Iron and steel production increases
  Officials and workers of the Chongjin Steel Works are increasing the production of iron and steel.
  The steel works established the raw materials preheating process using waste heat in the rotary kiln and made it possible to use in the production powder from the pellets production process and slag discarded in the past, thus normalizing the steel production on a high level while saving raw materials and fuel. It is also increasing the production while economizing on a lot of anthracite by introducing the frame thermal insulation technology based on adiabatic material into the rotary kiln.
  In particular, it built a shaft furnace of large capacity in several months to increase the production of oxidizing roasting pellets, making an epochal progress in the steel production.
  The officials and workers of the steel works are continuously pushing ahead with the iron and steel production.
