Restoration and alloying of working bodies of earth-moving machinery

During the operation of road-building and earth-moving machinery, their working bodies are subjected to greatest wear, in particular: crowns rippers, blades dumps, teeth excavator buckets. The limiting state parts is characterized by a 2535 % loss mass worn elements that have direct contact with ground. Rejected during repair sent for recycling or restoration. service life some most loaded when heavy soils several hours. need earthmoving equipment from enterprises involved road construction quarrying Far East region measured tens thousands pieces per year. Replenishment stocks wear makes it necessary implement complex logistics schemes due remoteness facilities centers production parts, always accompanied significant costs. Therefore, problem restoring strengthening rippers buckets very relevant. Various industrial scientific organizations been solving this long time, quite good results direction were obtained after number developments at E.O. Paton Electric Welding Institute method electroslag facing (ESF). Based on method, various technological processes restoration massive created. use ESF allows not only restore but also obtain corresponding design requirements improved functional properties. These, vehicles, will increase durability. paper considers possibility vehicles using ore concentrates mined as alloying additives.
