The analysis of known methods and means of temperature and chemical composition express control in metallurgy is performed. Disadvantages of known solutions are determined. To exclude mentioned disadvantages improved technologies for express-control of cast irons and steels temperature and chemical composition are created. The methods and means of temperature measurements decrease time and cost of temperature control, as well as increase its expressity in 1.5–4.0 times. The set of thermoelectric express-analysis provides control of C, Si and Mn weight content in cast iron, during melting, with absolute error not bigger than 0.1 %. In the set for thermographic express-analysis new immersion probe device is applied. Also in this set the method of cooling thermal curves form comparison is implemented. The method is based on statistical processing of primary thermographic information.
