Sintering furnace issue

[NicelyMKV]

Look what I walked into this morning...... Backed up as it is, 10 to 12 hours 6 days a week and had 30 units I had to sinter today and 40 more the next...... Oh well part of it, I know..... Only 6 months old though

Can't see the picture Jason .

Did the power kick and shut down your furnace?

I have FIVE furnaces with Two more on a boat to me., due in a week.

Always need an extra One or Four to have as back-up, and many extra trays and beads and elements .

We always check elements before sintering! ALWAYS!

What's the problem?

We are ordering even Two more furnaces with Argon chambers for powdered metal milling and for Zirconia!

That will make NINE furnaces for me! LOL

We try to never sinter overnight.

I have saved a cycle in the middle, by "jumping" a broken element with wires to finish the cycle with only Three elements.

(Auto Jumper Cables work for this! LOL)

Also changed an element right in the middle of a cycle before!

You need multi-meter to diagnose without opening the chamber door.

That's how we roll!

I had something similar a week or two ago with my BIG furnace.

It was shooting lightning inside! (SPARK SPARK POW!)

I ran over and shut'er down and re-worked some connections and back in action.

DONT SINTER OVER NIGHT! We usually do not.

If you were there, you could have heard this and save it.

The corrosive Acidic gasses do mess up the connections in the electrical section of the furnace.

When electricity gets passes through a small contact area, it obviously get very HOT.

Need to grind and polish all metal connections to have maximum surface area touching.

I learned this lesson as well Jason, but it only cost me 1/2 hr of labor.

I'll snap a pic of mine...I saved it before it went up in flames. LOL

Di-electric grease will prevent connections from corroding if you re-assemble it with a new wire.

The plastic control box itself is melted and broken off..... Wonder if grainger would have this bad boy?

[DMC]

It looks bad, but I bet you can get it working again!

Seriously.

I need to see more pics!

Forget melted plastic.

Geeze I feel for you Jason.You don't need that.

You've convinced me to outsource my zirconia forever!

 

[NicelyMKV]

Lol. I went against what I preach to everybody else and it bit me right in the can never again

Sorry Jason, sucks to try and save a few bucks only to get it to cost you more, been there done that!

You know, you get what you pay for, or you can jump through the hoops like Scott and use jumper cables and make lightning or just buy German and just "Set it, and forget it"

No kidding....looking for the Beep beep sweep!
