MESH BELT
RTK-G (Gratex Type)
RTK-C (Diamond Type)
This type mesh belt can use the thickest wire diameter
and provides the highest tension. Smooth belt surface is
appropriate for transferring unstable items. The parts of
highest strength can be used for reinforcing the edge and
a net-type flange can be easily installed.
RTK-H (Herringbone Type)
This mesh belt has various advantages, such as the large
open areas, less heat loss in the heat treatment process,
and the low cost because of the light weight. For use
without chain, the belt functions ideally by alternately
combining the twisting direction of spiral wires at defined
intervals.
RTK-B (Balance Type)
The herringbone mesh belt can be processed with the
smallest meshes, and the belt surface pressure in the
pressing process provides the maximum force compared
to other mesh belts. The herringbone mesh belt with
smooth surface withstands tension, making it appropriate
for chemical treatment of fibrous products and
transferring small items. The net-type flange can be
installed.
The balance type mesh belt is structured mainly to
prevent the belt from creeping to one side on the drive
pulley. The balance type belt is characterized by this belt
structure and relatively high tension strength.
RTK-H-4-53-104-16-18
RTK-B-38-30-14-16
RTK-DB (Double Balance Type)
The double balance mesh belt closely resembles the
balance mesh belt and the combination of intersected
right hand and left hand spiral wires of the belt itself
prevents meandering. The connecting rod is crimped for
belts with larger meshes and is formed in a straight line
for belts with smaller meshes. Various type of mesh from
25mm to 1.7mm are available and the net-type flange
can be installed.
(Example of use) * For slow cooling and baking process of glass and
ceramic works
* For food processing
RTK-RR (Rod Reinforced Type)
Spiral wires are weaved together and structured to
reinforce the central intersection of the spiral wires
through the horizontal wire rod. As a result, weaved
meshes form two stable triangles, and the rod is
gradually bent to reinforce the belt edge, thereby
demonstrating the effect while working at high
temperature. The belt manufactured with the optimum
alloy can be used for high temperatures of up to 1200°C.
(Example of use) * Sintering process of powder metallurgy
* For copper brazing process

precautions against the type of work, atmosphere,
contaminants, and other such factors. The TWC alloy

When selecting alloys, checking the compatibility with contaminants present in the furnace is important.
Characteristics
Recommended metal
900°C or more Tailoy R -1
Sulphur
High nickel content alloy of the mesh belt used at high temperature deteriorates
when it comes into contact with sulphur.
Zinc stearate
Penetrates as the lubricant of powder metallurgy. High carbon content tends to
make the alloy brittle when carburized
Tailoy -5
Lead and zinc
Penetrates as the binder of powder metallurgy and zinc stearate of lead or zinc.
Corrosive action of lead and zinc is more serious than carburization of zinc stearte.
Tailoy -3
Damages high nickel content alloy in reducing atmosphere.
Tailoy -3
Deposits on the belt surface during brazing or sintering of copper-base powder.
Penetrates into the microstructure of the belt composing alloy and causes earlier
belt damage. Treatment to prevent oxidation is also effective.

Characteristics
Ni base alloy with excellent acid resistance at high temperature up to 1200°C. This new alloy
demonstrates excellent acid resistance because the alloy is protected by both Cr203 coating and strong
Al203. Good high temperature corrosion resistance is demonstrated even in a carburization and high
temperature atmosphere that includes chlorine.
1150°C
This alloy is Ni-Cr and W-Mo alloy and characterized by good acid resistance up to 1150°C, high
strength at high temperature, excellent stability after long hours of heating and good nitriding
resistance.
1150°C
This alloy is a standard material that can be used in violent
corrosive environments at high temperatures. In addition to excellent corrosion and acid resistance,
this alloy provides ideally balanced high strength and workability.
1150°C
Due to the high chromium content (normally 23%), Inconel 601 demonstrates acid resistance,
carburizing resistance and sulfide penetration resistance. Acid resistance is strengthened further by
aluminum and nickel.
