In 2012, Yuntie independently developed and set up China's first all-asbestos light body structure tunnel kiln for sponge iron production. This patented technology made an innovative reform of the traditional sponge iron reduction process. The patented tunnel kiln features all-asbestos insulation, a flat ceiling and uses silicon-carbide tins to feed materials to the kiln. Great heat preservation, low energy consumption and high-level automation are achieved with this patented technology. Replacing insulation bricks in the flat ceiling with asbestos reduces temperature variations on the cross section of the kiln, which enables consistent heating of both the upper and lower side of the feeding tins, thus avoiding over-heating on the top and insufficient heating at the bottom of the tins when processing sponge iron, which is often happening in the traditional kiln. This advantage builds a solid foundation for sponge iron processing in its second stage.

Consistency and reliability. In secondary reduction of sponge iron powder, Yuntie uses an electric heat treat steel belt furnace (treated with decomposed ammonia gas). Before reduction, the biconical dynamic mixer was used to mix the primary reduced sponge iron powder for consistent chemical composition and physical properties. The sponge iron cake then goes through primary crushing, secondary crushing, screening, magnetic separation and other processes before being fed to the blender in batches. Following the concepts of consistency and reliability, this crushing plant adopted continuous automatic crushing and continuous feeding process with evenly-distributed feeding mixers to retain consistent and original quality of the sponge iron powder.

Yuntie has always been improving and developing its production technologies to optimize the final products to meet our clients’ evolving needs of new iron-based raw materials. In 2014, Yuntie put the high purity sponge iron powder into mass production with 99.9% - 99.99% Fe content which features low carbon, low Sulphur, low phosphorus. This high purity sponge iron powder has established the properties of great electro-conductivity and magneto-conductivity which can serve great alternative solutions for various industries.
