Definitions

  • the invention relates to a method and a plant for the production of hot-rolled steel strip from continuously cast primary material in successive working steps, the primary material being brought to the hot rolling temperature after solidification and introduced into a rolling mill for rolling to finished strip.
  • a method known from German Offenlegungsschrift 32 41 745 provides that the band-shaped casting strand is wound up into a bundle immediately after leaving the casting machine and passing through the cross-section device and, after heating to the rolling temperature, is rewound to a rolling mill for rolling out to final cross sections.
  • the main disadvantage of this known system is that wound coils are difficult to heat up or require a very long time with great energy and operating costs
  • Warming furnaces are primarily considered to be bogie-type continuous furnaces, lifting hearths or bogie-type furnaces, but they have various disadvantages.
  • loading and unloading of coils at different times is not possible, since when a bogie hearth is removed without another bogie wagon moving up, a gap is created that is not protected against heat radiation. The loading and unloading must therefore always take place simultaneously.
  • the empty bogie wagons must also be returned from the removal side to the loading side. It is necessary to reheat the trolleys, in any case the ceramic benches, to avoid black spots (so-called SKID MARKS).
  • the bundles at the bundle winding station cannot be picked up by the furnace. An additional storage oven must be available to store the bundles.
  • both doors are open at the same time, which leads to higher heat losses.
  • a lifting hearth furnace requires several separately driven lifting hearth beam systems in order to enable the loading and unloading of bundles independently of one another. In the event of a malfunction in the rolling mill, no coils can be picked up from the furnace for storage. Here too, if bundles are to be saved, there is a second one Furnace system required.
  • a hearth hearth can accommodate one or more bundles according to the design. If the storage capacity must be equal to the contents of the pan, several wagon hearth furnaces are required. The disadvantage of several furnaces is that the routes to the bundle unwinder are different and, as a result, the bundles do not have the same temperature.
  • the object of the present invention is therefore to present a process for the production of hot-rolled steel strip and a continuous casting installation with a downstream hot strip rolling mill, with which the disadvantages mentioned can be avoided or the difficulties eliminated and with which also in adaptation to different production quantities of the individual strands in multi-strand systems and in Operational disruptions economically, ie can be used at high capacity and in particular relatively low investment costs are required.
  • the object is achieved for the process according to the invention in that after the hot rolling temperature has been reached, the primary material is wound into bundles, temporarily stored in a rotary hearth furnace and, if necessary, called up, unwound and rolled out into finished strip.
  • the intermediate storage takes place immediately before entering the finishing train.
  • the temperature distribution is evened out with only short dwell times, which has an advantageous effect on the rolling process.
  • the bundles are temporarily stored in a horizontal position or with a horizontal winding axis, as a result of which particularly simple charging is provided using known and proven manipulators.
  • Heat is expediently supplied during the intermediate storage. In this way, heat losses on the surface can be compensated for by reheating and ideal rolling conditions can be set.
  • the horizontal position of the bundles is particularly effective here.
  • the task is solved in that a coil winder and a rotary hearth furnace and a coil unwinder are arranged between the first furnace and the finishing train. It is particularly expedient for a plurality of bundles formed from parallel primary material strands to be temporarily stored in only one rotary hearth furnace. This can considerable investment costs can be saved.
  • the rotary hearth furnace is integrated into the production line and each has a loading and unloading point. This measure saves space and at the same time creates an emergency store in the event of operational disruptions.
  • the rotary hearth furnace is arranged next to the production line and provided with only one loading and unloading point, which greatly reduces heat losses.
  • the charging device is optionally arranged in the inner circle of the furnace, with the advantage of a further reduced space requirement.
  • the rotary hearth furnace has an outer diameter of approximately 13.5 m and is designed to accommodate 10 bundles.
  • Other design data depend on the ladle content of the strip caster.
  • the belt caster is generally designed as a double-strand system / two-strand belt caster and equipped with two coil winders downstream of the furnaces.
  • the first furnace is designed as a shortened roller hearth furnace without a compensation zone with an upstream induction heating.
  • the overall length the system can be greatly shortened, since the roller hearth furnace is only about 80 m long with a heating zone and a short buffer zone.
  • the induction heater takes up little space and is a great advantage of bringing the missing amounts of heat into the belt in the shortest possible time.
  • Figure 1 denotes a strip caster with two strands (1 ', 1''), each of which is followed by a cross-cutting device (2), for example a flame cutting machine or scissors for separating the cast and the caster (1) with one Speed of about 6-7, maximum 8 m / min leaving belts (1 ′, 1 ′ ′) in sections of the same length, for example 65 m.
  • the individual partial lengths of the strips are then temporarily stored in two roller hearth furnaces (6) of approximately 150 m in length and brought to a homogeneous hot rolling temperature of approximately 1050 to 1100 degrees Celsius.
  • the roller hearth furnaces (6) have, for example, a 3 m long, unheated, hinged hood on the entrance side, followed by a 70 m long heating zone, a 65 m long compensation zone and a buffer zone of 12 m.
  • the partial lengths leaving the furnaces (6) are wound into bundles or coils (11) in a bundle winder or two coilers (10).
  • the coil winding speed is about 2 - 3 m / s.
  • the bundles (11) then have, depending on the bandwidth, between 1100 and 1350 mm with a thickness of 40 mm and one Belt length of 65 m, a coil weight between 22 and 27 t.
  • the bundles (11) are fed from the bundle transfer stations (12) via a transport system (14) to a charging or charging device (18) which, according to the invention, brings the bundles (11) into a rotary hearth furnace (20)
  • the rotary hearth furnace (20) is advantageously arranged in the line between a two-strand belt casting machine (or several single-strand belt casting systems) and the hot broadband rolling mill (40). It is essentially designed as a storage furnace or compensating furnace and has, for example, about 10 to 25 ring-shaped memory locations (21).
