Abstract

An experiment of continuous casting with ultra-high frequency electromagnetic field was carried out at No. 4 commercial caster at Kobe Works. It was confirmed that the durability of a slit mould was sufficient for long casting, and meniscus level was controlled precisely enough for stable casting by the level control technology using the inductance change in the magnetic system. The improvement of billet surface quality and the lubrication between the mould and the solidified shell are discussed.
