Ladle Purging Plug for Steel Industry
Application Industry: Refractories for Steel Industry
Application Equipment: Ladle Bottom Purging System for Argon Blowing
Size: Custom purging cone geometry per ladle bottom design (free engineering on request)
Products Overview
Our Ladle Purging Plug is a high-performance refractory purging cone engineered for ladle bottom argon blowing service. The product family is manufactured from high-purity corundum, spinel, and Cr2O3-based raw materials as the main aggregates. Various types of ventilated bricks such as through-hole type, directional slit type, directional labyrinth type, internal integral type, and external split type can be designed and manufactured according to user requirements. The matching ventilation block locking mechanism can be designed according to user requirements, featuring large adjustable range and high blow-off rate.
The Ladle Purging Plug product family is offered in three engineering-proven TQ chemistry grades for purging cone service. The CH-TQ1 grade features Al2O3+MgO+Cr2O3 content minimum 96% and Bulk Density minimum 3.15 g/cm³ with Cold Crushing Strength minimum 120 MPa for the highest-demand ladle purging service. The CH-TQ2 grade features Al2O3+MgO+Cr2O3 content minimum 94% and Bulk Density minimum 3.15 g/cm³ with Cold Crushing Strength minimum 100 MPa for high-demand ladle purging service. The CH-TQ3 grade features Al2O3+MgO+Cr2O3 content minimum 92% and Bulk Density minimum 3.10 g/cm³ with Cold Crushing Strength minimum 90 MPa for standard ladle purging service. All three TQ grades deliver Gaspermeability 20 to 50 Nm³/h at 0.1-1 MPa pressure range for steelmaking secondary refining argon purging service.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Ladle Purging Plug grade is engineered to ASTM, GB/T, and ISO refractory standards.
