Wear reduction in the steel industry
Steel industry is a full-continuum business – wear reduction prevents intermediate stops
Wivé Techniek supports wear reduction in the steel industry to prevent interim production stops. This is a challenge, because if there is one place where brute force is used, it is in the steel industry. It is a highly mechanical process. Huge earth movers dig into mountains of ore and coal, trucks bring these raw materials to silos, for transit via conveyor belts. Further along in the process, molten steel flows through chutes and red-hot sinter chunks are pulverized and then screened. Wear occurs at each stage of this full-continuous process. Some examples of measures against this wear:
Transportation of raw material and waste streams
The excavation buckets in the port of the steel company are made of two-sided wear-resistant cast steel, while the teeth, which suffer extra, are welded on with extremely hard armor wire. In the further transport of raw materials, gases and hot ashes, we use products such as wear-resistant tiles made of melt basalt, ceramic plates with zirconium or aluminum oxide, welded-on plates, natural rubber and extremely impact-resistant overflow or impact plates (Abresist, Kalcor, Kalocer, Kalcret, WearProtect WMW, Kalflex and Kalimpact). For fans, diagonally welded-on armor plate (Wearprotect WMW) is very successful.
Breaking and screening of sinters
In the sinter crusher, we apply heat-resistant welded-on materials, specifically wear-resistant welding wire or wear electrodes (WearProtect LTM program). We can wear-harden the heads of the crusher with tungsten, or Tungsten Carbide Overlay (WearProtect TCO), while we re-weld grid beams with wear-resistant welding wire. Furthermore, hard-welded plates are also used in the crushers. The sinter is sieved with sieves made of welded-on plates or wear-resistant cast steel (WearProtect WMC. For the hot screen (blind screen), wear-resistant high-temperature mortar (Kalcret) extends the tool life.
Interested in stand time extension?
In a full-continuum company like Holland’s largest steelmaker, the furnaces must be running and the steel must be flowing. 24 hours a day. You want to avoid an interim production stop at all costs. Wivé Techniek’s solutions help you do that. Would you like to know how we can also offer your company more continuity? Get in touch with us!
