CNG Cylinders Hardening Line
CNG Cylinders Hardening Line:
● The line is comprised of three main parts:
1- Hardening furnace
2- Automatic quenching tank
3- Tempering furnace
● Capable of charging CNG cylinders in different sizes and weights
● Continuous with adjustable motion pace
● Gas fired heating system
● No direct contact of flame with the surface of treated parts
Hardening Furnace
● Gas fired heating system
● Continuous walking beam type
● Maximum temperature: 1100°C
● With preheating and soaking zones
● Low surface oxidation
● Automatic cylinder charging and discharging tables
Automatic Quenching Tank
● Automatic immersion and extraction of the cylinders
● Affording various quenching methods
● Equipped with the cooling and heating systems
● Suitable agitation inside the quenching tank
Tempering Furnace
● Gas-fired heating system
● Continuous movement with conveyor or walking beam systems
● Hot air circulation system to reach to the best thermal uniformity
● Maximum operating temperature of 750°C
● Including preheating and soaking zones with excellent thermal
uniformity
● No direct flame contact with treated parts
PLC-controlled Automation & Monitoring System:
Capabilities of this system are:
● Temperature control and display of actual and set temperatures
graphs in each zone
● Display of burners status
● Display of temperature graphs for each zone (Temperature-Time graph)
● Data recording such as temperature, pressure, ...
● Display of doors status
● Display of system motion performance
● Display of motor fans mode (On/Off)
● Display of PLC operation option (Manual/Automatic)
● Alarming in cases of air pressure drop, gas pressure
drop/rise, temperature rise in each zone, burner
turn off and PLC malfunction
