Slagminut

Slagminut is a hypothetical unit used in metallurgical literature and process modeling to quantify the rate at which slag is produced in a furnace or reactor. It represents slag production as a mass flow per unit time, typically kilograms per minute, defined under specific process conditions.

Etymology and definition: The term combines “slag” with a form of the word minute (minut). It is not part of the official SI system, and different models may define the exact conditions—such as temperature, pressure, slag composition, and feed rates—to ensure consistent comparisons.

Applications: Slagminut is used mainly in teaching, simulation, and optimization studies of steelmaking, smelting, and slag valorization. By expressing slag production as a rate, researchers can compare different processes and scales without relying on circuit-specific terminology.

Standardization and limitations: Because slagminut lacks universal standardization, researchers typically report the governing conditions alongside the value. Caution is advised when comparing results from different sources, and it should not be interpreted as a physical constant.

Example: In a simplified model of an electric arc furnace, a slagminut of 12 kg/min might be cited under a defined set of input materials and operating temperature, serving as a proxy for slag management performance in the simulation.
