Product Description

1. Equipment Purpose
This equipment is a roller-hearth type heat treatment production line for steel gas cylinder, which is mainly designed for heating, holding, quick quenching, tempering of various sized gas cylinders, as to achieve an automatic control from loading to unloading and meet the buyer’s process requirement. 

2.  Production Process Flow
   Loading→ Transfer the casting to the loading conveyor of Quenching Furnace by overhead crane→ Quenching Furnace Door Open→ Convey the castings into the Quenching Furnace rapidly → Heated casting inside of Quenching FurnaceMeanwhile, cylinders moves slowly to prevent the roller from distortion and increase the uniformity of heating→ Middle Door (Heat Insulation) Open → castings  transferred rapidly to the Holding zone of Quenching FurnaceMeanwhile, castings moves slowly to prevent the roller from distortion and increase the uniformity of holding→ After process time is completed → Unloading Door Open and the castings are unloaded quickly → Door Close, casting are transferred to the Side Unloading Conveyor of Quenching Tank→ Transfer casting into the Quenching tank for Quenching. Meanwhile, the transfer car moves up and down, as to uniform the quenching media and ensure the quenching quality → Lift up castings with Transfer car → Convey castings to loading conveyor of Tempering Furnace → Tempering Furnace Door Open → Transfer into tempering furnace for heatingworking sequence, Takt time, control mode are all same as quenching furnace→ Tempering Furnace Door Open after the process time is reached → Unloading rapidly → castings are transferred to Unloading conveyor, cooling down and waiting for unloading → One cycle is completed, Waiting
