The contemporary level of pipe rolling technology makes it possible to manufacture line pipes of strength class K42–K65 in corrosion- and cold-resistant versions. Pipes of this type are intended for building oil and gas pipelines that are used for developing fields, including those in the Far North. Avoidance of the main defects of both steel smelting and pipe rolling origin, revealed during pipe...
This article presents results of a study of the structural and physical inhomogeneity of an ingot used to produce rolled sections. The temperature of the outside surface of the ingot is measured as the ingot solidifies in the ingot mold and the thermal efficiency of the hot top is calculated. The data that are obtained show that the ingot must be modernized in order for it to be used to obtain large...
