FIELD: metallurgy.
SUBSTANCE: this pipe-rolling unit has section for store and preparation of forged billets, cast billets, ESR ingots-billets and ESR hollow ingots-billets for rolling. It comprises furnaces to heat said ingots-billets to ductility temperature. Roll table is used to delivers said forged ingots and ESR ingots-billets to helical rolling mills. Besides, it comprises plants for out-of-mill mandrel fitting, two transfer trucks to carry sleeves with mandrels to Pilger mills, two Pilger mills and other equipment. This plant is provided with section for preparation of process tools including two machines for production and control of geometrical sizes of Pilger rolls with body diameters of 975 to 1100 mm and 1125 to 1250 mm Two machines are used for surfacing of Pilger roll working parts by "30Х25Н16Г7"-grade wire. Lathe is used to produce mandrels, their diameter making 258-580 mm and while length approximates to 5.5 m.
EFFECT: higher precision of sizes, high-quality pipes and process efficiency.
