Continuous Mesh-belt Furnace
(Heating, Quenching, Carburizing, Carbonitriding and Tempering)
As a leading manufacturer of continuous mesh belt furnaces (also known as conveyor belt furnaces), our mesh-belt furnaces are customized according to special working conditions and parameters, making them the right equipment for quenching, carburizing, carbonitriding and subsequent tempering during medium temperature heating. The conveyor belt furnaces are also used for bright quenching, thin-layer carburizing and carbonitriding in shielding gases for mass-produced small and medium sized parts such as fasteners, chains, bearings, small weapons, hardware tools, elastic components, sewing machines, bicycle parts, automobile parts, motorcycle parts and more.
Features
- Continuous production, stepless speed regulation, easy process parameter control
- Smooth mesh belt running with no deformation
- Muffle furnace with an excellent sealing performance, controllable gas consumption saves energy
- Different preparation atmospheres or instillation atmospheres are used for bright quenching, thin layer carburizing or carbonitriding;
- Quenching tanks with optional quenching media including water, oil and molten salt are available for a variety of processes
- Overall process control with high automation accuracy
- PID temperature adjustment with high control precision
- Clean working environment.
Working principle
- Water, oil or molten salt are chosen as the quenching medium inside the quenching tank according to different steel grades.
- The mesh belt furnace is used for tempering below 650 ℃. Most of them are paired with the 1st two furnaces as continuous production units.
- Traditionally, there is a mesh belt cleaning machine located between the quenching furnace and the tempering furnace inside the mesh-belt furnace, though this is optional upon request. A washing machine and feeding machine can be equipped before the quenching furnace, and a cooling tank can be installed after the tempering furnace.
