Maximize Strip & Coil Quality with Our Protective Atmosphere Bell Annealing Furnace

In the precision-driven world of metal processing, achieving consistent mechanical properties in strips, coils, and tooth blanks is paramount. Wuxi Wondery Industry Equipment Co., Ltd. specializes in advanced thermal solutions, and our Atmosphere Protective Annealing Furnace is engineered for high-volume, high-efficiency normalizing and annealing processes. This robust system is a cornerstone for manufacturers in the non-ferrous and ferrous metal industries seeking to enhance product ductility, eliminate stresses, and refine microstructure.

Engineered for Performance and Durability

Our bell-type furnace system employs a versatile "one furnace body + one base + one muffle tank + one cooling hood" configuration. This design allows for continuous, alternating operations, where one load can be cooling under the hood while another is heating in the furnace. This cycle drastically reduces downtime, adapts to high-volume production lines, and significantly improves overall throughput.

Constructed with longevity in mind, the furnace features a high-integrity 310S stainless steel muffle tank, 12mm thick, ensuring a completely sealed environment for protective atmospheres like hydrogen or nitrogen. The 300mm thick ceramic fiber insulation minimizes heat loss, leading to superior thermal efficiency and a low body surface temperature rise.

Precision Control for Superior Results

Temperature uniformity is critical for consistent annealing. This furnace is equipped with a two-zone temperature control system, powered by a high-precision Japanese Shimaden SRS13A PID controller. This setup, managed via a user-friendly 10-inch MCGS touchscreen, guarantees a furnace temperature uniformity of ≤ ±8°C during the holding stage. A powerful 15KW water-cooled axial flow fan creates strong convection within the muffle, ensuring even heat distribution and eliminating cold spots.
