Application:
- CUSTOMER’S PROBLEM
- Frequent scrap charging delays
- Frequent stoppages due to refractory repairs
- Noisy furnace during meltdown and refining
- DIAGNOSTIC
- Poor foamy slag practice
- Slag build-up in the furnace
- Tap selection and hence arc length, in absence of sufficient foaminess, damaging refractory and causing energy loss.
- Oversize scrap and bucket loading practice
- ACTIONS
- Changed the ratio of the lime and dolomitic lime added, as well as, the practice to improve slag basicity and foaminess during the entire heat process
- Involved third party to improve tap selection and arc length optimization
- Worked together with customer to improve scrap selection and loading practice
