Изобретение относитс к черной металлургии.This invention relates to the steel industry.

Известен конвертер, съемное днище которого крепитс к корпусу при помощи т ги и клиньев 1 .A converter is known, the removable bottom of which is fastened to the body with the help of ti and wedges 1.

Однако така конструкци требует значительных затрат ручного труда по замене днища.However, such a structure requires considerable manual labor for the replacement of the bottom.

Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс конвертер, содержащий корпус, отъемное днище и элементы креплени днища к корпусу , каждый из которых выполнен в виде башмака, подвешенного к корпусу с возможностью поворота относительно смещенной от его центра т ткести горизонтальной оси, и подпирающего его к днищу клина 2 .The closest to the invention in technical essence and the achieved result is a converter comprising a housing, a removable bottom and bottom fastening elements to the housing, each of which is made in the form of a shoe suspended from the center with a rotatable relative to its horizontal axis displaced from its center. and propping it to the bottom of the wedge 2.

Однако и така конструкци требует значительных затрат ручного труда при замене днища.However, such a structure requires significant manual labor when replacing the bottom.

Цель изобретени - сокращение затрат ручного труда при замене днища.The purpose of the invention is to reduce the cost of manual labor when replacing the bottom.

Это достигаетс тем, что каждый .Зашмак выполнен с выступами на его 50КОВОЙ поверхности, а днище снабжено захватами, взаимодействующими с выступами.This is achieved by the fact that each. Zashmak is made with protrusions on its 50KOVOY surface, and the bottom is provided with grippers interacting with the protrusions.

На фиг. 1 изображен предлагаемый конвертер со съемным днищем; на фиг. 2 дана схема установки днища; на фиг. 3 - вид по стрелке А на фиг. 2.FIG. 1 shows the proposed converter with a removable bottom; in fig. 2 given the installation of the bottom; in fig. 3 is a view along arrow A in FIG. 2

На нижней части корпуса 1 конвертера имеетс опорное кольцо 2 дл поддержани огнеупорной футеровки 3. На кольце 2 разъемно кре0 питс днище 4 с футеровкой 5. Вокруг днища 4 на кольце 2 корпуса 1 жестко в радиальном направлении установлены кронштейны 6, снабженные опорными элементами, которые выпол5 нены в виде башмаков 7, опирающихс на клинь 8. Башмаки 7 подвешены к корпусу с возможностью поворота относительно горизонтальных осей 9, смещенных относительно их центра On the lower part of the converter housing 1 there is a support ring 2 for supporting the refractory lining 3. On the ring 2 there is a separable bottom 4 with a lining 5. Brackets 6 are rigidly installed in the radial direction around the bottom 4 on the ring 2 of the housing 1 and equipped with support elements that are made 5 not in the form of shoes 7, resting on a wedge 8. Shoes 7 suspended from the body with the possibility of rotation relative to horizontal axes 9 displaced relative to their center

0 т жести. На боковой поверхности каждого башмака 7 выполнены выступы 10, взаимодействующие с захватами 11 днища 4.0 tons of tin. On the side surface of each Shoe 7, the projections 10, interacting with the grippers 11 of the bottom 4.

Устройство работает след тощим The device works track skinny

5 образом.5 way.

Claims

The bottom 4 is transported and installed with a jack under the converter housing. Before lifting the bottom 4, the shoes 7 hang obliquely on, the axles 9 and the protrusions 10 rest on the side surface of the cheeks of the brackets b. When the bottom 4 is lifted, the grippers 11 catch the protrusions 10. The shoes 7 rotate around the axes 9. When the bottom 4 rests against the support ring 2, the shoes 7 will be located with in the working position. The bottom 4 is locked and the wedge 8 is seized. After that, the converter is ready for operation. For removal, the bottom 4 is supported by a jacking cart, a wedge 8 is selected, lowered and transported to the lining repair department. After lowering the bottom 4, the shoes 7 rotate on the axles 9, resting with the projections 10 on the grippers 11. After disengaging from the brackets with the grippers 11 of the bottom 4, the shoes 7 with the projections 10 resting on the cheeks b, is in the position O closed. Then the cycle of the installation-removal of the bottom is repeated. The proposed device is simple, requires minimal manual labor, provides the maximum installation and removal speed of the bottom, which ultimately increases the overall performance of the converter. Claims of the Invention Converter, comprising a housing, a detachable bottom and bottom mounting elements to the housing, each of which is designed as a shoe suspended from the housing so that it can be rotated relative to the horizontal axis offset from its center of gravity, and supporting it to the wedge bottom, characterized by that, in order to reduce the cost of manual labor when replacing the bottom, each bass-mak is made with protrusions on its lateral surface, and the bottom is equipped with grips that interact with the protrusions.
