Causes of internal air extruded aluminium profiles

Long Rod hot residual shear causes air, long bars hot shear forming the shear plane is never perfect, industrial aluminum profile perpendicular to the long bar hot shearing makes string the simple bending of rods is very serious, aluminium profiles appear oval in cross section and are cut a very large round. Even the new long bars hot shear, shear column edge angle will always produce great rounds, the round is the best place to air trapping. Upsetting lead residue in the air, only in the containing cylinder diameter ratio of aluminum ingots when column Rod diameter. Post great talent enough to be put into the tube containing aluminum ingots. For columns containing aluminum tube inside the great pressure after causing the column tube diameter rods extend into ingots, must discharge the gas they carry. No emission of gases and residues inside the aluminum ingot is going into bubbles.
