This paper considers the problem of developing a model of thermal metal processing by
multiprocessor computing systems. The obtained metal is used for high-strength
fasteners manufactured by cold forging method without final heat treatment. The model
is based on the heat treatment method of a billet from low- and medium-carbon steels
intended for cold heading. The model aims at improving technological properties of a
billet by ensuring high dispersion and uniformity of a billet structure across the entire
plane of its cross-section.
Implementation of the proposed model ensures the technical result of high dispersion
and uniformity of the structure of the billet. The technological process of steel heat
treatment is characterized by high performance, low power consumption, and improved
performance characteristics. The apparatus for implementation of the spheroidization
annealing regime determines the uniform distribution of cementite globules in the ferrite
matrix, which means that it provides the necessary mechanical properties of the metal
for its further cold deformation. The multiprocessor computing system software allows
controlling the temperature conditions, both on the entire plane of the billet section, and
across its length. Such temperature conditions are controlled in the center of the plane of
the billet cross-section.
Experimental studies of the heat treatment of metal products were conducted. In order to
test the functions of the proposed model, several experiments were performed when a
20 mm diameter wire from 20G2G steel was subjected to heat treatment. Experimental
studies have shown that metal has the necessary elasticity properties, saving the
required hardness
