AP19576811 «Development of a Technology for Obtaining a Marketable Product from Fine Dust of Ferroalloy Production» – Scientific Supervisor- D.A. Isagulova
Relevance
Ferroalloy production generates a significant amount of by-products, such as slag, residues of fine fractions of raw ore materials and finished products (ferroalloys), sludge, dust, and various other materials. The use and processing of these materials can reduce the consumption of primary natural resources, thereby increasing the efficiency of the main production process and reducing environmental pollution.
The greatest environmental risks are posed by technogenic wastes from the metallurgical sector of ferroalloy production, which primarily consist of fine-dispersed materials in the form of dust and sludge from various stages of manufacturing.
One of the main methods for enlarging powdery substances is briquetting—a process that requires energy only to shape and compact the briquettes, without the need for thermal energy for agglomeration. Briquetting is the most cost-effective and compact method of pelletizing various dusty materials. Therefore, briquetting production waste using presses becomes economically feasible.
The goal of the project is to develop a new technology for producing ferrosilicon briquettes from fine dust generated in ferroalloy production using a new complex binder material.
Expected and Achieved Results
As a result of the project implementation, the following outcomes are expected:
A new composition of briquetted ferrosilicon will be obtained;
A new technology for producing strong briquettes from dust will be developed;
The interaction mechanism between fine ferroalloy production dust and the new complex binder material will be determined.
Achieved results to date:
As a result of the literature review on the issue under study, the objectives and tasks of the research have been formulated.
Initial samples of a marketable product from fine dust (FD) have been obtained. A series of further studies is planned to examine the complete compositional characteristics and chemical properties of the resulting product.
This work is a preliminary study aimed at determining the optimal parameters. Two different binders and two different compositions were tested.
The study shows that this process can be extended to the reuse of other loose solid wastes from ferroalloy production and offers a comprehensive solution for the recycling of bulk solid wastes.
Achieved Results
For the year 2023 – Work was carried out to assess the feasibility of developing the ferroalloy industry in the Republic of Kazakhstan through the production of marketable products from ferroalloy dust.
Key global trends in the development of the ferroalloy industry were identified. Data on binder compositions and their chemical properties were collected.
Ferrosilicon (FeSi) is used in the steel industry as a modifier added during smelting, as a deoxidizer, and as a melting agent in the production of steel and cast iron.
Information analysis shows that a significant amount of waste is generated during ferroalloy production, including fine ferroalloy dust and other materials. Their utilization and processing can reduce the consumption of primary raw materials, increase production efficiency, and lower environmental pollution.
However, the scale of waste recycling in ferroalloy production remains relatively low. The recycling and reuse of waste as secondary resources are currently relevant and necessary.
The conducted information analysis showed that methods of waste utilization during ferroalloy smelting at production sites are still insufficiently explored. Briquetting is a promising method for secondary processing. Briquettes introduced into furnaces must have certain mechanical and chemical properties. However, there is no standard for determining the suitability of briquettes used in smelting, and no optimal binder has yet been established for waste use.
Thus, by experimenting with different binders, it is possible to find an effective method for briquetting ferroalloy production waste, including fine dust, to obtain strong briquettes and improve the assimilation of alloying elements during their subsequent use.
Work was carried out to produce sample dust-based briquettes from ferrosilicon with a grain size of 0–3 mm using liquid glass as a binder. Ferrosilicon production is an energy-intensive process requiring significant amounts of electricity and raw materials such as ore, quartz (quartzite), fluxes, and reducing agents like coke, coal, and biomass.
The process also generates residues such as filter dust (silica fume), scrubber sludge, and slag. A convenient and cost-effective way of using ferrosilicon dust is briquetting and granulation. High pressing forces result in strong, non-crumbling briquettes.

