主　　题：argon stopper technology slab casting aluminium-killed steel non-metallic inclusions 

摘      要：Argon addition into the casting channel reduces the amount of clogging on the refractory wall to allow long sequence casting of aluminium-killed steel *** key to minimum surface defects on the final product is to establish the optimum quantity by optimising the gas distribution below the stopper *** is achieved by new argon stopper technology which supports low gas quantities with homogeneous gas and bubble distributions to float non-metallic inclusions(NMI)in the continuous casting mould.
