Definitions
- the invention relates to a converter system with a tiltable converter vessel, which is surrounded by a housing, on the ceiling of which a main exhaust line for discharging the fresh gases and a secondary exhaust line for discharging the smoke arising during charging or pouring is connected, one side wall of the housing having one Has door closable opening.
- exhaust gases which mainly consist of carbon oxides and entrained FeO particles, emerge from the converter mouth during refreshing. These exhaust gases, also known as main emissions, have to be cleaned and the energy they contain may have to be extracted before they can be released into the atmosphere. Even when charging a converter with scrap and pig iron and tapping the molten steel into the ladle, there is sometimes a lot of smoke, which exhaust gases are referred to as secondary emissions or secondary exhaust gases.
- An even greater burden from smoke and smoke development is given in steelworks with floor-blowing converters, for example when carrying out the OBM process, since the introduction of auxiliary materials into the floor nozzles produces sparks in the form of sparks rain caused.
- the invention aims to avoid the disadvantages and difficulties described and has as its object to create a converter system which ensures a complete sheathing of the exhaust gases or emissions-generating sources or system parts without obstructing the workflow.
- a charging container e.g. a ladle, carrying trolley
- the door for closing the opening can be designed as a sliding door, preferably in two parts.
- the extended space can be higher than the rest of the space surrounding the converter, with the secondary exhaust line connecting at the highest point of the housing.
- a common filter system can be provided for the main exhaust line and the secondary exhaust line, that the charging trolley is equipped with mechanical or hydraulic lifting devices for tilting the charging container, or that on the ceiling of the housing in the area of the extended space a rope hoist for tilting the charging container is provided.
- FIGS. 1 and 2 each representing a side view, with one side wall of the housing being removed.
- the converter is designated by 1. It is surrounded on all sides by a housing 2, which is closed at the top by the ceiling 3. Above the mouth of the converter when this is in the upright blowing position, the main exhaust line, the chimney 4, connects, which leads to a filter system.
- the housing is expanded in the tilting direction of the converter - the converter 1 is shown in a tilted position in FIG. 1, this enlarged space being designated by 5. It is closed at the top with the ceiling part 6, which can be arranged higher than the ceiling part 3.
- the secondary exhaust line 7 connects at the highest point.
- the designation 8 on the housing 2 forms the transition to the raised ceiling part 6 of the expanded space 5.
- An opening is provided in the wall of the housing opposite the rear wall, which opening can be closed by a door 9.
- This door can be designed as a one- or two-part sliding door and is guided on rollers 10 on a support on the ceiling of the housing and on rollers 11 on the floor.
- a carriage 12 can be moved into the extended room 5 through the opened door.
- This car can hold a charging container, for example a pig iron pan 13 or a scrap chute 14.
- 15 and 16 are associated hydraulic tilting devices.
- the device according to FIG. 2 corresponds essentially to that of FIG. 1, only with the difference that instead of the hydraulic tilting devices 15, 16, a cable lifting device 17 is attached to the ceiling 6, with which the charging container is tilted.
- the system is operated in such a way that scrap is first charged in the tilted position of the converter.
- the loaded scrap chute is placed on the charging trolley outside the housing by means of a scrap manipulation crane is set and this is moved to the charging position with the door open. Then the door is closed and the tipping process is initiated.
- the smoke plumes generated during charging collect below the ceiling 6 and are discharged or extracted through the main exhaust line 4 and the secondary exhaust line 7.
- the charging trolley is then extended, loaded with a pig iron pan and charging with the liquid pig iron is carried out in the same way.
- the door remains closed during charging and the converter stand is completely sealed off from the hall. Even when the converter is refreshed in the upright position, the door remains closed, so that no ejection, sparks or the like can get into the hall.
- Once the freshening process is finished the steel is put into the pans .
- the main drain line can be switched off during the pouring phase.
- the smoke that arises collects in the room below the ceiling 6 and is discharged through the secondary
