The work is a part of research into the reduction of energy consumption in the production of EPSthrough the modernization
of technological equipment used. This paper presents the results of research and analysis of heat transfer process between the water vapor
that was provided to machine, the mold, the product and the environment. The paper shows the calculation of the heat balance of the
production cycle for two types of mold: standard and modernized. The performance tests used an infrared imaging camera.
The results were used to develop a computer image analysis and statistical analysis. This paper presents the main stages of the production
process and the construction of technological equipment used, changing the mold surface temperature field during the production cycle
and the structure of the heat balance for the mold and its instrumentation. It has been shown that the modernization of construction
of technological equipment has reduced the temperature field and as a consequence of decreased of demand for process steam production
cycle.
The paper presents the results of studies on the development of manufacturing technologies to cast hearth plates operating in chamber
furnaces for heat treatment. Castings made from the heat-resistant G-X40CrNiSi27-4 steel were poured in hand-made green sand molds.
The following operations were performed: computer simulation to predict the distribution of internal defects in castings produced by the
above mentioned technology with risers bare and coated with exothermic and insulating sleeves, analysis of each variant of the technology,
and manufacture of experimental castings. As a result of the conducted studies and analysis it was found that the use of risers with
exothermic sleeves does not affect to a significant degree the quality of the produced castings of hearth plates, but it significantly improves
the metal yield.
