For the purpose of achieving further development of the horizontal continuous casting process established in the manufacture of small and medium section billets of carbon steel, the authors have developed techniques for horizontal continuous casting of stainless steel and high alloy steel grades and large-section billets. For the application of high-cycle intermittent withdrawal indispensable in horizontal continuous casting to very heavy cast strands of large-section billets, innovations have been made in equipment and control techniques of withdrawal. Casting of stainless steel and high alloy steel grades is now practicable through optimization of the mold conicity and use of break ring made of a new material. For further improvement of HCC billet quality, on the other hand, Hot Shot Blast to eliminate cold shut cracks on the billet surface and a new implementation of EMS to improve the billet center quality have been developed. These efforts are bringing about excellent results in application tests of HCC billets to such various products as rolled wires and rods, and seamless tubes and pipes.
