Description
Summary:Results are provided for a study of the effect of barrel-shaped and bowl-shaped working rollers of a screw rolling piercing mill with guide bars of a 50–200 pipe rolling unit. By using a fundamentally new concept for describing the wear mechanism of a roller working surface, a dependence is revealed for worn part volume on amount of rolled continuously-cast and hot-rolled billets 90–260 mm in diameter. The level of material wear durability and working roller loss, restored by hard facing with flux-cored wire grade 18KhGSA in relation to amount of pierced billets, are established.
