Well type Annealing Furnace for Nuts Parameter
Annealing Furnace Main Applications
Long Bars: Steel bars hung in the pit, annealed without bending. Comes out straight.
Bolts: Bolt blanks softened for heading. Surface clean, no scale.
Wire Rod: Coils hung on the hearth. Heat reaches the center, anneal is even.
Bearing Stock: Bars and tubes with low decarb. Cut and machine after.
Spring Wire: High-carbon wire softened so it coils without cracking.
Top Load: Crane lowers a basket in. No bending, no hand carry.
Bars Hang: Vertical hang keeps long parts from sagging - a problem in box furnaces.
Methanol Gas: Methanol turns to CO/H2/N2 in the heat. Oxygen leaves, scale doesn't form.
Fiber Lid: Light lid holds heat, uses less power each run.
Fan Heat: Fan moves hot gas through the load. No cold spots on a full charge.
Quick Cool: Fast fan drops temp. More batches a day.
Simple Build: Few moving parts. Stays up, cheap to keep.
Technical Features
Clean Parts, No Decarb: Annealed parts stay clean, no scale, almost no decarb - good spheroidizing, stable quality.
Ceramic Fiber Lid: Furnace lid uses ceramic fiber blanket - good insulation, light body, low power use.
Layered Bottom Insulation: Furnace bottom has layered insulation cotton + firebrick - holds heat well.
Light Inner Barrel: Light inner barrel - lasts long, less maintenance.
Even Heat by Convection: Convection heating - load is even temperature inside and out, no hot or cold spots.
Fast Cooling Fan: Big high-speed cooling fan - heats fast, saves time and power.
How Does a Annealing Furnace Work?
1.Crane lowers the load into the furnace
2.Seal the chamber, feed methanol decomposition gas + nitrogen to push out oxygen
3.Electric heat, fan blows the hot gas evenly
4.Force-cool, lift the lid, crane pulls the load out
FAQ
1.What materials can it anneal?
Carbon steel, alloy steel, bearing steel, stainless wire rod, and bolt blanks. Mostly spheroidizing and softening anneal.
2.Is well-type the same as pit-type?
Same machine. Well-type means a round chamber loaded from the top; pit-type means it sits below floor level.
3. Why methanol decomposition gas?
A: It breaks down into CO/H₂/N₂, pushes out oxygen and controls decarb - good for fasteners and bearing steel.
