Why PS Converters Need Magnesia Chrome Bricks
Peirce-Smith converters are widely used in copper matte converting, running under severe high heat, cyclic temperature shifts, molten matte scouring and alkaline slag attack. The tuyere zone, slag line and converter mouth suffer the fastest lining wear, which directly shortens furnace campaign and raises downtime costs. Magnesia chrome bricks remain the preferred refractory lining for PS converters, thanks to balanced high-temperature performance that other magnesia series bricks cannot match. Our magnesia chrome bricks cover directly bonded and fused rebonded grades for zoned lining design of PS converters.
Core Performance Advantages for Matte Converting
Our magnesia chrome bricks feature stable periclase‑spinel mineral structure. They deliver excellent slag penetration resistance and thermal shock stability under frequent heating and cooling cycles. High hot strength prevents peeling and spalling when molten matte flows through. Controlled MgO and Cr₂O₃ ratios help resist alternating oxidizing‑reducing atmospheres inside the PS converter. Dense brick texture slows slag infiltration and reduces local corrosion at critical wear zones, extending lining service life and cutting your refractory replacement frequency.
Custom Zoned Lining Solution for PS Converter
Different positions of a PS converter carry different working loads. We supply graded magnesia chrome bricks for targeted zones: premium fused rebonded bricks for tuyere area, standard direct‑bonded magnesia chrome bricks for slag line and converter barrel, and economic grades for end walls. We can adjust bulk density, hot modulus of rupture and chemical composition according to your matte grade, operating temperature and maintenance schedule. Custom sizes, pre‑shaped blocks and on‑site technical support are available for your lining project.
