100kg/H Mesh Belt Furnace For Drywall Screws Quenching Hardening,
Tempering, Blackening
Brief Introduction
The production line is comprised of mesh belt quenching furnace,
quenching tank and elevator, post-cleaning machine,
hot air circulation tempering furnace, and electrical control
system.
Temperature
quenching furnace: 820~950℃, quenching tank: 60~80℃(the temperature
can be adjusted
automatically and manually ), tempering furnace≤650℃, cleaning
machine: 60~100℃(the temperature
can be adjusted automatically and manually ).

Equipment Specification of Each Unit
1. Mesh Belt Quenching Furnace
The quenching furnace is the main unit of the production line,
which is mainly composed of mesh belt
drive device, insulation material, heating device, atmosphere
supply control device and temperature control device.

2. Quenching oil tank and elevator
3. Post-cleaning machine (immersion type)
The post-cleaning machine has strong force spray device. The
workpiece is soaked in the cleaning liquid first,
and then it is strongly rinsed which makes the cleaning function
better. The post-cleaning machine has oil-water
separation design. The high and low design could separate the oil
that the workpiece brings into the cleaning tank.
The waste oil can be recycled to protect the environment. The
height difference between the cleaning machine
conveyor and the quenching furnace is lowered in order to prevent
collision when the workpiece falls, and
damping device is made on the collection hopper.
4. Hot air circulation tempering furnace
The tempering furnace adopts collective heating.The high power fan
generates the hot air circulation to
keep the furnace temperature uniform.
5. Electrical control system
The whole production line adopts the collective control system over
temperature, heating, and transmission.
The control system also has functions of audible and visual alarm,
thermal breakage alarm, and safety interlock.
All the transmission devices for the line can run clockwise and
anticlockwise. The control cabinet is front opening door.
The time reader can directly convert the frequency of the frequency
converter into the corresponding time,
which is convenient for process adjustment.
