Research on Influencing Factors of EDT Automobile Aluminum Plate Surface Roughness and Control Strategy
Based on the online production data of EDT automobile plate,the influence of roll type,rolling force,rolling rate and rolling speed on the surface roughness of automobile plate are investigated.Through the analysis of the data,the setting of the optimum rolling process parameters is studied,so as to meet the requirements of customers for different roughness types.The results show that roll type is the key factor affecting the surface roughness of automobile plate.At the same time,proper rolling force and reduction amount can produce qualified products stably.There is also a certain relationship between rolling speed and surface roughness.
