Slag Outlet: Diameter 50-300 mm, Flow Rate 5-50 L/min

Component Specifications

Definition

The Slag Outlet is a critical component in separation chambers and launders, designed to facilitate the controlled removal of slag—a byproduct consisting of impurities, oxides, and non-metallic materials—from molten metal during smelting, refining, or casting processes. It ensures efficient separation of slag from the desired metal, maintaining process purity and preventing contamination.

Working Principle

Operates based on density differentials and gravity separation. Slag, being less dense than molten metal, floats to the surface. The outlet is positioned at the top or side of the chamber to allow slag to be skimmed, drained, or tapped off, often using mechanical or pneumatic mechanisms for controlled discharge.

Materials

High-temperature resistant materials such as refractory ceramics (e.g., alumina, zirconia), graphite, or alloy steels (e.g., 310 stainless steel, Inconel) to withstand thermal stress, corrosion, and abrasion from slag.
