Scientists of the Nano-engineering Branch of the State Academy of Sciences developed a Korean-style technology of producing biological binder for metallurgy.

Biological binder is produced in the process of pyrolyzing such biomass as rice chaff and sawdust at a certain temperature and at a fast speed.

The Nano-engineering Branch established the technology for fast pyrolysis of biomass, the core of research into binder, in a Korean way and found out all the industrial indices.

The research results were introduced on a trial basis into the production of refractories at the Kim Chaek Iron and Steel Complex.

As a result, the life of the steel ladle increased and the heating time shortened remarkably as compared to when the refractory made with imported binder was used.

The complex set up a process capable of annually producing well over a hundred tons of refractories using the biological binder and gave it a trial run in early October.

According to an official concerned, the establishment of the technology of producing and using the biological binder for metallurgy with locally abundant biomass as raw material has made it possible to further perfect the Korean-style iron production system and reduce the costs of iron and steel production.

Scientists of the branch are now working to widely introduce the technology into different economic sectors.
