The heart of the temper mill is the cold rolling mill stand which produces the temper pass. It will include electric powered drive motors and speed reduction gearing suited to the process desired. The design of the rolling mill can be a 2-high or 4-high (even 6-high in some cases). The mill stand can be work roll driven or back up roll driven.

조질압연(Skin pass temper rolling) 조질압연을 하는 조질압연기(skin pass mill temper rolling mill)에는 2중 또는 4중식 회전압연기가 있으며 석도강판 원판용 등

Temper / Skin Pass Mills The device uses skin pass rolling to improve the mechanical properties and surface texture and improve flatness in order to form materials such as hot-rolled steel sheets cold-rolled steel sheets stainless steel plates and aluminum plates into final products.

Oct 31 2012 · The influence of skin pass rolling on tensile and microstructural properties of three industrial grade steels was investigated. Skin pass rolling was performed on a laboratory mill equipped with a device designed to reproduce the effects of sheet tension and with load cells aimed at measuring the main working parameters.

Roll change cars for all skin-pass mills. The modern design of this system allows rolls to go through the mill stand or side changing system depending on specific needs. Combined with a fast roll changer car this design is the ideal system for a fast and effective roll change and is particularly well adapted to in-line DMS SkinPass mills.

The hot-rolled strip skin-pass mill is the important technological equipment of finishing process in the hot rolling plant and its role is to apply a slight thickness reduction of approximately 1 4 to the finished products cooled to room temperature to repair flatness defects and improve the surface quality and mechanical properties. In this study the initial flat roll contours were

Temper Rolling (also called skin pass rolling or dressing) in engineering a finishing operation in the production of thin strips of steel and nonferrous metals. It consists of cold rolling with very low reduction of area (not more than 3 percent). As a rule the metal is subjected to temper rolling after heat treatment. Temper rolling increases the

skin pass rolling a stretching that is applied using a tension leveler and a compression applied from rolls. As it was not possible to apply the stretching load on labora-tory skin rolling a separate set of samples set C was imposed on a different amount of reductions using an industrial skin machine to investigate the effect of the real

the same for skin-pass rolling and vertical indentation at the same load. For the large work roll (R250) the skin-pass elongation corresponding to the maximum value of the peak pressure on the abscissa is approxi-mately 2 . Roughness transfer in skin-pass rolling can Fig. 3 Roughness profile model of roll

Practically the all defects in cold rolling inspected before dispatching the material to the customer at skin pass mill. R C Inspection wings generally focused over four "S" i.e. Shape Size Surface and Safety during their inspection. Cold rolling improves the surface finish and holds tighter tolerances. This will certainly affect the quality
