Plastic refractory is a monolithic material with good plasticity, Al₂O₃ ≥65% and service up to 1600℃. Shipped as plastic pug, it is rammed into shape without formwork or heavy water addition, suiting irregular zones with good thermal shock resistance, high lining integrity and long life. It is Henan Songrui's professional grade for reheating/soaking furnace walls and arches.
Choose plastic refractory for irregular, arched or formless zones; castables are more efficient for large regular linings. Store pug moisture-proof to prevent hardening.
Scarify between layers for integrity; ram fully and bake per the dedicated curve. Construction guidance available.

Plastic refractory installed by ramming/pressing:
Rammed or pressed in plastic state, formable to any shape for irregular zones and local repairs—no formwork or curing.
Reheating furnace hearths/walls, soaking furnaces, sinter ignition furnaces, aluminum melters—especially local patching.
Plastic is flexible in shape and supports in-service patching; castable gives better integrity for large new linings.
