Slag formation does not take place in the molten metal by using the electric arc furnaces.(a) True(b) FalseThis question was posed to me in an online quiz.This key question is from Electric Furnace topic in division Metal Furnace and Practice of Casting-Forming-Welding II

Answer»

Right choice is (b) False

Easiest explanation: Slag formation does not depend on the type of furnaces; it basically depends upon the type of metal used and the SURROUNDING GASES. Slag usually floats on the surface of molten metal which consists of metal oxides. It acts as a source of oxidized IMPURITIES and can help for reducing the erosion of the REFRACTORY lining material.
