METHOD FOR PRODUCTION OF SUPER PURE ALUMINUM DEOXIDISED FOR PRODUCTION OF HIGH-QUALITY METAL PRODUCTS Russian patent published in 2021 - IPC C21C5/28 C21C5/52 C21C7/00 B22D11/00 

FIELD: ferrous metallurgy.

SUBSTANCE: invention relates to production of super pure aluminum deoxidized for production of high-quality metal products, which involves monitoring of all stages of production from the outlet of the liquid semi-product from the steelmaking unit, out-of-furnace treatment to steel casting and crystallisation of the ingot in the crystallizer of the continuous steel casting plant (CSCP).

EFFECT: invention enables to obtain a highly pure steel with low content of oxide and sulphide non-metallic inclusions with size of less than 20 mcm, taking into account the chemical composition of all materials and media, in contact with liquid metal in steel-pouring and intermediate teeming ladles, and also to ensure stable and sufficiently high output of suitable products without surface and internal steel-smelting defects in metal rolling.
