Structural Design for Durability and Reliability

The RT3-300-8 Bogie Hearth Furnace is constructed with durability, efficiency, and safety in mind. Key structural features include:

• Furnace Shell: The furnace is housed in a welded steel plate outer shell with a thickness of ≥3mm, ensuring both strength and long-lasting durability. The frame uses 6-10# section steel for added rigidity, preventing any deformation during operation. The furnace exterior is coated with high-temperature paint to withstand extreme conditions.

• Lining Body: The interior of the furnace features high-quality refractory fiber, which provides excellent thermal insulation. This fiber lining reduces heat loss, contributing to the furnace's overall energy efficiency. The aluminum silicate fiber used in the furnace can withstand temperatures of up to 950℃, ensuring reliability and longevity.

• Furnace Door and Sealing Mechanism: The furnace door is constructed with a steel plate outer shell and fiber lining, ensuring a strong and durable seal. The self-compression structure of the door ensures no heat loss, and the door is equipped with an electric hoist for easy opening and closing. The special sealing mechanism between the door and the furnace body prevents air leakage and enhances energy efficiency.

• Bogie System and Traction Mechanism: The bogie system uses a high-strength steel structure, supported by ZG55# steel castings for the wheels. The trolley traction mechanism ensures smooth and reliable operation, allowing easy entry and exit of the workpieces.
