Common FAQs for Tunnel Kiln Car (Masonry Process Issues)

Q1: What production hazards can result from poor kiln car masonry quality?

Answer: The masonry standard for kiln cars is equivalent to that of the kiln body. Excessive joint width, poor flatness, unreasonable expansion joint reservation, and untimely removal of debris can cause green brick stacking to exceed limits, scraping the top or hitting side walls during kiln entry, failure of thermal seals, increased energy consumption, and seriously affect firing results.

Q2: How to avoid problems of green bricks exceeding width/height and jamming during kiln entry?

Answer: Set up inspection stations on the return track and at the kiln inlet to pre‑inspect the loaded kiln cars, preventing oversized green bricks from entering the kiln, ensuring smooth operation of the kiln cars throughout the entire process.

Q3: What are the advantages and disadvantages of cast‑in‑place kiln cars compared to masonry ones? What precautions are needed?

Answer: Cast‑in‑place kiln cars offer better thermal insulation, sealing, and energy saving, but they are more difficult to repair after damage. During use, care must be taken to prevent blocks and debris from falling into the kiln, so as to avoid damaging the curved seal structure, causing car derailment, overturning, or other safety incidents.
