Question

Which of the following is the primary benefit of using the electric furnaces for melting the metals?

(a) High productivity

(b) Better quality of materials

(c) High strength of metals

(d) Less maintenance

This question was addressed to me in class test.

I need to ask this question from Electric Furnace topic in chapter Metal Furnace and Practice of Casting-Forming-Welding II

Answer 1

Right answer is (a) High productivity

The explanation is: The primary benefit of using the electric furnaces is the large reduction in the specific energy required to produce the metal. The ratio, energy per weight of the metal is reduced by using the electric furnaces for melting the metals, which directly hikes the productivity. So this method has high productivity.
