Diagnostic Methodology for the Energy Efficiency Estimation in Small Metal Casting Industries.

Abstract

This study will develop a methodology to measure and find the energy efficiency in arc furnaces, crucible furnaces and cupola furnaces. Those are the only ones used in the small metal casting industries in Cali.

The methodology initiates with the elaboration of a survey and contacting a sample OF local companies, then, continues with technical visits, measurements, analysis and results and finally, we obtain conclusions and give some specific recommendations to the companies

As a result, the first documented characterization were done, where is shown: size of the industry, energetic resource used, level of technification (modernization), fused metal, smelting method and kind of furnace, it is also presented the validation methodology and the identification of critical points where they can obtain big energy savings.
