Definitions
- the invention relates to a method for the production of flat and long products in a production plant, for example from thin slabs, thick slabs, billets, blooms, carrier pre-profiles or the like with a continuous casting installation, comprising a mold, a strand guide with a pulling and straightening machine, one Cooling section and a separating device for the strand, as well as a downstream compensation furnace.
- the invention also relates to an apparatus for performing the method.
- the precipitation of aluminum nitride is one reason for these problems due to the rapid heating in direct hot charging and in the rolling process.
- Aluminum nitrides can be found in most aluminum-tempered steels. These are formed and precipitated at the austenitic grain boundaries when the steel goes through the transformation phase from austenite to austenite plus ferrite. If the cast strand is then placed in a furnace for reheating before rolling, the precipitates remain at the austenitic grain boundaries even if the steel changes phase back to full austenite.
- the precipitation of aluminum nitride creates further problems with other deposits such as copper, vanadium, etc., with the result of an extremely break-sensitive microstructure. According to a teaching of document EP 0 650 790 A1, the following is proposed to solve the aforementioned problems:
- a surface temperature between 400 and 900 ° C after "natural tempering", i.e. a reheating by residual heat contained in the block is sought.
- the positioning of a quenching box is also provided immediately after the pulling and straightening machine and before the separating device.
- the document DE 44 16 752 A1 describes a method and a production plant for the production of hot wide strip.
- the corresponding production plant consists of a continuous casting plant for thin slabs between 40 and 70 mm, a compensating furnace and a rolling mill, the exit temperature of the thin slab from the continuous casting machine being above 950 ° C. Between the continuous casting machine and the leveling furnace, the surface temperature of the slab is lowered to such an extent that a structural change from austenite to ferrite / pearlite occurs.
- the cooling section used is designed as a water cooling section and consists of several chilled beams that can be switched on and off.
- the previously known method preferably provides that the temperature of the thin slab is lowered to below 600 ° C. to a depth of at least 2 mm below the surface by choosing the cooling intensity.
- the average surface temperature should not fall below the martensite threshold of the respective material quality.
- the cooling time is chosen so that at least 70% austenite is converted into ferrite / pearlite.
- the document EP 0 587 150 A1 describes a method for the heat treatment of continuously cast slabs or steel blocks, whereby surface brittleness can be effectively avoided. In particular, the occurrence of surface cracks can be effectively suppressed in the case of aluminum-calmed steels, even if the steels contain a proportion of 0.0080 to 0.0300 percent by weight of nitrogen and / or 0.03 to 0.25 percent by weight of lead.
- the process comprises the steps:
- the invention has for its object to provide a method for improving the surface of steel strands for all continuous casting formats, which offers independence from the casting speed and avoids "natural tempering" with core heat of the casting strand.
- the invention proposes in a method according to the preamble of claim 1 that the positioning of the cooling section is carried out downstream behind the separating device, preferably in the immediate vicinity of the compensating furnace or preheating furnace.
- the amount of water and the pressure gives the possibility of regulating the strand transport speed.
- Another embodiment of the method provides that for the intensive removal of heat from the cooling section, this is enclosed with a covering and from it steam and residues of undevaporated cooling water are forcibly drawn off.
- the invention advantageously provides that the water quantity and water pressure are controlled or regulated according to the current strand transport speed.
- the positioning of the cooling section downstream behind the separating device the dependence of the cooling section on the speed of the casting process is eliminated.
- a further embodiment of the method according to the invention provides that the distance between the pulling-out and straightening machine and the separating device is used for homogenizing the temperature of different strand areas, for example on edges or surfaces.
- a further embodiment of the method according to the invention provides that the cooling section is arranged in an area of the strand guide with the highest possible temperature of the strand between the separating device and the compensating furnace.
- a system for the production of flat or long products in a production system for example from thin slabs, thick slabs, billets, blooms, carrier pre-profiles or the like with a continuous casting system, comprising a mold, a strand guide with a pulling and straightening machine, a cooling section and a separating device
- the equalizing furnace be arranged as close as possible behind the cooling section and that these be arranged as close as possible behind the separating device.
- a mold 11 can be seen, which is designed for the continuous casting of a cast strand 6. Below this are segments 12 to 14 of a strand guide 1 with a large number of guide rollers.
- the pulling and straightening machine 2 ensures that the strand 6 is pulled out and transported evenly. Behind it is the separating device in the transport direction. device 3 provided. It can be a pair of scissors or an oxy-fuel cutting machine. This is arranged at a comparatively close distance behind the pulling and straightening machine 2.
- a suction device 10 with a powerful exhaust port is connected to the housing 9, which sucks off the steam generated during quenching and the unused water spray particles and forcibly withdraws it from the cooling section 4.
- the compensating furnace or preheating furnace 5 is arranged at a close distance behind it, wherein recrystallization of the structure in the direction of pearlite / ferrite is initiated by external heat supply.
- the "natural quenching" which is disadvantageous for the surface quality of the cast strand is avoided in this way.
