Import Black Annealing Quenching Furnace — Buy in wholesale FOB from Supplier in China

The Black Annealing Quenching Furnace from Guangdong Shunde Seko Machinery & Technology Co., Ltd is designed for thermal treatment of steel pipes and tubular components, with a maximum operating temperature of 1000°C and uniform heat distribution across the chamber. It uses electric resistance heating elements with ceramic insulation, ensuring stable temperature control within ±5°C under standard load conditions. The furnace is built for continuous industrial operation and includes a programmable PID controller for multi-stage heating profiles.

Typical construction uses AISI 304 stainless steel for the inner chamber and mild steel with high-temperature paint for the outer casing. Standard models support batch loads up to 500 kg, with internal dimensions of 800 mm width, 1000 mm depth, and 1200 mm height. The quenching section, integrated into the design, allows rapid cooling via forced air or oil circulation, depending on the steel grade being processed. These features align with standard industrial practices for black annealing of carbon and low-alloy steels, where controlled cooling prevents surface oxidation and maintains dimensional stability.

This furnace serves manufacturers in metal fabrication, pipeline production, and automotive component supply chains, particularly those treating seamless steel tubes for pressure applications. Buyers typically require consistent microstructure refinement to improve ductility and reduce internal stresses. The unit is shipped disassembled for container transport, with standard packaging including foam padding and wooden crate reinforcement. Trade terms include FOB Guangzhou and CIF ports worldwide, with minimum order quantities negotiated per project scale.

Guangdong Shunde Seko Machinery & Technology Co., Ltd is a manufacturer based in Foshan, Guangdong, specializing in industrial heat treatment equipment for metal processing. The company’s facility is located at No.13 Haiyu Road, Leliu, Shunde, and operates with a focus on custom-engineered furnace systems. Its verification status on the platform indicates a harbor-tier supplier, suggesting active trade engagement and documented export experience, though no public records confirm certifications, revenue, or client lists.

The supplier does not claim to be a large-scale producer, nor does it advertise certifications such as ISO 9001 or CE. Its listing reflects direct manufacturing capability rather than trading activity. Response metrics show no recorded replies, indicating limited real-time communication capacity, which buyers should account for during pre-order coordination. The company’s product range includes annealing, quenching, and tempering systems, with this furnace being one of several models tailored to steel pipe treatment.
