Current hot rolling lubrication, based on the use of emulsion (0.2 to 1mgr of oil mixed in water), causes many problems in term of control, consistency and reproducibility of the results and maintenance. The guaranty of a …

A new technology for lubricating the work rolls during hot rolling has been successfully tested in the finishing mill of ArcelorMittal Dunkirk. This new technology allows spraying very low quantities of pure oil on the work rolls to reduce the rolling forces by up to 20% and with an increased efficiency of 50% compared with emulsions.

Current hot rolling lubrication, based on the use of emulsion (0.2 to 1mgr of oil mixed in water), causes many problems in term of control, consistency and reproducibility of the results and maintenance. The guaranty of a high and constant quality of …

Hot rolling experiments have been conducted, using low carbon steel strips. The effects of water, oil/water emulsions, neat oil and dry conditions at the roll/strip surface, on the resulting loads and temperatures were examined. The 1 : 1000 oil-to-water mix appeared to lower the mill loads the most. Doubling the oil volume was found to have a ...

To reduce roll wear and chatter vibrations in its hot strip mill, Eko Stahl carried out roll gap lubrication trials. The trial equipment, the lubricant and the trials themselves are described. Rolling force and consequently electric energy consumption were reduced by 8 to 34 % . ... New lubrication technology for the hot strip mill Revue de ...

The application of a hot rolling lubrication has a positive influence on the hot strip properties at the strip surface and through that also on the mechanical features of the final product and that it is easily integrate-able into the overall mill control.

characteristics for silicon steel strip in hot rolling For hot rolling, the transverse thickness difference is about 20 lm. Quasi-rectangular section is used to characterize the good section shape of strip. The main principle of ARSC technology is as follows: the strip section tends to be rectangular in the whole hot continuous rolling pro-

Technically, the essence of profile and flatness control lies in the control of lateral roll gap in hot strip rolling process, ... The industrial application of this new contour technology shows the percentage, which strip head crown is within 0·05±0·02 mm, is up to 95·6% after being used on the upstream stands of the hot stainless strip ...

Aluminium rolling lubrication strongly influences both mill productivity and metal quality. The various rolling processes and lubricants are discussed here.

This new technology allows spraying very low quantities of pure oil on the work rolls to reduce the rolling forces by up to 20% and with an increased efficiency of …

An efficient way to increase the operational performance of hot strip mills is to lubricate the work rolls. A series of tests have been carried out at the hot rolling mill of Chertal (Cockerill-Sambre - Usinor). The main benefits which have been observed when using lubrication concern the reduction of friction and of rolling force.

From 1935 to 1936, animal oil began to be used to lubricate the roll on the section steel mill in the Soviet Union. In 1968, the hot strip rolling process was first applied to lubricate rolling in the United States. Subsequently, the research and application of hot lubrication rolling technology were also carried out in Britain and Japan.
