Abstract:SCR9000 copper rod production line is introduced by Guangzhou JCC Copper Products Co.， Ltd. from Southwire Company in 2019. The diameter of the casting wheel is 3660 mm and the weight is 4.5 t. After the casting wheel is used for a period of time， it is necessary to sand blast the surface of copper ring off the line to clean the impurities， form a specific roughness and improve the surface strength. Traditional sand blasting of casting wheel generally adopts ordinary yellow sand， and manual sand blasting has a bad working environment. Through independent design and research， an automatic casting wheel sand blasting machine suitable for SCR 9000 copper rod production line has been developed.
