Tunnel kiln car linings face repeated heating and load abrasion; burning-zone brickwork and car tops are the critical zones.
Problem-by-problem analysis with solutions and recommended refractories
Steel-fiber reinforced castable with 2-3 vol% heat-resistant stainless fibers provides random reinforcement and toughening. Al₂O₃≥65%, 1400℃ max service, greatly improved flexural and thermal-shock spalling resistance.

Castable precast blocks are factory-cast, cured and fired to drawings with ±2mm dimensional accuracy, 1700℃ max service. Uniform quality with crane-installed placement that eliminates formwork, casting and curing—dramatically shortening outage time.
