"Krasny Kotelshchik" tested new equipment
"The Taganrog Boiler-Making Works "Krasny Kotelshchik" (TKZ) has introduced into production a plant for heat treatment (austenization) of heat-exchange tubes. Due to this decision, it was possible to abandon the purchase of heat-treated purchase items, significantly reducing the company's costs.
This plant is designed for cold worked austenitic steel pipes. The diameter of such workpieces can be from 16 to 25 mm, the wall thickness from 0.8 to 1 mm. Tubes are heated directly at the bending points using direct current, after which they are transferred along the technological chain of manufacturing heat exchangers as part of the implementation of "nuclear" projects.
The new plant has advanced features. In particular, for the time interval specified by the operator it is capable of heating the bend in the temperature range from 1030 to 1050 ° C. The required heat treatment modes are selected in accordance with the specified program. The austenitizing chart is shown on a special display. The results of heat treatment are recorded on a flash drive with further storage of archived data.
