Description
(54) КОНВЕРТЕР(54) CONVERTER
Изобретение относитс к области черной металлургии , в частности к конвертерам с верхней и донной прод вкой.The invention relates to the field of ferrous metallurgy, in particular to converters with top and bottom products.
Известен конвертер с донной продувкой, состо щий из футерованного корпуса с опорным кольцом и полыми цaпфa ш, через которые проходит газовый трубопровод, соединенный с донными фурмами.A converter with bottom blowing is known, consisting of a lined body with a support ring and hollow capps through which a gas pipeline passes, connected to bottom tuyeres.
Недостатком известной конструкции вл етс зшчигельные термические напр жени , возникающие в корпусе конвертера и громоздкость его конструкции.A disadvantage of the known construction is the excessive thermal stresses arising in the converter housing and the bulkiness of its construction.
Отличительной особенностью предлагаемого конвертера вл етс то, что цапфа снабжена конценгрично расположенными в ней трубами, образующими между собой и стенкой цапфы тракты дл подвода и отвода охладител к опорному кольцу и подвода газа к фурмам, при этом тракты подвода и отвода охладител соединены с полостью опорного кольца трубопроводами, расположенными в соосно выполненных в цапфе и опорном кольце отверсти х , и тазовый тракт соединен трубопроводом с фурмами, причем подвод щие и отвод щие газ трубопроводы соединены с цалфами с возможностью поворота относитепько их.A distinctive feature of the proposed converter is that the trunnion is equipped with concentrically arranged pipes in it, forming paths between themselves and the trunnion paths for supplying and discharging the cooler to the support ring and supplying gas to the tuyeres, while the cooling and discharging paths of the cooler are connected to the cavity of the support ring pipelines arranged in coaxially made holes in the trunnion and the support ring, and the pelvic tract is connected to the tuyeres by a pipeline, and the gas inlet and outlet pipelines are connected to the columns with POSSIBILITY turn otnositepko them.
На фиг. 1 показан предлагаемьгй конвертер в положении горловиной вш1з; на фет, 2 - опорное кольцо с левой цалфой, продольное сечеш1е.FIG. 1 shows the proposed converter in the position of the neck; on fet, 2 - support ring with left tsifra, longitudinal section.
Корпус 1 конвертера крепитс в опорном кольце 2 при помощи крогшпейпов 3--6.The housing 1 of the converter is fixed in the support ring 2 with the help of 3--6 kroshpeypov.
Внутрь опорного кольца 2 со стороны цапф 7 и 8 встроены опорные блоки 9,10, в которых закреплены цапфы 7 и 8. Цапфы опираютс на несущую конструкцию 11.Inside the bearing ring 2, on the side of the pivots 7 and 8, the supporting blocks 9, 10 are embedded, in which the pins 7 and 8 are fastened. The pins are supported on the supporting structure 11.
В теле цапфы 7 по осевой оси выполнен канал 12, в котором размеще1«( трубы 13 и 14, образующие между собой и стенкой цапфы тракты дл подвода и отвода охладател к опорному кольцу 2, в теле которого выполнена полость 15 и радиальные каналы 16,17, соедин ющие полость 15с каналами 12 и 18. Радиальные каналы 16 и 17 совпадают с соосно вьшолненпыми в цапфе каналами 19 и 20. Каналы 21 и 22 выполнены соосно в цапфе 7 и опорном кольце 2 дл подачи газа к фурмам.In the body of the trunnion 7 along the axial axis there is a channel 12 in which is placed 1 "(pipes 13 and 14, which form paths for supplying and discharging the coolant to the support ring 2 between themselves and the wall of the trunnion, in the body of which there is a cavity 15 and radial channels 16,17 connecting cavity 15 with channels 12 and 18. Radial channels 16 and 17 coincide with coaxially aligned channels 19 and 20 in a pin. Channels 21 and 22 are coaxial with pin 7 and support ring 2 for supplying gas to the tuyeres.
Дашюе изобретение позвол ет компенсировать термические напр же1ш , возникающие в корпусе конвертера за счет охлаждени опорного кольца, и значтельно 5Т1ростить конструкцию конвертера.This invention makes it possible to compensate for the thermal stresses that occur in the converter housing by cooling the support ring, and significantly increase the converter design 5T1.
