It is an upward meniscus
WebThe violent upward backflow moves upward along a casting direction and tends to form unstable fluctuations in the meniscus region. Such instability and fluctuation can induce entrapment of mold powder in an internal flow and irregular growth of an initial solidified shell on the slab mold wall [ 5 ]. Web6 apr. 2024 · This metric is more valuable than looking at purely average exit velocity or max exit velocity. It takes all of a hitter’s batted balls, filters for the 10% which have been hit the hardest, and finds the average exit velocity of just that 10%. The major league average for this statistic was 103.8 mph in 2024 (minimum 55 batted ball events).
