FAQ 

Q1: What types of adhesives are suitable for this tunnel furnace?

A: The equipment is suitable for various adhesives used in metal bonding processes, including polyurethane adhesives, epoxy resin adhesives, acrylic adhesives, and various water-based or solvent-based metal coating adhesives.

Q2: How does the equipment ensure the safety of flammable gases generated during adhesive evaporation?

A: The furnace is equipped with a forced exhaust system and gas concentration alarm device. Explosion-proof heating tubes and explosion-proof pressure relief doors can also be installed as optional safety configurations.

Q3: Are there any limitations on the thickness and width of steel plates?

A: The equipment is a customized product. The tunnel width, inlet height, and conveying structure are designed according to the maximum dimensions and production requirements of the customer's steel plates.

Q4: Does the tunnel furnace consume a lot of electricity? Are there energy-saving solutions?

A: The equipment adopts zoned heating control and high-density insulation design to reduce energy consumption. Gas heating or waste heat recovery systems can also be selected to further reduce operating costs.

Q5: Can the conveyor speed be adjusted?

A: Yes. The system adopts variable frequency speed control, allowing operators to freely adjust the steel plate residence time inside the furnace according to adhesive thickness and curing requirements.
