Vlasov А. F., Bogutskiy А. А. — Electroslag remelting on firm start according to the monofilyarny scheme of the process conducting with use of exothermic conducting flux

Experimental methods established that developed method using a solid start with ekzotermicheskih fluxes of conducting an electric current in the solid state, significantly reduces the time needed to slag bath required amount. Granulometric composition of exothermic flux noticeable effect on the macrostructure of the steel does not have practically no effect on the chemical composition of metal the height of the ingot. The proposed method using ESR start ekzotermicheskih flux has no negative effect on the quality of the bottom of the ingot. The technological process of accelerated guidance slag bath solid start at monofilyarnoy diagram of the process.

RECEIPT TECHNOLOGY OF THE PERMANENT CONNECTIONS

Cidyakin V. А., Lyuks D. I. — Installation for pipe adapters butt welding through the use of the low pressure arch in a cross magnetic field with the inverter power supply of an arch

The upgrading facility "STYK-3" is carried out in order to enable the pipe adapters welding from heterogeneous metals with a diameter up to 70 mm. In the facility an improved welding method is used, in which on the arc, burning in the gap between the ends of round billets, transverse magnetic field is superposed. Inverter power source of the low-pressure arc with a current up to 1500 A is developed. The source allows to change the alternating current frequency at welding, to use alternating current with different duration of positive and negative half-waves, move at a constant current of one or another polarity. Setting device with means for a transverse magnetic field creating, which enables the tube blanks assembly for welding outside the vacuum chamber is developed. Modernized System of the computer monitoring and the welding process control is modernized.
