Lean Management in Heat Treatment Production

Heat treatment is an important component of the mechanical processing industry. Within the industry, there are two main types of production methods—each differing in scale and nature: one is small-batch, order-driven production for individual parts, and the other is a multi-batch, high-volume production model. In recent years, with the rapid development of the machinery industry, the heat treatment processing sector has also experienced swift growth. However, the technical standards and management practices in this sector remain unstandardized, resulting in suboptimal economic and social benefits. For enterprises seeking to grow and enhance their economic performance, it is essential to broadly analyze potential issues in heat treatment production while prioritizing quality improvement and cost reduction. Moreover, it is crucial to proactively identify and address possible problems at an early stage. By adopting lean management principles, optimizing processes and workflows, and standardizing operations and procedures, we can ensure that heat treatment quality is inherently built into the manufacturing process rather than merely inspected afterward. Only by earning greater customer trust and securing more orders can we effectively reduce heat treatment production costs.

Methods for Controlling Residual Austenite in Heat Treatment

After quenching, parts invariably retain some residual austenite, to a greater or lesser extent. Excessive residual austenite is detrimental to the service life and hardness of the parts, potentially leading to soft spots and dimensional instability. However, a moderate amount of residual austenite can actually enhance the fatigue strength of the parts. By carefully controlling the level of residual austenite, we can effectively manage product quality and service life, thereby achieving the desired outcomes.

Classification of Heat Treatment Cracks

Quenching cracks—longitudinal cracks (microstructural stress type), arc cracks (local tensile stress type), quenching cracks in large workpieces (longitudinal and transverse fractures), surface cracks along edges and contours (local tensile stress type), decarburization cracks, and Type II stress cracks.
