Definitions
- the present invention relates to the descaling operation of a metal strip, in particular steel, scrolling during hot rolling before entering the milling or finishing cages of the rolling mill
- this operation is more commonly called “secondary descaling", as opposed to the "primary” descaling which intervenes on the steel slabs at the exit of the reheating furnace before rolling.
- secondary descaling of the steel strips is intended to rid the surface of the band of the so-called secondary scale, which is formed by rapid reoxidation of the hot metal during the stay of the strip in the open air after its primary descaling on leaving the oven. It thus intervenes doubly during the rolling, first before the entry of the strip in the roughing, and before entering the finisher rolling mill.
- the secondary scale is generally in the form of an adherent layer of metal oxides, typically between 50 and 100 microns thick, rather irregular in appearance.
- the secondary descaling is successful when it provides at the entrance of the finisher a steel strip having on the surface a uniform layer of residual scale of 20 to 30 microns thick just beyond, to avoid encrustations of oxides on rolling rolls.
- the descaling operation consists schematically in impacting the surface of the moving strip by powerful water jets delivered by spray bars placed at a short distance and provided with injection nozzles fed under high pressure, typically above 130-150 bars, or even more than 200 bars in some cases. It is thus intended to combine a thermal effect (the surface temperature of the strip, around 1100 ° C. at the inlet of the descaling, drops almost instantaneously to nearly 600 ° C.) with a mechanical effect due to the large quantity of movement of water jets at impact to crack the scale and eliminate the surface by the effect of hunting.
- a thermal effect the surface temperature of the strip, around 1100 ° C. at the inlet of the descaling, drops almost instantaneously to nearly 600 ° C.
- This operation is conventionally carried out in a descaling box, about 1 to 2 m long, placed some 5 m upstream of the finishing cages, crossed by the steel strip in rapid rectilinear scrolling and sheltering the upper irrigation booms and lower ones with nozzles inclined counter-current of about ten degrees.
- the object of the invention is to provide an immediately operational response to the question of reducing the costs of the secondary descaling operation, that is to say a response compatible with a simple reorganization of existing equipment, so without necessarily involve the relocation of a new complete secondary descaling equipment.
- the subject of the invention is a method for the secondary descaling of metal strips, in particular steel, in scrolling during their hot rolling by spraying water at their surface by means of watering ramps.
- nozzles fed with pressurized water characterized in that the nozzles are fed under low hydraulic pressure, not exceeding 30 bars (and preferably below 10 bars, but not less than about 3 bars), and that, in order to ensure a thermal effect of the water sprayed on the surface to be de-scaled quantitatively similar to the thermal effect obtained with the known method of known secondary descaling at high pressure (ie a cooling of the band which lowers the temperature of its oxidized surface at 600 ° C.), the said nozzles are dimensioned so that they deliver a surface water flow rate on the strip similar to the surface water flow delivered by the said high-press method. ion.
- the surface water flow rate is greater than 2500 l / min / m 2 and advantageously 7500 l / min / m 2 .
- the invention also relates to a method of secondary descaling of metal strips, in particular steel, in scrolling during their hot rolling by spraying water at their surface using nozzle irrigation booms fed with water under pressure, characterized in that the nozzles are fed under low hydraulic pressure, not exceeding 30 bars, and in that, in order to ensure a thermal effect of the water sprayed on the surface to be descaled quantitatively similar to the thermal effect obtained with the usual known high-pressure secondary descaling method, said nozzles are adjusted so that the density of the heat flux extracted from the band (EfF) resulting from the cooling of its surface by the projected water is similar to that performed with said known practice at high pressure.
- the heat flux density extracted from the (HF) band is between 6.5 and 20 MW / m 2 for a strip temperature between 900 and 1100 ° C.
- the heat flux density is between 10 and 11 MW / m 2 for a strip temperature between 900 and 1100 ° C.
- the process according to the invention can also comprise different characteristics, taken alone or in combination: the nozzles are fed with a hydraulic pressure of less than 10 bars, without however going down below 3 bars,
- the process of the invention is carried out upstream of the finishing stands of a hot rolling mill of steel strips,
- the process of the invention is carried out upstream of the roughing cages of a hot rolling mill of steel strips.
- the invention also relates to a secondary descaling equipment for moving metal strips, in particular steel strips, comprising watering ramps provided with water jet nozzles on the surface of the strip, characterized in that it comprises a "low pressure" water supply unit of said nozzles of the watering ramps.
- the invention is based on the discovery that it is even more the thermal effect of the jets of water on the cooling of the oxide crust which acts in favor of the secondary descaling that their mechanical effect on the fragmentation of this oxide crust on the surface of the strip, or, in other words, the effect of "high-pressure cleaning" of the powerful jets on their impact, as previously thought.
