Abstract
1. Способ вторичного охлаждения при непрерывной разливке металлов, включающий охлаждение поверхности вытягиваемого из кристаллизатора слитка водовоздушной смесью, получаемой путем распыления потока воды, содержащей поверхностно-активные вещества, потоком сжатого воздуха, и отсос отработанной водовоздушной смеси, отличающийся тем, что охлаждение поверхности вытягиваемого из кристаллизатора слитка осуществляют водовоздушной смесью с пониженным содержанием кислорода, получаемой путем подачи перед распылением потока воды в поток сжатого воздуха оксида углерода, и/или азота, и/или двуоксида углерода, и/или аргона и снижения концентрации кислорода в получаемой газовой смеси с 21% до 5-10%, при этом концентрация поверхностно-активных веществ в потоке воды составляет 0,001-0,01% от объема подаваемой для вторичного охлаждения воды. ! 2. Способ по п.1, отличающийся тем, что водовоздушная смесь содержит, об. ч.: ! воздух0,8оксид углерода0,2 ! 3. Способ по п.1, отличающийся тем, что водовоздушная смесь содержит, об. ч.: ! воздух0,7азот0,3 ! 4. Способ по п.1, отличающийся тем, что водовоздушная смесь содержит, об. ч.: ! воздух0,5двуоксид углерода0,5 ! 5. Способ по п.1, отличающийся тем, что охлаждение поверхности слитка по малому радиусу осуществляют водовоздушной смесью, получаемой путем подачи в поток сжатого воздуха аргона, а охлаждение поверхности слитка по большому радиусу осуществляют водовоздушной смесью, получаемой путем подачи в поток сжатого воздуха азота. ! 6. Способ по п.5, отличающийся тем, что водовоздушная смесь, подаваемая по малому радиусу содержит, об. ч.: ! воздух0,88аргон0,12 ! а водовоздушная смесь, подаваемая по большому радиусу содер1. The method of secondary cooling during continuous casting of metals, comprising cooling the surface of the ingot drawn from the mold with a water-air mixture obtained by spraying a stream of water containing surfactants with a stream of compressed air, and suction of the spent water-air mixture, characterized in that cooling the surface of the bar drawn from the ingot crystallizer is carried out with a water-air mixture with a reduced oxygen content, obtained by supplying a stream of water to the stream of compression before spraying air of carbon monoxide and / or nitrogen and / or carbon dioxide and / or argon and reducing the oxygen concentration in the resulting gas mixture from 21% to 5-10%, while the concentration of surface-active substances in the water stream is 0.001- 0.01% of the volume of water supplied for secondary cooling. ! 2. The method according to claim 1, characterized in that the air-water mixture contains, about. h.:! air 0.8 carbon monoxide 0.2! 3. The method according to claim 1, characterized in that the air-water mixture contains, about. h.:! air0.7 nitrogen0.3! 4. The method according to claim 1, characterized in that the air-water mixture contains, about. h.:! air 0.5 carbon dioxide 0.5! 5. The method according to claim 1, characterized in that the cooling of the surface of the ingot along a small radius is carried out by a water-air mixture obtained by supplying argon to the compressed air stream, and the cooling of the surface of the ingot along a large radius is carried out by a water-air mixture obtained by feeding nitrogen into the stream of compressed air . ! 6. The method according to claim 5, characterized in that the air-water mixture supplied along a small radius contains, about. h.:! air 0.88 argon 0.12! and a water-air mixture supplied over a large radius of content
