I agree with you with the boron nitride, now we're using boron in most of our new installations. With regard to the cut of the billet, a hot saw is a good solution to replace an old hot shear (with a bad quality cut), but you'll increase the scrap. If you have a good hot shear with a clean cut (as you can see in the video), the system will be more efficient.

Yes, the extrusion is a metallurgical process and the temperature alignement is a key factor. The quality of the clamps and the hot shear design is very important also

We do work for an Aluminium extrusion company and ive just sharpened a set of billet shears as they where having problems with the cut "Rugby balling" the cut ends of the billets,any views on this type of problem ?

how much does it cost to install the automatic system of the hot shear that moves the aluminum ingot to the press? and the crane that takes the extrusions to the cage????

how hot is the billet at the shear Process ? Or, how do you get a clean cut with the shear, is the temperature of the billet or the temperature of the shear important?

Mad Matt I believe the temperature of the billet is about 30 billion degrees celsius.

where I'm at, the butt (end of the billet that gets sheared off), is around 975 degrees F or more. The billet's entry temp is between 800-900 (depending on the type of part and alloy). The hotter the butt is, the softer it is which means it shears a bit easier. A sharp shear can help, but we also use wax on the shear when the butt starts sticking to the shear or gets stuck on the back of the die. The shear is heated by the continuous cutting of the hot billets and with the billet container being so close to the shear. The shear should be close to the die so there isn't too much excess left after shearing. It's important that the butt is sheared as close to the die as possible because the butt contains impurities that shouldn't be extruded in the finish. Another component of the shear is a "butt knocker" so after the cut, the but likes to stick to the shear. The butt knocker does exactly what that name implies. another part of the shear shoots down to knock the butt as the shear is near the end of the cut.
