On March 1, 2011, Nanjing Allied Rongda signed with Quzhou Yuanli on wet spraying for blast furnace lining and started operating on lining repair project. This project adopted a new self-developed technology of blast furnace lining shotcrete, which has been implemented in six blast furnace lining repair project domestic and abroad.
This construction materials weighed 115 tons, and it took less than sixteen hours from cleaning to shotcrete end of furnace inner. Equipment was operated continuously and stably. After shotcrete the materials were bonded strong with a smooth surface, without phenomenon of shedding and broken mark after blow-in, which has been highly valued among customers. Decided to continue to make another blast furnace lining repaired by Allied Rongda’s shotcrete.
