Detailed Project Report on cold rolling mill for stainless steel (4 hi mill to use hr coils)

COLD ROLLING MILL FOR STAINLESS STEEL
(4 HI MILL TO USE HR COILS)
 [CODE NO. 3194]  


A finished stainless steel product such as sheet or strip which has been wound or coiled after rolling. Is called SS coil. SS coil are manufactured by cold rolling mill.ss coil includes SS sheet and SS strips.

Stainless Steel Coil such as Stainless Steel 202 Coil, Stainless Steel 304 Coil, Stainless Steel 304L Coil,Stainless Steel 904L Coil, SS Coil 301, Stainless Steel 410 Coil are manufactured by ss.

Stainless Steel C.R. Coils/Sheets are being used for various Engineering purpose for shipping, dairy,chemical, aviation, Defence, Hotels, Building, Industries

In cold rolling, the properties of hot rolled coil products, e.g. thickness, mechanical and technological characteristics, are changed by compression between rollers without previous heating of the input. The input is obtained in the form of coils from hot rolling mills. The processing steps and the sequence of processing in a cold rolling mill depend on the quality of the steel treated.

The process route for high alloy steel (stainless steel) involves additional steps to that for carbon steels.

The main stages are: hot band annealing and pickling; cold rolling; final annealing and pickling (or bright annealing); skin pass rolling and finishing.

Cold rolled products are mainly strips and sheets (thickness typically 0.16 - 3 mm) with high quality surface finish and precise metallurgical properties for use in high specification products.
