Quenching Pool

The leaf spring quenching furnace is usually used in conjunction with a heating furnace. After the workpiece is heated to the austenitizing temperature in the heating furnace, it is quickly transferred to the quenching furnace for cooling. The core of the quenching furnace is the circulation system and temperature control system of the quenching medium. The temperature of the workpiece is sharply reduced through liquid or gaseous medium to form martensite or bainite structure and improve the hardness of the steel.

Trough quenching furnace
After the workpiece enters the furnace through a manipulator or a conveyor belt, it is directly quenched into the quenching medium in the trough. It has a simple structure and is suitable for small and medium-sized leaf spring production lines.

Continuous quenching furnace
It forms an automatic production line, seamlessly connected with the heating furnace and tempering furnace, to achieve continuous and streamlined operation, suitable for large-scale automated production.

The leaf spring quenching furnace usually includes the following parts:
Furnace structure:

made of high temperature resistant and corrosion resistant materials to ensure the durability of the equipment;

Quenching medium tank:

size and spraying method are designed according to cooling requirements;

Circulation and cooling system:

maintain uniform temperature of the medium to prevent overheating or local overcooling;
 

Transmission system:

automatic conveying, positioning, and transportation of workpieces;
 

Electrical control system:

full monitoring and automatic control of temperature, time, liquid level, flow, etc.

Uniform cooling:

Through spraying, circulation or stirring design, all parts of the workpiece can be cooled simultaneously to prevent thermal stress concentration;
 

High control accuracy:

The automated control system ensures accurate quenching time and temperature, improving product consistency;
 

High production efficiency:

Especially the continuous quenching furnace, which saves man-hours and improves batch production capacity;
 

Safety and environmental protection:

The sealed structure and new environmentally friendly quenching liquid effectively prevent safety hazards such as oil smoke and fire;
 

Strong adaptability:

It can handle leaf springs of various specifications and models, and is suitable for multi-variety mixed flow production mode.
