The contoured rolls will have half the shape of the section on each roll pairs. When assembled in the mill complete cross section is obtained. To control the lateral spread of the work it is turned through 900 after each pass before entering the next roll. The work passes through a series of such grooved rolls till the final size and shape is ...

cerning dull work roll rolling 2–4) has, however, succeeded to explain quantitatively this peculiar elongation behavior with dull work roll skin pass rolling. Furthermore, in dull work roll rolling, realization of prescribed surface roughness of rolled plates are also important as well as giving prescribed elongation to rolled plates.

To minimize the roll diameter a fourhigh or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness, which is overcome using backup rolls. These backup rolls are larger and ...
Jul 08, 2013· Fig 1 Texture of galvanized iron sheet. Process of galvanizing. The process of galvanizing steel sheet was developed simultaneously in France and England in 1837. Both of these methods employed a ''hot dipping'' process to coat steel sheet with zinc. Galvanizing is carried out on cold rolled sheets/cold rolled strips.

Tags Pickle Lines, Rolling Mills; 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 coiltocoil temper pass mill or in line on a cutto length line.
for all hotdip galvanized articles, and ISO 1461 is the standard most commonly used in Europe. In all cases, the inspection of hotdip galvanized steel is conducted at the galvanizing plant prior to shipment of the product. The requirements for hotdip galvanized coatings are found in three ASTM specifications;
Oct 31, 2012· Abstract. 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.
the sheet thickness of the incoming sheet was varied depending on the particular skin pass level and the final roll gap was kept at 5 mm. (For Condition 3, an intermediate skin pass with a larger roll gap was included). After skin passing, the distribution of the longitudinal residual stress, σx was determined over the sheet thickness, as shown in
