slagplaat

Slagplaat is a term used in Dutch metallurgical contexts to refer to a plate designed to interact with slag, the molten or semi-solid byproduct produced during smelting, refining, or welding. It can be a permanent lining element or a removable component.

Its main function is to collect, deflect, or shield equipment from slag and excessive heat. By providing a sacrificial surface, the slagplaat protects refractories, walls, and vessels from slag attack and thermal shock. In some installations, it also helps channel slag to a trough or collection hopper for easier removal.

Materials and construction: Slagplates are typically made from heat-resistant steel, cast iron, or refractory ceramic materials, sometimes with protective coatings to improve slag resistance. They are installed as linings, plates, or detachable panels and may be shaped to fit specific geometries in furnaces, ladles, or transfer chutes.

Applications: Common in primary and secondary steelmaking, non-ferrous metal smelting, and welding workplaces where slag deposition on surfaces is a concern. They may be used as interior linings of furnaces, as slag traps near tapping points, or as protective fronts for workbenches and ramps.

Maintenance and lifecycle: Slagplates are monitored for wear, spalling, and loss of integrity. When slag adhesion becomes excessive or the backing shows deterioration, the plate is replaced or resurfaced.

Etymology and regional usage: The term slagplaat is Dutch; equivalent terms in other languages vary, such as slag plate or slag-related lining components.
