The main factors affecting the temperature of the melting pool of the steel package refining furnace are: blow-up mixing, vacuum degassing, etc. The control principle is that before the vacuum degassing, the initial steelmaking water due to the heat loss of the steel and steel package transport ation process, the steel package furnace lining heat absorption, the steel water temperature is reduced, so the temperature of the steel water must be heated to the specified temperature, so to ensure the smooth flow of vacuum degassing. The temperature of the steel liquid after vacuum degassing is to decrease, if it is lower than the temperature required for pouring, it must be heated again to meet the needs of the pouring operation.
