IAS 2 Net Realizable Value Deductions for Factory Scrap Inventory
IAS 2 requires deducting factory scrap net realizable value from primary product cost, reducing inventory carrying basis and protecting gross margins.
Dry Metal Yield
Meaning
Casting efficiency measurements tracking the ratio of usable solid metal recovered to the total metallic charge fed into a furnace determine the true productivity of a smelting run. This measurement of recovery, designated as the dry metal yield, excludes the weight of slag, dross, and non metallic oxides generated during the melting process. It represents the actual material available for downstream manufacturing after accounting for all thermal and chemical losses.
Process Variable
Furnace temperature and flux chemistry exert a direct influence on the volume of metal lost to dross formation. Lower temperatures may prevent complete melting, whereas excessive heat accelerates the oxidation of reactive alloys. Refining these parameters optimizes the recovery rate during the melt cycle.
Measurement Protocol
Technicians weigh the cold, solid output of cast products and compare this mass directly against the initial dry furnace charge. This comparison isolates the metal from the moisture or oils that often inflate the weight of incoming scrap. It provides a reliable baseline for calculating scrap purchase costs.
Economic Implication
Small deviations in this percentage alter the profitability of a foundry when processing high value alloys. Suboptimal yields force increased purchases of virgin material to meet production quotas. This metric represents a primary benchmark for furnace operational auditing.
