This paper summarizes the reports of latest developments on industrial application of continuous casting technology in high speed steel production abroad. In addition

and summarizes some Chinese enterprises and research institutions have done some research and industrial trial production in this field. It is suggested to increase investment on the research and development of continuous casting technology of high carbon and high alloy steel grades. Compared with the traditional casting

the research shows that continuous casting can reduce the thickness of coarse carbide by 40% and the grain size by 50%

and the carbide pattern is also changed from flat and lamellar to fibrous

which will facilitate the carbide refinement in the subsequent forging and rolling process.Finally

it is proposed that the continuous caster straightening machine

water cooling process

billet cross-section size and finished forging ratio can be optimized. If a breakthrough can be male in current technology of mature arc continous casting machine

it will be condueive to improve the quality of casting billet

and achieue industrial application of high carbon and high alloy die steel casting.
