Bench-top Tempering Furnace & Ovens

Compact & Efficient Tempering Solutions for Small-Scale Heat Treatment

Product Introduction

Our Bench-top Tempering Furnaces & Ovens are compact, efficient, and user-friendly heat treatment solutions specifically designed for small-scale tempering operations. Ideal for laboratories, small workshops, educational institutions, and hobbyists, these furnaces provide precise and uniform heat treatment of small components after hardening or quenching. Tempering is a crucial process that reduces the brittleness of hardened steel, increases its toughness and ductility, and relieves internal stresses, while still maintaining sufficient hardness. Despite their smaller footprint, they deliver excellent temperature uniformity and control, crucial for achieving consistent and predictable material properties. These bench-top units offer a cost-effective and reliable solution for a variety of metal heat treatment applications where space and budget are considerations.

Working Principle

Bench-top tempering furnaces operate on the principle of heating small metal components to a specific temperature below their critical point to modify their microstructure and mechanical properties. This process, known as tempering, is typically performed after hardening or quenching to reduce brittleness, increase toughness and ductility, and relieve internal stresses. The compact size of these furnaces makes them suitable for small batches and laboratory settings.

Components are loaded into the small heating chamber, often on a tray. The furnace then heats the components to the desired tempering temperature, typically ranging from 150°C to 650°C. To ensure excellent temperature uniformity, which is crucial for consistent tempering results, these furnaces are usually equipped with forced air circulation fans. These fans circulate the heated air throughout the chamber, ensuring that all parts of the load receive uniform heat treatment. This convective heat transfer is highly efficient and effective for achieving precise temperature control in a compact space.

During the soaking period at the tempering temperature, the unstable martensitic structure (formed during quenching) transforms into a more stable and tougher microstructure. After the soaking period, components are typically cooled in air. The entire process is managed by digital PID controllers, which maintain the set temperature with high accuracy, ensuring repeatable and high-quality tempering results for small-scale applications.
