The mill stand can be work roll driven or back up roll driven. The mill can be designed with hydraulic work roll bending or back up roll bending. Installations typically have a single rolling mill stand, but may have two. Pinch rolls provide back tension for the pay off reel in the entry section and entry and exit tension for the temper pass.

The wet temper rolling procedure(1) is generally adopted to provide better shape, lubricity, and antirust and cleanliness pro perties on the surface quality in comparison with the dry rolling procedure. The original wet temper rolling chemical RL1A with lower antirust property in the temper mill was applied to provide acceptable lubricity.

Tension. The tension applied to the strip also influences the rolling pressures developed within the bite. Higher entry tension lowers the starting point on the friction hill and so needs to be taken into account in the rolling model. Further learning. In summary, the calculation of rolling force is a complex and multidisciplinary calculation.

Abstract The tension modes of coldrolled strip coiling are analyzed. The dependences of the stressstrain state of the coils on the strain degree, temperature, velocity, strip rolls surface roughness during cold strip rolling are considered. Coiling methods provide improvement of production efficiency and the quality of coldrolled sheet steel by preventing the appearance of such rolling ...

Tandem cold rolling process is a nonlinear complex system with external and internal uncertainties and significant disturbances. The improvement in the quality of the final output depends on the control strategy of centerline thickness and interstand tension. This paper focuses on interstand tension control problem in 5stand tandem cold rolling mills. Tension dynamics can be described by a ...

This is article is part 1 of a fourpart series covering flatness and stability in cuttolength, slitting, and tension leveling operations. This article covers how flat rolled metal gets unflattened, including the 3 categories of defects, how defects are created at hot and cold mills, and how coil processors also create defects.

What Is Temper Passing? Temper passing is compressing flat steel under very high pressure between two work rolls to flatten and elongate it (see Figure 2).A cold reducing process, temper passing (also called temper rolling or temper pass) strives to decrease the material thickness between and 2 percent (alternatively, elongating the coil to 2 percent) without appreciable spreading, or ...
