Furnaces & heat treatments
As a large furnace manufacturer for
springs, hardware and fasteners in
China, Tonglu Sanli has focussed in
recent years on the development of
its overseas market to better serve its
customers around the world with good
quality at reasonable prices.
From small precision springs to big
automobile suspension and train
springs, Tonglu has developed a full
range of different sizes of hot wind
tempering furnaces, equipped with PID
intelligent temperature controller and
integrated auto-control system.
The temperature can be set freely
with a tolerance of ±3℃ under a 500º
hearth temperature environment,
installed with hot wind mixing device
which ensures the balanced and
precise hearth temperature, and thus
the quality of the parts to be treated is
guaranteed.
Smooth and stable auto-running of
stainless steel belt, stepless speed
regulation and auto speed control
allows an increase in productivity and
a decrease of labour intensity.
Brand-new structure, with all-fibre
furnace lining allows fast heating-up,
and reduction of electricity consum-
ption. This is a simple and secure
operation with no sodium nitrite
needed, and giving off much less
pollution.
Auto-feeding, auto-placement
and auto-discharging can be
offered based on the customers’
special requirements. This can
be applied to the carburising,
carbonitriding, quenching under
controlled atmosphere of self drilling
screws，nuts, bolts, wallboard nails,
chipboard screws, bolts and nuts for
furniture, wooden screws, dry wall
screws, machine screws, tapping
screws, springs, spring washers,
standard parts, bearings, gearing
chains, automobile parts, knitting
devices and hardware.
Perfect temperature distribution allows
the quality of the treated pieces to be
uniform and reliable.
Together with the feeding machine,
cleaning machine, quenching tank,
tempering furnace, blackening tank
and drying furnace, an automatic
production line can be quickly set up.
With dozens of patents in furnace
design, Tonglu continuously sticks
to its principal objective of
environmental protection by using
responsibly the refractories, and
special designs to prevent the
maximum loss of energy.
To perfect its product range in the
industry, Tonglu manufactures at the
same time the grinding machines,
grinding wheels, chamfering machines
and dust collectors.

Experience
counts at FIB
Present in 70 countries world-
wide, FIB Belgium is experienced
in the framework of equipment for
heat treatment of steel wires such
as pit, bell and continuous heat/
galvanising treatment lines.
The company has introduced
several new technologies for the
heat treatment of wires and small
strips. The new austenitising and
annealing furnace technology
IMFLEX was introduced two years
ago and has demonstrated its
capacity to decrease the carbon
footprint by 27 per cent.
Regarding steel wire galvanising
lines, FIB also introduced its
ZinXaver technology that allows
decreasing the length of the
galvanising bath by 30 per cent.
