Products SPM - SKIN PASS MILL The pickled, cold rolled and tempered materials are processed in this line to improve mechanical properties (erosion of the irregular flow), high surface flatness and roughness before being shipped to the end user. Hot rolled materials, which have been cleaned with acid only next to annealed and cold rolled sheet ...
Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass. Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled. Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction.
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

Skin Pass Mill (SPM) Automatic packing improves packing consistency, aesthetics, quality and annealed coil to restore the desired temper and prevent generation of stretcher strain and coil breaks. Skin pass rolling also helps to produce the desired surface roughness (dull, …
INLINE SKIN-PASS MILL FOR COLD STRIP Skin-pass mills can also be installed directly "inline" in the exit section of an annealing or hot-dip galvaniz-ing line. The strip can be completed in the process line, and this has several advantages. The effort and expenditure on coil handling is reduced, enabling pro -
The plant is also equipped with Bell Furnaces and Skin Pass facility to cater the market for Domestic appliances. Jindal's Cold Rolled Steel is accredited with ISO 9001-2008 and having a valid license of Bureau of Indian Standards, like IS 277.
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 ...
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.
Skin pass mill is used for tempering the cold rolled steel coils in order to enhance strip flatness and to improve mechanical characteristic such as deep-drawing characteristic of the strip steel. a skin pass mill mainly consists of a pay-off reel, "s" rolls before and after mill. we can provide 2-high and 4-high temper mill.

Skin-pass rolling (or temper rolling) is usually the final process in the production of cold-rolled steel sheets. One of the main objectives in skin-pass rolling is to obtain a certain surface roughness profile. In this paper, the mechanism of roughness profile transfer in skin-pass rolling is investigated by experimental rolling tests as
SMS group - Website Plants All Plants Skin pass mill Skin-passing hot strip. Designs for hot and cold rolled strip Skin-passing hot strip. Skin-passed hot strip offers you these advantages: Most importantly, this process helps you attain perfect strip flatness. It also harmonizes the yield points and prevents the flow and break lines that can ...
Oct 31, 2012· The influence of skin pass rolling on tensile and microstructural properties of three industrial grade steels was investigated.
