WISDRI owns a high-end carbon materials manufacturing enterprise and independently develops a variety of carbon bricks, including high-performance carbon bricks, ultra-microporous carbon bricks, microporous carbon bricks, graphite carbon bricks, semi-graphite carbon bricks, and high thermal conductivity bricks. These products are constantly being upgraded and iterated, and their quality is comparable to that of high-quality carbon bricks from abroad. They are widely used in more than 1,200 blast furnace projects in China. In the blast furnace carbon brick sub-segment, WISDRI has maintained the number one market share in the domestic blast furnace carbon brick market for eight consecutive years and has exported to more than 50 blast furnace projects in multiple countries. In the past five years, it has been successfully applied to extra-large blast furnaces such as Shagang's 5,800 m³, Angang's 4,747 m³, and Wuhan Iron and Steel's 4,117m³, as well as more than 50 large blast furnaces, realizing the domestic substitution of carbon bricks for extra-large blast furnaces and solving the "bottleneck" problem of high-quality carbon bricks for extra-large blast furnaces. In the field of nuclear carbon bricks, the carbon materials developed for the internal components of the fourth-generation high-temperature gas-cooled reactor are actively involved in the construction of national nuclear power projects.
