内容简介

Long time casting under low gas flow was achieved by using material having uniform pore size distribution and stable high temperature structure. Gas leakage was suppressed by using an improved gas blowing system in which gas blowing was done separately in the upper and lower part. From the above improvements, nozzle clogging in the upper nozzle was effectively prevented and very good results were obtained in field tests. Further study on the prevention of nozzle clogging is expected to continue in the future.
