Long-product steel mill
The mill consumed calcium silicon in large, steady volumes and wanted to lock both cost and specification — with tolerances in writing and a delivery schedule that never interrupted the melt shop.
We put a standing contract in place covering a defined calcium silicon specification, written tolerances, and a rolling delivery schedule with buffer stock, supported by lot documentation.
Deoxidation cost per ton was stabilized, the specification held within agreed tolerances, and the melt shop ran without deoxidizer-related stoppages across the contract term.
A long-product steel mill uses calcium silicon in large, steady volumes as its primary deoxidizer, so both the price and the specification matter on every tonne. The mill wanted to move away from order-by-order purchasing — with its price volatility and occasional specification drift — to a standing arrangement that locked in both.
We put a standing contract in place covering a defined calcium silicon specification with written tolerances, a rolling delivery schedule, and buffer stock held to keep the melt shop supplied. Each lot shipped with documentation so the mill could verify chemistry against the agreed window. Where the mill’s practice benefited from a complementary deoxidizer, we supplied it under the same arrangement.
Deoxidation cost per tonne was stabilized for the contract term, the specification held within the agreed tolerances, and the melt shop ran without deoxidizer-related stoppages. For a high-volume consumer, the value of a documented, on-schedule bulk supply is often as large as the price on the material itself.
