Forever’s long bar induction hardening and tempering furnace has significant technological and market advantages in the field of metal material processing, especially in the heat treatment process of long rods (such as bearing steel, alloy structural steel, titanium alloy, etc.).
Overview of Equipment Core Advantages
Specific manifestations of advantageous dimensions
Uniformity control: Temperature control accuracy ± 1 ℃, uniform flow of quenching medium, avoiding deformation of long bars or uneven hardness.
Energy saving and efficient: With a waste heat recovery system and intelligent combustion control, energy consumption is reduced by 20% -30% compared to traditional furnace types.
High degree of automation: Integrated robotic arm loading and unloading, PLC full process monitoring, supporting unmanned production.
Strong adaptability: steel bar induction heat treatment machine can handle rods with a diameter of Φ 20-300mm and a length of ≤ 12m, and is compatible with various alloy materials (such as 42CrMo, GCr15, etc.).
Environmental compliance: Low NOx combustion technology+exhaust gas treatment system, meeting strict environmental standards (such as EU CE and Chinese GB standards).
Analysis of Key Technological Highlights - Long bar hardening and tempering machine
(1) Precise temperature control and quenching system
Multi zone independent temperature control:
The furnace body is heated in sections (preheating, austenitizing, and uniform temperature zone), and the temperature in each zone can be independently adjusted to ensure the uniformity of axial and radial temperature of the long rod.
Optimization of quenching medium: High pressure spray quenching (water, oil or polymer medium) is used with adjustable flow rate to avoid cracking or soft spots caused by uneven cooling rate.
Rapid ventilation technology: dynamic circulation of furnace atmosphere (such as nitrogen, methanol cracking gas) to reduce oxidation and decarbonization.
(2) Energy saving design
Waste heat recovery: The heat from the quenching tank is recovered through a heat exchanger and used to preheat the combustion air or clean water for heating.
Intelligent combustion control: Proportional adjustment of gas valve+oxygen content feedback to achieve dynamic optimization of air-fuel ratio and reduce gas waste.
(3) Automation and Intelligence
Mechanical arm loading and unloading: linked with the front and rear processes (such as sawing and straightening) to achieve fully automatic assembly line operation.
Digital twin monitoring: Real time collection of temperature, pressure, deformation and other data through sensors, AI algorithms predict process deviations and automatically correct them.
The core competitiveness of Forever long rod quenching and tempering heat treatment furnace lies in high-precision temperature control, energy saving and high efficiency, and high automation, especially suitable for high-end manufacturing industries with strict requirements for quality stability.
