Description

Technical Field

[0001] The utility model belongs to the technical field of track kiln cars for tunnel kilns, and in particular relates to a double-layer tunnel kiln car. Background Art

[0002] The kiln car is the equipment that carries and transports the blanks to the tunnel kiln for firing, and is the most important auxiliary equipment of the tunnel kiln.
