METHOD OF STARTING ELECTROSLAG REMELTING PROCESS WITH MOLTEN SLAG

摘要

The starting up of an electroslag remelting process with molten slag, the volume of such slag being inherently variable within determinable limits, by positioning the bottom of the electrode preferably not more than 2 inches above the maximum anticipated slag level, charging the molten slag into the bottom of the mold within a period of preferably 1 to 4 minutes, and immediately thereafter with voltage applied to the electrode, lowering same at a speed of between 5 and 30 seconds per inch until contact is made with the top of the slag and a current flow is registered, the slag becoming highly fluid within a few minutes thereafter.
