Its officials, technicians and workers introduced hundreds of valuable technical innovations this year to make a breakthrough in the modernization of production lines and revitalization of production.

The Blast Furnace Workshop No. 1 applied an innovation to give precedence to the heating up of the steel ladle, and thus increased the combustion efficiency. As a result, the actual extraction rate was raised.

The technicians and workers at the Blast Furnace Workshop No. 2 increased the productivity of Juche iron by solving the technical problem arising in supplying enough oxygen to the systems.

Similar successes have been made by fireproof material producing unit, hot-rolling shop, gas-producing shop, steel ingot shop and other units.
