Production Technology

The chemical quality of the pig iron produced by Valinho meets the most rigorous national and international standards. For this, the company uses modern technologies in the manufacturing process, which guarantees competitive costs and product quality.

Siderúrgica Valinho has its own laboratories for carrying out chemical analyses, carried out by the wet method (gravimetry, titulometry, and complexiometry) and by Spectrometry (through an optical emission spectrometer), providing agility and accuracy to the results obtained.

Among the technologies implemented at the power plant are:

  • Atmospheric Protection System by Bag Filters;

  • Energy Co-Generation System by Thermoelectric;

  • Pig Iron Processing System by Drumming;

  • Blast Furnace Gas Washing System by Wet Way.
