slag coagulation process in melting process

Smelting

Smelting

This process can be started up through vacuum induction melting. The ESR process uses the as-cast alloy as a consumable electrode. Electric current (generally AC) is passed between the electrode and the new ingot, which is formed in the bottom of a water-cooled copper mold.

Slag and/or Dross Formation Tendency

Welding slag is a form of slag, or vitreous material produced as a byproduct of some arc welding processes, most specifically shielded metal arc welding (also known as stick welding), submerged arc welding, and flux-cored arc welding.Slag is formed when flux, the solid shielding material used in the welding process, melts in or on top of the weld zone.
