Automated Quenching Oil Tank with Cooling & Fume Purification | WDL-CH Model

Wuxi Wonderly Industry Equipment Co., Ltd. introduces the WDL-CH Automated Quenching Oil Tank, a high-performance, integrated system designed for precision and efficiency in the heat treatment of alloy spring steel components, particularly large coiled springs. This advanced quenching tank seamlessly integrates with automated production lines, offering a complete solution that encompasses infrared temperature measurement, stepping-type workpiece movement, closed-loop oil cooling, and a powerful fume purification system to ensure optimal quenching quality and a safe, environmentally compliant workshop environment.

The core function of the WDL-CH system is to provide controlled, rapid quenching for hot springs delivered by robot. An infrared thermometer first verifies each spring reaches the required temperature (≥780°C) before granting entry. Qualified springs are then smoothly received and rapidly submerged into the quenching oil by a dedicated lifting mechanism. The innovative stepping-type chain plate conveyor within the tank ensures precise, controlled movement and dwell time for uniform cooling. After quenching, springs are automatically transferred via a V-shaped hopper and conveyor system to the next stage, such as a tempering furnace.

Key to maintaining consistent results is the quenching oil temperature control system. A high-capacity closed-loop heat exchanger (Model BNL-80), with a cooling capacity of 550,000 kcal/h, ensures the oil bath temperature remains within a stable range of 20°C to 80°C, typically below 60°C for optimal process control. Furthermore, the integrated oil fume extraction and purification system actively captures and filters smoke and mist from the tank's inlet and outlet areas. Utilizing a two-stage electrostatic field principle, it effectively removes pollutants, deodorizes, and ensures exhaust meets environmental standards.

Key Technical Specifications:

Designed and manufactured by Wuxi Wonderly, the WDL-CH Quenching Tank is built with a robust 6mm thick Q235 steel plate construction for durability and leak prevention. Its automated logic control allows for seamless integration into smart factory setups, operating in automatic or manual modes. This system is the ideal choice for manufacturers seeking a reliable, high-throughput, and clean automated quenching solution that guarantees part quality, process repeatability, and a responsible manufacturing footprint.
