Definitions
- the longitudinal-transverse-longitudinal transport system has to overcome the travel path to one or the other of the two outer casting machines or casting lines in two out of three cases before taking over the next thin slab winding.
- this will result in coordination difficulties for the entire system, which will affect its capacity utilization.
- the ferries as a longitudinal transport containing, traversable ovens, for. B. roller hearth furnaces are designed and if each includes a fixed roller hearth furnace an oven area, a compensation area and a buffer area.
- the transport speeds of all of the transport systems provided between the casting machines or casting lines and the continuous hot-rolled strip finishing train can be controlled within the range determined on the one hand by the casting speed in the individual casting machines or casting lines and on the other hand by the pull-in speed of the hot-rolled strip finishing train so that there is a range between the successive introduction of two thin slabs into the hot-rolled strip finishing train to have buffer times sufficient, for example, to carry out roll changing operations.
- the buffer storage of thin slabs can be effected over the entire distance between the casting machines or casting lines and the hot-rolled strip finishing train, because these distance areas as a whole, i.e. also in the area of the longitudinal-transverse-longitudinal transport system or ferries of furnaces that maintain the rolling temperature or heating devices is bridged.
- a furnace 4, a compensation area 7 and a buffer area 10 are arranged downstream of the casting machine or casting line 1 in the aligned position.
- an oven 5 In the aligned position with the casting machine or casting line 2 there is an oven 5, a compensation area 8 and a buffer area 11, while in the aligned position with the casting machine or casting line 3 an oven 6, a compensation area 9 and a buffer area 12 are provided.
- Each oven 4 or 5 or 6 is designed with the compensation area 7 or 8 or 9 and buffer area 10 or 11 or 12 downstream thereof as a continuous roller hearth oven 13 or 14 or 15, which is practically a continuous one Longitudinal transport forms.
- a continuous roller hearth oven 13 or 14 or 15 which is practically a continuous one Longitudinal transport forms.
- a receiving furnace 18 is created in the flight position with the middle casting machine or casting line 2 and the middle roller hearth furnace or longitudinal transport 14, to which the hot strip mill 19, again in the flight position, connects.
- Each of the casting machines or casting lines 1, 2 and 3 is designed for the continuous production of a cast strand 21 or 22 or 23, which is only indicated for the sake of simplicity.
- the cast strand 21 is continuously divided into thin slabs 24 immediately behind the casting machine or casting line 1, which gradually pass through the roller hearth furnace 13 with the furnace region 4, the compensation region 7 and the buffer region 10.
- Corresponding thin slabs 25 are also separated from the cast strand 22 behind the casting machine or casting line 2 and guided into the roller hearth furnace 14, where they can pass through the furnace region 5, the compensation region 8 and the buffer region 11 one after the other.
- the casting strand 23 is continuously divided into thin slabs 26 which enter the roller hearth furnace 15 and run there one after the other through the furnace region 6, the compensation region 9 and the buffer region 12.
- the casting machine or casting line 2 first started to apply the casting strand 22, and then the casting machine or casting line 3 started its casting strand 23 delivers and finally the casting machine or casting line 1 has started to deliver its cast strand 21.
- the first thin slab 25 is separated from the cast strand 22 and transported in the roller hearth furnace 14 through the furnace region 5, the compensation region 8 and the buffer region 11.
- the ferry 16 Since the casting machine or casting line 1 has last started to deploy its cast strand 21, the ferry 16 is thus moved in the transverse direction from its basic position according to FIG. 1 until it comes into alignment with the roller hearth furnace 14 and the receiving furnace 18, as in FIG Fig. 2 of the drawing can be seen.
- the first thin slab 25 is then transported directly in the longitudinal direction via the ferry 16 into the receiving furnace 18 and can then be drawn into the hot strip mill 19 from this.
- a thin slab 26 is moved from the buffer area 12 of the roller hearth furnace 15 onto the ferry 17 which remains in its basic position, as can be seen from FIG. 2 of the drawing.
- the two ferries 16 and 17 are brought together or synchronously from their operating position corresponding to FIG. 2 into the operating position according to FIG. 3.
- the ferry 16 comes out of its flight position with the roller hearth furnace 14 in the flight position with the roller hearth furnace 13, while the ferry 17 lies out of the flight position with the roller hearth furnace 15 in the flight position with the downstream receiving furnace 18.
- the thin slab 26 resting thereon is transported by the ferry 17 into the receiving furnace 18, the thin slab 24 simultaneously reaches the ferry 16 from the buffer area 10 of the roller hearth furnace 13.
- both ferries 16 and 17 are again moved synchronously or together into the position corresponding to FIG. 3.
- the loading time for the thin slabs 24, 25, 26 from the buffer zones 10, 11, 12 of the roller hearth furnaces 13, 14, 15 corresponds to the unloading time which is required for the transfer of the individual thin slabs 24, 25, 26 of the ferries 16 and 17 in the receiving furnace 18 is required.
- the two ferries 16 and 17, which can each be operated as longitudinal / transverse / longitudinal transport systems, are also heatable. They can preferably be designed as roller hearth furnaces which can be moved in the transverse direction, so that their hearth rollers can be used for the forced longitudinal transport of the individual thin slabs 24, 25, 26.
- the two ferries 16 and 17 can either maintain their position or move to a complementary strand combination.
- the decisive factor here is always the circumstance from which the cast strands 21, 22, 23 produced can at the earliest be expected to receive a thin slab 24, 25, 26 ready for takeover. All cast strands 21, 22, 23 can be treated equally by the combination of the two ferries 16 and 17.
- the subsequent times of the thin slabs 24, 25, 26 can - depending on the respective feed speed of the hot broadband finishing train 19 - either be made more uniform or, in order to achieve buffer times for the execution of roll change operations, can be carried out in a targeted and symmetrical manner.
- all longitudinal transports that are operated between the casting machines or casting lines 1, 2, 3 and the hot broadband finishing train 19 must be controllable in terms of their transport speed, on the one hand by the casting speed of the individual cast strands 21, 22, 23 and on the other hand are determined by the feed speed of the hot strip mill 19.
