Core principles and working processes
This equipment is based on the theory of metal phase transformation and achieves heat treatment through the following steps:
Youdaoplaceholder0 Heating and austenitizing : The workpiece is evenly spread on the high-temperature resistant mesh belt and sent into the heating furnace at a constant speed (the temperature is usually 800-1000℃), and a uniform austenite structure is formed under the PID temperature control system.
Quenching treatment : The heated workpiece enters the quenching tank, and high-pressure nozzles spray quenching medium (oil, water or polymer) to achieve rapid cooling, transforming austenite into martensite and enhancing surface hardness.
Continuous drive and atmosphere control : The mesh belt is driven by a variable frequency speed control motor, and the speed is adjustable; Protective gas (such as methanol) is introduced into the furnace to prevent oxidation, and the carbon potential control system ensures process stability.
Key components and advantages
The main module : it includes an automatic feeding machine, carburizing furnace, quenching oil tank, cleaning machine and tempering furnace, among which the carburizing furnace is equipped with a built-in mesh belt drive device and heating elements.
Technical advantages : Multi-zone temperature control eliminates temperature differences, PLC automatic control enhances efficiency, suitable for batch processing of small parts such as bearings and fasteners, featuring high efficiency, energy conservation and stable quality.
