Process for producing die steel by utilizing converter continuous casting mode

The invention discloses a process for producing die steel by utilizing a converter continuous casting mode. The process comprises a steel making continuous casting process and a steel rolling process. The steel making continuous casting process comprises the following process steps of: converter smelting, LF (Ladle Furnace) refining, continuous casting, slow cooling and other process steps; and the steel rolling process comprises the following process steps of: heating, scale removal by using high pressure water, rolling, straightening, stacking, slow cooling and other steps. By using the die steel produced by the invention, the contents of gas and occluded foreign substances in the die steel can be reduced, the thermal stress and the structural stress for slowing a steel blank down are eliminated, a thick and nonuniform cast structure inside the steel blank is improved, and the problems of flaw detection disqualification and finished product crack of the die steel are solved. By using the process, the aim of producing the die steel by using a converter is achieved, the production cost is reduced, and the economic benefit is increased.
