Research and Optimization for transverse thickness difference control strategy of UCMW cold tandem mill Lubing Wang 1,2, a, Linjing Yan 1, b, Anrui He 1, c , Guanglin Li 2, a 1 University of Science and Technology Beijing, china 2 Hebei Shougang Qian’ An Iron & Steel CO., LTD, china austb_wlb@126.com, b yljustb@126.com, charui@ustb.edu.cn Keywords: transverse thickness difference; UCMW; edge drop Abstract.
Because raw material cross-sectional contour is complex and changeful, original control system has principle limition, some phenomena appear in actual production, variety value is in set range for edge drop △h15 – 115, but transverse thickness difference is not controlled in set range.
Complex profile genetic of material Original edge drop control system only has two assessment points, can not give reasonable evaluation and control with complex contour edge.
This phenomenon usually appears in raw material convexity or steel hardness is higher, as shown in Fig.3.

The ease of transformation, from cutting and/or punching to bending, welding, etc. together with the possibility of selecting different materials, thicknesses, finishes and the consequent reduction in weight while maintaining structural rigidity (or with minimum loss of mechanical properties) have allowed an extensive use, not only in automotive and aerospace products, but also in large and small appliances, furniture, etc.
This helps to check that there is no lack of material and, furthermore, to validate the design.

The conductive medium of heat is usually liquid of some special functions mixed with other materials which are determined by the actual working conditions, heat exchange between heat and cooling liquid occurs when the mixture flows around the inner channel of heat sink.
On the other hand, thermal performance of heat sink will be influenced by the heat conduction damping of metallic material, especially the maximal temperature rise of heat source [7].

Introduction Coal-based alternative jet fuels refer to the liquid fuels obtained from solid coal, using coal as raw material.
Using the coal as raw material, SASOL from South Africa obtained the semi-synthetic jet fuel (SSJF) and fully synthetic jet fuel (FSJF) via the F-T process.
