Porous Plugs

TYK Corporation is a world-wide supplier of engineered ceramic and refractory components used in the metallurgical industries, particularly the iron foundry and steel industries.

Porous plugs are sintered high alumina ceramics that have controlled porosity to allow for gas flow. Porous plugs are used in desulfurization of high sulfur base irons for ductile iron production and in steel desulfurization. Argon gas injection through porous plugs is used in ladle metallurgy for inclusion flotation, temperature homogenization, and degassing of steel melts.

Depending upon the application, different sizes, compositions, and configurations of the plug are needed to maximize plug performance and efficacy.
