The Tempering furnace is used for tempering general metal parts in the air and for quenching, annealing and aging Heat treatment of light alloy parts such as aluminum alloy die-castings, pistons and aluminum plates. The shell is welded with steel plates and section steel, and the trolley is also welded with section steel and steel plates. The trolley reduces heat radiation and convection loss through soft contact with the furnace lining and a sand sealing mechanism, effectively ensuring the sealing performance of the furnace body.

The tempering furnace is a periodic operation type tempering furnace, which is used for tempering general metal parts after quenching, as well as quenching, annealing and aging heat treatment of light alloy parts such as aluminum alloy die-castings, pistons and aluminum plates.

The types of tempering quenching properties in tempering furnaces

Embrittlement at 270℃ to 350℃ : Also known as low-temperature tempering quenchability, it mostly occurs in carbon steel and low alloy steel.

Embrittlement at 400℃ to 550℃ : Generally, alloy steels used in construction are prone to embrittlement within this temperature range.

475 ° C embrittlement: This particularly refers to the phenomenon of increased hardness and embrittlement in ferritic stainless steel with Cr content exceeding 13% when subjected to tempering treatment between 400 ° C and 550 ° C, which is particularly significant around 475 ° C.

Embrittlement at 500℃ to 570℃ : This is commonly seen in materials such as tool steel and high-speed steel during processing. At this temperature, carbides will precipitate, causing secondary hardening, but it will also lead to an increase in brittleness.

At the heart of the Mesh belt furnace lies its distinctive mesh belt mechanism. The continuously moving mesh belt serves as a conveyor, transporting workpieces smoothly and steadily through the furnace chamber. This design ensures uniform exposure of the workpieces to the furnace's controlled environment, whether it's for heating, cooling, or undergoing specific Heat treatment processes like annealing, carburizing, or tempering. The mesh structure of the belt promotes optimal airflow around the workpieces, enabling efficient heat transfer and minimizing the risk of temperature variations that could affect the quality of the treatment. As a result, each workpiece receives consistent processing, leading to high - quality and reliable results.

The mesh belt furnace is equipped with state - of - the - art control systems that enable precise regulation of key process parameters. Advanced temperature sensors, gas flow controllers, and programmable logic controllers (PLCs) work in tandem to monitor and adjust factors such as temperature, atmosphere composition, and belt speed in real - time. Operators can easily set and modify these parameters through an intuitive human - machine interface, tailoring the furnace's operation to the specific requirements of different materials and applications. For example, when processing metal alloys for the automotive industry, the furnace can be adjusted to achieve the ideal temperature profile for carburizing, enhancing the surface hardness and wear resistance of components like gears and shafts.

One of the most significant advantages of the mesh belt furnace is its high - throughput capacity. The continuous operation of the mesh belt allows for a seamless flow of workpieces, enabling high - volume production and significantly reducing processing times. This makes it an ideal choice for mass - production environments in industries such as electronics, machinery manufacturing, and automotive. In the electronics sector, where small components need to be heat - treated in large quantities, the mesh belt furnace can handle the demand while maintaining strict quality control. In machinery manufacturing, it can process a diverse range of parts, from small fasteners to large structural components, all with consistent and reliable results, improving overall production efficiency and product quality.

Designed with user - convenience and durability in mind, the mesh belt furnace features a modular construction that simplifies maintenance and reduces downtime. Key components are easily accessible for inspection, cleaning, and replacement, ensuring the long - term reliability of the equipment. Safety is also a top priority, with features such as over - temperature alarms, emergency stop buttons, and protective barriers integrated into the design to safeguard operators and prevent accidents. Additionally, some advanced models come with predictive maintenance systems that can detect potential issues in advance, allowing for proactive repairs and minimizing unexpected disruptions to production.

The applications of the mesh belt furnace are extensive and diverse. In the aerospace industry, it is used to heat - treat high - performance alloys for critical components like turbine blades and engine parts, ensuring they can withstand extreme conditions during flight. In the tool and die - making industry, the furnace plays a vital role in processes such as annealing and tempering, improving the toughness and durability of tools and dies. The food industry also benefits from mesh belt furnaces, which are used for baking, drying, and roasting products, ensuring consistent quality and even cooking. Moreover, in the medical device manufacturing sector, the precision and reliability of mesh belt furnaces are essential for heat - treating components used in surgical instruments and implants, enhancing their biocompatibility and performance.

From an economic and environmental perspective, the mesh belt furnace offers notable benefits. Its energy - efficient design, including high - quality insulation materials and optimized heating elements, helps reduce energy consumption, lowering operational costs and minimizing the environmental impact. The ability to process workpieces continuously and efficiently also reduces material waste, as the consistent treatment process minimizes the occurrence of defective products. This combination of cost savings and sustainability makes the mesh belt furnace an attractive investment for industries looking to optimize their production processes while reducing their carbon footprint.

In conclusion, the mesh belt furnace is an indispensable asset for industries that rely on heat treatment processes to produce high - quality products. With its innovative design, advanced control systems, high - throughput capacity, wide - ranging applications, and cost - saving features, it provides a comprehensive and reliable solution for achieving superior processing results. Whether for aerospace manufacturing, electronics production, food processing, or medical device fabrication, the mesh belt furnace is the key to enhancing production efficiency, ensuring product quality, and maintaining a competitive edge in the market.
