Abstract
Изобретение относится к металлургии. Слиток из конструкционной криогенной аустенитной высокопрочной коррозионностойкой свариваемой стали, содержащей углерод, хром, никель, марганец, молибден, кремний, азот, алюминий, железо и примеси, в качестве которых она содержит серу, фосфор, олово, свинец, висмут и мышьяк, отличающейся тем, что она дополнительно содержит медь и бор при следующем соотношении компонентов, мас.%: C - 0,05-0,07; Cr - 18,0-20,0; Ni - 5,0-7,0; Mn - 9,0-11,0; Mo - 1,8-2,2; Si - 0,25-0,35; N - 0,30-0,38; Cu - 0,6-1,4; B - от более 0,01 до 0,015; Al - 0,015-0,035; S≤0,0025; P≤0,015; Sn≤0,005; Pb≤0,005; Bi≤0,005; As≤0,005; Fe - остальное. Способ термодеформационной обработки слитка заключается в том, что осуществляют нагрев слитка до температуры 1250-1050°C, его ковку в заготовку с суммарной степенью деформации не менее 50%, охлаждение заготовки на воздухе, нагрев заготовки до температуры 1180-1080°C с последующей прокаткой с суммарной степенью обжатия не менее 40% и охлаждением на воздухе с получением проката, нагрев проката до температуры 1150-1080°C и заключительную прокатку в 2-3 прохода с суммарной степенью обжатия 30-80% и температурой окончания прокатки 1050-1080°C, после чего осуществляют ускоренное охлаждение со скоростью 20-100°C/с до комнатной температуры.The invention relates to metallurgy. An ingot made of structural cryogenic austenitic high-strength corrosion-resistant weldable steel containing carbon, chromium, nickel, manganese, molybdenum, silicon, nitrogen, aluminum, iron and impurities, in the capacity of which it contains sulfur, phosphorus, tin, lead, bismuth and arsenic. that it additionally contains copper and boron in the following ratio of components, wt%: C - 0.05-0.07; Cr - 18.0-20.0; Ni - 5.0-7.0; Mn 9.0-11.0; Mo - 1.8-2.2; Si - 0.25-0.35; N 0.30-0.38; Cu 0.6-1.4; B - from more than 0.01 to 0.015; Al - 0.015-0.035; S≤0.0025; P≤0.015; Sn≤0.005; Pb≤0.005; Bi≤0.005; As≤0.005; Fe is the rest. The method of thermal deformation processing of an ingot consists in heating the ingot to a temperature of 1250-1050 ° C, forging it into a billet with a total degree of deformation of at least 50%, cooling the billet in air, heating the billet to a temperature of 1180-1080 ° C, followed by rolling with a total reduction rate of at least 40% and air cooling to obtain rolled products, heating the rolled products to a temperature of 1150-1080 ° C and final rolling in 2-3 passes with a total reduction rate of 30-80% and a rolling end temperature of 1050-1080 ° C followed by accelerated cooling at a rate of 20-100 ° C / s to room temperature.
