Scherbak O. Slag castings foundation blocks of siliconmanganese slag

The object of study: the processes of production slag molding foundation blocks. The purpose and objectives of the study. The aim of the thesis is the development of theoretical propositions concerning slag molding products and production technology development foundation blocks slag molding silicomanganese slag. The objective of the thesis led to the need to address the following problems: to conduct theoretical and experimental research on the justification for the use of molten slag of silicomanganese slag molding for foundation blocks; to determine the temperatures of formation of slag molding base blocks; research phase mineralogical composition and basic physical and mechanical properties of slag molding foundation blocks silicomanganese slag; develop and implement the production technology of slag molding foundation blocks silicomanganese slag and calculate the anticipated economic efficiency. Subject of research: fundamental blocks of slag molding vohneridkyh silicomanganese slag. Research methods. The paper used theoretical and experimental methods based on known scientific provisions specifying properties of composite materials, which include slag molding products. Determination of inputs and tumors conducted on the basis of chemical and X-ray diffraction, differential thermal (DT), electron microscopic analysis methods using DRON-4 system derivatohrafa RD A., F. and N. Paulik Paulik. Physical and mechanical properties of the materials studied by standard methods, in accordance with current regulations. Scientific novelty of the results: established theoretical and experimental studies that phase transformations during cooling and crystallization vohneridkoho slag of silicomanganese largely correspond to equilibrium crystallization on the chart system CaO - MgO - SiO2, than the chart system CaO - MnO - SiO2, although the content of MnO in the slag is significantly higher than the content MgO; proved that cooling vohneridkoho slag of silicomanganese interval 1050 - 900 ° C corresponding to the interval highlight major crystalline phases: alabandinu and minerals of clinopyroxene, such as diopside Mg (Si2O6).Degree of implementation: introduced in 2013 - 2014 years in production (in terms of "Techno SKARM") slag molding manufacturing technology foundation blocks silicomanganese slag allowed to obtain economic benefit in their manufacture in volume 2300 m3 - 218 thousand.
