• Recycled steel is a key input needed for all steelmaking process routes. EAFs can be charged with up to of recycled steel and basic oxygen furnaces with approximately 30%.13 • Recycling this steel accounts for significant energy and raw material savings: over 1,400 kg of iron ore, 740 kg of coal, and
Where, Y= Output,, K=capital input, L=labor input and α+ β=1 (constant return to scale). A,α andβ = Technological parameters. The Cobb Douglas production function limitsthe substitution between factor inputs hence the elasticity of substitution is always unity. Its logarithmic form is as follows, LnY = lnA+αln(K)+ βln(L)
The steel ball or steel grinding ball are a material grinding media of ball mill and coal mill. It functions as an important component of ball mill under grinding and cutting effect brought by the friction between grinding balls or grinding ball and materials. It has an important position in national economy like cement plant and power station.
