Induction Furnace Electrical for Melting

The first step must surely be to carry out a detailed survey of the installation with the aim of reviewing its current condition, comparing it with current standards and legislation, and drawing up a list of works that will be necessarily completed before throwing the switch. If an individual with that capability is not on site, then the obvious thing is to recruit and hire that individual.

What happens next is determined by the content of the report that the individual supplies in response and the level of funding that is to be applied to it.

Bring in a furnace technician, after determining the brand and model # of the furnace.

We don't read minds.

you may want to consider this first step: to hire a company that may deliver electricity.

Amazing, it's stood for 20 years and you expect it to work first time?

One thing I'll almost guarantee, the power hoses will be shot along with the shell tracing.

What remedial work has been done?

Read the tag if you can.....Is there a generator on site?

Pity the picture isn't of the other side. you would see the power hose and trace cooling conections.

The power hoses are water cooled single core cables.

You need some serious help here. It sound s like your in for trouble if you do not hire someone to review this unit before pushing the go button. Do yourself and the rest of the folks a favor and call the manufacture for techincal person to come help you and do not try this yourself.

Induction furnaces need a "load" ( a heap of metal ) in the crucible before it will generate heat. As for what everyone else said you can ignore that, just make sure you have a will and don't involve anyone else.

Don't forget to make a video recording of it!

first you have to read the instruction manual ,carefully.second.before opening the manual you must have basic technical education to understand manual.

if you can provide me the pics of furnace ,i can suggest you the cooling and power connections .

Follow the instruction manual to the letter. No short cuts allowed, and hire a professional, preferably a representative from the actual company who manufactured the induction furnace, as they will know precisely what to look for. You, as the site engineer (if you are an engineer) should make a check-list of what is needed as you read the requirements in the manual. If you cannot check each item off the list (as present and operable), then do not move forward until it is done.

Make sure your life insurance policy is paid up if you do not plan to heed all advice.

Ok, since it is obvious you do not have the necessary documentation or the necessary knowledge to attempt starting this beast so I will help you out with some step by step directions.

1. Contact next of kin and close family

2. determine how much income will be needed by the surviving family members for next 20 years.

3. Contact reputable life insurance salesman.

4. buy policy in amount determined in step 2.

5. Do not tell insurance company what you are about to do.

6. Clear all other people from area.

7. put on PPE

8. Plug it in

9. Turn it on.

10.Tell me where to send the flowers

As he has reached upto us -

he would opt for technician with relevent field ; atleast for discussion so as to proceed further .

By the fact ; part of rectification demands such clear directives so that we would not damage existing equipments and would stand for trouble shooting .

And I agree Sivaa the OP did come here looking for something, Validation, permission, excuses, I am not sure what he thought he would find. What is being proposed is an extremely dangerous endeavour if not done properly by people who have experience and knowledge of the numerous dangers involved. To query a web forum for this kind of information is reckless to the point of criminal. Hire a professional.

If you have no voltage there's no sense in thinking about starting it.

If you have no cooling water, you'd better not attempt to start it.

If you have cooling water, never mind attempting to start it until you reline the furnace. After 20 years of sitting idle in whatever environment you are in, the insulation/refractory is surely damp and useless and would probably cause an explosion if you did start it.

After 20 years your cooling water system and all the circuits are almost certainly clogged or blocked or fouled beyond belief and would probably need severe cleaning measures taken to insure flow to all the components hooked up to it.

The cooling system, power supply cabinet and furnace coils all need to be pressure tested prior to any use even if it was filled with antifreeze or some other suitable fluid prior to the 20 year shutdown which based on connection to a cooling water tower is doubtful.

After all that is done, have the person who ordered it started stand there to throw the switch while you stand well in the background, preferably behind a thick concrete wall.
