RG-120-9 Roller-type Tiltable Nut Carburizing Furnace Automatic
Control
A. Nut Carburizing Furnace Applications
RG120-9 tiltable roller resistance furnace is mainly used for gas
carburizing,gas carbonitriding and bright quenching& heating small
parts with different shape,such as steel balls,bushins,pins,tapping
screws,standard parts,chains are made of high-speed tool steel,die
steel,martensitic stainless steel,titanium alloy and such metal
materials.
B. Nut Carburizing Furnace Structure
This furnace composed of a furnace body, rotating mechanism,
tilting device, control system, drip gas supply system and so on.
The advantage of this series of products is that the heat treatment
quality of the parts is uniform, can be used in one furnace, high
productivity, easy operation and maintenance.
- Rotary carburizing heat treatment furnace shell is welded by sheet steel and sectional steel profile steel.
- Furnace lining adopting the super light weight high strength 0.6/cm³beads
energy-saving refractory brick, using the high alumina silicate
fiber for heat preservation, super energy-saving structure ,energy-saving effect is excellent.
- Using the Ocr21Ai6Nb resistance wire as the heating element, long service life.
- Electric rotary furnace pot is made of 310S (Cr25Ni20) , one end is supported by bearing support outside the furnace body,
using the electromotor and reduction gears to realize the
transmission, making the furnace pot to rotate slowly, meanwhile,
the workpiece will be heated uniformly as the furnace pot rotation,
the workpiece color and lustre is consistent after heat treatment.
The other end is feed inlet, supported by 2 pieces of idler wheel, when feeding, shake speed transmission on the furnace tilting supporting bracket
by hand, the furnace feed inlet will incline upward 20°, convenient
for feeding, when discharging, incline downward 40 ° , then
workpiece will be poured out.
