What is the working principle of the porous plug?

Inert gas (e.g., argon) permeates through the plug's micropores, forming fine bubbles in molten steel. The rising bubbles create turbulence for circulation and homogenization, while transporting non-metallic inclusions to the slag layer.

Product Q&A

Q:What are the main features of the Refractory Purge Plug?

The purge plug is characterized by high strength, good erosion and corrosion resistance, high blowing rate, and good safety. It effectively improves steel quality through gas stirring and composition homogenization.

Q:What types of purge plugs are available?

We offer Slot Plugs, Porous Plugs, Segment Plugs, and Hybrid Plugs. Each type is designed to meet specific refining conditions, such as ladle capacity, temperature, and steel grade.

Q:Can the gas channels be customized?

Yes, the gas channel can be designed and customized according to actual on-site conditions, including refining steel grade, workmanship, ladle capacity, temperature, and hydrostatic pressure.

Q:What are the requirements for refractories used in ladles?

Refractories for ladles must have high temperature resistance, thermal shock resistance, resistance to slag erosion, sufficient mechanical strength at high temperatures, and a certain degree of lining expansion.

Q:What are the chemical and physical properties of the purge plugs?

Properties vary by model (SNLWB-85/90/95). For example, Al2O3+MgO is min 85-95%, bulk density is min 2.9-3.05 g/cm3, and compressive strength is min 80-100 MPa. Specific data can be customized based on your steelmaking conditions.
