METHOD OF EMULSION CONCENTRATION OPTIMIZATION FOR COLD CONTINUOUS ROLLING MILL SET

摘要

Disclosed is a method of emulsion concentration optimization for a cold continuous rolling mill set for the purpose of vibration suppression, the method comprising: defining the process parameters involved in the process of emulsion concentration optimization; providing an initial set value of an emulsion concentration comprehensive optimization target function for a cold continuous rolling mill set for the purpose of vibration suppression; calculating a gripping angle of each stand; calculating a vibration determination index reference value of each stand; setting the emulsion concentration of each stand; calculating the temperature of a strip steel outlet of each stand; calculating the dynamic viscosity of an emulsion in a roll gap of each stand; calculating the thickness of an oil film in the roll gap of each stand; calculating the emulsion concentration comprehensive optimization target function; determining whether the inequation F(X) F ₀ is established; and determining whether the concentration of the emulsion exceeds a feasible region range, and outputting the optimal emulsion concentration set value.
