A drying furnace comprises a plurality of drying areas that are continuously provided along a longitudinal direction of the furnace and include a first hot air supply port, a second hot air supply port, and an exhaust port. The first hot air supply port is arranged at a position below a vehicle body in the furnace shell to discharge hot air diagonally upward. The second hot air supply port is arranged at a position higher than the first hot air supply port in the furnace shell to discharge hot air diagonally downward. The exhaust port is arranged at a position lower than the first hot air supply port and the second hot air supply port in the furnace shell to discharge the hot air outside the furnace shell. The drying furnace uniformly raises the temperature of the external and internal parts of the vehicle body while shortening the furnace length.

An apparatus for controlling the temperature of workpieces, in particular of vehicle bodies, has a temperature-control tunnel, a traction chamber and an intermediate floor which is arranged between the temperature-control tunnel and the traction chamber and which has a connection passage. The apparatus includes a conveying device for conveying the workpieces in the temperature-control tunnel, wherein the conveying device has at least one conveying carriage with a running gear and has a workpiece carrier for holding the workpieces of which the temperature is to be controlled. The running gear is arranged in the traction chamber and is connected by a connecting device, which projects through the connection passage of the intermediate floor, to the workpiece carrier arranged in the temperature-control tunnel. To control the temperature of the traction chamber and thus adequately protect the running gear against heat or cold, the intermediate floor is equipped at least in regions with an active cooling and/or heating means.

The present invention provides a water-based coating and/or coating system used to form sag resistant wet layers or coatings on a wide range of substrates. The coating system is effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. As an overview, the present invention provides water-based compositions as primer coats on substrates, and methods for applying the same to substrates. The method includes steps of applying a water-based paint to the interior surfaces of a substrate and drying the substrate by continuously forcing heated air onto the substrate as it moves through a drying chamber. Desirably, the primer incorporates a high level of one or more CAS agents for excellent sag resistance while drying in a broad range of relative humidity environments. Alternatively, modifications can be made to control temperature and humidity during spray application and drying as a way to increase sag resistance of the coating.
