Billet Quality, Testing and Approvals

Billet quality starts in the melt shop. Kesari Alloys controls chemistry, gas content and cleanliness before casting, and tests the product afterwards.

Melting and casting

Electric melting furnaces
Ladle refining furnace for temperature, chemistry and sulphur control
Vacuum degassing system
Close casting, so liquid steel is not exposed to the atmosphere

See the continuous casting process.

Testing

Optical emission spectrometer for chemical analysis
Simultaneous oxygen, nitrogen and hydrogen analyser
PMI mobile spectrometer for grade verification
Radioactive contamination testing facility

See billet defects and quality checks.

Heat treatment and finishing

An electric car-bottom heat treatment furnace, 6.5 m long and rated to 1150 °C with temperature control, is available. Spot grinding and full grinding are available on request at extra charge.
