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 coil-to-coil temper pass mill or in line on a cut-to length line.
A temper mill is a steel sheet or steel plate processing line composed of a horizontal pass cold rolling mill stand, entry and exit conveyor tables and upstream and downstream equipment depending on the design and nature of the processing system. The primary purpose of a temper mill is to improve the surface finish on steel products. Components
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.

Jul 08, 2019· 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.
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 customer's 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.
A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.
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.
Recoiling provides a better coil shape. Included in the process is cutting off the head and tail ends of the strip as well as the off- gauge materials. To safely handle today's new materials – especially high- strength steels – the hot strip skin-pass mill (HSPM) comes with technology designed for materials with the "spring effect".
