Advanced Ceramics for Protection Against Wear and Corrosion

Wear and Corrosion Protection with ALOTEC®

ALOTEC® advanced ceramics is a modern material that meets the highest requirements even under difficult conditions such as wear, corrosion and high temperatures. Based on ALOTEC® advanced ceramics, CeramTec-ETEC has made a name for itself as one of the world's leading and largest suppliers of wear and corrosion protection solutions.

ALOTEC® is used, for example, in transport chutes and chutes, vibrating conveyor chutes, but also in drum mills, concrete mixers and distribution chutes as a large-area lining on the basis of custom-made plates and bricks. When transporting metallurgical coke, ALOTEC® linings achieve a service life that is around 12 times longer than alternatives made of steel. Enormous increases in service life are also achieved in granulation chutes for blast furnace slag or disc and double-shaft mixers.

Areas of Application

  • Chemicals industry
  • Food industry
  • Foundries
  • Mineral extraction and mineral processing
  • Paper and pulp manufacturing industry
  • Pharmaceutical industry
  • Power plants
  • Production and processing of cement and concrete
  • Recycling and waste processing
  • Steel mills

Cost Savings due to longer Service Life of the Plants

Material and application-specific designs make it possible to produce a variety of components with high dimensional accuracy. What’s more, ALOTEC® products in the form of steel and polymer composites help to open up new areas of application all the time.

CeramTec-ETEC develops, manufactures and assembles integrated system components and complete systems for different applications. Examples include cleaners/cyclones with ceramic/PU material combinations, which are significantly lighter than comparable products in ceramic/steel or pipes with ceramic linings.

Maximum Hardness

ALOTEC® advanced ceramics is the basis for protecting industrial equipment against wear and corrosion and offers the highest degree of hardness of all wear protection materials used today. The high homogeneity of ALOTEC® ceramics guarantees uniform, low abrasion.

Even in the high temperature range above 1,000°C, we are happy to apply our expertise to your wear challenges and offer you customised solutions.

ALOTEC® – Properties and Advantages

  • High hardness and wear resistance
  • Defined and uniformly low erosion
  • High temperature and corrosion resistance
  • Dimensional stability
  • Low specific weight

CeramTec-ETEC offers complete solutions with both its standard plates and blocks and its customer and project-specific ceramic components manufactured in various sizes, shapes and complexities and as composites with steel or polymers.

Versatility in Grinding, Mixing, Pumping, Pouring

Using ALOTEC® advanced ceramic in mills as mill feed enables short grinding cycles, iron-free grinding and – combined with high grinding capacities – maximum operation efficiency. Due to its chemical composition ALOTEC® is non-toxic and can therefore also be used in the pharmaceutical and food industries. ALOTEC® advanced ceramic is also ideal as wear protection for processes where high impact energy plays a role, e.g. for transfer hoppers, funnel tubes or skip cars for blast furnace feeding. In composites with other suitable materials such as polymers it can even be used in applications with extremely high impact energy.

ALOTEC® is used widely to protect pneumatic pipe systems from wear. Highly turbulent areas in particular, arcs, pipe necks, manifolds and inlet pipe ends often experience extreme wear. ALOTEC® achieves a service life up to 10 times that of steel in such applications. In addition to the assembly and supply of linings CeramTec-ETEC also offers complete parts (including ball valves) and steel-ceramic composite systems.

ALOTEC® advanced ceramic has proven itself in the transport of solids in corrosive media that can increase abrasion and erosion. Typical applications include conveying chutes for suspensions (for example raw coal), mixing tanks, pipe systems or screw conveyors and decanter screw centrifuges for discharging highly abrasive slurry. Ceramic composite systems are applied both for this and for other kinds of applications involving specific requirements in order to tap the full potential of ceramic materials (combined with rubber or PU, for example) and provide optimized solutions to our customers. Examples include flexible tube elements or drive rollers for conveyor belts.

Our Expertise for your Success

CeramTec site in Lohmar Germany

Service

Effective anti-wear starts with design that meets the application and material requirements based on an application-specific system analysis. It takes into account all the mechanical, thermal and corrosive loads of a system.

The experts at CeramTec-ETEC use this information to develop an economical solution with material recommendations for ceramic as well as its processing and assembly. One advantage of ceramic linings is that the individual ceramic parts do not need to be adjusted on site, which is both costly and time consuming. CeramTec-ETEC can take them in their unfired state and accurately adjust them accordingly. This CAD-based service delivers a detailed installation plan for time and cost-saving assembly, which the experts at CeramTec-ETEC also perform on request. The result is significantly lower downtime and longer maintenance and repair intervals for maximum efficiency!

Problem Solving by our Wear Protection Experts

The wear protection experts at CeramTec-ETEC deliver solutions in all application areas for the specific needs of individual customers in various industries. They focus on both the development, production and installation of wear linings for tanks and pipe systems as well as on complex ceramic components for machinery and equipment such as measuring and control devices, ball valves, hydrocyclones, bearings, nozzles, pitot tubes, lances or ceramic composite systems with steel, PU or rubber.

CeramTec-ETEC’s state-of-the-art production methods allow the company to design and make complex ceramic components for a wide range of applications, even in small quantities. Optimized integration into existing systems and composites with other materials such as steel and cast iron is generally key. Here as well, CeramTec-ETEC’s expertise is the basis for a variety of application and customer-specific developments in state-of-the-art wear and corrosion protection technology based on advanced ceramics.

Comprehensive customer consultation ensures long service life and maintenance intervals for maximum efficiency – all based on CeramTec-ETEC’s reliable and dimensionally accurate components manufactured within an ISO 9001 certified process at the company’s high-tech facilities in Lohmar, Germany.
