Ladle gas injection plugs (Ladle porous plugs)

For secondary refining like the LF process, stirring the molten steel via porous plugs is indispensable and the reliability of the stirring greatly influences steel quality.

The requirements of porous plugs are

*Resistance against molten steel penetration
*Corrosion resistance
*Thermal spalling resistance.

Primarily focusing on the reliability of the stirring effect, Krosaki Harima Corporation has been designing and developing high-quality porous plugs, and offering them in compliance with clients' operational conditions, e.g., the requested gas flow rate.

Upper layer of cylindrical permeable core + lower layer of cubic core = safety secured

For safety in hot operations, Krosaki Harima Corporation recommends the porous plugs which are configured in double layers, the upper layer a cylindrical permeable core and the lower a cubic one, for clear and accurate indication of the residual thickness to operators.
Supplying not only porous plugs but also well blocks and other peripheral devices like plug setting jigs, the corporation, with its extensive experience and performance as the largest supplier in the nation, provides more reliable steel stirring in our clients' operations.
