The Chollima Steel Complex increases the quality and quantity of iron and steel by introducing new technologies.
It has introduced an electromagnetic induction and agitation technology into the continuous ingot moulder.
A few years ago alone, it failed to produce various grades of steel that are needed in different economic sectors, including the production of truck and tractor, as it could not ensure the qualitative indices to be attained in the continuous casting process. That is why it introduced this technology.
The complex solved various scientific and technological problems arising in designing and manufacturing the inductor, the core of the agitation technology, including the matter of the inductor coil that can stand high electric current and high-temperature water, thereby establishing the electromagnetic induction and agitation process.
The application of this technology has made it possible to increase the actual output of iron and steel products, remarkably improve steel quality and produce alloys with various steel grades needed at machine factories, like steel for bearing and wire.
The complex also introduced the slag-alkali cement, which was developed by the silicate engineering institute of the State Academy of Sciences, into the lining of the heating furnace for the 6 000-ton press forging.
The slag-alkali cement is a heat-resistant concrete compound which can replace alumina cement, a typical heat-resistant cement used in the lining of such thermal equipment as boiler and cement kiln cooler.
The researchers developed the slag-alkali cement that is highly resistant to heat in the course of research into the effective use of slag, the waste from blast furnaces at ferrous metal factories.
The forging furnace at the Chollima Steel Complex is the first industrial furnace of metal factory in the country that has introduced the technology of producing heat-resistant concrete with slag-alkali cement.
