Abstract

The results of preliminary thermal cycling deformation and subsequent annealing in the range of

100-900 °C in steps of 100 °C on the structure and electrical resistivity low carbon steel sheet

Ст3пс. The possibility of reducing the electrical resistivity of more than 3% through the use of pre-

rational modes of thermal cycling rolling. Found that use thermocycling further deformation

(rolling cycles 5), with a high degree of compression cycles (20-50 %) to obtain a thin sheet having

a thickness of 1 mm to increase the specific electrical resistance is proportional to the degree of

deformation. Overall reduction of electrical resistivity of the hot-rolled steel by using Ст3пс DTCT

mode and subsequent annealing at 700 ° C for 1 hour on average 6-8 %.
