水基石墨润滑技术在铝板带铸轧生产中的研究与应用OA

With the further improvement of the requirements for the surface quality,microstructure and mechanical properties of aluminum alloy cast-rolled strips,coupled with the development needs of low-carbon aluminum,the application of water-based graphite lubricants in the roll release technology of aluminum cast-rolling mills has become increasingly significant.The principle of roll release using water-based graphite lubrication was briefly outlined,and the effects of water-based graphite lubricants on the temperature of casting roll surfaces,the surface quality of aluminum sheets and strips,grain structure,and central segregation were investigated through experimental studies.The results indicate that water-based graphite lubrication can accelerate heat dissipation from the casting roll surface and cooling of the sheet and strip,thereby enhancing the speed of cast-rolling.It promotes the formation of a cold zone in the aluminum sheet and strip,inhibits grain growth,and improves the mechanical properties of the product.Additionally,it reduces carbon emissions,exhibiting greater environmental friendliness.
