On the Issue of Recrystallization Annealing of Dynamo Steel

The effect of preliminary high-speed heating before recrystallization annealing of dynamite steel has been studied. The change in microstructure during annealing at different temperatures and holding times has been studied. A comparison was made with the parameters of steel obtained using the traditional method of heat treatment. Based on the obtained experimental data, conclusions were drawn about the influence of preliminary high-speed heating, temperature and holding time of recrystallization annealing on the kinetics of recrystallization and about the possibility of using new heat treatment technologies to intensify production and obtain steel with better characteristics.
