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-C (Diamond 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 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.

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.

RTK-B-38-30-14-16

(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.

RTK-G (Gratex Type)

RTK-H (Herringbone Type)

RTK-DB (Double Balance Type)

(Example of use) * Sintering process of powder metallurgy * For copper brazing process

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.

MESH BELT

Since the mesh of this belt with a large open area is made by small diameter wire, products are directly affected by washing, spraying, coating and heat transfer which enables effective processing. Unnecessary matter remaining after a process is easily removed by coarse mesh and the belt can be simply washed to maintain good sanitary conditions.

RTK-E: Reduced diagram

(Example of use) * For food processing

Mesh belt of this type has been designed to especially fight dehydration. Twisted wires are used on the vertical wires to provide the belt with flexibility so as to withstand rollers of small diameter.Herringbone weaving is employed to prevent the belt from meandering and the horizontal wires are processed with a stop function to prevent mesh expansion.

(Example of use) * For fiber washing process

This type mesh belt is provided with rods and is most appropriate for light-weight product processing. The belt is manufactured for conveyors moving in a straight line or rotating at 90° or 180°.The smooth belt surface allows quiet driving, and the simple space structure of the belt permits easy maintenance to maintain sanitary conditions.These characteristics make the belt an excellent fit for the food industry where sanitation is a top priority.

(Example of use) * For cooling and freezing food products

Ancillary Processing

Depending on products to be transferred and their purposes, various means, such as mesh, pipe and angle, are available to enable reinforcement and elongation of the edge of the belt or flange configuration and stoppers of inclined conveyor.

Chain Combination

Belt drives available include friction, chain and sprocket drives, but other means are used for setting chains on the belt.Please advise us of your objectives and use so that we will be able to select chains from a first-class company and set them in the best way for you.

MESH BELTThe alloy of mesh belts used at high temperatures require precautions against the type of work, atmosphere, contaminants, and other such factors.

High nickel content alloy of the mesh belt used at high temperature deteriorates when it comes into contact with sulphur.

Zinc stearatePenetrates as the lubricant of powder metallurgy. High carbon content tends to make the alloy brittle when carburized

Lead and zincPenetrates 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.

Phosphate Damages high nickel content alloy in reducing atmosphere.

CopperDeposits 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.

Max. working temperatureName of alloy Characteristics

Acid resistance 1200°C

Strong material 870°C

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.

HA -214R

1150°CThis 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.

HA -230R

1150°CThis 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.

Inconel 600R

Inconel 601R

1150°CDue 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.
