Hardening medium:Â Oil quenching
Products:Â Standard fastenersThis fully automated heat treatment line is designed for efficient and precise processing of standard fasteners. It consists of multiple key components including a Lifting Feeding Machine, Weighting Device, Pre-Water Immersion Washer, Vibration Spreader, No-Muffle Carrier Roller Wire-Mesh Belt Controlled Atmosphere Hardening Furnace, Oil-quenching tank, Horizontal Washer, Wire-mesh belt Tempering Furnace, Cooling Tank, and an Electric Control Cabinet. The system integrates advanced Japanese furnace technology and follows industry standards for resistance furnaces. Key components are imported, ensuring high-quality manufacturing and assembly that meets domestic industry benchmarks. This production line is built with state-of-the-art techniques, covering material loading, pre-washing, distribution, hardening, cooling, post-washing, tempering, and final cooling. The main furnace uses low-voltage, high-current transformers to extend the life of the radiant tubes and simplify maintenance. The wire mesh belt features synchronized rotating rollers, reducing tension during operation and increasing durability.
