Know–how in the steel industry

One of the secrets of Russian scientists is the use of rice processing waste.

"We have created a world-class technology package that allows us to start domestic production of high-quality steel products - alloyed, stainless, heat-resistant, corrosion-resistant, electrical and other steels, which will significantly increase the competitiveness of machine-building, automotive, and oil and gas enterprises."

This is how N.A. Abykaev, head of the work "Development of world-class technologies for involving low-quality (high-phosphorous lignite) and man-made raw materials in the processing of low-quality (high-phosphorous lignite) and man-made raw materials that increase the competitiveness of steel production, and their commercialization," described the new development of Kazakhstani scientists, which was nominated for the State Prize of the Republic of Kazakhstan in the field of Science and technology named after Al- Farabi 2017. The work of a team of scientists was presented in Almaty during a round table dedicated to the topic "Raw materials for the machine-building industry of Kazakhstan." It was held by the Ministry of Investment and Development, the Kazakhstan National Academy of Natural Sciences, the National Chamber of Entrepreneurs "Atameken", the Union of Machine Builders of Kazakhstan, the National Center for Integrated Processing of Mineral Raw Materials of the Republic of Kazakhstan. The submitted work was pre-selected and discussed during the round table.

As noted during the meeting, unique author's developments have been successfully tested and implemented at various enterprises in Kazakhstan and Russia.

They ensure the production of competitive steel products for mechanical engineering at all stages of metallurgical production: from the expansion of the raw material base to the smelting of high-quality steels with significant economic, environmental and social effects. The cost of producing 1 ton of steel has been reduced by $10. High-quality iron concentrate was obtained from practically unclaimed local raw materials. At cost, it is 38% lower than the concentrate currently used in the production process.

For the first time, special-purpose steel of the X80 strength category was smelted and rolled at a domestic plant. Kazakhstan's demand for sheet metal of this steel is high, as it is used for the manufacture of oil and gas pipes and is necessary to ensure the operation of the Aktau Pipe Plant at full capacity.The scientists of the Academy and the center have provided the opportunity to produce competitive electrotechnical steels thanks to the development of a unique technology for producing ferrosilicon with a low aluminum content from non–metallic raw materials – rice processing waste - with production costs 250 dollars lower than analogues. The issue of replacing scarce pig iron and steel scrap in steelmaking with ferrous waste from metallurgical industries has been resolved. The replacement of up to 10% of scrap metal, as shown by tests at KSP Steel LLP and Casting LLP, reduces the cost of smelting 1 ton of steel to $ 18.

In order to increase the productivity and reliability of the main metallurgical units, new refractory materials have been created. The effectiveness of their use was demonstrated by positive test results at Kazakhmys Corporation LLP. The introduction of refractories in Kazzink LLP allowed to increase the annual output of rough copper by 2,715.6 tons and ensure annual economic efficiency up to 55.6 million tenge. Currently, various types of refractory materials with a total volume of 2,500 tons worth up to 1.5 billion tenge have been adopted for permanent use at AMT.

The participants of the round table noted the high importance of the work under discussion and the outstanding achievements of the author's team, worthy of the highest recognition before society and the state.
