Due to the characteristics of the HHHHHHHHH smelting reduction technology, the molten iron produced by the process has higher purity, particularly the content of P element is lower than that of other iron making processes, the content of other elements such as V, Ti, Si, Sn, SH, TH, Bi and Pb is lower, and the content of S element is slightly higher than that of other processes, but the molten iron de-S is a very mature process, so that the process is very suitable for producing high-purity pig iron for high-end castings such as nuclear power, wind power, aviation, aerospace and the like.

The high-end casting is produced by adopting a continuous casting mode of an iron casting machine for producing the high-purity pig iron, the running speed of the iron casting machine needs to be reasonably matched with the casting speed, otherwise the cast pig iron has different shapes or pig iron blocks cannot be separated due to excessive connection of molten iron, and the process requirements are difficult to meet. Before pig iron casting, molten iron in a furnace needs to be transported to a pouring area by a ladle, and the molten iron is poured into an iron casting machine by tipping the molten iron.
