Coal-fired power generation facilities require that the pulverized coal is optimized for the plant. As such, many coal-fired plants crush and size the coal on site. While there are many different types of coal crushing systems, they are all subject to abrasive and impact wear that require surface treatments to maintain efficient operation.
Innovative Wear- and Impact-Resistant Materials
Weld overlay materials from Metco Joining & Cladding are different. We design our materials using computational design and test candidates to find the best option for our customers. This means that the material solutions available from Metco Joining & Cladding perform significantly better and last longer than traditional weld overlays, such as manganese steel, while being cost-effective and easier to apply.
Use wear solutions from Metco Joining and Cladding on all types of coal crushers, including:
Robust Material Solutions
The conventional solution — manganese steel weld alloys — are relatively soft and not highly abrasion resistant. Instead, novel materials from Metco Joining & Cladding, including our manganese steel composition, can be reliably applied using conventional welding equipment such as GMAW (Gas Metal Arc Welding). Overlays of our Manganese Steel composition offer a welded hardness of HRC 45 to 55 and a work-hardened hardness as high as HRC 65! It’s easy to understand how our composition will outperform conventional compositions.
