摘要：
A method and apparatus for casting rapidly solidified metallic strip includes a nozzle mechanism which has an orifice for directing a stream of molten metal onto a movable quench surface. An upstream constraint mechanism constrains an upstream portion of a melt puddle formed on the quench surface by molten metal from the molten metal stream. A side constraint mechanism constrains two, opposite side portions of the melt puddle, and a downstream constraint mechanism provides a selected gas pressure, constraining force against a downstream, top surface of the melt puddled.
