| description | FIELD: metallurgy. ^ SUBSTANCE: tubes are made from steel containing the following components, wt %: carbon not more than 0.16, silicon 0.30-0.50, manganese 0.50-0.70, chrome 3.00-6.00, molybdenum 0.40-1.00, vanadium 0.04-0.10, niobium 0.04-0.10, aluminium 0.02-0.05, rare-earth metals 0.005-0.015, iron and inevitable impurities - the rest; flattening of tube wall is performed at temperature of 1050-900C; cooling in the air after flattening is performed up to temperature of 700-650C and reduction or calibration of diameter is performed at that temperature. ^ EFFECT: formation of steel structure which provides the stability of its characteristics throughout the length of manufactured tube. ^ 3 tbl, 2 dwg
Изобретение относится к области обработки коррозионно-стойких насосно-компрессорных труб. Трубы изготавливают из стали, содержащей, мас.%: углерод не более 0,16, кремний 0,30-0,50, марганец 0,50-0,70, хром 3,00-6,00, молибден 0,40-1,00, ванадий 0,04-0,10, ниобий 0,04-0,10, алюминий 0,02-0,05, РЗМ 0,005-0,015, железо и неизбежные примеси - остальное, раскатку стенки трубы ведут при температуре 1050-900°C, охлаждение на воздухе после раскатки осуществляют до температуры 700-650°C и при этой температуре проводят редуцирование или калибровку диаметра. Техническим результатом изобретения является формирование структуры стали, которая обеспечивает стабильность ее характеристик по длине изготовленной трубы. 3 табл., 2 ил. |
