The steelmaking furnace is mainly made of refractory materials, and the temperature of the steelmaking furnace is about 1600 ℃; Now let me introduce the temperature of steelmaking furnace.
In order to ensure the normal pouring, the tapping temperature should generally be about 1600 ℃, and the temperature of molten steel in the furnace should generally be more than 1600 ℃. This should take into account the temperature drop of molten steel out of the ladle. Of course, if there is a refining furnace, the temperature range can be appropriately widened, because the refining furnace can be heated. If there is no refining furnace, the temperature must be high enough, otherwise, the continuous casting can not be cast. It can be calculated in this way. If there is no refining furnace, the temperature of tapping process is generally 20 to 50 degrees, the temperature of argon blowing is 20 degrees, and the temperature of pouring ladle to tundish is about 40 degrees, and the temperature of tundish must not be lower than the liquid limit of molten steel. In this way, the temperature of molten steel in the furnace should not be lower than 1630 degrees, different steel types will have different liquid limits, and there will be a little temperature drop in the process of waiting for casting, According to different technological processes, the temperature of molten steel in the furnace will have different requirements.
