Popis: | The mechnism of the salt phosphate lubricant ingress in zone of the tube deformation on a long cylindric mandrel was considered. Suggested mathematical model is based on the points of the hydrodynamic theory of lubrication. Data presented are concerned with a value of a salt lubricant layer thickness and friction factor between metal and mandrel at continuous hot rolling of tubes. Razmatran je mehanizam prodiranja soli fosfatnog maziva u zonu deformiranja cijevi valjanih na dugom cilindričnom trnu. Prijedlog matematičkog modela se osniva na hidrodinamičkoj teoriji podmazivanja. Podaci su prikazani vezano za vrijednosti debljine sloja podmazivanja i koeficijenta trenja između metala i trna pri toplom kontinuiranom valjanju cijevi. |
