Product Description



Product Description
Refractory porous plug is a key functional component used in steel ladle bottom gas purging systems. It is designed to inject inert gas (such as argon) into molten steel to achieve effective stirring, temperature homogenization, and impurity removal during the refining process.
Made from high-quality refractory materials, the porous plug offers stable gas permeability, high temperature resistance, and reliable performance under severe steelmaking conditions. It is widely used in steel plants for ladle refining and secondary metallurgy processes.
Features
Stable gas permeability for uniform gas distribution
High temperature resistance for steelmaking conditions
Good thermal shock resistance for repeated use
High strength structure with long service life
