Process Innovation

Tsingshan persists in drawing nourishment from "dare to be the first, innovative reform" principle. Over many years, Tsingshan has never stopped making innovations in the fields of process, technology and management, etc. Therefore, it has obtained many patents for technological innovations, many of which have had a significant impact on the progress of the industry.

It is Tsingshan that pioneered the world's first RKEF-AOD full-heating-delivery integrated stainless steel production line, which not only reduced energy consumption, but also reduced the environmental impact of various types of emissions, changed the traditional mode of stainless-steel production, and realized the integration of nickel-iron and stainless-steel. The historic breakthrough in production has set a benchmark for the world's stainless-steel smelting energy-saving emission reduction. . It has created a new era of stainless-steel production in the world and is a major innovation and milestone in the history of stainless-steel development in the world.

The subsidiaries of Tsingshan have obtained hundreds of utility and innovation patents, such as the movable AOD furnace, RKEF+AOD and other products, which have had a huge influence on the industry. 

Tsingshan has applied for the national practical patent with its self-innovation argon oxygen decarburization refining device. This device has simplified the stainless steel smelting procedures to play a part in energy saving, product quality and production efficiency and cost reduction. 

The horizontal continuous casting tundish heating device is also honored with national practical patent because it can not only produce steel with steel liquid under low temperature, but also cast the steel under constant low temperature.

To innovate its products and technology, Tsingshan has founded the technologically advanced R&D Center and a well-equipped research institute. Considering that it passes through national CNAS and other authentications, it has made remarkable achievements in its consistent production process and new product development. 

By now, Tsingshan has succeeded in super duplex stainless steel,Precipitation- hardening stainless-steel, 400 series stainless-steel, free-cutting stainless-steel, heat-resistance stainless steel, valve steel, die steel and other products.