One article was published in a journal indexed in the Scopus database with a CiteScore percentile of 35.
One patent for a utility model was obtained in the Republic of Kazakhstan.
For the year 2024 – Research was carried out on the use of various components as binders.
One of the key aspects in the briquetting of fine ferroalloy production dust (FAPD) is the correct selection of the binder component. The binder must provide sufficient plasticity for briquette formation, ensure mechanical strength after appropriate treatment (e.g., drying), and not significantly alter the chemical composition of the briquette so that it complies with the relevant GOST standard for the specific ferroalloy.
A significant amount of research has been devoted to identifying a suitable binder and developing a briquetting charge composition based on FAPD. The optimal binder composition was selected based on the mechanical and chemical properties of the resulting briquettes. The optimal formulation of the final product was determined.
A complex binder composed of liquid glass and bentonite clay was proposed. Various ratios of these additives were studied. The probable strengthening mechanism involves the encapsulation (coating) of dispersed dust particles with clay and their strong adhesive bonding in a liquid glass medium.
Experimental smelting was carried out at the production sites of LLP “NPO Manganets” and LLP “KMZ named after Parkhomenko”, where steel was smelted using test briquettes produced using the developed technology.
A preliminary process flow chart was developed — laboratory tests were conducted to assess the effect of composition and structure of briquettes made from fine ferroalloy production dust.
One article was published in a journal indexed in the KOKSON database.
One article was published in a journal indexed in the Scopus database with a CiteScore percentile of 35.
One utility model patent was obtained in the Republic of Kazakhstan.
For the year 2025 – Laboratory studies were conducted to examine the influence of briquetting parameters on the properties of briquettes made from fine dust (FAPD) generated in ferroalloy production, using iron ore concentrate as part of the charge. The composition of the resulting briquettes corresponds to that of ferrosilicon grade FS50, which makes it possible to use these briquettes as a substitute for standard FS50.
Experimental melts were carried out at the production facilities of the branch of the NC KPM “Z. Abishev Institute of Chemistry and Metallurgy” and LLP “KMZ named after Parkhomenko,” where steel was smelted with partial use of experimental briquettes obtained using the developed technology.
The briquettes were produced from high-dispersion dust (HDD) from ferrosilicon production with the addition of iron ore concentrate. The chemical composition, mechanical properties, and microstructure of the resulting metal were studied.
An act of industrial tests was obtained.

AP19578884: Improving Wear Resistance and Enhancing the Design of Busbar Punching Tool Scientific Supervisor- Mussayev M.M.
Relevance
The global integration of domestic and foreign manufacturers has led to an increased use of foreign equipment in the domestic industry. One such example is busbar punching machines.
The manufacturers and suppliers of these machines, as well as the associated technological and tooling equipment, are primarily Russian and Chinese companies. It has been identified that the tools used for punching holes in busbars wear out quickly and fail more frequently. Worn tools are replaced with new ones, which are purchased from foreign manufacturers. The high consumption of tools significantly increases production costs.
Research results confirmed that the tools used for punching holes in busbars wear out quickly and are prone to frequent failure. Worn tools are replaced with new ones sourced from foreign manufacturers, and the high tool consumption negatively affects the cost of the produced products.
This situation highlights the need to develop a technology to enhance the wear resistance of busbar punching tool designs. Scientific research aimed at solving this problem is therefore highly relevant.
Project Objective
The objective of the project is to increase the wear resistance and improve the design of the busbar punching tool.
Achieved Results
As a result of the project, a technology for increasing the wear resistance of the working part of the busbar punching tool has been developed. A prototype of the busbar punching tool was designed and manufactured. The project led to new scientific and technical solutions, which include:
– Development of a technology to ensure the wear resistance of the busbar punching tool design, including the establishment of patterns of the interrelated influence of punching modes, geometric parameters, and tool material on its wear resistance; enhancement of the wear resistance of working surfaces using technological methods and heat treatment; determination of optimal punching modes and tool geometry depending on the material being processed.
– Creation of a mathematical model for assessing the wear resistance of the tool surface.
– Development of a combined (modular and monolithic) design of the busbar punching tool.
– Development of a methodology for calculating the stress-strain and thermal state of the tool design during processing using specialized computer programs.
The developed busbar punching tool represents an improved design, implemented in either modular or monolithic form. Implementation of the developed design allowed for an increase in tool wear resistance by 25–40% compared to existing analogs, extended its service life by 1.5–2 times, and reduced costs for repair and replacement of worn elements by 20–30%. The economic effect is achieved through reduced equipment downtime, increased productivity, and decreased unit costs of busbar punching operations.

Relevance
Due to the desire to continually improve performance and efficiency, minimize dimensions, and reduce vibration, pulsation, adverse loads, cavitation, and wear of gear pump components, the requirements for materials, technologies, fits, and dimensional tolerances are constantly increasing. This leads to continuous improvements in manufacturing methods, both for the pumps themselves and the materials used for their construction. The most important indicators are the lowest possible failure rate, a wide range of applicability in a given industry, resistance to changing conditions, and the lowest possible noise and pulsation.
Thus, the concept of an innovative gear pump for hydraulic control systems of industrial machines using various types of oils, as well as a compact design solution for damping mechanical vibrations and reducing power loads, was developed.
Project Goal

An analysis of the obtained experimental data shows that the proposed multi-gear pump design is feasible. Best performance can be achieved at a rotation speed of n = 900–1450 rpm, as lower speeds reduce pump performance and increase fluid leakage. Operating pressure reaches 25 MPa.
