Abstract:
Coiling temperature, finish rolling temperature and running speed of ZSAC1 strip during U-type cooling and number of valves which had been turned on were analyzed in order to find out the reason of low coiling temperature at tail of ZSAC1 strip in U-type cooling process. Results of research showed that running speed of strip and finish rolling temperature were main factors affecting accuracy of coiling temperature. Coiling temperature decreased with the increase of running speed of strip. Coiling temperature fluctuation would occur at the same part of strip when finish rolling temperature increased or decreased. Holding rolling speed and rolling temperature of strip stably can improve accuracy of coiling temperature during downstream U-type cooling.

Abstract:
Down coiler is an important equipment of hot rolling mill. The coiling torque is changing constantly in the process of strip steel coiling, and the largest coiling torque depends on several factors, such as the material and specification of coiling strip, the coiling temperature and the process parameters and so on. Only when the largest coiling torque is less than the carrying capacity could the coiler work in security. A topology relationship of the largest coiling torque among the materials, the specification of the strip and the coiling temperature is established. Based on the BP(backward propagation of errors) artificial neural network, a predicted formula model of the largest coiling torque in coiling high strength strip is built, which provides a theoretical basis for the development and utilization of the largest working potential of the down coiler.

Abstract:
Coiling temperature of hot rolled strip is one of the important parameters which affect performances of hot rolled strip. The control of coiling temperature is highly nonlinear and time-varying. Based on the laminar cooling control system of a hot rolling plant, a coiling temperature prediction model based on BP neural network was established. Many factors which affect coiling temperature control were taken into account, and the BP neural network was trained by actual production data. The simulation was carried out, which indicates that coiling temperature can be predicted precisely, and the BP neural network model has the prospect of online application.

Abstract:
In order to improve the control accuracy of the coiling temperature of strip in the laminar cooling process when working condition is varying, an intelligent setting method of the cooling water volume is researched in this paper. The strip coiling temperature mechanism model is built firstly. Secondly, the key model parameters are identified with case-based reasoning (CBR) technology to improve the model accuracy. Lastly, the cooling water volume setting method based the model is proposed where disturbance input method is applied. The simulation result showed that the proposed method can improve the strip coiling temperature accuracy when the operation condition is changing. The strip coiling temperature accuracy can be improved due to the CBR technology which can adjust the key model parameters according to the varying operation condition. So, the setting values based the improved model are adjusted with the changing working condition, with self-adaptive ability.

A numerical model including thermal and microstructural model is established for precisely prediction of residual stress of hot-rolled strip on run-out table. Temperature and phase transformation fraction are coupled and formulated for the calculation of thermal and transformation expansion that could induce internal stress. Residual stress for hot-rolled strip before and after coiling are calculated using C++ program. Influence of edge masking on residual stress is analyzed. It is concluded that edge masking makes the strip flatness better after coiling.

Abstract:
The influence of the coiling temperature, ranging from 550 to 570°C, on the morphology and the phase composition of the oxide scale formed on the microalloyed low carbon steel for automobiles after hot strip rolling was investigated. Physicochemical characteristics of the oxide scales were examined and their formation mechanism was discussed. Thickness of the oxide scale is in the range of 8-11µm and decreases with a decrease of coiling temperature. The microstructure and phase composition, XRD analysis shows a large amount of magnetite (Fe3O4) and some sparse hematite (Fe2O3) exist on the surface of hot rolled strip when the coiling temperature reduces from 570 to 550°C. The coiling temperature substantially affects the internal microstructure and magnetite phase.

Abstract:
Based on optimization setup technology, an online adaptive calculation method for improving accuracy of strip coiling temperature control on the run-out table (ROT) has been developed and implemented in hot strip mill (HSM). Multi-objective control strategies, which include coiling temperature, middle target temperature and appropriate cooling rates have been finalised. Cooling strategies, elements tracking, and dynamic correction are employed in the control system. In addition, the model optimization and soft-measure method are also introduced in the study. Rolling tests with various grades of steel covering a wide range of thickness show that the developed model can improve the accuracy of coiling temperature control to obtain an uniform mechanical properties. Good correlation has been found between the predicted temperatures and the actual coiling ones.

