The complexity of using instruments for measuring the technological parameters of induction melting in a continuous mode,
and sometimes the impossibility of this, requires the creation of reliable indirect methods for assessing the numerical values of these
parameters. This is especially important for quality control of control systems that ensure a given melting temperature regime. The
paper proposes a classification rule based on parametric classification methods, which makes it possible to determine the tempera

Checking the classifying ability of the obtained rule showed that it is high, since for all the numerical data of the factor-signs,
both the high-temperature and low-temperature modes were classified correctly. The restrictions on the application of the classification
rule are shown, among them: the restrictions imposed by the range of variation of the values of the attribute factors, and the restrictions
imposed by the small sample of the initial data, as well as the arbitrary area of their distribution in the space of the factor-attributes.
The rule is presented in a normalized form, and also converted to natural form for ease of practical use.
Application of the rule can be recommended to technologists of metallurgical production of foundries to check the com
