This article analyzes that the creation of mathematical models of chemical-technological
processes during the development of various alloys is supported to obtain promising new alloys in the
foundry industry. Mathematical models have been developed and analytically implemented using linear
algebra methods. Numerical values were determined and graphs of changes in the required parameters
were constructed. The development and analytical implementation of a mathematical model of the process
makes it possible to simplify practical research, and it is possible to predict the results of subsequent
experiments. This serves as the basis for the automation of chemical technological processes in the
production of non-ferrous metals and alloysΠ ΡΡΠ°ΡΡΠ΅ ΠΏΡΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡΠΎΠ²Π°Π½ΠΎ, ΡΡΠΎ ΡΠΎΠ·Π΄Π°Π½ΠΈΠ΅ ΠΌΠ°ΡΠ΅ΠΌΠ°ΡΠΈΡΠ΅ΡΠΊΠΈΡ

The efficient operation of the technological equipment of machinery manufacturing enterprises
and heavy industry without distortion depends in many respects on the strength of their details. This
requires the study of the process of operation of the details, which are mainly rubbed with each other.
These methods are widely used in obtaining high-quality steel castings. The simplest method of processing
steel outside the oven is modification. Modified carbon steel is much more economical in properties
approaches to leached steel, while modified steel leached by saving and investigation approaches
leached steel with valuable and rare additives (Ni, Mo, Ti and other). Modification with alkaline and
alkaline-earth metals greatly increases the quality of steel. The quality of steel is positively influenced
by nitride-forming modifiersΠΡΡΠ΅ΠΊΡΠΈΠ²Π½Π°Ρ ΡΠ°Π±ΠΎΡΠ° ΡΠ΅Ρ

This paper examines the effect of heater power, speed of drying agent (air), adjustable slit
width and number of revolutions of drying drum on the drying efficiency of the device, the moisture
content of the rice pile coming out of the drum, and the chatness of rice in the rice pile. In addition,
showed the changes in the value of the heating power and the drying efficiency of the device. The
change of the adjustable slot size of the drying drum and the drying efficiency of the device consist
of determining the effect of the moisture content of the pile of rice coming out of the drum and the
effect of rice chatnash in the pile of rice. The experimental rice drying device in a stationary version
was prepared at the βAndijan experimental- testing plantβ JSC according to the design drawings developed by the Andijan Institute of Mechanical Engineering. Based on the results of theoretical
studies, a drying drum with a diameter of 880 mm and a length of 1800 mm was adopted as the main
