Investigation of the temperature factor on the formation of a strip surface micro-relief during warm rolling

Kulik T. A. Investigation of the temperature factor on formation a strip surface micro-relief during warm rolling
 The is studied as that affects strip, which was rolled with heat. Various schemes for heating to required are considered. A mathematical model distribution over thickness and along length deformation zone obtained. height not same. Our studies have shown scheme better when heater inside roll. This because it gives smaller spread zone. That is, you can use factor. roughness rolling influenced by several factors. If we consider process final tempering, then one main factors temperature. We how printability coefficient from rolls metal. Experiments were carried out confirm results. experiment consisted in indentation single indenter into metal sample. Indenters various shapes used, similar shape micro-protrusions real relief work rolls. sample heated different temperatures drying box, depth its measured. Experimental an almost linear dependence penetration temperature, form observed all forms indenter, although intensity. So, confidently say be used control parameters needed. To do this, at stage technological chain rolling, temper desired micro-relief,
