AI Technical Summary
The gas path structure of existing heat treatment furnaces results in uneven gas distribution, which affects the quality of workpiece processing, and has poor versatility, making it unable to adapt to complex process requirements.
By adopting a biomimetic branch pipe and micropore design, combined with a gas diversion valve, a one-way valve and a flow sensor, independent control and monitoring of the gas can be achieved, ensuring uniform distribution and independent regulation of the gas in the heat treatment furnace.
This achieves uniform gas distribution within the heat treatment furnace, reduces operational complexity, improves the uniformity and pass rate of workpiece processing, and reduces the risk of production interruption.
