The integration of high basicity slag helps in the desilication process, ultimately leading to a purer form of ferrochrome. Moreover, the vacuum solid decarburization refining technique is employed to convert high carbon ferric chromium into microcarbon ferric chromium with reduced carbon content. This precise control over the smelting processes ensures the production of ferrochrome with the desired characteristics and properties for different industrial applications.

Vacuum Solid Decarburization Refining

In the domain of ferrochrome production, the process known as Vacuum Solid Decarburisation Refining stands as a paramount method for transforming high carbon ferric chromium into microcarbon ferric chromium with exceedingly low carbon content.

In this refining process, finely ground high carbon ferric chromium undergoes oxidation in a vacuum furnace. The integration of water glass in a vacuum environment ensures the reduction of carbon content to achieve the desired low levels. Specific vacuum levels and temperatures are meticulously controlled throughout the refining process, which typically spans several hours.

The utilisation of this technique assures the production of high-quality ferrochrome. Notable features of Vacuum Solid Decarburisation Refining include:

  1. Controlled oxidation of high carbon ferric chromium.
  2. Operation within a vacuum environment to manage carbon content effectively.
  3. Precise control of specific vacuum levels and temperatures for optimal results.