  • the annular furnace (20) has fire-proof insulation on all sides, charging openings (24, 25) which can be closed preferably being provided in the outer and / or inner wall (22, 23), in the present case a loading opening (24) and a removal opening (25 ).
  • the storage spaces (21) inside the furnace (20) can be moved in a circular path between the fixed outer and inner walls (22, 23) at any speed and direction.
  • a bundle (11) is removed in each case from the removal or decharging device (28) and fed to a bundle unwinder or decoiler (30) by means of a suitable bundle transfer device (29).
  • the transfer can take place in any manner, for example also by means of a removal device (28) which is pivotable between the removal position and the decoiler (30).
  • the unwound tape is then in a known manner conveyed via scissors (32) and a descaling system (34) to the finishing mill (40), the unwound strip being rolled from the final rolling thickness to the finished strip (41) in the finishing mill (40).
  • the finished belt (41) After leaving the last rolling stand of the finishing train (40) with an outlet temperature of approximately 860 degrees Celsius, the finished belt (41) passes through a cooling section in a known manner in order to be subsequently wound up by an underfloor reel at a temperature of approximately 560 degrees Celsius (not shown) .
  • the loading and unloading of bundles (11) can take place independently of one another.
  • the coils (11) pass through only a partial area of the furnace (20), corresponding to the required dwell time between the loading and unloading station (18, 28). If faults occur in the rolling mill (40), additional bundles (11) can be buffered.
  • the rolling mill (40) After the rolling mill (40) has been put back into operation, it can be removed from the furnace (20) in any order.
  • the bundles (11) are transported through the oven (20) on a stove prepared for this purpose. This has the furnace chamber temperature and prevents black spots, i.e. the so-called SKID MARKS. A temperature equalization takes place in the bund during the dwell time.
  • the furnace (20) can advantageously be designed for low-scale heating.
  • the furnace combination according to FIG. 2 has the advantage that the total length of the furnaces (6, 20) in the production line is shorter than a roller hearth furnace (6) 1, since the compensation zone can be omitted.
  • the length of the roller hearth furnaces (6) here is about 80 m with a belt length of 65 m, consisting of a heating zone of 68 m and a buffer zone of 12 m, which is required for the subsequent process steps.
  • the belts (1, 1 ') run through the furnaces (6) during the reheating at the casting speed.
  • the induction heater (4) has the task of introducing the missing amount of heat into the belt.
  • the heating power of the induction heaters (4) is increased according to the missing amount of heat, the switch-on time being calculated.
  • the data for this are the measured strip temperature, the casting speed and the furnace chamber temperature.
  • the individual inductors (4) are switched off when the end of the strip has passed them.
  • a temperature compensation in the collar (11) to the required Temperature profile can take place in the downstream rotary hearth furnace (20).
  • the arrangement and mode of operation of the rotary hearth furnace (20) and the upstream and downstream units correspond to the description of FIG. 1.
  • the roller hearth furnaces (6) can also be extended, whereby in in the individual control zones, the furnace is alternately operated at heating or compensation temperature.
  • the rotary hearth furnace (20) can also be arranged next to the production line of the belt casting system (1) and serves here as a purely bund storage furnace.
  • the bundles (11) are loaded or removed at the same point via the charging opening (24). This makes it possible to keep the paths of the transport system (14) short.
  • closable openings, each with a door (24, 26) are provided in the outer and inner walls (22, 23) of the rotary hearth furnace (20) for the charging device (18) arranged in the inner circle of the furnace.
  • the furnace (20) there are also two slides (27) which close the rest of the furnace space during charging.
  • the bundles (11) are transported to and from the rotary hearth furnace (20) by means of a bundle transport system (14).
  • the bundles (11) can be called up from the furnace (20) in any order.
  • the rotary hearth furnace (20) can be designed for a charging device (18) arranged on the outside.
  • the transport system (14) according to FIG. 4 is particularly useful for systems in which a greater distance has to be bridged between the strip casting machines (1) and the rolling mill (40).
  • the main area of application is therefore the retrofitting of conventional rolling mills to strip casting systems with a subsequent continuous mill.
  • Behind the coilers (10) and the coil transfer devices (12) are lifting stations (13) for lifting the bundles (11) to the level of the transport system (14), i.e. provided at the level of the trolley (15).
  • the carriages (15) are equipped with removable thermal insulation hoods, which prevent high heat losses during the movement of the bundles (11) to the rotary hearth furnace (20).
  • Carriage (15) has its own drive and can be moved independently.
  • the rail guide (16) depends on the local conditions and project specifications.
  • the thermal insulation hoods of the wagons (15) are equipped with burners, pilot burners etc. and a temperature measurement and can be heated or reheated at the places provided.
  • the rotary hearth furnace (20), the charging openings (24, 25) of which lie opposite one another, is arranged in the transport direction following the rail path (16). The method of operation of the device and the following units essentially corresponds to the description of FIG. 1.
  • the rotary hearth furnace (20) can also be arranged next to the production line of the strip casting system (1), similar to the system shown in FIG. 3 and in turn serves as a purely bund storage oven.
  • the bundles (11) are loaded or removed at the same point via the charging opening (24). This in turn gives the possibility of keeping the paths of the transport system (14) short.
  • the bundles (11) can be called up from the oven (20) in any order.
  • one or more rotary hearth furnaces can be provided in any arrangement, for example also in multi-strand systems. It may also be useful to arrange the rotary hearth furnace directly behind the casting machine or the scissors and to completely replace the tunnel furnaces previously used. The respective constructive design is left to the specialist to adapt to the special use of the system.
