Author:
Improve quality and efficiency, save energy and reduce costs.
——The first 2024 Green and Intelligent Hot-Working Workshop on Three-Waste Treatment Technologies was successfully held.
On August 23, 2024, the first Green and Intelligent Thermal Processing Workshop—Technical Exchange Meeting on the Treatment of Three Wastes was grandly held. The meeting was organized by Chongqing Fengdong Metal Surface Treatment Co., Ltd., with co-organization by Nanjing Kerun Industrial Media Co., Ltd. The event invited three distinguished experts: Chang Qing, an expert from the Chongqing Environmental Protection Association; Chen Shaolong, a heat treatment expert; and Qing Quan, another heat treatment expert. Also in attendance were representatives from over 20 client companies, including Aisidi (Chongqing) Drive System Co., Ltd., Chengdu Tianma Railway Bearing Co., Ltd., Guizhou Qunjian Precision Machinery Co., Ltd., Lizhicheng (Sichuan) Machinery Co., Ltd., Luzhou High-tech Zhonghang Transmission Steering Systems Co., Ltd., Luzhou Yangtze Machinery Co., Ltd., Sichuan Hongfeng Machinery Co., Ltd., Sichuan Zhongyou Machinery Co., Ltd., Yibin Tiangong Machinery Co., Ltd., Yu Yang Gear Co., Ltd., Chongqing Haoneng Xingfu Synchronizer Co., Ltd., Chongqing Hualing Industrial Co., Ltd., Chongqing Construction Industry Group Co., Ltd., Chongqing Landai Transmission Machinery Co., Ltd., Chongqing Akita Gear Co., Ltd., Chongqing Sudeng Machinery Co., Ltd., Chongqing Xiemǎ Crankshaft Co., Ltd., Chongqing XinXing Gear Co., Ltd., Chongqing XinXing Universal Transmission Co., Ltd., Chongqing Xingji Gear Co., Ltd., and Chongqing Yongda Machinery Co., Ltd.—totaling approximately 50 participants.
During the meeting:
1. Changqing experts interpret the environmental protection policies for the heat treatment workshop and share their environmental protection philosophies.
2. Wang Shun, Production Manager at Chongqing Fengdong, shared insights on three topics: “Oil-Fume Treatment Equipment,” “Automatic Feeding Mechanism for Heat Treatment Production Lines,” and “Electrical-to-Gas Conversion for Heat Treatment Equipment.”
3. Zhou Xuedong from Nanjing Kerun introduced the automatic anti-seepage coating machine to everyone.
4. Zhang Jinyue, a technical expert from Chongqing Fengdong, shared knowledge and practical experience on multifunctional oil filters and oil-water separators.
5. Li Linhai, Technical Director of Shanghai Baohua Wei, introduces the RX series heat-absorbing gas generator.
6. Lei Taiyong, Sales Manager at a blue-chip company, introduced the propane distributed energy supply system to everyone.
7. Heat treatment expert Qing Quan shared “Pain Points in Heat Treatment and Equipment Requirements.”
8. Mao Tao, Deputy General Manager of Nanjing Kerun, introduced equipment for the full lifecycle maintenance of industrial media.
9. Heat treatment expert Chen Shaolong shared “Direct Quenching of 20Cr2Ni4A Steel After Low-Temperature Carburizing.”
10. During the meeting, we’ll provide detailed and attentive explanations to customers who need them during tea breaks and informal networking sessions.
After the meeting, Yin Youzhi and Gao Xinjie from Chongqing Fengdong led teams of experts and customers on a tour of the Chongqing Fengdong factory. During the visit, they observed firsthand Chongqing Fengdong’s innovative practices and applications of three-waste treatment and green, intelligent technologies in its heat treatment workshop, helping various enterprises achieve green intelligence, improve quality and efficiency, and foster win-win collaboration.

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.
