Using exothermic mixtures in manual arc welding and electroslag processes
An exothermic flux with electrical conductivity in the solid state and producing rapidly a slag pool of the required volume in the starting period of the electroslag process with a 'solid' start instead of a 'liquid' start is developed. The chemical composition of the reduced met...

Summary: | An exothermic flux with electrical conductivity in the solid state and producing rapidly a slag pool of the required volume in the starting period of the electroslag process with a 'solid' start instead of a 'liquid' start is developed. The chemical composition of the reduced metal equivalent to the standard composition of 9KhF steel is described. In comparison with the existing methods of producing a slag pool, the electroslag processes using exothermic alloyed flux with the 'solid' start increase the yield of suitable metal by 2-7%, save 1.2-1.4 kWh for melting 1 kg of standard flux and reduce the duration of the starting period of the electroslag process by 25%. |
