Technical requirements for hydrogen-rich systems in blast furnace smelting of hydrogen metallurgy

1 Scope

GB/T 47039-2026 is the Chinese national standard covering injecting hydrogen into a blast furnace - replacing part of the coke's reducing work with a gas whose product is water rather than CO2, with the injection system, the effect on the furnace's thermal and chemical balance and the safety of hydrogen at a tuyere. It is the transitional step for an industry that cannot rebuild every furnace at once. First edition, in force since 1 May 2026. It was issued on 28 January 2026 and has been in force since 1 May 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the principles and technological process, general provisions, equipment and operating system of the hydrogen-rich blast furnace smelting system, and outlines its operation. Management and maintenance requirements. This document applies to the design, operation, management, and maintenance of hydrogen-rich systems for newly built, renovated, or expanded blast furnace smelting in the steel industry.
