Reduce your maintenance costs
Castolin Eutectic helps you repair cracks, fractures and spalling in kiln tires, rail tracks, roller press, hammers or any damaged critical industry parts. Both as emergency and standard, planned repairs. We can either do the work on-site or in our 20 well-equipped Castolin Services workshops. For more than a century at the forefront of maintenance and repair, we are at your service with the largest and most experienced team of technical field consultants.
We fix cracks, breakage and leakages in your vital industry parts
Fatigue wear to the surface of a body is resulting from cyclical high load, pressure or shocks which weaken the metallurgical structure. The changing stresses resulting in either elastic or plastic deformation will provoke the formation of cracks under the surface. The fatigue wear mechanisms are limited to the surface, but any cracks generated can travel throughout the whole part if a certain stress is maintained and make it fail.
Fighting spalling, compression and deformation
Wear by impact is the result of successive high shock loads on the surface. If the surface is brittle it may readily fracture, but if it is tough it will yield by elastic or plastic deformation so that fracture will be avoided or at least postponed. The impacting material may be metallic or non-metallic, for example the mating members of a die in a press or the teeth of an excavator bucket striking rocks. Some of the effects of impact are: fatigue cracking, spalling, compression and deformation.
Repairs on-site and in our workshops
Frictional wear results from the sliding or rolling contact of one metal surface against another. To the naked eye, these surfaces may appear smooth and even highly polished but under a microscope, they show like "hills and valleys". Continual sliding contact at the interface causes microscopic welding and shearing of the "hills" of one or both surfaces. In addition, the harder crests will produce fresh valleys in the softer surfaces and the process will continue until the bearing surfaces wear down to the point where the clearance between them creates vibrations. If allowed to continue, this can lead to subsurface fatigue cracking, breakage or other serious failures.
