Rose Bud Heating Problems

All the answers from the guys is a reason for your problems.

The only one that didn't get mentioned was a suction air leak at the tip(most likely for a air leak) or at one of the hose connections or a leaking valve.

As stated, your pressures are way too high for the task at hand. At 7psi Acet and 20psi Oxy is more than enough to heat a 3" solid shaft for strightening. It takes some time to preheat the metal. Your trying to work too fast.

If your working on harrow spring tines, then you will need to combine cold working metal with hot working methods. You want to heat the spring just enough to where it will bend where you need it to bend but not hot enough that it distroys the spring properities of the steel.

Where's the heat range at for proper temperature? You got me as I've never straighten harrow springs :)

My guess is about 700* then apply the ole" pipe cheater (cold method) to straighten then quench in oil (removes stress) then reheat too 500* then quench in oil (gives back the spring temper).

Hope that someone will chime in with experience working with harrow springs.

Caution is needed when you start running Actylene pressures that high, above 15psig it will become dangerous/explosive.

Tip is getting to hot , need to keep it out of the fire or get more flow thru it to cool it.

Unless you have a HUGE rosebud, I think your pressures are too high. I run my Harris rosebud at 8 psig for both the oxy and the acet. If you have the manufacturer's suggested max and min pressures for your particular tip, use them. Otherwise, I would try equal pressures that are lower. Rod
