Resurrection of a CFEI 100 KVA Induction Furnace

I totally agree, with all the protrusions it would be a royal PITA to fabricate. Something like that might be something to keep in mind though, if after the next cold snap you decide the heat exchanger needs a little less coolth and a little more warmth.

I actually USED it today - first time in months !
It was just a proof of concept sort of thing as I sort out the logistics of pouring from the tilting body single handed. I'd like to be able to pour into a conventional pouring ladle and thence into the mould but that implies pre-heating the ladle which has to be supported in the right place catch the charge from the tllting crucible. At the moment the whole furnace body is raised 9 inches on a dolly for convenience of moving about but that makes looking into the 'pot' a bit hard.
Plan is to put it in it's final operating position off the dolly and weld up a frame to hold moulds, ladles etc to sit on the floor infront of it. As it is at the moment the melt is up at chest level and leaves me very much in the danger zone when pouring. Once the melt is safely in a ladle it can be distributed to more than one mould on the floor.
But before then I need to clear a path from the Tractor Shed, via the Stable to the roller shutter door on the foundry so I can lift the furnace body off it's dolly with my forklift truck. There is a Zed purlin above it, and I got a block and tackle out to lift it but bottled out thinking bending the purlin and bringing the roof down probably isn't a good idea!
Still I did turn half a huge lorry piston into an ingot today :ddb: :ddb:

Andrew,
Congratulations on the progress you are making.
Have you studied how the centre of gravity moves as you tilt the machine with a full molten load? The legs look to me as though they don't extend forward far enough. When you get it finally positioned and off the dolly, shall you rawlbolt the legs to the floor?
awemawson:
Thanks Pete for the kind words.
Remember that it's sitting on a slightly wobbly dolly at the moment. I probably won't bolt it down but will be adding significant weight in the form of some flag stones sitting on the base. I may change my mind though when I've used it with a heavier charge :bugeye:
