New Launch: Self-Developed Aerospace-Grade Pit Furnace Achieves New Breakthrough, Consolidating Domestic High-End Heat-Treatment Equipment Capacity for Aviation Manufacturing

Tianli Thermal Equipment has made important progress in the research and development of special heat-treatment equipment, with its self-developed aerospace-grade pit furnace officially launched. The successful development of this product fills part of the domestic equipment capability gap for precision non-oxidation gas quenching of key aerospace components, serving as a vital milestone for the enterprise in deploying high-end equipment for national strategic industries.

This professional aerospace-grade pit furnace adopts a full 304 stainless steel structural design, featuring outstanding high-temperature resistance, corrosion resistance and structural rigidity. It effectively resists thermal deformation and oxidative aging under long-term high-load industrial operation. Integrated with a mature PLC intelligent control system and high-efficiency precision gas quenching system, the equipment enables fully-automatic adjustable control over furnace temperature, gas flow, internal furnace pressure and holding time. Supported by superior furnace tightness and uniform internal temperature field, it delivers clean, non-oxidation and non-decarburization gas quenching heat treatment.

Specially developed for precision processing of high-end workpieces such as aerospace-grade titanium alloys and superalloys, it effectively stabilizes the dimensional accuracy of workpieces and improves the consistency of mechanical properties among batch-produced parts, fully satisfying the stringent process specifications and high-quality manufacturing standards of the aerospace industry.

Aerospace manufacturing is a core strategic sector of high-end equipment manufacturing, which sets extremely high thresholds for heat-treatment equipment in terms of performance, operational stability and process reproducibility. The independent development of this aerospace-grade pit furnace carries great significance. It provides reliable domestic equipment support for the manufacturing and localization substitution of key aerospace components, guarantees the safety and controllability of aerospace component production, and vigorously drives the iterative upgrading of domestic special heat-treatment processes and equipment.

As a national-level Specialized, Refined, Differential and Innovative “Little Giant” enterprise, Tianli Thermal Equipment has long been committed to tackling key technical bottlenecks in the heat-treatment equipment industry. Going forward, the enterprise will keep closely aligning with the major demands of national strategic industries, uphold self-reliance and self-improvement in science and technology, and further deepen R&D and innovation of high-end special heat-treatment equipment. It will roll out more domestic complete-set equipment solutions for high-end manufacturing sectors including aerospace, and make greater contributions to the high-quality development of China’s advanced equipment manufacturing industry.
