Product Description
, Equipment Features and Process Description
1.1 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.

, Production Process Flow 
   Loading→ Transfer the cylinder to the loading conveyor of Quenching Furnace by overhead crane→ Quenching Furnace Door Open→ Convey the cylinder into the Quenching Furnace rapidly → Heating cylinder inside of Quenching Furnace(Meanwhile, cylinders moves slowly to prevent the roller from distortion and increase the uniformity of heating)→ Middle Door (Heat Insulation) Open → Cylinders transferred rapidly to the Holding zone of Quenching Furnace(Meanwhile, cylinders moves slowly to prevent the roller from distortion and increase the uniformity of holding)→ After process time is completed → Unloading Door Open and the cylinders are unloaded quickly → Door Close, Cylinders are transferred to the Side Unloading Conveyor of Quenching Tank→ Transfer cylinders 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 cylinders with Transfer car → Convey cylinders to loading conveyor of Tempering Furnace → Tempering Furnace Door Open → Transfer into tempering furnace for heating(working sequence, Takt time, control mode are all same as quenching furnace)→ Tempering Furnace Door Open after the process time is reached → Unloading rapidly → Cylinders are transferred to Unloading conveyor, cooling down and waiting for unloading → One cycle is completed, Waiting.
, Brief Equipment Introduction
1, Loading Conveyor 
 It is mainly designed for loading and rapid convey of steel cylinder, which consist of supporting bracket, roller, driving device, and control device.

Support Bracket: It is made of formed steel and steel plate and welded together, which provides a good appearance. Anchor plate is welded to the bottom of supporting bracket, which is fixed onto the embedded plate of foundation, as to ensure the reliability and safety. 
Roller Conveyor: It is made of 20# seamless steel tube (φ159×6mm). Positioning device is equipped with the roller to prevent the offset of steel cylinder and falling down during moving. Two ends of roller is made of 45# steel and machined into the shaft shape, and fixed onto the supporting bracket with the bearing. Locating bolts are equipped with the bearing to prevent the roller from deviating. 
Driving Device: It is driven by speed reducer through sprocket wheels and chains. The speed reducer is recommended to select MD Series helical gear redactor, made by Omiter, Shanghai.
