alot of time and money in just the heat time, and not to mention the comfort of not as much radiant heat or coal dust.

HWooldridge Posted March 24, 2009 Share Posted March 24, 2009 They are great for consistent sizes - in other words, repetitive work of a certain size and I'm sure an induction unit is the cat's meow for toolmaking. They are not as useful for odd sized stuff, like scroll work. Quote Link to comment Share on other sites More sharing options...

johnptc Posted May 6, 2009 Share Posted May 6, 2009 a 15 kilowatt unit will work nicely for a bladesmith Quote Link to comment Share on other sites More sharing options...
Nakedanvil - Grant Sarver Posted May 14, 2009 Share Posted May 14, 2009 Hi guys! I'm Grant Sarver and I've been selling a small unit for about five years now. It's 15 KW (that's about 50 amps on a 220 single phase circut) and about the size of a tower computer. It will heat about 15 inches of 1/2 inch bar in about 15 seconds! You can get a nice welding heat in 20 seconds. Coils are easily made from common 1/4 inch copper tubing. A short coil of about 2" diameter will heat a wide variety of parts. Longer heats can be had by moving the part back and forth thru the coil. Six inches from the anvil if you like! I've seen Darryl Nelson do an upset square corner on 5/8 bar in two heats with his. In my shop I went from about $250 - 300 per month in propane to where I saw about $25.00 - 30.00 per month increase in my electricity! I manufacture the OCP or Off Center brand of tongs and swages etc. Oh yeah, $2,995.00 Quote Link to comment Share on other sites More sharing options...

Nakedanvil - Grant Sarver Posted May 14, 2009 Share Posted May 14, 2009 (edited) Note there is a small piece of ceramic in the coil to support the bar. The unit in pic 1 uses a separate output transformer with a six foot cable from the power supply. The unit I sell the most of today has the output transformer and power supply in the same box. There is a fair power loss associated with the cables. Edited May 14, 2009 by nakedanvil Quote Link to comment Share on other sites More sharing options...
Frosty Posted May 14, 2009 Share Posted May 14, 2009 Ah HAH Grant! Really good to have you aboard buddy! I know I welcomed you earlier but now I know you is YOU I'll make it a bit more personal. Frosty Quote Link to comment Share on other sites More sharing options...

Jmercier Posted May 27, 2009 Share Posted May 27, 2009 Someday I plan on owning one of these =) Unfortunately that someday is after I get a power hammer in my shop. I just got a digitally controlled electronic heat treating oven, so the last (major) tools that i can even /think/ of that I want in my shop are a hydrolic forging press, power hammer, and induction forge. I do more bladesmithing than anything else, and it seems that an induction forge would be wonderfully suited to bladesmithing, however I dont know a single bladesmith off hand who actually uses one. If I could afford it, I'd love to be the first =) If anyone knows of a bladesmith currently using an induction forge, pass their info along, i'd like to talk with 'em.

dlpierson Posted September 8, 2009 Share Posted September 8, 2009 That's just sick! I've been wondering what the coil for heating flats looked like. Thanks a lot for showing it. One of these is very, very likely to be the next major purchase for my shop. Unfortunately that won't be very soon. There's this "major" part...

thingmaker3 Posted September 8, 2009 Share Posted September 8, 2009 Grant, how many watts does that gizmo pull from the wall outlet? Quote Link to comment Share on other sites More sharing options...
Nakedanvil - Grant Sarver Posted September 8, 2009 Share Posted September 8, 2009 thingmaker2: It runs on 220 single phase, takes about 50 - 60 amps. 'Course it's only drawing juice when you're heating steel. Quote Link to comment Share on other sites More sharing options...
781 Posted September 8, 2009 Share Posted September 8, 2009 Grant Does that price include a chiller or is that a seperate cost. I have seen Dave and Babe's machine used a couple of times and was impressed but he had his hooked to a chiller for a tig machine. Quote Link to comment Share on other sites More sharing options...
JDH Forge Posted September 11, 2009 Share Posted September 11, 2009 I took the plunge and ordered a unit from Grant... Glad I did... very impressive..... And Grant is just the best when it comes to help and service both before the sale and after... Of course... I was a little more of a "high maintenance" customer... If folks are interested ... I'll post some pics of the whole unit and set up from opening the box to set up, plumbing and first fire up...;) Quote Link to comment Share on other sites More sharing options...
