Description

Изобретение относится к черной металлургии, в частности к доменному производству.The invention relates to ferrous metallurgy, in particular to blast furnace production.

Известен качающийся желоб с углубленной ванной, который содержит футерованную ванну, сливные носки и привод ⁵ качания.Known rocking trough with a recessed bath, which contains a lined bath, drain socks and swing drive ⁵ .

Однако обслуживание желоба очень сложное и требует дообрудования линейно* го двора дополнительными кранами в зоне постановочных путей.However, the maintenance of the gutter is very complicated and requires additional equipment of the linear yard with additional cranes in the area of production tracks.

Это объясняется тем, что все желоба подобного типа расположены над проемами линейного двора, недоступ- м ными для обслуживания краном. Поэтому над этими проемами, гда это возможно, устанавливают дополнительные мостовые краны, кранбалки или другое грузоподъ2 емное оборудование. На многих печах <The closest to the proposed technical essence · a trough for casting products of the blast furnace, comprising lined housing ₁₅ sliv- nye socks and trolley fl J • A disadvantage is the difficulty of its service. This is explained by the fact that all gutters of this type are located above the openings of the linear yard, inaccessible for crane service. Therefore, wherever possible, additional bridge cranes, crane cranes or other lifting equipment are installed above these openings. On many stoves <

установить дополнительные краны невоэч можно, да и сама такая реконструкция весьма дорогостоящая операция и экономически не целесообразна, так как требует перестройки всего здания линейного двора, с увеличением его высоты. А без такой реконструкции обслуживание и ремонт желоба производятся практически вручную со всеми вытекающими отсюда последствиями, включая задержки выпусков чугуна из печи, перевод печи на 'тихий ход', что, в конечном итоге, снижает производство чугуна.It is possible to install additional non-power cranes, and such reconstruction itself is a very expensive operation and is not economically feasible, since it requires the reconstruction of the entire linear courtyard building, with an increase in its height. And without such a reconstruction, the maintenance and repair of the gutter is carried out almost manually with all the ensuing consequences, including the delay in the release of pig iron from the furnace, the transfer of the furnace to a “quiet run”, which ultimately reduces the production of pig iron.

Цель изобретения - механизация обслуживания желоба его ремонта.The purpose of the invention is the mechanization of servicing the gutter for its repair.

Поставленная цель достигается тем, что в желобе для разливки продуктов доменной плавки, содержащем футерованный корпус с цапфами, сливные носки и тележку, тележка выполнена в виде двух балок с катками и подшипниковыми опорами под цапфы, размешенными по обе стороды футерованного корпуса.This goal is achieved by the fact that in the trench for casting blast furnace products containing a lined body with trunnions, drain socks and a trolley, the trolley is made in the form of two beams with rollers and bearing supports under the trunnions, placed on both sides of the lined case.

The invention relates to ferrous metallurgy, in particular to the domain production. There is a well-known trough with a deep bath, which contains a foot & bath, drain socks and a drive: swing. However, the maintenance of the gutter is very difficult and requires the addition of linear cranes in the zone of production tracks to the linear installation from the courtyard. The closest to the proposed by the technical essence is the chute for casting the blast-smelting products containing lined corp., Slv & socks and trolley fl. J The disadvantage is the complexity of its maintenance. This is due to the fact that all of these types of troughs are located above the openings of the linear yard, which are inaccessible for servicing by a crane. Poetsvdu above these openings, where it is possible, install additional bridge cranes, kranbalki or other lifting equipment. On many furnaces, it is possible to install dowel-free cranes, and even this reconstruction is a very expensive operation and economically is not advisable, since it requires rebuilding the entire building yard, with an increase in its height. And without such a reconstruction, the maintenance of the bath and the repair of the gutter are carried out practically by hand with all the ensuing consequences, including delays in starting the iron from the furnace, transferring the furnace and a quiet course, which ultimately reduces the production of iron. The chain of the invention of the mechanization of the maintenance chute of its repair. This goal is achieved by the fact that in the chute for spreading the products of this kind of melting, comprising a housing with trunnions, drain socks and a trolley, the trolley is made in the form of two beams with rollers and bearing parts under the trunnions located along both lined hulls. FIG. 1 shows a general view of the gutter, its location in the linear yard and the conditional position during operation; in fig. 2 invention and plan. The chute for lining the blast smelting products consists of a lined bath 1, drain socks 2 and a drive 3 for swinging the chute. The drive has a crank mechanism connected by a connecting thrust 4 with an eye 5, attached to the body of the bath. The bath is located on (the carriage 6 on which the bearings 7 are mounted with the pillars 8 of the trough placed in them. The cart with the help of the rope 9 and the 1O units is connected with the drive 11. The cart is mounted on the directions 12 and is on the opposite side equipped with the rope 13 thrown through block 14. The device works as follows: metal entering; into bath 1, it is drained into a ladder located on both sides of its socks

2. To do this, with the aid of a drive 3, rolling and detachable pulley 4, the latter is tilted towards one of the buckets. By turning the groove around the axis of the trunnion 8, the direction of discharge is changed. metal. If it is necessary to repair the chute or to replace it, the rope 9 is pulled through the block 14 using the hook of the casting yard. The detachable pull 4 is disconnected beforehand. V. By moving Yanat, the trolley 6 with the chute mounted on it will be mixed along the guides 12 to the zone served by the crane of the casting yard. After that, the chute is removed and installed at the site of its repair (conventionally in Fig. 1). After the repair, the gutter is again installed and poured onto the trolley, and with the help of the drive for the movement 11, the rope 9 and the blocks 10 are fed into the work area. The present invention allows to mechanize the process of servicing the chute. No need to install & pour over the openings of the blast furnace sp &. Special overhead cranes or other additional lifting equipment for repairing or replacing the gutter. Especially valuable is the proposal for existing blast furnaces, since their design and the creation of a single-core casting system on them is practically impossible without such a solution. This proposal is incorporated in the project of reconstruction of the blast furnace № 9 of the metallurgical plant named after Dzerzhinsky. The estimated economic effect is about 191 thousand rubles. in year.
