| Popis: |
The slag bath accelerated formation technological processes in the "solid" start of mono-and bifilar process schemes are worked out. The melted electroslag steel 5ХНМ (5HNM) and 34ХН1М (34HN1M) properties satisfy to the requirements that apply to the open wrought metal smelting mechanical properties. It is found that an effective way to enhance productivity is the electroslag processes exothermic flux (slag, ferroalloys, and aluminum powder in amounts sufficient to exothermic reactions) use. It is experimentally proved that an electrically conductive layer exothermic flux presence allows electroslag process, both in mono and bifilar schemes in "solid" start. The 34ХН1М (34HN1M) steel in non-heat treated condition tend to hairline cracks formation. The heat treatment provides the required mechanical properties and the hairline cracks absence in electroslag molten metal. |
