The Core Secret Of KTK's Edge Technology To Solve The Problem Of Sintering Furnace Mesh Belt Wear

In high-temperature sintering production sites, the mesh belt, as the core carrier for material transportation, its operational stability directly determines production efficiency and product quality. However, the problems encountered by most enterprises, such as premature scrapping of mesh belts and frequent shutdowns, often stem from the easily overlooked edge parts. These edges are not only the key contact surfaces that fit with the furnace guide rails, bearing the overall tensile force of the mesh belt, but also directly face side friction and impact from materials. Any design oversight can turn them into "stress concentration hotspots," triggering a chain of failures such as tearing, deformation, and wear.

Targeting the operational characteristics of different industries, we have developed and customized three mainstream edge treatment technologies and characteristic process solutions to fundamentally address edge wear pain points, providing stable and reliable transportation guarantees for various industries.

• Direct Welding: Dual Empowerment of High-Temperature Stability and Operational Convenience

The direct welding process forms an edge structure by directly welding the spiral wire and the force bone. With the advantage of easy disassembly, it greatly reduces the time cost of mesh belt installation and daily maintenance, becoming the basic preferred solution for many enterprises.

KTK has made breakthroughs in two dimensions: process optimization and welding environment control.

(1)In terms of welding technology, precise parameter control technology is adopted to create full and rounded weld structures, significantly improving connection strength. Even in extreme high-temperature conditions above 1100°C, it can effectively avoid the risk of weld cracking.

(2)In the selection of welding gas, high-purity and stable argon is used as the protective gas. It not only isolates air to form dense welds, preventing weld oxidation and failure at high temperatures, but also maintains precise arc fusion through stable gas flow, reducing process defects such as welding deviation and uneven penetration, thereby minimizing fracture risks from the source.

• Hooked Edges: A "Hardcore" Solution for Anti-Dispersion in Temperature-Varying Scenarios

In production scenarios such as powder metallurgy with frequent temperature rises and falls, mesh belts are prone to deformation due to thermal expansion and contraction. Ordinary edge processes often suffer from loosening and tearing of spiral strips and cross bars, leading to premature scrapping of mesh belts. Kansai Metal Mesh's innovatively developed hook edge-locking process forms an "interlocking" integral structure, completely solving this industry pain point.

The core advantage of this process lies in "no loosening under deformation." The edge-locking structure and the main body of the mesh belt form a synchronous stress system, with tensile resistance increased by more than 30% compared to traditional processes. Even when the mesh belt deforms due to severe temperature changes, the edges can maintain a tight interlocking state without dispersion or failure.

Verified by on-site applications in multiple powder metallurgy enterprises, mesh belts adopting the hooked edge process have a service life extended by 50% compared to ordinary mesh belts under the same working conditions, effectively reducing equipment operation and maintenance costs.

• Baffle Edges: "Dual Protection" Against Leakage and Wear in Heavy-Load Scenarios

For heavy-load working conditions such as thick material layer sintering and large particle material transportation, mesh belt edges not only have to withstand stronger wear and impact but also need to solve production problems such as material side slipping, falling, and jamming.

KTK's baffle edge process, combining "structural design + precision welding," builds an all-round protection system, perfectly adapting to heavy-load requirements.

In terms of structural design, we customize baffles according to the sintering furnace size, workpiece characteristics, and material size. This ensures that the baffle height is sufficient to prevent materials from slipping and falling, while precisely controlling the thickness to avoid affecting the operational flexibility of the mesh belt. In the fixing process, a dual reinforcement method of cross bar perforation + argon arc welding is adopted. After the cross bar passes through the pre-reserved holes in the baffle, full welding is performed, making the baffle and cross bar form a rigid connection, directly enhancing the edge strength of the cross bar to bear the dual pressure of the baffle and materials.

This process places higher demands on the basic structure of the mesh belt. We ensure that the mesh belt body can bear dual loads and achieve stable operation through pre-control measures such as strictly controlling the spiral pitch tolerance of spiral strips and selecting cross bars with standard diameters.

• Characteristic Processes: Customed Solutions for Precision Scenarios

In addition to the three mainstream processes, Kansai Metal Mesh has also developed characteristic processes such as edge folding height and inserted U folding height for precision sintering scenarios such as electronic ceramics.

The edge folding height process enhances local edge rigidity through cross-sectional shape optimization such as U-shaped folding and wire-wound folding, meeting the special requirements of precision sintering for edge flatness and shape.

The inserted U folding height process adopts a composite process where U-shaped force bones are inserted before folding height treatment, increasing edge strength by 40% compared to traditional processes, adapting to customized scenarios with special requirements for edge load-bearing.

From high-temperature metallurgy to precision electronics, from powder metallurgy to new material research and development, Kansai Metal Mesh has always been guided by operational needs. Through continuous innovation and precise control of edge processes, we provide customized mesh belt solutions for customers in different industries.

Up to now, we have served more than 1,000 enterprises, helping customers effectively avoid edge wear problems and achieve dual improvements in production efficiency and product quality.
