Product Description
1. Working Procedures of the production line:
Steel bars are loaded at front of loading table and de-bundled at this stage;
Steel bars are prepared at loading table, waiting for transferred inside of furnace chamber;
Steel bars are horizontally heated inside of hardening furnace;
After heating process, steel bars will be discharged out of chamber from the other end of furnace door;  
Bars are transferred manually to the next operations for bending procedure before quenching;
Steel bars is transferred inside of quenching tank;(Steel bars are immerged in quenching water)
After quenching, steel bars are transferred at loading table at front of tempering furnace;
Steel bars are charged inside of tempering furnace chamber from one end of furnace door;
Steel bars are horizontally heated inside of tempering furnace;
After heating process, steel bars will be discharged out of furnace chamber from the other end of furnace door;
Air cooling process;
Steel bars are discharged out of furnace chamber,waiting for unloading.
2. Working cycle of the production line for Standard Cylinder : 18seconds/piece
3. Hardening Furnace:
3.1 Loading device and separating device: steel bars are loaded and separated at loading area, ensure constant loading process, steel bars are automatic loaded and aligned with sensors and stopper.
Loading table of the hardening furnace: it is designed at front charging door. Several pieces of steel bars are placed at loading table, thus to ensure the production line automatically running.
Loader and separator unit is made of formed steel, chain-conveyor, and pneumatic positioning device. Etc. 
  • Framework of loading and separating unit adopts 80*40*4 high quality square-shape steel pipe, continuously welded into robust structure. all components are fixed on the steel structure, and for steel bar storage, load, de-bundle, and separate.
  • Chain conveyor consists of 1-inch double conveying-chain, sprocket, bearing, driving shaft, and driving motor, which mainly used for separation and transmission of steel bars.  
  • Pneumatic cylinder positioning mechanism: it consists of cylinder, pneumatic components, and its pipeline, mainly for the positioning of steel bars and conveyor steel bars forward to waiting area.
3.2 Rated Temperature: ≤900-1000ºC
3.3 Effective dimension of working chamber:  4000×2500×250mm
3.4 Effective working station in side furnace chamber:  66 numbers.
3.5 Temperature Uniformity: ±10ºC
3.6 Energy Resource for the furnace: Natural gas,  capacity of burner: 55 Nm3/h,
Calorific value : 8400Kcal/Nm3
3.7 Heating Zone: 2 zones (1 zone for heating, and 1 zone for holding), temperature of each zone is separately controlled.
3.8 Transmission Device: walking-beam transmission unit adopts hydraulic driving method.
Both fixed beam and movable beam inside of furnace chamber are made of ZG3Cr24Ni7NRe heat resistance steel. Surface of fixed beam and movable beam are machined with saw-teeth slot, so to ensure steel bar can stable rest on them. 
Thickness of steel plate for movable-beam is 12mm, and thickness of steel plate for fixed beam is 25mm, upward and downward traveling stroke of movable beam is 80mm.  
Movable beam inside of chamber consists of one set of heat-resistance steel and one set of supporting column; supporting column across the furnace hearth and fixed with steel structure which located at bottom of furnace body. This special saw-teeth surface of walking beam ensures the steel bar been transferred from charging station to discharging station.
After installing of the supporting column, it should not be clashed with hole of bottom hearth; and the rectangle steel structure at bottom of furnace body should not interference with foundation. 
During heating procedure, steel bar can self-rotating, so to improve heating quality and temperature uniformity, ensure steel bar free from deformation, and black-spot. 
3.9 Furnace Shell:
Furnace wall, roof, and bottom are placed with 5mm steel plate. Column is made of 100x100mm square pipe.
Steel plates are seamless continuously welded; and steel plates are intermittent welded with column and formed steel. .Overall appearance of furnace body is compact, and neat.
Plate for install burners is made of 10mm steel.
Furnace shell quality is met the YJB300-95''Standards of fabrication, installation and commissioning of industrial furnace"
Furnace Lining
The standard alumina-silicate fiber modulars are fixed with furnace wall by special stainless anchors, thickness of lining is 320mm.
Fiber modular is stagger-fixed on roof, with compound structure, it has perfect anti-erosion ability and longer service life. Fiber modular on furnace wall are pre-compressed and fixed on wall via riveting anchors.  
Fabrication procedures of lining: firstly stainless steel riveting anchors are welded on furnace roof at interval space of 300mm×300mm, and then one layer of 20 mm alumina-silicate fiber blanket will be tiled closely with inner wall; after that, the 300mm×300mm×300mm pre-compressed modular will be inserted with anchors. This kind of structure provides a good insulation performance, improve environment, and reduce skin temperature of furnace body at ambient + ≤45ºC.
Lining design and construction meet GBJ211-87 industrial furnace manufacture, installation, commissioning, and acceptance criteria  and YJB300-95 "Industrial furnace masonry construction and acceptance of standards".
3.10 Charge/discharge method: end in & end out
3.11 Surface temperature of furnace wall: ambient temperature + ≤45ºC.
3.12 Bottom of furnace body is above ground at height of 200mm, thus to ensure a good ventilation.
