Catalytic converter housings and environmental protection equipment: Precision manufacturing of large and economical spark wire cutting

Driven by the "dual carbon" goal, the environmental protection equipment industry has experienced explosive growth. As the core component of the exhaust gas treatment device, the manufacturing precision of the catalytic converter directly determines the performance and life of the equipment. However, the complex shell structure, highly corrosion-resistant materials and strict dimensional tolerances have put many companies in a dilemma of "difficult processing and high cost". How to break the deadlock? The answer lies in the innovative application of spark wire cutting technology.

Case analysis: Difficulties and breakthroughs in processing catalytic converter housing  

Take a well-known environmental protection equipment manufacturer as an example. Its catalytic converter housing is made of 304 stainless steel, with dimensions of 1300mm×1000mm×2100mm and a wall thickness of only 3-5mm. It must meet the following stringent requirements:

1. High-precision cutting: The shell needs to integrate multifunctional cavities such as catalytic beds and heat exchangers. The tolerance of special-shaped holes needs to be controlled within ≤±0.00 6 mm to ensure uniform airflow distribution and efficient heat recovery.

2. High temperature resistant structural stability: When operating at 200-300℃ for a long time, deformation caused by thermal stress must be avoided during processing to ensure sealing.

3. Complex geometric molding: The installation groove of the honeycomb catalyst carrier needs to be precisely matched. Traditional milling is prone to burrs, which affects the uniformity of the catalyst coating.

Zhikai CNC solution:  

Using large economical spark wire cutting machine tools, breakthroughs are achieved through the following technologies:

Adaptive tension control: To address the problem of easy deformation of thin-walled stainless steel, the electrode wire tension is dynamically adjusted to reduce the straightness error to 0.01mm/m.

Multi-axis linkage compensation: To cope with special-shaped contour cutting, 5-axis linkage technology is used to compensate for the internal stress of the material to ensure one-time forming of complex holes.

Cost optimization: Compared with laser cutting, wire cutting processing costs are reduced by 30%, and there is no heat-affected zone, which is suitable for mass production.

Extended application of spark wire cutting in environmental protection equipment

In addition to the catalytic converter housing, Zhikai CNC's technology can also cover the following key components:

1. Activated carbon adsorption bed frame: The honeycomb activated carbon bracket requires high-precision grid cutting, and wire cutting can avoid micro cracks caused by traditional stamping.

2. Heat exchanger fin assembly: 0.5mm thick stainless steel fins are processed with micro-hole arrays, with an accuracy of ≤ ±0.00 3 mm, to improve heat exchange efficiency.

3. RTO equipment valve sealing surface: complex curved surface processing of carbide sealing ring, surface roughness Ra ≤ 0.7-1.4 μm, extending the life of the equipment.
