Definitions
- the invention relates to a method and a plant for the production of hot strip (pre-material) from silicon-alloyed steels for further processing into grain-oriented sheets, such as electric sheets.
- the further processing is not the subject of the present invention; it takes place in cold rolling mills.
- the time required for the rolling process energy is thus almost completely covered by the amount of heat contained in the cast strand.
- the temperatures are controlled by changing the roller speed, by cooling and from the roller contact, so that sets a final rolling temperature of 880 0 C. It follows a slow cooling in the cooling section and a subsequent coiling.
- Multi-stage temperature adjustment systems for heating a cast product before it enters a rolling train are known from EP 1 469 954.
- EP 0 415 987 B2 discloses a process for the continuous production of strip steel or sheet steel from thin slabs of about 50 mm thickness, the thin slabs being produced on continuous sheet casting plants with a horizontal outlet direction.
- the method comprises the procedural steps: rolling the thin slab after solidification of the strand in an arcuate guide shaft at temperatures of more than 1100 0 C, cooling the slabs during radiation or descaling, inductive reheating to a temperature of about 1100 0 C and rollers the thin slab in at least one rolling mill.
- a temperature is set in the slab, so that sets a temperature gradient at the deformation means of the rolling train in such a way that when tapping into the last roll stand, the temperature is within sufficient for a good deformation order of magnitude.
- the rolling stock temperature dropped, for example, to 988 ° C and sufficient as a tapping temperature for the last forming step.
- the rolling stock leaves the last mill stand with a temperature of 953 ° C or less and is then separated at a further lowered temperature in the desired lengths, stacked or reeled. If necessary, one or more stages of inductive intermediate heating may be provided between the individual stands.
- the object of the invention is to make the heat treatment in a known process and a known plant, with which hot strip pre-material of Si-alloyed steels is produced for further processing into grain-oriented metal sheets, effective.
- an inlet temperature is set in the finishing train, which ensures a favorable Ausscheidungsmorphologie in the rolling stock.
- Known in the prior art single-stage temperature-adjusting systems are not able to heat the cast product to the required for setting the desired / required recrystallization state high temperatures of preferably more than 1250 0 C inlet temperature in the rolling mill.
- the high temperatures are advantageously achieved in the claimed method in that a two-stage preheating of the cast product, comprising a Primärergiebeauchte and an inductively heated stage is performed.
- the claimed two-stage heat treatment also has the advantage that it can heat the cast product not only - if necessary - to temperatures above 1250 0 C, but also to lower inlet temperatures, if necessary for setting other desired structural or recrystallization states should be; In this respect, the claimed method is very universally applicable.
- the control of the temperature in the subsequent finishing train depends on the final structure to be achieved and is set via a combination of rolling speed and use of inter-frame cooling.
- the final rolling temperature (TWE) and the final rolling speed of the rolling stock are set to values at which complete recrystallization of the steel no longer occurs and the rolling stock becomes after the last Stitch in the hot rolling line of the final rolling temperature (TWE) to a temperature (T A ) quenched, which ensures the setting or freezing a desired RekristallistionsShes over the strip thickness.
- the final rolling temperature (T W E) of the rolling stock to temperatures of at least 950 0 C, preferably above 1000 0 C, is set, and that then, preferably in the immediate, the Walzgut to temperatures (T A ) of at most 650 0 C, vorugitate below 600 0 C, more preferably below 450 0 C within 10 s, is quenched. In this case, a complete recrystallization of the hot strip is suppressed.
- the proportion of the recrystallized structure can be adjusted via the strip thickness.
- the temperature of the cast product is set to values between 1000 and 1100 0 C and that in the subsequent intensive heating stage, the temperature is increased to values of 1250 ° C.
- the preheating stage is carried out in a gas- or oil-fired oven and the subsequent intensive stage in an induction heating stage. This has the particular advantage that the preheating can take place in a roller hearth furnace, while the heating step is shifted to temperatures above 1200 0 C in an inductive heating zone. This prevents that the roller hearth furnace is charged too much, which could possibly lead to its thermal destruction.
- the slab surface is descaled.
- descaling is carried out in a descaling device between the preheating stage and the intensive heating stage.
- the setting of the inlet temperature in the finish rolling stage is then carried out by means of induction heating.
- the finish rolling stage can consist of a single or multi-layered consist of a preliminary relay and a multigrade end squadron. The distance between these two can be bridged by a roller table or bezeizten heat tunnel.
- removal of the scale is to be carried out in addition to or in addition to the abovementioned descaling measures even before the roller hearth furnace in order to protect the rollers of the furnace against scale buildup and thus the underside of the slab from undesired markings and to improve the heat transfer into the slab.
- the means for cooling the rolling stock comprises components for quenching the rolling stock to temperatures below 600 0 C, preferably below 450 0 C.
- the hot rolling train is designed as a compact finishing line.
- the hot rolling line is formed divided into at least one pre-and at least one Endwalzstaffel.
- Fig. 1 is a schematic representation of a plant for carrying out the erfindungsgze touch process.
- Fig. 1 shows a plant 1 for the production of rolling stock in the form of sheets or strips of silicon-alloyed steel for further processing into grain-oriented sheets, such as electric sheets, which are heat treated and rolled without intermediate cooling to room temperature, so that then the rolling stock with desired Microstructure properties is available.
- the plant 1 comprises a continuous casting plant 1a.
- the close to final cast strand in the form of a cast product 2 is cut in front of the roller hearth furnace 3 using a pair of scissors 4, which then come from the casting heat directly enter the roller hearth furnace 3 to be heated to temperatures of 1000 to 1100 0 C. or to learn a temperature compensation.
- the slabs are preferably thin slabs with a thickness of up to 120 mm.
- the heated slabs then preferably pass through a descaling device 5 and then enter an intensive heating stage 6.
- the slabs are heated in a short rapid heating process at inlet temperatures of 1100 to 1300 0 C, preferably above 1250 0 C.
- the preheating stage 3 is carried out in a gas or oil-fired furnace such as a roller hearth furnace 3 and the subsequent Intensivheittress 6 in an induction heating.
- the intensive heating stage 6 must be designed to ensure an inlet temperature T ⁇ in the cast product 2 in the rolling mill of more than 1200 0 C.
- the preheating stage 3 and the intensive heating stage 6 form a temperature The adjustment means 7.
- the means for performing the heat treatment include the preheating stage 3, the intensive heating stage 6 and interstand cooling means 10.
- the cast product 2 is descaled again (second descaling stage 8) and introduced into a hot rolling line 9a or 9b.
- the hot rolling train 9a or 9b may be a compact finishing line 9a or divided into a preliminary and a final rolling 9b.
- the number of scaffolds in each of the two partial scales is not fixed.

- the multi-stage heat pretreatment takes place with the temperature setting system 7, which includes the preheating stage 3 for preheating the cast product 2 and the intensive heating stage 6 for adjusting the inlet temperature T e in the cast product 2 in the hot rolling line.
- the final rolling temperature TWE and the final rolling speed of the rolling stock are set to values at which complete recrystallization of the steel no longer takes place.
- the rolling stock is quenched from the final rolling temperature TWE to a temperature T A , thereby ensuring the desired recrystallization state of the rolling stock at the end of the hot rolling line over the strip thickness.
