The Munphyong Smeltery is increasing the output.
The smeltery set a higher goal for technical upgrading on the basis of the successes and experience gained in last year's readjustment and reinforcement of equipment, and is now carrying on it.
It is fulfilling its monthly and quarterly plans for producing lead and zinc by revitalizing the operation of the upgraded calcination-sulphuric acid production line and managing equipment and improving technical control according to the processes. And it is also pressing ahead with the strengthening of its material and technical foundations.
The workers in charge of the production of lead pushed ahead with the improvement of the performance of electric furnaces with their own efforts and technology to increase the lead output per unit 1.3 times as against last year.
Officials and workers in the field of zinc production also established the line of producing zinc oxide by a revolving furnace and boosted the electrolytic zinc output over two times more than before.
The smeltery updated the computer control system for production lines and took technical measures to increase crude lead production by the electric furnace. It also opened up a prospect of using locally available raw and other materials and recycling waste materials. It is stepping up the installation of the dust collection process to improve the working conditions and environment.
