Purging plugs serve as the critical gas injection elements for bottom blowing in steelmaking. Based on their installation method, the industry primarily adopts two types: internally mounted monolithic purging plugs and replaceable, externally mounted split-type purging plugs. While the slit structure is a common gas channel design, our company has pioneered the development of a new-generation dispersive purging plug.
The dispersive purging plug features high porosity and superior permeability. In our manufacturing process, this is achieved by incorporating carbon-containing compounds into the raw material mixture. These compounds combust completely at low temperatures without leaving any residue, creating the initial, finely distributed porosity network through a controlled low-temperature firing process.
Provides finer, more uniform bubbles for improved stirring efficiency and refining performance.
The micro-porous structure reduces the risk of blockage compared to traditional slit designs.
Excellent thermal and mechanical shock resistance ensures reliable operation throughout the campaign.
Available in both monolithic and split-types to meet varied operational and maintenance needs.
