Definitions
- a cold-rolled strip is recrystallized annealed, then hot-dip coated and then dressed and / or stretch-bending.
- a hot strip which was previously dip coated, is reduced to dimensional stability on a separate cold rolling mill.
- a hot strip is hot dip coated after the removal of the Zundems and trained and / or stretch bending.
- 6,761,936 B1 WO 01/011099
- A2 a method for hot-dip galvanizing hot-rolled steel sheet is already known, wherein in a first step the strip is introduced into a pickling station, in a further step the strip is inserted into a strip Rinsing station is introduced, then introduced into a drying station, introduced in a further step in a galvanizing furnace and a galvanizing is carried out, wherein the aforementioned method steps are carried out under hermetic seal against air and oxygen from the environment.
- the object of the present invention is to further process the strip directly in the process line during the production of such hot dip-finished hot strips and to subject it there to a specific thickness reduction.
- the present invention thus relates to a process for hot dip galvanized steel strip, wherein the steel strip passes through a pickling station, a rinsing station, a drying station, a heating furnace and then a molten bath, characterized in that the finished thickness and the thickness tolerance of the hot dip coated steel strip are controlled Thickness reduction is achieved in a rolling stand in the process line, in which by at least one thickness gauge in the outlet of the rolling mill, the achievement of the finished thickness is controlled and deviations from this up or down as a control signal to the employment of the rolling stand are returned to increase the thickness reduction accordingly or reduce.
- the hot dip coated strip is subjected to elongation in the line and thus to a reduction in thickness in a skin pass mill, in which the goal of uniform elongation of the strip cross section over the strip length is pursued.
- the inlet and outlet speeds are measured and evaluated as a measure of a uniform extension or thickness reduction for control purposes.
- the technological emphasis in the method according to the invention in the targeted and controlled setting of the finished thickness and the tolerance in the roll stand in the line after hot dipping.
- tempering lies in the fact that e.g. as the run-in thickness increases, the reduction in thickness in the rolling mill increases to maintain the finished thickness, thereby increasing the run-out speed (at a constant run-in speed).
- thinner inlet thickness e.g. as the run-in thickness increases, the reduction in thickness in the rolling mill increases to maintain the finished thickness, thereby increasing the run-out speed (at a constant run-in speed).
- thinner inlet thickness e.g. as the run-in thickness increases, the reduction in thickness in the rolling mill increases to maintain the finished thickness, thereby increasing the run-out speed (at a constant run-in speed).
- thinner inlet thickness at a constant run-in speed
- the aforementioned thickness gauge is sold, for example, by the Thermo Electron (Er GmbH in Erlangen under the name Radiometrie RM 200 EM together with the corresponding software and hardware. These gauges are preferably used in line directly behind, and in particular also in front of, the hot rolling mill to control the rolling force for the thick reduced hot dipped hot rolled strip.
- a thickness gauge is arranged in front of the roll stand, which measures the input thickness of the steel strip and reports the thickness control of the roll stand.
- the thickness reduction is in a range of more than 2% to 30%, preferably 4% to 10%. With such thickness reductions, the thickness tolerance relative to the center of the band is +/- 0.01 mm, or better. According to a preferred embodiment of the present invention, the thickness reduction takes place after cooling of the steel strip to 25 0 C - 55 0 C, in particular 30 0 C - 50 0 C.
- a steel strip in the sense of the present invention is understood to mean e.g. hot rolled mild steels for cold forming, as used in DIN EN 10 111 under the designations DD11 - DD14, as well as hot rolled unalloyed structural steels, as described in DIN EN 10025.
- strip accumulators are provided before and / or after the roll stand in order to absorb speed fluctuations through the thickness control.
- These are, in particular, mini-band memories, in which the corresponding speed fluctuations can be absorbed particularly well.
- At least one of the work rolls in the roll stand is smooth or has a structured surface with a special cut and / or stochastic / deterministic structure.
- both a cylindrical grinding, as well as a spherical grinding can be used.
- stochastic structures For the production of rough surfaces on the steel strip on the one hand stochastic structures can be used, which by the methods Shot Blast Texturing (SBT), Electro Discharge Texturing (EDT), Electro Chemical Texturing (ECT) and Precision Texturing (PRETEX® process from Salzgitter AG) Furthermore, laser texturing (LT) and electron beam texturing (EBT) can be used to generate deterministic crater-like structures on such work rolls.
- SBT Shot Blast Texturing
- EDT Electro Discharge Texturing
- ECT Electro Chemical Texturing
- PRETEX® process Precision Texturing
- LT laser texturing
- EBT electron beam texturing
- the thickness reduction takes place in the presence of a rolling fluid.
- a rolling fluid is either a volatilizing metalworking agent, demineralized water, Synthetic rolling oil, but also to a rolling emulsion, which improve the friction properties in the nip (friction conditions between rolling and rolling).
- Such lubrications are usually carried out by a quantity order of about 0.2 g / m 2 - 5 g / m 2 .
- the hot-dip coating is a coating with a zinc or aluminum alloy.
- a zinc or aluminum alloy Exemplified are zinc, zinc-iron, zinc-aluminum, aluminum-zinc or aluminum-silicon, with zinc and zinc alloys being preferred.
- the pickling station, rinsing station, drying station and the molten bath pass through under shielding against air and oxygen.
- the object of the present invention is further to provide a plant for producing a special hot-dip coated hot-rolled steel strip.
- the present invention therefore relates to a plant for the production of hot-dip coated hot-rolled steel strip of the type described, comprising a pickling station, a rinsing station, a dryer, a heating furnace and a molten bath, characterized in that in the process line a rolling stand with at least one thickness gauge in the outlet is provided for a controlled reduction in thickness, preferably to provide a thickness reduction of more than 2% to 30%, in particular 4% to 10%, optionally in conjunction with an embossing with special grinding and / or stochastic / deterministic structure of the steel strip.
- a hot-rolled soft steel for cold forming under the designation band EN 10111 -DD 11 was subjected to a controlled thickness reduction of about 6.5% following a hot-dip coating of the abovementioned type according to the invention.
- the soft product EN 10111-DD11 is used to produce a galvanized grade steel such as DX51D of EN 10327 or S320GD of EN 10326 with the same material characteristics as a galvanized steel strip of the same designation in accordance with the EN standard. During the controlled reduction in thickness, the calipers were recorded over the tape length of hot strip coils.
- Example 1 was repeated, but instead of a controlled reduction in thickness, a 1% treatment was carried out. As in Example 1, the thicknesses were recorded over the tape length of hot strip coils.
- a comparison of the characteristics shows that the thickness letters over the strip length of hot strip coils in the trained state on the one hand (prior art) and in the inventive method on the other hand significantly different from each other and the process product according to the invention at almost 6.5 times higher thickness reduction, a hot strip coil with much lower Thickness tolerances is generated.
