Q1: Why is the kiln car considered the most critical and essential equipment in the tunnel kiln?
The kiln car is the most expensive and impactful auxiliary equipment in the tunnel kiln. It directly determines whether the kiln can operate continuously and stably, the quality of fired products, equipment failure rates, and overall energy consumption. The kiln walls and roof maintain constant temperatures with heat loss mainly from conduction, while the kiln car repeatedly enters and exits the high-temperature kiln, enduring severe thermal cycling. It is the primary source of heat loss, equipment failures, and production interruptions in the entire line.

Q2: What production problems can poor-quality kiln cars cause?
Inferior kiln cars easily lead to deformation, jerky movement, collision with kiln walls, slag accumulation on the track, and even collapse of the car itself. In severe cases, this forces the kiln to be shut down and the flame extinguished, interrupting continuous production, causing capacity losses, increased maintenance costs, higher reject rates, and significantly reducing the economic benefits of the production line
