Hot rolling is not a good application as chrome begins to soften at about 300 C. Chrome thickness is also a factor depending of causes for roll failure. If wear is the only problem 0.001-0.002 is OK, but if you have frequent accidents with cracks or spalls chrome could make it worst due to its tendency to greatly reduce fatigue strength and ...

Universal foil rolling mills for all strip thicknesses from 0.7 mm to 0.006 mm for a wide range of rolled products Specialised foil rolling mills for foil rolling lines for graduated strip thicknesses. Specialised foil rolling mills come in three types
GENERAL ASPECTS OF ROLL COOLING FOR HOT amp COLD ROLLING MILLS BY HUBERTUS WENIG ABSTRACT . The paper describes how heat is generated in the roll gap and how roll cooling should , be applied on therolls in the best manner. In many cases roll cooling goes along with lubrication. The characteristics of the various coolants used for roll cooling are
The Aluminum Association has used its best efforts in compiling the information contained in this book. While the Association believes that its compilation procedures are reliable, it does not warrant,
The majority of cold and foil rolling operations use oil-based lubricants, although some mill systems can accommodate water-based alternatives. The base oil represents more than 90 of the total lubricant volume and acts as a solvent for the load bearing additives and a roll-cooling medium.

Jan 21, 2019 Cold 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.

If you search the Internet for what a cold-rolling mill is, one might be hard-pressed to find a description to relate to and understand. It is important to preface that what is involved in the process of re-rolling aluminum coil or strip is quite capital intensive, which explains why there are limited mills in the United States that will flat roll aluminum coil.
An easy and practical method how to check the nozzle footprints on the roll is the grease test figure 1. The rolls are covered with a layer of grease, the roll set is 4 installed in the mill and the sprays are activated for a short time. After removing the rolls out of the mill, the nozzle footprints can be visualized.
Oct 07, 2019 How to Distinguish between Cold Rolled Aluminum and Hot Rolled Aluminum Firstly, it can be judged by visual inspection. Generally, the surface of the hot rolled aluminum sheet is brighter. Secondly, the elongation can be tested. Generally, the elongation of the hot rolled aluminum plate is higher than that of the cold rolled aluminum plate.
