METHOD OF PRODUCING CONTINUOUSLY-CAST STEEL BILLETS Russian patent published in 2011 - IPC B22D11/10 

FIELD: process engineering.

SUBSTANCE: invention relates to metallurgy. Proposed method comprises metal casting into crystalliser, shaping the billet by squeezing and gauging its surface, and continuous pushing the billet out. Squeezing and gauging is performed with the help of crystalliser with its two walls reciprocating and two inclined walls revolving. Control over metal level in crystalliser is performed with the help of SHF electromagnetic waves emitted by generator. Signal is recorded by oscilloscope and processed by ACS. Billet shaping is started ay crystalliser metal level of H₁=(0.25-0.35)H, where H is the height of widened section of top inclined walls.

EFFECT: higher reliability and efficiency of metal level control.
