Description
равна по крайней мере сумме высот газораспределительного сло И арматурного сло газопроницаемой футеровки. К внешней и внутренней области кольцевой перегородки подведены патрубки 6 и 7 дл подвода газа.equal at least to the sum of the heights of the gas distribution layer AND the reinforcing layer of the gas-permeable lining. The nozzles 6 and 7 for supplying gas are supplied to the external and internal areas of the annular partition.
Первоначально продувку производ т через оба патрубка 6 и 7 И через всю газопроницаемую футеровку 3 днища ковша дл снижени окисленности металла перед вводом в него раскислителей. После ввода раскислителей лродувку производ т через наружную область кольцевой перегородки 5, создава восход щие газометаллические потоки по всему лериметру ковша. Это приводит -к устранению затененных зон ло периферии и равномерному распределению химического состава и температуры в объеме расплава. Подава затем газ по обоим патрубкам 6 и 7 через всю газопроницаемую футеровку 3 днища ковша, равномерно продуваетс объем раствора, что приводит к эффективному удалению из него вредных примесей и неметаллических включений.Initially, purging is performed through both nozzles 6 and 7 and through the entire gas-permeable lining of the bottom 3 of the ladle to reduce the oxidation of the metal before introducing deoxidizing agents into it. After the introduction of the deoxidizing agents, the thrusting unit is produced through the outer region of the annular partition 5, creating upward gas-metal flows throughout the entire gauge of the ladle. This leads to the elimination of the shaded areas of the periphery and the uniform distribution of the chemical composition and temperature in the volume of the melt. Then, gas is applied through both pipes 6 and 7 through the entire gas-permeable lining of the bottom 3 of the ladle, the solution volume is blown evenly, which leads to effective removal of harmful impurities and non-metallic inclusions from it.
