The Argon Oxygen Decarburisation (AOD) process is used, amongst others, to adjust the composition of stainless steel to the correct specification.
Final removal of sulphur and phosphorus is achieved by the addition of our high purity AOD Calbux quicklime. The quicklime used in this process must have high overall purity and very low residual levels of calcium carbonate. Tarmac Buxton Lime is the only lime supplier in the UK to produce high purity AOD quicklime with low calcium carbonate residual levels.
Our high purity Calbux quicklime range is of consistent high purity and available in a range of particle size and reactivity to suite any iron and steelmaking process and offers:
- Consistent quality and chemistry
- Low carbon
- Medium to high reactivity
- Flexibility and security of supply
