As the main choice of oil additives in stainless steel rolling oil
synthetic ester has crucial effect on the performance of rolling oil.Six stainless steel rolling oils were prepared by using EL(Ethyl laurate)
MH(methyl hexadecanoate)
BS(n-Butyl stearate)
DOA(Dioctyl adipate)
DOP(Dioctyl phthalate)
and TOTM(Trioctyl trimellitate)
in order to investigate the application of different esters in stainless steel rolling oils on four aspects like tribological properties
annealing properties
rolling process and surface quality after rolling.The results show: The lubricating ability of rolling oil is improving with the increase of carbon-chain length
but the increase is gradually weakened with the increase of carbon-chain length;the lubricating performance of diester and tribasic ester is better than that of the single ester;the temperature of oils volatilization is improving with the increase of carbon-chain length.Within a certain range
the surface brightness of strip after rolling has a reverse relation with the oil’s lubricant performance.
