Strip cooling is an important metallurgical process in hot strip mills. That''s why SMS group systems come with high cooling rates, flexible cooling strategies, and a powerful cooling model. To achieve a wide range of cooling rates, SMS group established different strip cooling system modules ranging from 35 to 200 m#179;/ (h*m#178;).
The socalled selective roll cooling is applied mainly for cold rolling mills to control the asymmetrical flatness deviations the strip width. There are furthermore across applications for special castrolling mills for narrowgauge hot strip production. Normally, two rows of nozzles are used in one header.
GENERAL ASPECTS OF ROLL COOLING FOR HOT amp; COLD ROLLING MILLS
May 18, 2007 Siemens Metals Technologies is now offering rolling mill operators a complete package of solutions for strip cooling in hot rolling mills. Microstructure Target Cooling includes a process model, automation and closedloop control systems as well as mechanical components such as
The cooling apparatus of the present invention is for cooling of an upper work roll of a rolling mill stand as well as a strip of metal being rolled in the mill stand. The rolling mill stand has...
#0183;#32;Optimum roll cooling in hot and cold rolling mills In the metalworking rolling process in hot and cold rolling mills, heat is generated by friction and deformation in
Today, cold and hot strip mills around the globe are continuously looking for ways to increase their productivity, save energy, lower their overall costs and improve the final quality of their products. Using lubricant in cold rolling and controlling the rollwear in hot rolling
#0183;#32;Work roll thermal expansion (crown) plays an important role in controlling strip profile and flatness of the strips. This can be done with a perfect and controllable cooling system which also takes care of the work roll against damage induced by fire cracking.
An apparatus for cooling an upper work roll of a rolling mill stand and a strip of metal being rolled has a header to supply a coolant fluid to the work roll and a stripper with a wiper blade that contacts the surface of the work roll between the header and the strip of metal.
Primetals Technologies have been a pioneer in the field ever since we developed the world''s first system capable of roll grinding inside the mill stand (ORP), and have enhanced this technology based on our extensive experience in the industry. Extending the roll life Eliminating roll surface defects Extending the length of samewidth rolling

cooling system. Problems of this kind can never really be calculated but they have a detrimental effect on all rolling schedules including stresses in the roll. As regards abnormal rolling conditions which are more or less very normal for rolling mills roll damage often occurs with consequences for the mill and the rolled product.
The cooling apparatus of the present invention is for cooling of an upper work roll of a rolling mill stand as well as a strip of metal being rolled in the mill stand. The rolling mill stand has upper and lower work rolls through which a strip of metal is passed to reduce the thickness thereof, and a cooling device for cooling the lower work roll.
