Wear-intensive industries trust us
Cored wires as welding consumables for build-up welding for wear protection purposes are used in different industries. The prerequisite for the use of cored wires is the possibility of being able to apply protective coatings via welding measures.
Saying nothing of the diverse areas of application, several main sectors can be identified where huge wear represents a key topic in day-to-day business and where cored wires are used.
Metal industry
In metallurgical plants, pig iron and steel are produced on an industrial scale from coke and iron ore. Large quantities of goods are produced, transported and handled – sometimes at high temperatures. This causes significant wear on equipment and tools.
Some examples of distinctive applications here are sinter crushers , rust bars, tilting tables, hot screens, slides and transfer points or even ventilators.
Over the years, we have developed an optimised cored wire material for each of these applications, which are now used successfully around the world.
Steel industry
Nowadays, continuous casting is one of the first process stages in the production of steel fittings. The liquid steel is cast into a chill mould so that the steel in its peripheral areas can be solidified and detached as a continuous strand. A multitude of rollers keep the strand in shape and support its feed rate. The regeneration of these rollers through build-up welding has now established itself as an efficient maintenance procedure. Our specialised and optimised solutions:

• Corthal® 356 N OA – cored wire electrode for double-layer build-up welding
• Corthal® 399 OA – cored wire electrode for economic single-layered application
• Corthal® GSI UP – cored wire electrode for sinter crusher rollers
• Copper-based alloy thalbronze 115 G – new development for thermally extremely stressed casters

In the further course of steel moulding production, a multitude of roller conveyors and guide rollers work under high pressure, and their regeneration and wear optimisation also fall within the scope of our tasks.
Cement industry
Clinker, the precursor to cement, is produced in highly efficient systems with very high throughput rates (up to 10,000 t/day). Limestone, sand and clay are generally used as raw materials. These are pre-shredded, burned into clinker in a rotary kiln and subsequently pulverised into finished cement with other additional components, such as gypsum. Particularly for the grinding of coarse siliceous clinker, our special cored wire electrodes, Corthal®600 TiC and Corthal® 760, have proven their worth.
Mining sector
Whether bucket wheel excavators, bucket chain excavators or surface miners, dimensions are huge in the mining industry. Economical mines and opencast mines move thousands of cubic metres a day, which places extremely high demands on the materials used. High wear and tear is discernible in all areas relating directly to production – starting with digging and scooping tools to conveyors (chutes, funnels and transfer points) and loading machines.
Power plants
The grinding of fossil fuels such as lignite and hard coal represents a focal point for abrasive wear in power plants. In particular, the grinding rollers and segment tables or bowls used in vertical roller mills are the most stressed components, in addition to piping, sifters and linings.