- thermo effect of cooling and “thermal efficiency” are equivalent. They express the fact that, during the brief residence time of the strip in the descaling box (of the order of one second only), it is a question of ensuring a fall of the temperature of the oxide layer up to about 600 0 C, whatever its temperature at the entrance of this box. It is known that the underlying physical quantity, and ordinarily measurable on a rolling train, is the extracted caloric flux density.
- FIG. 1 is a plot of curves, called boiling curves, resulting from the experiment and showing, as a function of the surface temperature of the strip, the comparative thermal efficiency of a secondary descaling before entry to the finisher conducted with different projected water hydraulic pressures. This thermal efficiency is quantitatively translated in ordinate by the surface density of extracted heat flux (HF), given in MW / m2 of metal strip surface;
- HF extracted heat flux
- FIG. 2 shows the efficiency of this secondary descaling, in terms of the residual thickness of the calamine layer in microns (e c ) in a surface temperature range of the descaled steel strip (900-1050 ° C. ) deliberately chosen according to the inlet temperatures in the finishing cages.
- the reference curve is curve A.
- This curve A results from a conventional secondary descaling carried out using powerful water jets coming from nozzles fed at 130 bars of pressure.
- the other two curves B and C are representative of "low pressure" jets of 8 bars each, one (curve B) resulting from tests carried out with a flow rate of water equal to that of the curve A to jets "high pressure", namely 7,500 l / min / m 2 , the other, curve C, resulting from tests conducted with a significantly lower surface flow rate: 1500 1 / min / m 2 .
- the criterion for setting a successful "low pressure” secondary descaling according to the invention lies in the maintenance in the oxide layer of a thermal effect similar to that conventionally achieved with jets "high pressure” (curve A). This must ultimately result in a drop in the temperature of the blank 20 to 100 0 C (depending on the grade of steel to be rolled) between its entry into the watering box (typically about 1100 0 C for a carbon steel for example) and its entry into the finishing cages of the mill (typically 1030 0 C approximately).
- This thermal effect which is thus expressed by a high rate of momentary cooling of the surface of the strip (several hundred degrees / sec) has been expressed, for the parameterization of the three curves of the graph, by a classically accessible physical quantity. from the measurement, namely the density of heat flux extracted from the product being rolled by the projected water (Heat Flux in English abbreviated, or HF), magnitude expressed in MW / m 2 .
- this characteristic quantity is particularly suitable for dimensioning a plant.
- the descaling because it is correlated to the cooling water flow rate per m 2 of strip (the surface water flow), which is a parameter that can easily be obtained from the definition of the operation of the descaling: schematically, at a value of HF corresponds a surface flow rate of cooling water.
- the HF of the "High Pressure" descaling of reference (curve A) was kept constant around 10 MW / m 2 all along the watering operation (surface temperature ranging from 1100 to 600 0 C).
- Those of the "low pressure" descaling according to the invention were maintained respectively over the same temperature range between 10 and 18 MW / m 2 in the experimental case representative of curve B and between 6 and 10 MW / m 2 for the case. of curve C.
- the HF value is actually calculated from data specific to each descaling equipment that are, to mention only the most important, the temperature of the cooling water (here at 20 0 C for all tests) , the type of projection nozzles, the water outlet pressure of these nozzles, the distance separating the nozzle nose of the surface of the band to be descaled, as well as the opening angle of the jet at the outlet of the nozzle.
- the low-pressure curve C which displays a significantly lower HF (slightly less than 7 MW / m 2 ), reflects a correlatively lower quality of descaling.
- the descaling according to the invention can be carried out for a heat flux density extracted from the product of between 6.5 and 20 MW / m 2 and, when referring to the flow rate of surface water, for a flow rate higher than 2500 l / min / m2.
- the required HF levels (of the order of 10 MW / m 2 ) could no longer be achieved, except to multiply the watering ramps, but with the risk nevertheless of not being to be able to ensure the thermal contraction effect of the oxide crust necessary for its unhooking of the metal support surface.
- the invention can be easily implemented by operating with pumps supplied at low pressure, thereby saving energy and reducing maintenance costs, provided that the conformation of the nozzles is adapted as necessary. to ensure a flow of surface water equivalent to that which would have been practiced in high pressure configuration.
- nozzles used for the implementation of the method of the invention will be arranged at the same distance from the strip as the distance applied during the known descaling process at high pressure.
- Other additional advantages of using low pressure ramps in place of high pressure to achieve secondary descaling will be noted, such as:
- the invention can not be limited to the examples described above, but applies to multiple variants and equivalents.
- it is recalled that it relates to any form of secondary descaling, that is to say removal of calamine previously formed by hot oxidation of a metal surface in contact with the ambient air.
