Steel strips that were heated in the batch annealing section receive additional treatment in the skin-pass. The cold rolling mills are also equipped with shearing lines that cut the coils on length and width. In our inspection lines we are able to additionally check the sheets surface. If needed we can bring the coil to a certain weight .
Why Skin Pass Mill is necessary for Hot Strip Mill Lots of necessary functions 1. To get good shape flatness 2. To prevent coil break 3. To get smooth surface 4. To adjust coil tonnage to customers demand 5. To discard the scrap and secondary portion 6. To inspect coil surface Generally there isnot a hot strip mill without a skin pass mill.

the skin pass mill and then introduces the developed technology and describes its validation by examples of numerical simulation and actual mill tests. 2. Outline of Skin Pass Mill 2.1 Role of Skin Pass Rolling and 4SKP The skin pass mill is an important rolling equip-ment for building quality into products and has the
Skin pass or temper mills can be designed with a pay-off and re-coiler group a centering device entry and exit bridles for tension adjustment anti-flutter and anti-crimping rolls respectively a 2-high or 4-high mill stand with quick roll changing bending blocks automatic pass line adjustment fully hydraulic screw-down cylinder system and a state-of-the-art control system with an advanced process model.
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.
2.2 Dry and Wet Skin Pass Rolling The Skin Pass Rolling provides the finished surface of the steel. Clean conditions for the mill and best possible prevention of dirt in the roll gap are required. In many cases the mill is working successful with wet skin passing agents which even keep
Cold roll coil further processs for slitting after skin pass on C.R. Slitter as per requirement coils are slitted slitting size limit are minimum 30mm width. Cut to Length If steel strip is requirement of customer coils are send to cut to length machine here coils are cut as per require length
Oct 08 2014 Fig 1 Typical schematics of a 5 stand tandem cold rolling mill Temper rolling or skin pass rolling of annealed strip Cold rolled coils after removed from the annealing furnace are in their dead soft condition and are therefore undergo a skin pass rolling or temper rolling in a skin pass mill.This involves a controlled light reduction of the cold rolled steel sheet and is carried out due to the .
In skin pass rolling with dull work rolls of large diameter com-parable to those used in commercial-scale skin pass rolling mills it has been previously reported 1 that rolled plates exhibit minute elon-gation of less than 1 even when rolling force is so large that elon-gation of approximately 10 occurs in case of rolling with bright work .
May 18 2018 Skin-pass rolling or temper rolling is the final operational step in the production chain of hot-rolled strips and its main role is to apply a small deformation to the hot-rolled strips cooled to room temperature to improve the shape quality and mechanical properties. Because of the absence of rolling lubricants between the work roll and strip as well as the existence of obvious oxide layer .

NIPPON STEEL ENGINEERING CO. LTD.s 4Hi skin-pass mill is a robust facility with high levels of mill rigidity. Our proprietary rolling control position control and auto force control and texture control technologies also enable a high-quality strip surface appearance to be obtained stably. In addition work roll cleaning is performed using .
A special feature of tinplate production is the second rolling step for thickness reduction after annealing. Running parallel to this is a temper rolling process that prepares the strip for further surface finishing and coating. Our twin-stand double cold reduction mills DCR combine reduction rolling and skin-passing in a single mill.
Skin-pass rolling is often the final forming step in the production of cold rolled steel sheet 1 and it is applied to either eliminate upper and lower yield stress behavior yield point elongation or to improve the surface of the strip or both 2. The main effect of skin pass rolling is to create mobile dislocations and not to reduce the .

Coil break rejection at Hot Skin Pass Mill PT Krakatau Steel is a repetitive claim from consumer and target of quality objective is still out of target. Coil break is surface defect of hot rolled coil with appearance of surface looks some areas of small lines transverse to rolling direction low contrast to surface white or black lines.
In general the skin pass line of a hot rolling mill cools a hot rolled hot coil in a cooling station and then supplies it to a side conveyor with a crane to correct the shape of the strip while passing through a pair of rolling rolls. To do this hydraulic cylinders are installed at both sides of the lower side of the roll roll chocks namely .

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 Pass or Skin Pass Rolling. Material can be reduced accurately while skin passing. Hot rolled steel coming from a steel mill or pickle line may need to be reduced 1 to 2 in thickness. This can be done on a coil-to-coil temper pass mill or in line on a cut-to length line.
The skin pass mill is the final rolling process for building quality into products. The strip is rolled at an elongation rate of a few percent in the rolling direction while predetermined tensions are set to the entry and exit sides of the mill to improve flat-