Abstract:
In der vorliegenden Arbeit wird ein prozessübergreifendes Simulationsmodell für die Temperatur- und Gefügeentwicklung im Band und Coil beim reversierenden Warmwalzen entwickelt. In der Software werden die erstmals aufgestellten Modelle der Bandab- und aufwicklung implementiert. Die Temperatur- und Gefügeveränderungen im gewalzten Warmband werden lokal und prozessübergreifend betrachtet. Die für das gesamte Modell notwendigen Koeffizienten zur Beschreibung der Wärmeübertragung wurden mittels der inversen Methode bestimmt. Die Bestimmung der radialen Wärmeübertragung im Coil erfolgte mit Hilfe von Laboruntersuchungen in Abhängigkeit von der Temperatur, der Banddicke und des radialen Druckes. Die Validierung des Modells für die Temperatur- und Gefügeentwicklung erfolgte am Beispiel des reversierenden Warmwalzens der Magnesiumlegierung AZ31. Zu diesem Zweck wurden Versuche zu Temperaturmessungen in den einzelnen Phasen der Prozesskette durchgeführt. Die Ermittlung der Einflüsse der Umformbedingungen auf die Temperatur- und Gefügeentwicklung während des reversierenden Warmbandwalzens erfolgte abschließend mit Hilfe des entwickelten Modells. Die Ergebnisse zeigen auf, wie sich die Walzbedingungen auf die Entwicklung der Temperatur und des Gefüges auswirken.

Abstract:
A Mathematical model has been developed to predict the temperature profile of the strip during water-cooling on the Run-out Table (ROT) of the Hot Strip Mill (HSM). This work describes the development and implementation of the model at Tisco’s HSM. The model has been developed using Explicit Finite Difference technique to predict the coiling temperature (CT). The model has been implemented successfully after having been validated with the actual coiling temperature (CT) for several thousand coils. A number of grades of steel with various thicknesses have been tested with this on-line model and the agreement of actual CT with the predicted ones was found very good. The on-line model is used to calculate the cooling rates at different segments of the strip that are used to obtain microstructure and mechanical properties.

Abstract:
With increasing international competition in steel production mainly from developing nations, it is important for steel plants to keep up to date with new technologies, and continuously improve on current practices and manufacturing techniques to remain competitive. This paper looks specifically at improvements to the hot rolling mill downcoilers, which is where the strip is coiled at the end of the rolling process. Hydraulic and pneumatic technology is combined to give accurate position control of guide wrappers that aid the initial coiling process. The paper presents an experimental test rig, using an actual wrapper guide, constructed to evaluate the specific design approach.

Abstract:
The real challenge of achieving yield to tensile ratio (YR) lower than 0.85 along with YS & TS as per specification especially for ERW pipes was performed because the major concern with higher yield ratio is the resultant lower uniform elongation, lower work hardening exponent and also possible deformation under load (safety) when pipelines are used underground. A study was performed by controlling the HSM process parameters. To ensure tensile properties as per X60 grade with lower yield ratio, and good impact toughness, Finish Rolling Temperature (FRT), Coiling Temperature (CT) and Cooling Rate (CR) were varied at Hot Strip Mill in production scale. Generally, micro-alloyed steels show good strength as desired for X60 grade, along with high yield ratio up to 0.90 especially for lower thickness like 6.4mm due to thermomechanical rolling technology. The HSM process parameters for reducing yield ratio was focused on finding the effect of grain size and uniform microstructure. The results of coil form material showed that higher deformation temperature with normal CT and consistent water-cooling pattern could give optimum YS, TS with lower. YR. Comparatively, there was relatively high amount of change in YS, TS & YR with different combination of FRT, CT and CR. At customer end, after pipe making, it was found that yield ratio was lower than 0.85 with minimized YS drop due to Bauschinger effect. Interestingly, the tensile properties & yield ratio values were differing with respect to ERW pipe manufacturing methods (Cage forming & Linear forming processes). These were attributed to the differences in straining during pipe forming. The study indicated that API-X60 grade steel can be supplied with optimization of HSM process parameter to get desired yield and tensile properties as per specification with yield ratio of 0.84∼0.88 and also achieve desired yield and tensile results after ERW pipe making with yield ratio of 0.85 max.
