بیشترRough rolling mills may have either two-high or four-high configuration. The strip temperature decreases in the rough rolling operation to about 1830ºF (1000ºC). Finishing rolling in a tandem four-high rolling mill (5-7 stands). The strip dimensions (thickness, width) are strictly controlled in this operation. ...
بیشترThe rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
بیشترCold rolling is a process that occurs after hot rolling in order to reduce the thickness, increase the yield and tensile strength and pliability of metal. It is a relatively expensive and labour-intensive process, but the improved mechanical properties increase the value of the finished product, whether that is a sheet, strip, or coil.
بیشترThe first Zoom-Mill™ was put into practical use and commercial operation started in March 2010. This mill is working very well as intended initially, achieving approximately 1% improvement of product yield of the products immediately after commencement of operation. Productivity of the mill was also sharply increased along quick learning curve.
بیشترThe same is shown in the flow chart. Classification of Rolling Process Rolling Process can be classified either i)based on the temperature of the metal during rolling or ii) based on the arrangement of the rolls and their number or iii)based on the Products rolled. i)based on the temperature: Rolling can be classified as Hot Rolling or Cold ...
بیشترIn hot rolling mills, premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the wear resistance and extend the service life of rolls.
بیشترnel. In those rare cases where the wrong steel goes through the rolling mill, inspec tion will usually spot such a mistake by the color of the hot steel or by the particular way it behaves during rolling or shearing. To eliminate further any possibility of a mix-up, additional laboratory spot tests are made from scrap material cropped from
