When maintenance managers face continuous challenges with premature chain wear in high-temperature and abrasive environments, the features of the 216W chain offer a tangible answer to these problems.<\/p>\n<p>Especially in metal refining, the steel industry and copper smelters, where operating temperatures can reach up to 400\u00b0C, the lifespan of ordinary chains often falls short of expectations. <a href=\"https:\/\/kopar.fi\/en\/forged-conveyor-chains\/\">Discover forged link conveyor chains<\/a>, which have been developed to meet precisely these challenges.<\/p>\n<h2>What makes a 216W chain more durable than standard chains?<\/h2>\n<p>The 216W chain is made from boron steel (27MnCrB5), which retains its mechanical properties at high temperatures significantly better than standard manganese steel. At room temperature, the surface hardness of boron steel is approximately 30 % higher than that of manganese steel, and the difference increases to as much as 70 % at high temperatures.<\/p>\n<p>In addition to the choice of materials, the 216W chain has a more robust construction than the commonly used 142V chain. A larger cross-sectional area means higher tensile strength and better resistance to tensile loads. Whilst the 142V chain has a nominal tensile strength of 520, the 216W chain offers a tensile strength of 750, which is a 44% improvement.<\/p>\n<p>The special characteristic of boron steel is its behaviour during heat treatment. Unlike manganese steel, which only hardens on its surface, boron steel hardens almost all the way through. This makes the chain links tough and exceptionally resistant to wear. The hardness of the chain link does not change with surface wear, ensuring consistent performance throughout its service life.<\/p>\n<h2>How much longer will the 216W chain last in use?<\/h2>\n<p>The 216W chain typically lasts at least twice as long compared to a standard manganese chain in demanding operating conditions. The service life depends on the process and the properties of the material being transported, but a significant improvement is consistently observed, especially at high temperatures.<\/p>\n<p>The extended lifespan is based on several factors. Firstly, the higher temperature resistance of boron steel allows for continuous use at temperatures of 300\u2013400 \u00b0C, whereas the maximum operating temperature for normal manganese chain is around 200 \u00b0C. This is a critical difference in applications within foundries and metallurgical processes.<\/p>\n<p>Secondly, the higher breaking strength of the 216W chain offers a better safety margin under shock loading. When large material accumulations or load peaks caused by thermal shock occur in the process, the sturdier construction better withstands sudden stresses without permanent deformation.<\/p>\n<p>Thirdly, the even wear behaviour of boron steel means that the chain's performance remains stable throughout its entire service life. In manganese steel, the decrease in surface hardness with wear accelerates the wear process, whereas this phenomenon does not occur to the same extent in boron steel.<\/p>\n<h2>When is the choice of a 216W power supply most advantageous?<\/h2>\n<p>The 216W chain is the most cost-effective choice when the operating temperature exceeds 250\u00b0C, the process involves shock loads, or the service life of current chains is shorter than expected. Particularly in waste heat recovery boilers in smelters, gas cooling boilers, and drag conveyors in metallurgical processes, the 216W chain offers the best cost-efficiency.<\/p>\n<p>The profitability of an investment should be assessed as a whole. Although the 216W chain is more expensive to purchase than a standard chain, longer replacement intervals significantly reduce maintenance costs. Replacing a chain often requires stopping the process, which causes production losses. When the replacement interval doubles, these indirect costs are also halved.<\/p>\n<p>The 216W chain is particularly profitable in applications where:<\/p>\n<ul>\n<li>The continuous operating temperature is 250\u2013400\u00b0C<\/li>\n<li>The material being transported contains abrasive particles<\/li>\n<li>Large accumulations of material occur in the process<\/li>\n<li>Stopping production for a chain change is particularly expensive<\/li>\n<li>The lifespan of current chains falls short of expectations<\/li>\n<\/ul>\n<p>Instead, for lighter applications where the temperature remains below 200\u00b0C and no particular wear challenges arise, a basic solution may be sufficient and more cost-effective.<\/p>\n<p>From a maintenance manager's perspective, selecting the 216W chain is a strategic decision that impacts long-term costs and process reliability. <a href=\"https:\/\/kopar.fi\/en\/contact\/\">Contact us<\/a> to assess whether the 216W chain is suitable for your specific process and how it can improve your operational efficiency.<\/p>","protected":false},"excerpt":{"rendered":"<p>The 216W chain lasts twice as long at high temperatures.
