when I Lance out pins I use a much shorter rod, and weld a small piece of angle iron just off center to use as a guide. I would say they left a half inch deep crater in floor

A thermal Lance is basically the same process of when your shop teacher shuts off your acetylene when you making a long cut on plate steel with a oxy/fuel torch. Basically, you get the metal hot to the point of actually being burned away and once the reaction is occuring between the burning iron and the oxygen, it can be maintained as long as the burning iron is fed into the flame at the right speed, except it's a helluva lot harder to do it on plate, as opposed to having the tip of the torch being completely surrounded by the molten and soon to be burned, metal like a lance.

Exactly. How hard is it to park over some dirt or gravel or failing that get a tray or a sheet of cheap plywood and put down a layer of sand to catch all of the molten slag.

They are a great tool when there is a person with a brain on the business end. I bet there concrete had some bad holes burned in it because they were to dumb to put some steel plate down to catch the molten metal.

I had a pin stuck i could not get to move in a similar place even when heated so i ended up using a saws all to squeeze in between where the grease would normally show and cut the pin in 2 places. Then you can remove the stuck pin with the outrigger and place it in a press to really force it out. I think i used a sledge but i could get a full swing blow straight down once removed from the rest of the backhoe. The point is once cut loose from the rest of the backhoe it becomes easier to manipulate and it divides the pin into 3 pieces. (someone maybe called this the affair slice method?)

I've gotten at least over 100 of this out and I'm 32 . next time a little head and a 80 lb jack hammer its out in about 45 secs on that size pin ,in a old pin . that thing is to new to not get out easier. unless it was bent . that's a bitch . but learning is growing love this kind of work

@Ruben901

Heat makes the pin expand, by creating a hole in the center of the pin, your making more space for that pin to shrink in size when cooling. That way it can push out easy with a hammer or a Vice press

You are correct tho. Once metal reaches the “red hot” stage it will never have its original strength unless it is reheated to a certain temp and cooled at the correct speed/temperature. Not all metal needs to be super tough for its purpose tho so this could possibly be fine for this application

My GOD, I hope know one paid good money for 3 or 4 guys to extract that pin, tube operator doesn't even know if he's "going at and angle". You could place a simple homemade guide a few feet back from the pin or use a level and a square, or a hair larger tube over your "lance" secured to a couple of jack stands a couple feet apart. Set up is everything, lots of ways to make sure your close to being straight, rather than ruining the bore of what appears to be a newer machine... 👀

Should ignite the lance first instead of burning the pin. These people don't know how to use the lance, probably don't have enough oxygen flow through the lance.

This is wild. it appears that that oxy-fuel melting/cutting is a self sustaining process. So if you heat the metal to a molten state and just add oxygen you don't need to add any more fuel to keep it going? I did not know that.

learned the same thing today in class, It's deceptive watching someone do it because the acetylene is burning but that's only to heat the metal to a reactive temp and so you don't have to relight it every time you turn the oxy get off

Rich MAC it’s being reduced by the oxygen. The O2 is stealing irons electrons. This is technically a thermite reaction I believe.
@davidwilmshurst4616

@@Chemist4271 - No It is not thermite. Nor is it reducing. It is just rapidly oxidising the steel. The heat evolved by the oxidation is greater than the rate at which the heat can dissipate, so, it is self-sustaining. Exactly the same as Oxy cutting. Thermite is a blend of aluminium or magnesium powder and iron oxide powders. Heating it causes a reaction to take place. The oxygen bitties would rather live with the light metal(s), yielding iron metal. Whilst I have watched lancing before on a much bigger scale, I have never worked out why the surrounding metal does not get burnt. Only the shaft. Conductivity?
