A number of technical innovators and master-hands at contrivance is increasing among the young people in the fields of the key industries.

The shock brigade members for technical innovation of the Hwanghae Iron and Steel Complex completed the method of manufacturing insulating bricks from waste materials and the production of a pillow block for the rolling mill.

Young people of the Hungnam Fertilizer Complex and February 8 Vinalon Complex studied and introduced the technical innovations for remarkably raising the retrieval rate of hydrogen in gas-separation process, updated a waste gas absorber in the process of enriching sulfuric acid, and thus contributed to the current production and environment protection.

Those in electricity and coal production units made new valuable technical innovations to ease electricity strain and satisfy the increasing demand for coal.

Those in the light industrial sector are playing a pivotal role in the work for modernizing equipment, ensuring domestic production of raw materials and recycling, developing new goods and raising their quality.
