(1) Emergency treatment of cooling water

1) The dual power switch in the main power distribution cabinet of the electric furnace control room should be kept in the self-switching position. When the main power supply fails, the security power supply will automatically cut in, and then immediately restart the furnace water pump;

2) When the main power supply and the security power supply are cut off at the same time, immediately notify the electrician on duty, and prepare to start the emergency generator to ensure that the small water pump of the furnace body is powered and the furnace body cooling water is run. Therefore, diesel generators must be guaranteed to have a certain amount of diesel oil, and run together with the equipment once a month;

3) When the diesel generator cannot be started, tap water into the furnace body immediately;

4) Due to the power failure, the water supply of the coil is stopped, and the heat conducted from the molten iron is very large. If there is no water flow for a long time, the water in the coil may turn into steam, destroying the cooling of the coil, and the hose connected with the coil and the insulation of the coil will be burned out.
